Key takeaways
- Rosehip seed oil is a cold-pressed fixed oil from the seeds, not a rose essential oil or a fruit powder. It is pressed from the seeds inside the hip (fruit) of Rosa canina and its relatives; rose otto/absolute (steam-distilled or solvent-extracted from Rosa damascena petals) and rosehip fruit/shell powder are entirely different materials with different specs, prices and uses.
- The fatty-acid profile is the specification. Authentic Rosa canina seed oil is a polyunsaturated-rich oil dominated by linoleic acid (omega-6, typically ~44-55%) and alpha-linolenic acid (omega-3, typically ~16-35%), with oleic acid (typically ~14-20%) and low saturates. That ~65-70% polyunsaturated load defines its performance and its instability.
- The INCI name depends on plant part, and both forms exist. The seed-pressed oil is Rosa Canina Seed Oil; oil declared from the whole fruit is Rosa Canina Fruit Oil (CosIng REF 79666 / 34901; CAS 84696-47-9). The RFQ must state which, because they are labelled differently.
- Because it is highly unsaturated, oxidation is the central quality risk. Peroxide value, acid value, colour and odour move fast; require numeric COA limits, light/oxygen-protective packaging and a realistic shelf-life-with-storage statement rather than an open-ended one.
- Arovela sells documented Turkish supply, not certificate inflation. Arovela holds ISO 22000, ISO 9001 and ISO 27001; organic, COSMOS and cosmetic-safety documentation are buyer-side or lot-specific requirements that must be named in the RFQ. Arovela serves EU and Ukraine markets from Turkey.
Introduction
Rosehip seed oil is one of the most misunderstood materials on a natural-products offer sheet, because three unrelated products hide behind adjacent names. There is the cold-pressed fixed oil pressed from the seeds inside the rosehip — the subject of this guide. There is rose essential oil (rose otto and rose absolute), a volatile aromatic material distilled or extracted from Rosa damascena flower petals, sold by the gram at a completely different price point. And there is rosehip fruit or shell powder, a food and supplement ingredient valued for vitamin C and fruit polyphenols, which contains little of the seed oil at all. A buyer who conflates them will approve the wrong specification, the wrong test panel and the wrong price.
This guide is written for procurement, QA and cosmetic-formulation teams sourcing rosehip seed oil from Turkey — a major wild-harvest origin for Rosa canina — and comparing it against Chilean Rosa mosqueta (R. rubiginosa) and Eastern European supply. It covers the botanical and product-form distinctions, the fatty-acid profile that functions as the core spec, the natural provitamin-A/retinoid and tocopherol context that formulators care about, refined versus virgin and cold-press versus CO2 extraction, the oxidation and storage problem, the INCI and EU cosmetic framing, and the MOQ, packaging, RFQ and COA language that prevents disputes. For adjacent detail, read the Arovela guides on sourcing essential oils for cosmetic formulators, Turkish rosehip bulk botanicals and natural-products COA red flags.
One plant, three products: seed oil vs rose oil vs fruit powder
The confusion is worth resolving before any number is discussed, because it drives everything downstream.
Rosehip seed oil is the fixed (non-volatile) oil obtained by pressing the small seeds found inside the hip, the accessory fruit that forms after the rose flower fades. It is a light, dry-feel carrier oil used almost entirely in skincare and cosmetics. It does not smell of roses; a faint nutty, slightly earthy odour is normal.
Rose essential oil — rose otto (steam-distilled) or rose absolute (solvent-extracted) — is a volatile aromatic oil from Rosa damascena or Rosa centifolia petals. It is one of the most expensive materials in perfumery, dosed in fractions of a percent, and shares nothing with the seed oil except the genus. For that material, see the Arovela Rosa damascena / Isparta rose oil wholesale guide.
Rosehip fruit / shell powder is milled from the dried flesh (and sometimes the whole hip). It is a food and supplement ingredient prized for vitamin C, carotenoids and fruit polyphenols, and is the basis of rosehip tea and joint-health supplements. It is not an oil and is not interchangeable with either of the above.
The practical rule: an RFQ that says only "rosehip oil" is not a specification. State plant part and product form — cold-pressed seed oil — and require the supplier to confirm it on paper. A supplier who cannot distinguish these three on a spec sheet is one whose COA you cannot trust.
The fatty-acid profile is the specification
Rosehip seed oil is defined commercially by its fatty-acid composition. Unlike an essential oil, there is no single aroma marker; the value proposition is the balance of essential fatty acids, and that balance is what a laboratory measures by GC-FID (fatty-acid methyl esters, FAME) to confirm identity and screen for dilution with cheaper oils.
The material is genuinely unusual among carrier oils: roughly 65-70% of the fatty acids are polyunsaturated, split between omega-6 (linoleic) and omega-3 (alpha-linolenic). That is one of the highest polyunsaturated fractions of any commonly used facial oil — and it is the reason the oil performs well on skin but oxidises quickly on the shelf.
The table below gives typical GC ranges for authentic Rosa canina seed oil, compiled from published compositional studies. Treat these as identity and plausibility bands, not a single legal specification: species (R. canina vs R. rubiginosa/mosqueta vs other Rosa spp.), wild vs cultivated origin, crop year, harvest stage and extraction all move the numbers. Verify the exact band on your approved sample.
| Fatty acid | Class | Typical range (% of FAME) | Role / note |
|---|---|---|---|
| Linoleic acid (C18:2, omega-6) | Polyunsaturated | ~44-55% | Dominant marker; defines the profile |
| Alpha-linolenic acid (C18:3, omega-3) | Polyunsaturated | ~16-35% | Second major marker; wide range across species/origin |
| Oleic acid (C18:1, omega-9) | Monounsaturated | ~14-20% | Main monounsaturate; rises in some Rosa spp. |
| Palmitic acid (C16:0) | Saturated | ~2-4% | Minor saturate |
| Stearic acid (C18:0) | Saturated | ~1.5-3% | Minor saturate |
| Gadoleic / other minors | Mixed | usually low single digits | Secondary identity confirmation |
Two practical points follow. First, because the oil is defined by its two polyunsaturates, an offer whose GC shows an unusually high oleic and low linoleic/linolenic balance may be a different Rosa species, a different crop, or a cut with a cheaper high-oleic oil — worth a question, not an automatic rejection. Second, the same polyunsaturated richness that formulators pay for is exactly what makes peroxide value and shelf life a live issue, which is why the storage section below is not boilerplate.
Published Turkish and international studies converge on this pattern: for example, Rosa canina seed-oil surveys report linoleic acid around 48-54%, alpha-linolenic around 16-19% and oleic around 15-19%, while broader multi-species datasets show linoleic averaging in the mid-40s, linolenic near 19% and oleic near 25%. See an open PubMed-indexed review of Rosa canina and its by-products for the underlying chemistry: Rosa canina L. bioactive properties and applications (PMC).
Provitamin A, natural retinoic acid and tocopherols: the cosmetic context
Rosehip seed oil's reputation in skincare rests partly on minor bioactives beyond the fatty acids, and this is where buyers must be careful to keep claims on the brand's side of the line.
The oil naturally contains carotenoids (provitamin A, chiefly beta-carotene), small and variable amounts of naturally occurring trans-retinoic acid and related retinoids, tocopherols (vitamin E), phytosterols, squalene and trace vitamin C and phenolics. Cold-pressed unrefined oil retains far more of these than refined oil; cold pressing has been reported to raise all-trans-retinoic acid content markedly versus harsher extraction, and cold-pressed tocopherol content can be high (studies report figures ranging from tens of mg/100 g up to around 1000+ mg/kg depending on material and method).
Two cautions for a B2B specification:
- These bioactives are low and variable, and they degrade. Studies show cold-pressed rosehip oil stored unrefrigerated can lose the majority of its carotenoids and a large share of its tocopherols within about a month. A carotenoid or retinoid figure on a COA is a snapshot at release, not a guaranteed level at the point of use — so tie any such value to a fresh sample and defined storage.
- The cosmetic efficacy claims are the buyer's regulatory responsibility. "Natural retinoid," "regenerating," "anti-ageing" and similar positioning are finished-product claims that a cosmetic brand must substantiate under its own regime. A raw-material supplier can report composition; it cannot license a skin-benefit claim. Keep the RFQ focused on measurable composition and let the brand own the marketing.
For formulators, the useful takeaway is that if the reason for choosing rosehip seed oil is its retinoid/carotenoid character, then cold-pressed, unrefined, freshly pressed and well-protected oil is the grade to specify — and the price and shelf-life trade-offs that come with it should be accepted deliberately.
Refined vs virgin, and cold-press vs CO2
Two independent axes describe how the oil is made, and both belong in the RFQ.
Virgin / unrefined vs refined. Unrefined (virgin) cold-pressed oil keeps the colour (golden to reddish-orange from carotenoids), the characteristic odour and the maximum bioactive load, but it is less stable and less uniform batch to batch. Refined oil is lighter in colour and odour, more consistent and often more stable, but stripped of much of the carotenoid/tocopherol character that motivates the ingredient in the first place. Neither is "better" in the abstract — the choice depends on whether the brand is selling the bioactive story or wants a neutral, stable emollient.
Cold-press vs supercritical CO2. Cold pressing (mechanical expeller, kept low-temperature) is the traditional route: it preserves heat-sensitive fatty acids, tocopherols and phenolics well but gives a lower yield (studies report around 5%) and a more variable product. Supercritical CO2 extraction runs solvent-free at low temperature and can give a higher yield (around 6.5% reported) with excellent recovery of carotenoids and tocopherols in optimised fractions, at higher processing cost. Both are legitimate; what matters for the buyer is that the extraction method is stated and consistent lot to lot, because it shapes both the minor-bioactive profile and the stability. For the broader extraction trade-off logic, see the Arovela CO2 vs ethanol extraction guide.
| Attribute | Cold-pressed, unrefined | Supercritical CO2 | Refined |
|---|---|---|---|
| Typical oil yield | Lower (~5%) | Higher (~6.5%) | Depends on feed oil |
| Carotenoids / retinoids | Highest retained | High (fraction-dependent) | Largely removed |
| Tocopherols (natural E) | High | High | Reduced |
| Colour / odour | Golden-orange, characteristic | Golden, characteristic | Pale, near-neutral |
| Batch consistency | More variable | Good | Most consistent |
| Oxidative stability | Lowest | Moderate | Higher |
| Typical positioning | "Actives" story, virgin claims | Premium solvent-free | Neutral emollient base |
Oxidation, peroxide value and storage: the real quality risk
This is the section that separates a serious rosehip seed oil specification from a naive one. Because the oil is ~65-70% polyunsaturated, it is inherently prone to lipid peroxidation — a chain reaction driven by light, heat, oxygen and trace metals that generates peroxides and, later, aldehydes (hexanal, nonanal) responsible for the rancid odour. An unstabilised, poorly packed rosehip oil can begin to turn within months.
The measurable controls are standard fixed-oil chemistry, and they belong on the COA as numeric values with limits, not as pass/fail text:
| Parameter | Why it matters | Typical control |
|---|---|---|
| Peroxide value (PV) | Primary oxidation marker; rises first | Low at release (e.g. single digits meq O2/kg); agree a max |
| Acid value / free fatty acids | Hydrolytic rancidity, poor handling | Low; agree a max |
| Fatty-acid profile (GC-FID) | Identity + dilution screen | Within the agreed band (see table above) |
| Colour / odour | Sensory oxidation gate | Characteristic golden-orange; no rancid note |
| Iodine value | Reflects unsaturation/identity | Consistent with a high-PUFA oil |
| Tocopherol / added antioxidant | Natural stability + any ROE/tocopherol added | Stated if the oil is stabilised |
Storage and packaging are part of the specification, not an afterthought:
- Protect from oxygen and light. Use amber glass or lined/opaque containers, tight closures and minimal headspace; nitrogen blanketing of bulk drums is common and worth requesting for larger volumes.
- Keep it cool and dark, ideally under about 30 degrees C, away from UV and heat sources.
- Consider stabilisation. Many suppliers add a natural antioxidant such as rosemary extract (ROE) or mixed tocopherols; if so, it must be declared for label and formulation purposes.
- Agree a realistic shelf life with a retest date and storage conditions in writing. Rosehip seed oil is a short-shelf-life oil; an open-ended "2 years, ambient" claim on an unstabilised virgin oil is a red flag. Ask for a retest point rather than assuming an indefinite life.
INCI, CosIng and EU cosmetic context (buyer-side)
For cosmetic use in the EU, the labelling and compliance obligations sit with the importer/brand, not with the raw-material certificate. Three points anchor the paperwork.
INCI name follows the plant part. Oil pressed from the seeds is Rosa Canina Seed Oil; oil declared from the whole fruit is Rosa Canina Fruit Oil. Both are catalogued in the EU cosmetic ingredient database (CosIng) — Rosa Canina Fruit Oil, CosIng REF 79666 / 34901, CAS 84696-47-9, EC 283-652-0, with functions listed as emollient (and humectant for the fruit oil) — so the RFQ must state which form is being supplied and how it should be declared. You can confirm the entry in the European Commission's CosIng cosmetic ingredient database.
COSMOS / organic is a buyer-side claim. If a formulation needs COSMOS-approved or certified-organic rosehip oil, that is a certified-material requirement to be named in the RFQ and evidenced by the relevant certificate — it is not implied by a supplier's ISO 22000/9001/27001 systems. Do not let a management-system certificate stand in for a COSMOS or organic claim.
EU Cosmetic Regulation duties are the brand's. Product safety assessment, the PIF (Product Information File), CPNP notification and any claim substantiation under Regulation (EC) 1223/2009 are the responsible person's obligations. The raw-material COA supports these but does not discharge them. Where the oil is also positioned for food/supplement use, separate food-contaminant controls apply — see the Arovela note on EU fragrance allergen labelling for the adjacent cosmetic-labelling discipline, and keep cosmetic and food pathways distinct.
None of these obligations is satisfied by an ISO 22000/9001/27001 statement. Those describe Arovela's management systems; cosmetic-safety, COSMOS/organic and claim compliance are separate, buyer-side requirements the RFQ should name explicitly. See the Arovela certifications page for exactly what is and is not held.
MOQ, packaging and shipment
Rosehip seed oil is a moderate-yield pressed oil, so pricing and minimum quantities reflect the volume of seed processed per kilo of oil, the species/origin and whether the grade is virgin or refined. The bands below are planning guidance for RFQ scoping, not stock promises.
- Sample / trial. Small evaluation volumes (for example, 100 g to a few kilograms) are normal for GC, PV and sensory approval before a commercial order — and, given the short shelf life, samples should be fresh and tested promptly.
- Commercial lots. Regular purchasing commonly moves in tens of kilograms upward, priced by lot, grade and origin.
- Programme volumes. Private-label or standing supply may justify larger, scheduled shipments with agreed retest points and, for bulk, nitrogen-blanketed drums.
Packaging must protect the oil from its two main enemies, oxygen and light. Standard formats are amber glass or lined/opaque HDPE for smaller quantities and food-grade lined steel or HDPE drums (ideally nitrogen-flushed) for bulk, all with tight closures and minimal headspace. Store cool, dark and sealed; keep the oil away from strong-odour materials. Because oxidation is a real and fast risk for this oil specifically, agree a shelf-life statement, a retest date and storage conditions in writing rather than assuming an open-ended life. For the sampling discipline itself, see the Arovela B2B sample order best practices.
RFQ and COA language that prevents disputes
Direct wording removes ambiguity on both sides. A workable clause set for rosehip seed oil:
"Material shall be cold-pressed (or supercritical-CO2-extracted, as specified) fixed oil of Rosa canina L. seed — not rose flower essential oil and not rosehip fruit/shell powder — declared as Rosa Canina Seed Oil (INCI). State whether virgin/unrefined or refined. Supplier shall provide, per lot, a COA stating: fatty-acid profile by GC-FID (linoleic, alpha-linolenic, oleic and minor acids, % FAME) within the agreed band; peroxide value and acid value with maxima; iodine value; colour and odour; and any added antioxidant (e.g. rosemary extract or tocopherols) declared. COA shall state botanical name and plant part, species, extraction method, origin, lot number, pressing/extraction date, methods and laboratory. Where destined for EU cosmetic use, supplier shall confirm the INCI declaration and provide documentation to support the buyer's safety assessment; any organic/COSMOS status shall be separately certified. Packaging shall protect from light and oxygen (amber/opaque, nitrogen-blanketed for bulk); supplier shall state shelf life, retest date and storage conditions."
Then match the paperwork before scaling: confirm that the approved sample, quotation, pro forma invoice, packing list and COA all describe the same material — same species, same plant part, same grade, same fatty-acid band and same extraction method. That single discipline catches most silent substitutions (a different Rosa species, a refined oil sold as virgin, or a cheaper high-oleic cut) before goods move.
Frequently asked questions
What fatty-acid ranges should I expect in genuine rosehip seed oil?
For authentic Rosa canina seed oil, expect linoleic acid (omega-6) typically around 44-55%, alpha-linolenic acid (omega-3) typically around 16-35%, and oleic acid typically around 14-20% of the fatty-acid methyl esters, with low saturates — an oil that is roughly 65-70% polyunsaturated overall. The exact band shifts with species (R. canina vs R. rubiginosa/mosqueta), wild vs cultivated origin, crop year and extraction, so treat any specific target as something to confirm on the approved sample by GC-FID rather than a fixed universal number.
Is rosehip seed oil the same as rose oil or rosehip fruit powder?
No. Rosehip seed oil is a cold-pressed fixed oil from the seeds inside the hip, used mainly in skincare. Rose oil (rose otto/absolute) is a volatile essential oil distilled or extracted from Rosa damascena petals for perfumery — a different material at a vastly different price. Rosehip fruit/shell powder is a milled food/supplement ingredient valued for vitamin C and fruit polyphenols, not an oil. Always state plant part and product form in the RFQ.
Why does rosehip seed oil go rancid, and how do I control it?
Because it is about 65-70% polyunsaturated, it is highly prone to lipid peroxidation from light, heat, oxygen and trace metals, which generates peroxides and rancid aldehydes. Control it by requiring low peroxide value and acid value on the COA, specifying light- and oxygen-protective packaging (amber/opaque, nitrogen-blanketed for bulk, minimal headspace), cool dark storage, any added natural antioxidant declared, and a realistic shelf life with a retest date — never an open-ended "2 years ambient" claim on an unstabilised virgin oil.
Which INCI name and documents do I need for EU cosmetic use?
Declare seed-pressed oil as Rosa Canina Seed Oil (or Rosa Canina Fruit Oil if supplied from the whole fruit; CosIng REF 79666/34901, CAS 84696-47-9). The safety assessment, PIF, CPNP notification and claim substantiation under Regulation (EC) 1223/2009 are the brand's responsibility; the supplier's COA supports but does not replace them. Any organic or COSMOS status must be separately certified and is not implied by ISO 22000/9001/27001.
