What is isoamyl cocoate and what is it used for?
Isoamyl cocoate (isoamyl laurate, CAS 6309-51-9) is a light coconut-derived branched-chain ester. It is used in cosmetic and personal-care formulations as a light-feel emollient, a skin-conditioning ester, and an oil-phase spreading agent.
ISOAMYL LAURATE- ▸ Emollient: light-feel skin-softening ester (EPA Safer Chemicals emollient class)
- ▸ Skin conditioning: cosmetic conditioning ester for emulsions
- ▸ Oil-phase base: spreading agent in personal-care formulas
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Isoamyl cocoate (INCI Isoamyl Cocoate; CAS 6309-51-9) is a light, dry, fast-spreading emollient ester — the ester of isoamyl (isopentyl) alcohol with coconut-derived fatty acids. It has very low viscosity and a dry, non-greasy, weightless skin-feel, which makes it a coconut-sourced emollient that formulators reach for as a dry-touch spreading agent and a carrier for oils, actives and pigments. Identity: PubChem.
What is isoamyl cocoate?
It is a branched short-chain ester — isoamyl alcohol esterified with the fatty acids of coconut oil (predominantly lauric). The branched, short alcohol gives a very low viscosity and a fast-spreading, dry, low-residue finish, comparable in feel to volatile silicones and light hydrocarbons. It is supplied as a clear, low-odor liquid and is sourced from coconut-derived feedstock; this describes its origin and physical behavior, not an environmental or skin-health claim.
Applications by sector
Skin care. A light, dry-touch emollient and spreading agent in lotions, creams, sunscreens and sprays, where it cuts greasiness and improves slip. Color cosmetics. A pigment-wetting and lay-down aid with a dry finish in foundations and makeup. Sun & antiperspirant/deodorant. A low-residue carrier and solvent for filters and actives. Hair care. A light, non-greasy slip and gloss agent. Formulators often use it as a plant-derived alternative to volatile silicones for a dry feel; match the ester to the spread and finish your formula needs. These are formulation-feel roles, not skin-health claims.

Frequently Asked Questions
What is isoamyl cocoate used for?
Isoamyl cocoate (CAS 6309-51-9) is a light, dry-touch emollient ester used as a spreading agent and carrier in skin care, color cosmetics, sun care and hair care — often as a coconut-derived alternative to volatile silicones for a dry, non-greasy feel.
Is isoamyl cocoate a natural/plant-based ester?
It is made from coconut-derived fatty acids, so it is plant-sourced; we describe its origin and its formulation behavior (light, dry, fast spread) rather than making an unqualified “natural” or “clean” marketing claim. Confirm any certification you require against the specification.
How does isoamyl cocoate compare to isopropyl myristate?
Both are light, fast-spreading emollient esters. Isoamyl cocoate is coconut-derived with a notably dry finish; isopropyl myristate is a benchmark light ester with strong solvency. Choose by feel, spread and origin; see the emollient ester selection guide.
What is the CAS of isoamyl cocoate?
It is CAS 6309-51-9 (PubChem CID 61386). As a coconut-derived ester it is supplied to a grade specification; the CoA documents each lot.
How is bulk isoamyl cocoate supplied and quoted?
RawSource supplies it as a liquid in bulk with CoA and SDS per lot. Pricing is quote-based on grade and volume; submit an RFQ with your target quantity.
