What is PPG-3 Myristyl Ether and how does it compare across the PPG-ether series?
PPG-3 myristyl ether (CAS 63793-60-2, C23H48O4) is a low-propoxylation myristyl (C14) alcohol polypropylene-glycol ether. With only about 3 PPG units it is among the most oil-soluble, lightest-feel grades in the PPG-ether family, used as an emollient, spreading agent and solvent. Higher-PPG grades (PPG-10 cetyl, PPG-11/15 stearyl, PPG-14 butyl) raise the propoxylate content. Bulk quantities are sourced to specification.

How to choose: These are polypropylene glycol (PPG) ethers of fatty alcohols — nonionic emollients and solvents. Unlike a PEG (ethoxylate) chain, the PPG (propoxylate) chain is lipophilic, so more PPG units raise oil-solubility, spreadability and pigment-wetting while keeping the grade oil- rather than water-soluble. The alkyl cap sets the skin-feel: the long C16-C18 cetyl and stearyl ethers give a richer, more substantive conditioning emolliency, while the short butyl ether is a lighter, more solvent-like carrier and coupling agent.

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 →PPG-3 Myristyl Ether (INCI PPG-3 Myristyl Ether; CAS 63793-60-2) is a light, water-resistant emollient and spreading agent — myristyl (C14) alcohol with about three units of propylene oxide. It spreads easily, leaves a smooth, low-tack, water-resistant film and wets pigments well, which makes it a useful skin-feel and color-cosmetic emollient and a wetting aid.
What is PPG-3 myristyl ether?
It is a short polypropylene-glycol ether of myristyl alcohol. The few propylene-oxide units give oil compatibility, water resistance and a light, dry feel, while the C14 tail provides emolliency and pigment wetting. It is a clear, low-viscosity liquid.
Applications by sector
Skin & sun care. A light, water-resistant emollient and spreading agent that improves rub-out and wear in lotions, sunscreens and antiperspirants. Color cosmetics. A pigment-wetting emollient with a smooth, low-tack finish. Antiperspirant/deodorant. A low-residue carrier for actives. These describe formulation behavior, not skin-health claims.

Frequently Asked Questions
What is PPG-3 myristyl ether used for?
PPG-3 myristyl ether (CAS 63793-60-2) is a light, water-resistant emollient and spreading agent used to improve rub-out and wear in skin care, sun care and antiperspirants, and to wet pigments in color cosmetics.
Is PPG-3 myristyl ether water resistant?
Yes — the propylene-oxide units make it oil-compatible and water-resistant with a dry, low-tack feel, which supports wear in sun and antiperspirant products.
What is the CAS of PPG-3 myristyl ether?
It is CAS 63793-60-2. As a polyether it is a defined-average material supplied to a grade; the CoA documents each lot.
How is bulk PPG-3 myristyl ether 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.
