What is PPG-14 Butyl Ether and how does it compare across the PPG-ether series?
PPG-14 butyl ether (CAS 9043-30-5, C30H62O10) is a short butyl (C4) capped polypropylene-glycol ether with about 14 PPG units. Its small alkyl cap makes it a lighter, more solvent-like carrier than the long-chain emollient grades (PPG-3 myristyl, PPG-10 cetyl, PPG-11/15 stearyl), serving as a coupling agent, moisture-control agent and synthetic base fluid. Bulk quantities are sourced to specification.

- ▸ Functional fluids: Component of hydraulic and metalworking fluids
- ▸ Solvent systems: Coupling agent and solvent for industrial formulations

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.

Request SDS →PPG-14 Butyl Ether (INCI PPG-14 Butyl Ether; CAS 9043-30-5) is a polypropylene-glycol butyl ether — a water-resistant emollient and functional fluid. In personal care it gives a light, smooth, water-resistant skin feel and helps disperse pigments; in industrial use it serves as a functional fluid, solvent and defoamer. It is a clear, low-color liquid.
What is PPG-14 butyl ether?
It is butanol initiated with about 14 units of propylene oxide — a polypropylene-glycol monobutyl ether. The propylene-oxide backbone makes it oil-compatible and water-resistant with a light, non-greasy feel, while the molecule retains enough surface activity to spread well and disperse pigment.
Applications by sector
Personal care. A water-resistant emollient and slip agent in sunscreens, antiperspirants, lotions and color cosmetics, where it improves wear, reduces tack and disperses pigment. Industrial. A functional fluid, solvent and defoamer in metalworking, coatings and process applications. Match the grade to the feel or fluid performance you need.

Frequently Asked Questions
What is PPG-14 butyl ether used for?
PPG-14 butyl ether (CAS 9043-30-5) is used as a water-resistant emollient and pigment-dispersing slip agent in sunscreens, antiperspirants and color cosmetics, and as a functional fluid, solvent and defoamer in industrial applications.
Is PPG-14 butyl ether water resistant?
Yes — the propylene-oxide backbone makes it oil-compatible and water-resistant, which is why it is used to improve wear and reduce tack in sun and antiperspirant formulas.
What is the CAS of PPG-14 butyl ether?
It is CAS 9043-30-5. As a polyether it is a defined-average material supplied to a grade; the CoA documents each lot.
How is bulk PPG-14 butyl 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.
What is the REACH and TSCA regulatory status of PPG-14 Butyl Ether?
PPG-14 Butyl Ether (CAS 9043-30-5) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 500-241-6).
