A class of polyethylene glycol / polypropylene glycol block copolymers used as solubilizers and emulsifiers in Japanese toners and serums, helping blend silicone and oil-soluble actives into water-based formulas.
A nonionic polyoxyethylene/polyoxypropylene ether surfactant used to solubilize and emulsify in watery lotions.
A mixed polyethylene glycol and polypropylene glycol dimethyl ether used as a solvent and carrier to improve formula texture and ingredient delivery.
A mixed polyethylene glycol and polypropylene glycol dimethyl ether used as a solvent and carrier to improve formula texture and ingredient delivery.
A silicone-PEG/PPG copolymer with equal PEG-18 and PPG-18 side chains that acts as an emulsifier and slip agent for water-compatible silicone formulas.
A block copolymer of PEG (9 units) and PPG (2 units) capped with methyl ether groups. Used as a co-solvent in sunscreen formulas for dissolving organic UV filters. Common in Anessa and Shiseido SPF products.
A triblock glycerin copolymer combining PEG-8, PPG-5, and polybutylene glycol-3 used as a multifunctional humectant to attract and retain moisture in serums and boosters.
A copolymer combining polyethylene oxide (POE/PEG) and dimethicone segments. Acts as an emulsifier and sensory enhancer in lotions and toners.
A polyoxyethylene-methylpolysiloxane copolymer (Japanese JSCI name for PEG-dimethicone). Functions as an emulsifier and skin-conditioning agent with a light, silky texture. Used in Shiseido d program acne-care lotion.
A propylene glycol ether of methyl glucose with approximately 10 propylene oxide units. Functions as a humectant in skincare formulations, particularly toners and serums.
A propoxylated methyl glucose ether used as a mild humectant and skin conditioner in toners, essences, and lotions, imparting a smooth, non-greasy hydration.
A copolymer of polypropylene glycol and SMDI (4,4'-methylenediphenyl diisocyanate) used as a film-former and emollient that imparts a silky, velvety skin feel.
A polymeric nonionic surfactant combining a polypropylene glycol backbone with a branched long-chain ethoxylate, used as an emulsifier and solubilizer in premium aqueous skin-care formulas.
A polypropylene glycol ether of stearyl alcohol; functions as a lightweight emollient and skin-conditioning agent commonly used in cleansing oils.
A polypropylene glycol polymer (17-unit chain) used as a humectant and co-solvent in cosmetics. Lighter and less viscous than glycerin; often combined with it in Japanese toners.
A condensation product of propylene glycol and the amino acid arginine. Used as a mild skin conditioner in cleansing and care products.
A propylene glycol ether of methyl glucose with approximately 20 propylene oxide units. Used as a humectant and skin-conditioning agent in toners and essences.
A nonionic polypropylene glycol/butyl ether copolymeric surfactant used as a solubilizer and emulsifier in toners and facial preparations.
A diester of tripropylene glycol (PPG-3) and pivalic acid. A lightweight, non-greasy emollient used in skincare to improve spreadability and provide a dry, silky skin feel. Common in Shiseido premium formulations.
A polypropylene glycol ether of myristyl alcohol used as a lightweight emollient and carrier solvent that imparts a silky skin feel and improves the spreading and dispersibility of actives in serums and sunscreens.
A complex polyol ether combining PPG-4 and ceteth-20 groups. Used as a non-ionic emulsifier and surfactant in skincare formulations.
PPG-5-Laureth-5 is a non-ionic surfactant made by sequential propoxylation (5 PO units) and ethoxylation (5 EO units) of lauryl alcohol. The resulting molecule has a mixed hydrophilic/lipophilic character suitable for use as a mild solubilizer and co-emulsifier in water-based skincare. Used in toners and serum-type products to solubilize fragrance compounds and provide a smooth, conditioned skin feel.
A high-propoxylation methyl glucose ether derived from corn glucose and propylene oxide, used as a humectant and mild emollient that provides lasting moisturization without a heavy or tacky feel.
A polypropylene glycol/polyethylene glycol ether of decyltetradecanol used as an emulsifier and solubiliser in Japanese toners and essences. Enables stable, clear-to-slightly-translucent formulas.
