Every ingredient SkinAtlas knows about — all 2277 of them. What each one does, what it works well with, and what to watch for.
A short-chain polyethylene glycol (MW ~300 Da) used primarily as a solvent and humectant. Increases water-binding capacity and improves the texture and feel of toners and essences.
A PEGylated glyceride emulsifier derived from coconut caprylic/capric fatty acids, used to solubilize and emulsify oils in water-based cosmetic systems.
A low-ethoxylation hydrogenated castor oil (6 EO units) used as a mild nonionic emulsifier and solubilizer in lotions and toners.
A PEGylated almond glyceride used as a mild nonionic emulsifier and solubilizer, popular in cleansing balms and rinse-off products.
A polyethylene glycol ester of glyceryl isostearate used as an emulsifier and solubiliser in Japanese cosmetics. Provides good skin feel and is tolerant of high electrolyte concentrations.
A polyethoxylated hydrogenated castor oil used as a nonionic emulsifier and solubilizer for oils and fragrance compounds in cosmetics.
A complex ester combining PEG-60 hydrogenated castor oil with pyroglutamic acid (PCA) isostearate. Provides gentle emulsification and skin-conditioning benefits. Used in Minon's sensitive-skin sheet masks.
A high-molecular-weight polyethylene glycol (MW ~6000 Da, ~136 EO units). Used as a thickener and binder in cosmetics.
A dimethicone copolymer with 7 polyethylene glycol (PEG) side chains that confer water solubility. Functions as an O/W emulsifier and skin conditioner, combining silicone's signature smoothness with aqueous compatibility. Commonly used in watery creams, gel moisturizers, and lightweight foundations. Distinct from PEG-10 Dimethicone (10 PEG units, more water-soluble) and PEG-12 Dimethicone.
A PEGylated glyceryl cocoate derived from coconut oil used as a gentle nonionic surfactant and emulsifier in facial washes and masks.
A PEG-7 ester of glyceryl isostearate. Functions as an emulsifier and skin conditioner, particularly in water-in-oil emulsions like Elixir's brightening emulsions.
A PEG derivative of coconut alcohol and trimethylolpropane that functions as an emulsifier, surfactant, and emollient in cosmetic formulations.
A medium-chain polyethylene glycol used as a humectant and solvent that helps retain moisture and improve formula texture.
A PEGylated meadowfoam seed oil (Limnanthes alba) used as a lightweight emollient and emulsifier that imparts a silky skin feel.
A short-chain polyethylene glycol used as a humectant and solvent to hydrate skin and improve the feel and spreadability of formulas.
A polyethylene glycol derivative of beeswax used as a mild nonionic emulsifier and conditioning emollient in cleansing balms and creams.
Shorter-chain PEG ester emulsifier paired with PEG-12 Diisostearate in cleansing oils to achieve clean rinse-off with minimal stripping.
A PEG-8 ester of glyceryl isostearate used as a mild nonionic emulsifier and solubilizer in cleansing oils and rinse-off products.
PEG-8 Isostearate is a polyethylene glycol (8 EO units) ester of isostearic acid. It is a lipophilic surfactant used as a co-emulsifier and solubilizer in cleansing oil and balm formulations. The shorter PEG chain (8 units vs 10 or 20) makes it more hydrophobic than longer-chain analogues, contributing more to the oil-phase stabilization than to water rinseability.
A PEG-8 ester of lauric acid used as a mild nonionic emulsifier to stabilize oil-in-water emulsions in sunscreens and moisturizers.
A PEG-8 ester of stearic acid used as a mild nonionic emulsifier to stabilize oil-in-water emulsions in face creams and lotions.
A dimethicone functionalized with PEG-9 groups. A silicone surfactant that emulsifies water-in-silicone systems. Used in Elixir Spot Clear Serum and Kiku-Masamune sake emulsion for silky texture.
A silicone-PEG copolymer emulsifier used in BB creams and sunscreens to create stable, water-resistant silicone-in-water emulsions.
A high-molecular-weight polyethylene glycol (~90 ethylene oxide units, ~4000 Da) used as a humectant and mild thickener in skincare formulas.
