1,8-Octanediol is a straight-chain C8 aliphatic diol used as a humectant and multifunctional preservative booster with inherent antimicrobial properties, distinct from 1,2-octanediol (caprylyl glycol).
A classic UVB-absorbing chemical sunscreen filter that also helps dissolve other filters.
A chemical UV filter often used to stabilize avobenzone.
A branched-chain fatty alcohol ester used as an emollient and co-solvent that provides a rich but non-sticky skin feel.
A nonionic surfactant used to solubilize oils into water-based formulas.
An ester of octyldodecanol and myristic acid. One of the lightest, most elegant esters used in skincare. Provides excellent spreadability and a dry, silky skin feel without greasiness.
An ester of octyldodecanol and pyrrolidone carboxylic acid (PCA) used as a rich emollient and skin-conditioning agent that combines the lubricating properties of a fatty ester with the moisturizing moiety of PCA.
An extract from evening primrose flowers with antioxidant and anti-inflammatory properties, distinct from the GLA-rich seed oil.
Extract from the flowers, leaves, and stems of Oenothera biennis (evening primrose). Complements the oil (from seeds) with water-soluble phenolic antioxidants.
A GLA-rich evening primrose oil that softens and calms dry, sensitive skin.
An extract from the seeds of Oenothera biennis (evening primrose), distinct from the GLA-rich expressed seed oil, used for antioxidant and skin-conditioning properties.
An oil-soluble fraction of Coix lacryma-jobi ma-yuen (Job's Tears) seed extract, distinct from the water-soluble form. Contains lipid-soluble bioactives including sterols and ceramide-analogous lipids.
A polyphenol-rich aqueous extract from olive fruit, distinct from olive oil. Delivers hydroxytyrosol and oleuropein — potent antioxidants that protect against UV-induced oxidative damage and calm inflammation.
Olive fruit oil, a rich emollient high in oleic acid and antioxidants.
Oil extracted from the husk/pomace of Olea europaea (olive) fruit after pressing. Similar fatty acid profile to olive fruit oil (primarily oleic acid) but with a lighter texture.
An extract from olive (Olea europaea) leaves, rich in oleuropein, hydroxytyrosol, and flavonoids. Provides potent antioxidant, anti-inflammatory, and mild antimicrobial benefits in skincare.
A pentacyclic triterpene naturally found in olive leaves, olive oil, and rosemary. In cosmetics, used for its antioxidant, anti-inflammatory, and mild tyrosinase-inhibiting (brightening) properties. Also studied for its role in supporting the skin's own ceramide synthesis pathway.
A naturally occurring omega-9 monounsaturated fatty acid (C18:1) found in many plant oils, used as an emollient and penetration enhancer that softens skin and replenishes surface lipids.
A polyethoxylated (10 EO units) ether of oleyl alcohol, used as a nonionic emulsifier and solubilizer in cosmetic emulsions and cleansers.
A polyethoxylated (3 EO units) ether of oleyl alcohol with a low HLB value, used as a co-emulsifier in cosmetic formulations to assist water-in-oil stability.
A phosphate ester of oleth-3 (polyethoxylated oleyl alcohol) used as an anionic co-emulsifier and surfactant in cosmetic emulsions, often combined with oleth-3.
A polyethoxylated (5 EO units) ether of oleyl alcohol with intermediate HLB, used as a nonionic emulsifier and co-solubilizer in cosmetic formulations.
An unsaturated C18 fatty alcohol derived from oleic acid. Used as a rich emollient, co-emulsifier, and thickener in creams and lotions; softens and conditions skin.
An ester of oleyl alcohol and erucic acid (C22:1) used as a lightweight, skin-softening emollient that imparts a silky, non-occlusive skin feel.
