The hydrochloride salt of the essential amino acid lysine, used in cosmetics as a humectant and skin-conditioning agent that also supports collagen production.

A triterpenoid component of Centella asiatica known for soothing and barrier-supporting effects.

A larger-molecule alpha hydroxy acid (AHA) often paired with glycolic or lactic acid; exfoliates the surface while being relatively gentle.

A large-molecule AHA that is gentle and good for sensitive skin.

A glyceryl triester of mixed plant-derived fatty acids (palm, olive, macadamia, rapeseed) used as an emollient in moisturizers.

A C14 saturated fatty acid used in cleansers as a saponified soap base and in creams as an emollient and emulsifier.

Natto gum is polyglutamic acid (PGA) — a biopolymer produced by Bacillus subtilis during the fermentation of soybeans (natto). It has extraordinary water-holding capacity, exceeding even hyaluronic acid. Used in Matsuyama's Hadauru ceramide line for superior moisturization.

Nicotinic acid, the free acid form of vitamin B3 (distinct from niacinamide/nicotinamide). At cosmetic use concentrations, functions as a skin conditioner and antioxidant. Included in Filorga Time-Filler 5-XP's NCEF complex alongside niacinamide and other B vitamins.

A naturally derived dicarboxylic acid (C18 unsaturated) produced by bioconversion of oleic acid; used in premium skincare as a mild skin-brightening and antimicrobial active.

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.

An aromatic carboxylic acid preservative booster used at 0.05–0.3% in acidic formulas to inhibit bacteria and moulds and reinforce primary preservative systems.

A C16 saturated fatty acid naturally found in skin sebum, used as an emollient and emulsifier to soften skin and stabilize creams.

The free acid form of vitamin B5, distinct from panthenol (the alcohol form) and calcium pantothenate (the salt form); used in cosmetics as a skin-conditioning agent contributing to moisture retention and barrier support.

A pentasodium salt of diethylenetriaminepentaacetic acid (DTPA) used as a chelating agent to bind trace metal ions and stabilize cosmetic formulas.

A synthetic acrylic copolymer incorporating pentylene glycol and glyceryl moieties used as a film-former and texture agent to improve skin feel and moisture retention.

An essential aromatic amino acid used in cosmetics as a humectant that contributes to the skin's natural moisturizing factor.

A water-soluble UVB UV filter (Ensulizole). Approved by FDA and EU (up to 4%). Converts UV energy to heat. Best used in combination with UVA filters due to its narrow UVB-only spectrum.

The free-acid form of phytate (myo-inositol hexaphosphoric acid) used in cosmetics primarily as a chelating agent and mild brightening active; distinct from Sodium Phytate.

A linear homopolymer of acrylic acid used as a thickener and film-forming agent in cosmetics; unlike Carbomer it is uncrosslinked, resulting in different rheological behavior.

A polysaccharide polymer built from glucuronic acid units; acts as a humectant and film-former, providing hydration and a protective surface layer.

A large humectant that holds water at the skin surface; pairs well with hyaluronic acid.

A polymeric hydroxystearic acid used in sunscreens and color cosmetics as a dispersant for mineral UV filter pigments, reducing white cast and improving application feel.

The potassium salt of aspartic acid, used in cosmetics as a skin-conditioning agent that provides both a mineral component (potassium) and an amino acid (aspartate) associated with cellular energy metabolism.
