Ingredient library
Every ingredient SkinAtlas knows about — all 2165 of them. What each one does, what it works well with, and what to watch for.
Ring-shaped oligosaccharides (α, β, or γ forms) that form inclusion complexes with actives and fragrances to improve their stability, solubility, and skin delivery; distinct from the chemically modified Hydroxypropyl Cyclodextrin.
An extract from Cymbopogon citratus (West Indian lemongrass), distinct from the Cymbopogon schoenanthus (camel grass) entries in the KB; contains citral and flavonoids and is used for its refreshing scent and antioxidant properties, though its citral content carries sensitization risk.
The oxidized dimer of cysteine formed by a disulfide bond between two cysteine molecules; used in cosmetics as a conditioning amino acid with roles in keratin integrity and as a precursor to antioxidant glutathione — distinct from cysteine (the monomer free thiol form).
A modified form of xanthan gum where the side-chain carboxyl groups have been partially dehydrated, altering its electrolyte tolerance and rheological behavior. While standard xanthan gum can thin out in high-ionic-strength formulations (with electrolytes like salts, acids, or certain actives), dehydroxanthan gum maintains viscosity across a broader range of ionic conditions. Provides a cleaner, more elegant texture than conventional gums in lightweight K-beauty formulas.
A starch-derived polysaccharide used to adjust texture and bind ingredients.
Finely milled crystallized carbon (diamond) particles used in luxury cosmetics as a micro-exfoliant and light-reflective texture agent, primarily for optical brightening and physical polishing.
A natural silica mineral formed from fossilized diatom shells, used in cosmetics as an absorbent, mild physical exfoliant, and mattifying agent.
A cationic quaternary ammonium compound derived from coconut fatty acids, used as a skin-conditioning and antistatic agent in cosmetic formulations.
A guanidine salt of succinic acid combined with diglycol. Used as a skin-conditioning and humectant ingredient in skincare formulations. Found in Kanebo's Skin Harmonizer.
A crosslinked silicone elastomer network (distinct from linear dimethicone) that creates a soft, cushiony film on skin and improves the texture and stability of serums, primers, and sunscreens.
A crosslinked copolymer of dimethylacrylamide and sodium acryloyldimethyltaurate used as a salt-tolerant rheology modifier and emulsifier in luxury creams and serums.
The dipotassium salt of phosphoric acid used as a pH-adjusting and buffering agent to maintain the stability and efficacy of cosmetic formulas.
The simplest silicone fluid (hexamethyldisiloxane), a volatile carrier used to improve spreadability and deliver a dry, lightweight skin feel.
A chelating agent that binds metal ions to keep formulas stable.
The disodium salt of guanylic acid (a nucleotide), used in cosmetics as a skin-conditioning and buffering agent.
The disodium salt of inosinic acid (a purine nucleotide), used in cosmetics as a skin-conditioning agent.
The disodium salt of phosphoric acid used as a pH adjuster and buffer to keep cosmetic formulas within their target pH range.
The disodium salt of succinic acid used as a pH-adjusting buffer and mild chelating agent in cosmetic formulas such as toners and essences.
A quaternary ammonium-modified clay (organoclay) used to thicken silicone and oil-based formulas and suspend pigments or mineral UV filters.
A small molecule containing both an amine and a hydroxyl group. Used as a pH adjuster and to neutralize fatty acids (forming soaps) in cosmetic formulations. Considered safe in rinse-off products; use in leave-on products is regulated in EU.
The ethyl ether derivative of cellulose. Functions primarily as a film-former and texture/viscosity modifier in cosmetic formulas. Used in a range of products from foundations to hair care to improve consistency, adherence, and skin feel. Not a functional skin-care active.
A synthetic copolymer of ethylene and methacrylic acid monomers used in cosmetic formulations as a film-forming and texture-modifying agent.
A synthetic hydrocarbon copolymer used primarily in anhydrous cosmetic formulations as a gelling agent and viscosity modifier.
A proprietary blend of extracts from five marine algae: Eucheuma serra (red algae), Grateloupia sparsa (red algae), Saccharina angustata (brown kelp), Ulva linza (sea lettuce, green algae), and Undaria pinnatifida (wakame). Used in Clé de Peau Beauté The Serum for multi-dimensional hydration and skin conditioning.
