The pure synthetic acid (INCI: Acetic Acid) used at trace levels as a pH adjuster in cosmetic formulas, distinct from Vinegar (Acetum).
A straight-chain dicarboxylic acid used in cosmetics as a pH buffer and chelating agent. Extremely well-tolerated; appears in mist sprays and lightweight lotions where precise pH control is needed.
An INCI-listed combination ingredient pairing the amino acids alanine and glutamic acid (glutamate), used in Korean prestige formulas as a skin-conditioning agent that contributes to the amino acid profile of the skin's natural moisturizing factor.
The sodium salt of alginic acid extracted from brown seaweed (Phaeophyta spp.). Used as a natural hydrocolloid thickener, film-former, and gel-stabiliser in skincare.
A non-essential amino acid (L-asparagine) used as a skin-conditioning agent in cosmetics, typically as part of amino acid complex formulas that mimic the skin's natural moisturizing factor.
A small molecule with four carboxylic acid groups arranged around a cyclobutane ring. Functions as a chelating agent, binding metal ions that would otherwise catalyze oxidative degradation of active ingredients. Found in Elixir Reflet SPF50+ as a stability enhancer.
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).
The simplest carboxylic acid. In cosmetics, listed at trace levels (typically at the end of amino acid complex formulas) as a pH adjuster. Safe at the very low concentrations used in skincare.
A free-form amino acid (L-glutamine) used in cosmetics as a skin-conditioning agent and component of amino acid complex formulas; distinct from acetyl glutamine which is the N-acetylated form with different stability and activity profile.
A synthetic acrylic copolymer of glyceryl acrylate and acrylic acid used as a film-former and texture agent to enhance moisture retention and skin feel.
A zwitterionic biological buffer (HEPES) used in cosmetics to stabilize formula pH and provide gentle exfoliation by promoting keratinocyte shedding.
A hydroxy fatty acid derived from castor oil used as a gelling and thickening agent in creams and sticks. Contributes minor emollient properties to formulas.
A hydroxy fatty acid derivative. Has mild antimicrobial properties. Used in Kanebo's Skin Harmonizer for conditioning and microbiome-supporting effects.
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.
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 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.
A synthetic monoazo dye (CI 17200) used to give pink or red hues to toners, essences, and rinse-off products. Cosmetic-grade; not approved for use near the eyes in all markets.
A sodium salt copolymer of acrylic acid and maleic acid (MA) used as a polymeric thickener and rheology modifier in cosmetic creams, lotions, and serums.
The sodium salt of glycolic acid. Functions primarily as a pH-buffering and stabilizing agent in cosmetic formulas.
A natural chelating agent derived from rice bran or corn that stabilizes formulas by sequestering trace metals and boosting preservative performance.
The sodium salt of ribonucleic acid (RNA), used as a skin-conditioning agent that improves the feel and suppleness of skin in cosmetic formulations.
