Lavandula Angustifolia (Lavender) Flower Water is the hydrosol (aqueous steam-distillate) collected alongside lavender essential oil production. It contains trace water-soluble fragrant compounds (mainly linalool and its derivatives) but at concentrations far below the essential oil. Used in cosmetics as a mildly soothing, lightly fragranced water base for toners, cleansers, and sensitive-skin formulas. EU allergen regulations apply due to trace linalool content.

An essential branched-chain amino acid used as a humectant that helps maintain skin hydration as part of the skin's natural moisturizing factor.
A filtrate from the fermentation of Leuconostoc bacteria; produces bacteriocins (especially nisin-like compounds) that provide natural antimicrobial activity and support skin microbiome health. Distinct from Leuconostoc/Radish Root Ferment Filtrate.
A natural preservative alternative produced by fermenting radish root with Leuconostoc bacteria, yielding antimicrobial peptides that protect formulas while conditioning skin.
A naturally derived keto-acid used in cosmetics primarily as a mild preservative and pH stabilizer, with additional skin-conditioning properties.
