A medium-chain polyethylene glycol (~20 ethylene oxide units, ~880 Da) used as a humectant and solvent to hydrate skin and improve formula texture.

A methyl glucose ether modified with 20 ethylene oxide units. Functions as a water-soluble humectant and emollient. Provides a silky skin feel in toners and essences.

A mid-chain polyethylene glycol used as a humectant and solvent in skincare. PEG-30 is water-soluble and helps retain moisture while improving product texture.

A medium-chain polyethylene glycol (MW ~1450 Da) that acts as a humectant, solvent, and consistency agent in lotions and creams. Well-tolerated; used in Japanese toners and emulsions.

A high-molecular-weight polyethylene glycol (~4000 Da) used as a humectant, solvent, and mild thickener in cosmetic and pharmaceutical formulas.

A medium-to-high-chain polyethylene glycol (~45 ethylene oxide units, ~2000 Da) used as a humectant and solvent in skincare formulas.

A medium-chain polyethylene glycol used as a humectant and solvent that helps retain moisture and improve formula texture.

A short-chain polyethylene glycol used as a humectant and solvent to hydrate skin and improve the feel and spreadability of formulas.

A high-molecular-weight polyethylene glycol (~90 ethylene oxide units, ~4000 Da) used as a humectant and mild thickener in skincare formulas.

A triblock glycerin copolymer combining PEG-8, PPG-5, and polybutylene glycol-3 used as a multifunctional humectant to attract and retain moisture in serums and boosters.

A propylene glycol ether of methyl glucose with approximately 10 propylene oxide units. Functions as a humectant in skincare formulations, particularly toners and serums.

A propoxylated methyl glucose ether used as a mild humectant and skin conditioner in toners, essences, and lotions, imparting a smooth, non-greasy hydration.

A polypropylene glycol polymer (17-unit chain) used as a humectant and co-solvent in cosmetics. Lighter and less viscous than glycerin; often combined with it in Japanese toners.

A propylene glycol ether of methyl glucose with approximately 20 propylene oxide units. Used as a humectant and skin-conditioning agent in toners and essences.

A high-propoxylation methyl glucose ether derived from corn glucose and propylene oxide, used as a humectant and mild emollient that provides lasting moisturization without a heavy or tacky feel.

A brown-algae extract used to support hydration and a plumped, conditioned feel.

An extract from Pelvetia canaliculata (channelled wrack), a brown marine alga containing fucoidans, alginates, and polyphenols that provide humectant, antioxidant, and skin-conditioning benefits.

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

Extract from Phormium tenax (New Zealand flax / harakeke), a monocot in the Xanthorrhoeaceae family unrelated to common flax (Linum usitatissimum), with traditional Māori use in wound and skin care. Primary bioactive fractions are polysaccharides rich in D-xylose and D-glucuronic acid alongside linoleic acid, which contributes to ceramide biosynthesis and barrier integrity. The hero ingredient in The Saem Urban Eco Harakeke product line.

The fresh sap (juice) pressed from Phyllostachys bambusoides (Moso bamboo), used as a silica-rich, lightweight humectant and skin conditioner in Korean skincare formulations.

A glucoside-modified poly(2-hydroxyethyl methacrylate) polymer used as a hydrating film-former. Its sugar side-chains bind water effectively, providing prolonged moisturisation in toners and essences.

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 trimer of glycerin used as a humectant and skin-conditioning agent that hydrates and improves the feel of cosmetic formulas.
