Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Propanediol

Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative

Glycerin

Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Betaine

Betaine for mild moisturizing/surfactant; low concentration 1-2% common, high may irritate.

Xanthan Gum

Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration

Potassium Hydroxide

Strong alkali pH adjuster, trace usage (<0.1%); corrosive, must be neutralized.

Phenoxyethanol

Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin

Hydrolyzed Hyaluronic Acid

Low-MW humectant with superior penetration vs high-MW; 0.1-0.5% typical, hygroscopic, store dry to prevent clumping.

Hydrolyzed Sodium Hyaluronate

Low-molecular-weight hyaluronic acid derivative with better penetration and strong hydration; different molecular weights provide hydration at various depths, typical concentration 0.1-1%.

Sodium Hyaluronate

Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture

Sodium PCA

Sodium PCA, NMF component, 1-10% humectant; salty/tacky at high levels.

Caprylyl Glycol

Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol

Ethylhexylglycerin

Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel

Tetrasodium EDTA

Chelator removing metal ions to enhance antioxidant and preservative efficacy; very low usage, typically 0.05-0.1%, no direct skincare function.

Denatonium Benzoate

Industrial denaturant to alter scent and prevent ingestion; not intended for cosmetic use, verify source compliance.

Benzoic Acid

Preservative and pH adjuster at 0.1–0.5%; low water solubility, best in acidic media, irritant at high levels.

Ci 42090

Acid Blue 9 lake; for coloring and brow tints. Non-permanent hair dye, watch for lake precipitation and batch shade variance.
