Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Dimethicone

Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin

Niacinamide

Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity

Betaine

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

Lauryl PEG/PPG-18/18 Methicone

Not decoded yet

Propanediol

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

Silica

Silica powder at 1–10%; absorbs oil, thickens, provides matte finish, for oil-control products

Dibutyl Adipate

Light ester, solvent and emollient, fresh feel and volatility, non-comedogenic.

Alcohol Denat

Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.

Zinc Pca

Zinc salt for sebum control and antimicrobial; often paired with PCA sodium, high levels may cause sensitization

1,2-Hexanediol

Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives

Pentylene Glycol

Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin

Caprylyl Glycol

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

4-T-Butylcyclohexanol

Fixative and scent masker; not a primary skin conditioning agent.

Sodium Acrylates Crosspolymer-2

Not decoded yet

Polyacrylate Crosspolymer-6

Water-soluble thickener; requires neutralizer, performs best at pH 5–7

Xylitol

Polyol humectant, sweet taste; water-soluble, high hygroscopy, excess draws moisture.

Caprylic Acid

Medium-chain fatty acid with preservative boost and emulsification; distinct odor, irritant at high levels.

Tocopheryl Acetate

Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light

Sphingomonas Ferment Extract

Ferment extract, barrier repair and hydration; 0.1–1% typical, low irritation

Caprylic/Capric Triglyceride

Light occlusive and solvent at 1–10%; non-greasy feel, suitable for oily and combination skin

Glycerin

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

Hydroxyacetophenone

Hydroxyacetophenone as antioxidant; often boosts Vitamin C, works in acidic pH.

Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate

High-efficiency lipid-soluble antioxidant preventing oil rancidity; very low usage, typically 0.05-0.1%, ensure even distribution, avoid metal-catalyzed oxidation.

Parfum

Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.

Maltodextrin

High-MW multifunctional excipient for thickening, binding, and emulsion stability; inert, non-penetrating conditioning.

Bixa Orellana Seed Extract

Annatto seed extract providing natural color and conditioning; may have fragrance notes.

Hydrolyzed Opuntia Ficus-Indica Flower Extract

Hydrolyzed prickly pear flower extract for mild exfoliation and film-forming skin protection; suited for sensitive-skin barrier care.

Disodium EDTA

Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy

Tocopherol

Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light

Retinal

Potent vitamin A aldehyde for cell turnover; low effective range 0.01-0.05%, unstable, avoid for pregnant users.

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Phospholipids

Biomimetic repair and emollient, mimics skin lipids; typically processed at low temps, may be sticky at high levels

T-Butyl Alcohol

Fast-evaporating solvent; sharp odor and potential irritation at high levels, limit usage

Citral

Citral; citrus fragrance component, listed EU allergen, high phototoxicity risk, strict concentration limits apply.

Ascorbic Acid

Vitamin C, potent antioxidant requiring acidic environment for stability; oxidizes and discolors easily, needs light and air protection, concentration 1-10%, pure L-ascorbic acid is more irritating.
