Ingredients explained

Cyclopentasiloxane

Cyclopentasiloxane for emollient/solvent; volatile silicone, smooth feel, check VOC regulations.

Water

Primary solvent and base; requires preservative system to prevent microbial growth

Trimethylsiloxysilicate

Silicate powder, oil-absorbing emollient; insoluble, high levels feel powdery.

Butylene Glycol

Polyol humectant and solvent at 1–5%; aids solubilization, light feel

PEG/PPG-18/18 dimethicone

PEG/PPG siloxane; emulsifier/thickener; low irrit, watch PEG total conc limits

Sorbitan sesquioleate

Non-ionic emulsifier for O/W or W/O systems; moderate emulsification power, often used with co-emulsifiers

Tribehenin

Waxy emollient providing slip; prone to oxidation, needs antioxidant system; good for dry skin.

Magnesium sulfate

Bulk agent at 0.1–1%; highly water-soluble, avoid high local concentration.

Phenyl Trimethicone

Aromatic modified silicone for high gloss and occlusion; inert, non-volatile, may leave surface residue

Dimethicone Crosspolymer

Crosslinked silicone polymer providing silkiness and viscosity control; for hair and skin; inert but hard to biodegrade.

Dimethicone

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

Methicone

Volatile silicone offering slip and antistatic properties; inert at high purity, check cyclic isomer limits

Silica

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

Nylon-12

Not decoded yet

Olea Europaea Leaf Extract

Olive leaf extract with hydroxytyrosol; antioxidant and polyphenolic; mild fragrance and skin conditioning.

Algae Extract

Algae extract with humectant and conditioning effects; may contain natural fragrant components.

Oryza Sativa Bran Extract

Rice bran extract rich in vitamins; moisturizing and soothing, generally well-tolerated.

Glycerin

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

Ethylhexylglycerin

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

Laureth-7

Mild non-ionic surfactant for emulsification and solubilization; biodegradable

Xanthan Gum

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

Tocopheryl Acetate

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

Sodium Hyaluronate

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

Tocopherol

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

Caprylyl Glycol

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

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.

Phenoxyethanol

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

Chlorphenesin

Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.

Sorbic Acid

Preservative effective at low pH, often combined with sorbate salts; check regulatory limits

Titanium Dioxide

Physical UV filter and colorant up to 25%; nano form requires attention

Iron Oxides

Inorganic pigment for color; particulate form, inhalation risk low in cosmetics.
