Ingredients explained

Isododecane

Synthetic hydrocarbon solvent providing dry, silky skin feel; high volatility, non-comedogenic, common in sunscreens and foundations, usage 5-30%.

Dimethicone

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

Phenyl Trimethicone

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

Butylene Glycol

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

Cetyl PEG/PPG-10/1 dimethicone

Silicone surfactant, smooth and mild; regulates rheology and adds antistatic benefits

C12-15 alkyl benzoate

C12-15 alkyl benzoate; emollient, emulsifier, and antistatic; aids stability and smoothness, moderate low comedogenicity.

VINYL DIMETHICONE/METHICONE SILSESQUIOXANE CROSSPOLYMER

Rheology-modifying silicone polymer for suspension and feel; requires silicone-compatible system

Cyclopentasiloxane

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

Polyglyceryl-4 isostearate

Emulsifier at 1–5%; mild type, suitable for sensitive skin formulas

Polymethylsilsesquioxane

Silicone polymer for emolliency, matte effect, and suspension; used in foundations or powder suspensions, typical usage 1-5%, smooth skin feel.

Sodium chloride

Salt for gel viscosity control; used as precipitant in soaps

Talc

Inorganic mineral powder for texture and oil absorption; must be asbestos-free; fineness affects skin feel and safety, avoid inhalation.

Phenoxyethanol

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

Disteardimonium Hectorite

Inorganic ionic clay thickener at 0.25-1%; water/oil/solvent systems, rheology control, avoid strong acids, may affect active release.

Boron nitride

Flake-shaped inorganic filler for slip and bulk in powders; control particle size to minimize inhalation risk

Sodium Dehydroacetate

Sodium dehydroacetate, preservative <0.5%; restricted for eye, children, and lip use.

Propylene carbonate

Inert solvent and viscosity modifier; often used as penetration enhancer, mild at low levels

Xanthan Gum

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

Aluminum hydroxide

Aluminum hydroxide for emollient/thickening; opacifier, used in antiperspirants, particulate risk.

Polymethyl Methacrylate

PMMA for thickening, suspension, and film; micro-size powder carrier, very low irritation

Hydrogen Dimethicone

Hydrogenated dimethicone for film-forming and slip; low volatility, rich feel for dry skin

Dimethicone/Vinyl Dimethicone Crosspolymer

Crosslinked silicone thickener at 0.5-2%; silky/matte feel, non-comedogenic, partial oil phase incompatibility, use co-solvent/pre-emulsification.

Tetrasodium EDTA

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

Mica

Mineral colorant for pearlescence; heavy metal screening required

Ethylhexylglycerin

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

Tocopheryl Acetate

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

Glycerin

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

PEG-8 Methyl Ether Dimethicone

Not decoded yet

Perfluorodecalin

Perfluorodecalin, hydrophobic solvent and glossing agent; used in haircare or dry shampoo, insoluble in water, control usage to avoid greasiness

Glycosphingolipids

Lipids mimicking sebum to repair skin barrier and reduce TEWL. Biological origin, low irritancy.

Simmondsia Chinensis Seed Extract

Not decoded yet

Yeast Extract

Yeast extract for skin care and protection; common, low allergy risk

Sucrose palmitate

Succrose ester for gentle emulsification/cleansing; biodegradable, low comedogenicity.

1,2-Hexanediol

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

Caprylyl Glycol

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

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

CI 77891

Titanium dioxide inorganic pigment and UV filter; assess inhalation risk for nano-forms and EU restrictions

Iron Oxides (CI 77491

Not decoded yet

CI 77492

Iron oxide red; stable inorganic pigment, non-toxic; ensure dispersion to prevent sedimentation.
