Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Cyclopentasiloxane

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

Butylene Glycol

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

Glycerin

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

Propylene Glycol Dicaprylate/Dicaprate

Lightweight emollient, low viscosity, refreshes skin feel, high compatibility.

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.

C30-45 Alkyl Methicone

C30-45 Alkyl Dimethicone; high-viscosity silicone providing intense occlusion and slip. Used in premium skincare and base makeup.

Cyclohexasiloxane

Volatile cyclic silicone evaporating without residue; ensure compliance with EU limits on cyclic polydimethylsiloxanes, use octamer

C30-45 Olefin

C30-45 Olefin; long-chain hydrocarbon emollient and viscosity modifier. Provides mineral oil-like occlusion with low sensitization risk.

PEG/PPG-18/18 Dimethicone

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

Sodium Citrate

Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.

Polymethylsilsesquioxane

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

Caprylic/Capric Triglyceride

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

Hdi/Trimethylol Hexyllactone Crosspolymer

Hydrophobic wax for anti-caking; improves slip in powders and cushions

Sodium Chloride

Salt for gel viscosity control; used as precipitant in soaps

Dimethicone

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

Phenoxyethanol

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

Tocopherol

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

Parfum

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

Cyclotetrasiloxane

Volatile silicone providing slip; D4 is restricted in EU rinse-off products and requires labeling for leave-on use.

Chlorphenesin

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

Hyaluronic Acid

High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.

Silanetriol

Basic silanetriol for hair anti-static and smoothness; must be complexed with polymers for stability

Methylsilanol Mannuronate

Water-soluble silicone for anti-static and smoothness; chemically stable, no known allergenic data

Stearalkonium Hectorite

Inorganic clay gellant with silky feel; must disperse well, high local dose can irritate.

Glycine Soja Oil

Soybean oil emollient; prone to oxidation, needs antioxidants; suitable for dry skin

Sodium Phytate

Chelating agent stabilizes metal ions to prevent oxidative degradation; also used in oral care, high safety profile.

Disodium Stearoyl Glutamate

Amino acid-based mild cleanser with fine foam; water-soluble.

Propylene Carbonate

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

Sorbitol

Polyol humectant with strong hygroscopy; tacky at high levels, pair with occlusives; also a solvent or adjuster.

Lecithin

Phospholipid emulsifier at 1-5%; biocompatible, moisturizing/antioxidant, prone to oxidation (add TBHQ), mild for sensitive skin.

Xanthan Gum

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

Caprylyl Glycol

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

Alcohol

Ethanol for solubility/drying at 5-15%; high conc. is drying/irritating, avoid lip/eye, low residue, balance with humectants.

Citric Acid

Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH

Sorbic Acid

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

Diatomaceous Earth

Diatomaceous earth for oil absorption/opacification at 1–5%; high surface area, handle dust carefully.

Glyceryl Caprylate

Mild emulsifier/deodorant at 0.5-2%; polyol ester, high humectancy, low irritancy, check cationic surfactant compatibility.

Phenylpropanol

Phenylpropanol for fragrance and solvent; allergen risk, requires assessment

Benzyl Salicylate

UV absorber/light stabilizer, restricted in EU; potential sensitizer, risk assessment needed.

Alpha-Isomethyl Ionone

Vanilla-like fragrance ingredient; one of EU 26 allergens, caution advised for sensitive skin.

Citronellol

Citronellol for fragrance; EU 26 allergen, labeling required above 0.001%.

Limonene

Natural fragrance solvent, EU allergen; poor photostability

Linalool

Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin
