Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Ethylhexyl Methoxycinnamate

UVA absorber used with other filters; poor water stability and photolability, requires light stabilizers, max concentration typically 10%.

Butylene Glycol

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

Propylene Glycol

Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.

Butyl Methoxydibenzoylmethane

High-potency UVA filter (Parsol MXX); requires stabilizers and UVB blockers.

Ethylhexyl Salicylate

Ethylhexyl salicylate, UVB absorber; volatile, requires combination with UVA filters for broad spectrum.

Polymethyl Methacrylate

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

Dimethicone

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

2-Ethylhexyl Trans

Not decoded yet

Bisethylhexyloxyphenol Methoxyphenyl Triazine

Chemical UV filter for UVB protection; verify compatibility and stability with other UV filters in the formula.

Silica

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

Polyester-7

Not decoded yet

Glycerin

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

Neopentyl Glycol Diheptanoate

Light emollient ester, non-greasy, improves product spreadability.

C12-15 Alkyl Benzoate

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

Cyclopentasiloxane

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

Titanium Dioxide

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

Polysilicone-11

Not decoded yet

Tocopheryl Acetate

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

Hamamelis Virginiana Bark/Twig Extract

Not decoded yet

Squalane

Emollient from plants or synthetic; light texture

Alumina

Alumina, inorganic abrasive/thickener; nano-grade requires inhalation risk assessment.

Acrylates/C10-30 Alkyl Acrylate Crosspolymer

Crosspolymer for thickening/film; needs neutralization to pH 7-8 to hydrate, check ion strength.

PEG-8

Not decoded yet

Polyhydroxystearic Acid

Emulsifier and stabilizer at 1–3%; non-ionic, prone to hydrolysis.

Hydrogen Dimethicone

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

Hydroxyethylcellulose

Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.

Methylpropanediol

Diol solvent and extraction carrier; enhances solubility of actives, low irritation profile.

Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer

High-molecular-weight thickener and emulsion stabilizer; requires electrolytes or acid adjustment near isoelectric point for optimal performance.

Tocopherol

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

Polygonum Aviculare Extract

Botanical extract used as an emollient. No public irritancy or comedogenic data; monitor for botanical variability.

Niacinamide

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

Sodium Hyaluronate

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

Ascorbyl Palmitate

Ascorbyl palmitate, lipophilic Vit C ester, antioxidant; oxidizes, needs light/air protection.

Polysorbate 60

Non-ionic emulsifier and solubilizer for O/W or W/O stability; may cause mild stinging on sensitive skin, typically 1-5%.

Xanthan Gum

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

Sorbitan Isostearate

Non-ionic emulsifier (low HLB); typically used in blends, low comedogenicity, soft skin feel.

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.

Citric Acid

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

Sodium Hydroxide

Strong base neutralizer for pH adjustment; handle with extreme care

Phenoxyethanol

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

Ethylhexylglycerin

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

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Disodium EDTA

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

Parfum

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