Góc nhìn công thức Lightweight sunscreen with alcohol for penetration and fast-drying. Multiple organic filters including avobenzone and Tinosorb S. Humectants include glycerin and light esters. Factory note: high alcohol volatility changes viscosity post-drying; balancing volatiles with residue is key to preventing clumping.

Tóm tắt nhanh

Giải thích thành phần

Aqua/Water

Solvent, formulation base; requires preservation, pure water is microbially prone.

Alcohol Denat

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

Homosalate

UVB sunscreen agent, often combined with others; stable but migratory; ensure regulatory compliance.

Ethylhexyl Salicylate

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

Butyl Methoxydibenzoylmethane

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

Ethylhexyl Triazone

UVB absorber with good photostability; formulated with other filters, typical concentration 3-5%, check compatibility with other ingredients.

Octocrylene

UV-B absorber and photostabilizer; has concentration limits, consider potential coral toxicity and allergenicity for specific groups.

Glycerin

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

Propanediol

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

Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine

UV-B absorber, photostable; high purity and low bioaccumulation, check for impurities.

C12-22 Alkyl Acrylate/Hydroxyethylacrylate Copolymer

Acrylate copolymer for thickening and stability; non-irritating

Diisopropyl Adipate

Diisopropyl adipate for emollience and plasticizing; lipophilic, potential comedogenic

Diisopropyl Sebacate

Low-viscosity, high-flash-point ester; excellent spreadability, non-greasy feel

Dicaprylyl Ether

Lightweight diester solvent and emollient, non-greasy feel; common oil phase carrier; low irritation.

Triethanolamine

Triethanolamine for buffering; restricted, limit concentration to avoid high pH and irritation

Tocopherol

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

Phenylbenzimidazole Sulfonic Acid

UV absorber and light stabilizer; compliant use required, common in sunscreens

Acrylates/C10-30 Alkyl Acrylate Crosspolymer

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

Caprylyl Glycol

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

Drometrizole Trisiloxane

UVB sunscreens agent; limited by EU, must be used within strict limits.

Sodium Polyacrylate

Superabsorbent resin, <1%; gels with electrolytes, ionic strength control required.

Trisodium Ethylenediamine Disuccinate

Mild chelator replacing EDTA; water-soluble, very low irritation, stabilizes metal ions

Parfume

Fragrance blend to mask odor; may contain 26 EU allergens, proceed with caution in sensitive skin.
