Ingredients explained

Avobenzone

Organic UV filter for UVB and part of UVA-I; poor photostability, used in synergy with other filters.

Octinoxate

Water-soluble UVB absorber for sunscreen; concentration limited by regulations, may irritate sensitive skin

Octocrylene

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

Water

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

Butylene Glycol

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

Dimethicone

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

Dipropylene Glycol

Solvent for essential oils; better humectancy than PEG

Silica

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

Glycerin

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

Polysorbate 60

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

Behenyl Alcohol

Fat alcohol emulsifier/thickener at 1-3%; low comedogenic risk, check solubility in strong acid/base systems, add antioxidants.

Phenoxyethyl Caprylate

Not decoded yet

Sorbitan Stearate

Non-ionic emulsifier for O/W systems; hydrophobic, requires co-emulsifiers, inert at high purity

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

Fragrance

Fragrance; concentration must control allergen risk, label specific components

Chlorphenesin

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

Acrylates/C10-30 Alkyl Acrylate Crosspolymer

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

Potassium Hydroxide

Strong alkali pH adjuster, trace usage (<0.1%); corrosive, must be neutralized.

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Xanthan Gum

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

Sea Water

Natural ingredient with salts; acts as solvent or humectant, high salt content may feel gritty

Palmaria Palmata Extract

Algae extract for barrier protection; concentration supplier-dependent

Trisodium EDTA

Metal chelator improving formula stability and synergizing preservatives; used at very low levels (<0.1%), control heavy metals.

Algae Extract

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

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.

Retinyl Palmitate

Vitamin A ester for skin conditioning; light-sensitive, requires protection, avoid in pregnancy.

Tocopheryl Acetate

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

BHT

Lipophilic antioxidant at 0.01-0.05%; ineffective with acidic systems, label-sensitive, check regulatory limits as preservative alternative.

Barium Sulfate

Inert mineral filler and thickener; not absorbed by skin, avoid dust inhalation in powder processes

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Citric Acid

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

Alumina

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

Mica

Mineral colorant for pearlescence; heavy metal screening required

Ci 77891

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

Iron Oxides

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