Ingredients explained

Octinoxate

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

Titanium Dioxide

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

Zinc Oxide

Physical UV filter, 30% max in EU; oily at high levels, pair with oils for feel.

Water\Aqua\Eau

Solvent and diluent; the base for most aqueous formulations.

Methyl Trimethicone

Methyl trimethicone, light volatile silicone; non-comedogenic, good powder compatibility.

Phenyl Trimethicone

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

Silica

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

Butyloctyl Salicylate

Oil-soluble exfoliating emollient; avoid for aspirin-sensitive users and high-concentration leave-on products

Dimethicone

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

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.

Butylene Glycol

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

Dimethicone Silylate

Siloxane; used for defoaming and skin feel; low allergenicity, may clog pores, cautious for oily skin.

Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone

Silicone surfactant at 1–5%; for hair/cleansing, provides smoothness

Ethylhexyl Palmitate

Synthetic ester emollient with light skin feel; small molecule, slightly comedogenic, use cautiously for acne-prone skin, often blended with other oils.

Glycerin

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

Polysilicone-11

Not decoded yet

Citrullus Vulgaris Fruit Extract

Watermelon fruit extract, humectant and conditioner; contains sugars, high levels may invite microbial growth

Sodium Hyaluronate

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

Lecithin

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

Pyrus Malus Fruit Extract

Apple fruit extract, polyphenols for conditioning and antioxidant; batch variation needs standardization

Lens Esculenta Fruit Extract

Lentil extract; protein/sugar; low-conc conditioning, mild, no pub data

Glycine Soja Protein

Soy-based emulsifier and conditioner; improves feel and hair shine, contains allergenic soy protein

Litchi Chinensis Seed Extract

Lychee seed extract with tannins and polyphenols; skin conditioning and antioxidant, water-soluble, check metal interactions.

Laminaria Saccharina Extract

Seaweed-derived hydrating skin protectant rich in polysaccharides; filter to prevent microbial contamination

PEG-10 Dimethicone

Modified silicone for silky feel and shine; PEG structure aids O/W emulsification, used in hair and skin care.

Tocopheryl Acetate

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

Methicone

Volatile silicone offering slip and antistatic properties; inert at high purity, check cyclic isomer limits

Trimethylsiloxysilicate

Silicate powder, oil-absorbing emollient; insoluble, high levels feel powdery.

Sodium PCA

Sodium PCA, NMF component, 1-10% humectant; salty/tacky at high levels.

Sodium Lactate

Sodium lactate for moisturizing and exfoliation; pH buffering agent

Thermus Thermophillus Ferment

Probiotic ferment with humectant properties; use as a low-level skin conditioning agent

Triethyl Citrate

Solvent/plasticizer at 1–10%; provides fresh feel, slight citrus scent

Laureth-7

Mild non-ionic surfactant for emulsification and solubilization; biodegradable

Silica Dimethyl Silylate

Dimethicone modified silica for dry touch; anti-caking and oil absorption

Polymethylsilsesquioxane

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

Magnesium Aluminum Silicate

Oil-absorbing powder at 5–20%; for pressed/powder makeup, high levels may feel heavy

Xanthan Gum

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

Dimethicone/PEG-10/15 Crosspolymer

Silicone/PEG crosspolymer for film forming and viscosity; low irritation; PEG debate at high conc

Sodium Chloride

Salt for gel viscosity control; used as precipitant in soaps

Dextrin

Polymer thickener and binder from starch fermentation; biodegradable, hygroscopic, may affect powder flow

Triethoxycaprylylsilane

Silane coupling agent at 0.1-0.5%; enhances inorganic filler adhesion, trace use, low toxicity, avoid direct contact with aqueous systems.

Disteardimonium Hectorite

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

Caprylyl Glycol

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

Hexylene Glycol

Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag

Polyglutamic Acid

Natural-derived polypeptide for hydration and skin conditioning; often used for long-lasting moisture

Zinc Stearate

Powder slip and dispersing agent for cosmetic powders; insoluble in water/oil.

Disodium EDTA

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

Phenoxyethanol

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

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Sodium Dehydroacetate

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

Mica

Mineral colorant for pearlescence; heavy metal screening required

Titanium Dioxide

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

Iron Oxides

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