Ingredients explained

Cyclopentasiloxane

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

Dimethicone

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

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.

Hydrogenated Vegetable Oil

Occlusive emollient for smooth feel; high levels may be comedogenic, use caution for acne-prone skin

Pentaerythrityl Tetraisostearate

Mild emulsifier and emollient with cleansing function; suitable for baby and sensitive skin, low irritancy.

Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer

Rheology-modifying silicone polymer for suspension and feel; requires silicone-compatible system

Mica

Mineral colorant for pearlescence; heavy metal screening required

Disteardimonium Hectorite

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

PEG-10 Dimethicone

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

PPG-25-Laureth-25

Not decoded yet

Silica Dimethyl Silylate

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

Silica

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

Water/Aqua/Eau

Primary aqueous solvent and carrier; no specific incompatibilities, focus on microbial stability.

Tocopheryl Acetate

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

Parfum/Fragrance

Blended fragrance for odor; contains 26 restricted allergens, use caution in sensitive/child/eye products, verify compliance.

Trimethylsiloxysilicate

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

Diethylhexyl Syringylidenemalonate

New UV filter (UVA/UVB); EU limits 2.8%/1.4%, potential sensitizer, stability required

Ascorbyl Palmitate

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

Propylene Glycol

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

Caprylic/Capric Triglyceride

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

Sodium Cocoyl Alaninate

Amino acid-based surfactant for gentle cleansing and hair conditioning.

Butylene Glycol

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

Glyceryl Stearate

Emulsifier at 1-3%; may require acid to prevent saponification

Citric Acid

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

Hydrolyzed Collagen

Hydrolyzed protein for film-forming and moisture; molecular weight limits penetration, check source for shellfish allergies

Triethoxycaprylylsilane

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

Hydrolyzed Elastin

Hydrolyzed elastin, moisturizer; MW determines penetration, large MW surface conditioning.

Cetyl Hydroxyethylcellulose

Water-soluble cellulose derivative; viscosity booster and emulsion stabilizer; pH sensitive.

Rutin

Flavonoid antioxidant; also conditions skin, note stability in aqueous solutions.

Palmitoyl Tetrapeptide-7

Palmitoyl Tetrapeptide-7 boosts collagen; use 0.1–1%, formulate with lipid carriers

Palmitoyl Tripeptide-1

Palmitoyl Tripeptide-1 for repair; requires lipid carrier, unstable in aqueous phase

Phaseolus Lunatus Seed Extract

White kidney bean extract, often for alpha-amylase inhibition. In skincare: skin conditioner/emollient.

Phenoxyethanol

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

Limonene

Natural fragrance solvent, EU allergen; poor photostability

Linalool

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

Citral

Citral; citrus fragrance component, listed EU allergen, high phototoxicity risk, strict concentration limits apply.

Hexyl Cinnamal

Common fragrance component (jasmine/vanilla note); listed EU allergen, requires labeling at >10ppm (leave-on).

Hydroxycitronellal

Hydroxycitronellal, sensitizing fragrance, EU limit <0.1%; avoid use as aerosol propellant.

Titanium Dioxide

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

Carmine

Natural red colorant (cochineal); may trigger reactions in those with insect protein allergy
