Ingredients explained
- Ethylhexyl Palmitate
- Synthetic ester emollient with light skin feel; small molecule, slightly comedogenic, use cautiously for acne-prone skin, often blended with other oils.
- Synthetic Wax
- Waxy solidifier for hardness and gloss; complex mixture, not a single molecule.
- Isohexadecane
- Lightweight mineral-oil-derived emollient and solvent; low viscosity, non-comedogenic, improves texture
- Kaolin
- Kaolin absorbent and bulk for powders/masks; check for heavy metals and comply with EU colorant limits IV/119
- Mica
- Mineral colorant for pearlescence; heavy metal screening required
- Isopropyl Myristate
- Light synthetic ester, fast-drying and non-greasy; high comedogenic risk, limit in acne-prone skin
- Cera Microcristallina
- Mineral-derived microcrystalline wax, potent occlusive moisturizer; 1-3% significantly extends hydration, heavy texture.
- Hydrogenated Styrene/Isoprene Copolymer
- Hydrogenated styrene/isoprene copolymer for viscosity control; film-forming polymer, generally inert and non-comedogenic.
- Cyclopentasiloxane
- Cyclopentasiloxane for emollient/solvent; volatile silicone, smooth feel, check VOC regulations.
- 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.
- 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
- PEG-8
- Not decoded yet
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Ascorbyl Palmitate
- Ascorbyl palmitate, lipophilic Vit C ester, antioxidant; oxidizes, needs light/air protection.
- 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
- Ci 77891
- Titanium dioxide inorganic pigment and UV filter; assess inhalation risk for nano-forms and EU restrictions
- Ci 77491
- Iron oxides red; physical pigment. Coloring and photo-protective, stable and non-irritating.
- Ci 77492
- Iron oxide red; stable inorganic pigment, non-toxic; ensure dispersion to prevent sedimentation.
- Ci 77499
- Inorganic colorant manganese dioxide used in cosmetics; restricted use component subject to regulatory limits.
- Ci 16035
- Azo hair dye component, requires alkaline activation. Restricted to professional hair use, not for daily wash.
- Ci 19140
- Acid Yellow 23 lake; for coloring and hair dyeing. High water solubility and precipitation risk, pH control required.
- Ci 15850
- Synthetic dye, red 57; restricted to hair dyeing in EU, not for topical cosmetics.
- Ci 45410
- Acid Red 9, a dye used in hair coloring; restricted to rinse-off hair dye with strict residue limits.
- Ci 45380
- Azo dye, restricted in EU; limited to hair dyes, sensitizing risk, strict compliance required
- Ci 15850
- Synthetic dye, red 57; restricted to hair dyeing in EU, not for topical cosmetics.
- Ci 42090
- Acid Blue 9 lake; for coloring and brow tints. Non-permanent hair dye, watch for lake precipitation and batch shade variance.
