Ingredients explained

Water

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

Isododecane

Synthetic hydrocarbon solvent providing dry, silky skin feel; high volatility, non-comedogenic, common in sunscreens and foundations, usage 5-30%.

Cyclopentasiloxane

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

Propanediol

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

HDI/Trimethylol Hexyllactone Crosspolymer

Hydrophobic wax for anti-caking; improves slip in powders and cushions

Glycerin

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

Dimethicone

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

Octyldodecyl neopentanoate

Ester emollient; light oil feel; low irrit, low comed, good for fresh systems

Behenyl Alcohol

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

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.

Rosa Multiflora Fruit Extract

Wild rose fruit extract rich in polyphenols; provides antioxidant and aromatic notes; check essential oil allergens

Eriobotrya Japonica Leaf Extract

Loquat leaf extract; rich in flavonoids, high batch-to-batch variability

Stearyl Glycyrrhetinate

Glycyrrhizin derivative offering core soothing and anti-inflammatory benefits, plus emollience for reactive skin

Glycyrrhiza Inflata Root Extract

Glycyrrhiza inflata extract; soothes and anti-irritates. Use at 0.1-1%; monitor glycyrrhizin levels.

Camellia Sinensis Leaf Extract

Green tea extract for antioxidant/astringent; contains caffeine, possible irritation in sensitive skin.

Pistacia Lentiscus Gum

Frankincense resin for film formation and fragrance; natural source, high doses may sensitize

Sericin

Animal-derived silk protein, used for anti-static and hair/skin conditioning; provides smoothness and repair.

Algae Extract

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

Lecithin

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

Inositol

Humectant at 0.5–2%; gentle moisturizing, suitable for sensitive skin

Polyhydroxystearic acid

Emulsifier and stabilizer at 1–3%; non-ionic, prone to hydrolysis.

Sorbitan tristearate

Non-ionic emulsifier for lotions; pairs with water-soluble surfactants.

Sodium Dilauramidoglutamide Lysine

Amino acid-based humectant with moisture-binding properties; low irritancy, improves skin feel and hydration.

Silica

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

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

Beheneth-20

Not decoded yet

Sodium Acrylate/acryloyldimethyltaurate/dimethylacrylamide Crosspolymer

Water-soluble crosspolymer for clear gels/suspension; PEG-free, gentle profile.

Polymethylsilsesquioxane

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

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.

Dimethiconol

Dimethiconol; silicone emollient providing silky feel and reducing friction; moderate comedogenicity, avoid excess.

Disodium EDTA

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

Fragrance

Fragrance; concentration must control allergen risk, label specific components

Ethylhexylglycerin

Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel

Alcohol

Ethanol for solubility/drying at 5-15%; high conc. is drying/irritating, avoid lip/eye, low residue, balance with humectants.

Phenoxyethanol

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

Iron Oxides

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

Tin oxide

Inorganic mineral pigment providing opacity and suspension; requires skin safety assessment, typically used in sunscreens or powder colorants.

Mica

Mineral colorant for pearlescence; heavy metal screening required

Titanium Dioxide

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