Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Cyclopentasiloxane

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

Trimethylsiloxysilicate

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

Ethylhexyl Salicylate

Ethylhexyl salicylate, UVB absorber; volatile, requires combination with UVA filters for broad spectrum.

Isododecane

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

Cetyl PEG/PPG-10/1 Dimethicone

Silicone surfactant, smooth and mild; regulates rheology and adds antistatic benefits

Glycerin

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

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.

Phenyl Trimethicone

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

Dimethicone

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

Magnesium Sulfate

Bulk agent at 0.1–1%; highly water-soluble, avoid high local concentration.

Zinc Stearate

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

Dipropylene Glycol

Solvent for essential oils; better humectancy than PEG

Hydroxyacetophenone

Hydroxyacetophenone as antioxidant; often boosts Vitamin C, works in acidic pH.

Hdi/Trimethylol Hexyllactone Crosspolymer

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

Caprylyl Glycol

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

Tocopheryl Acetate

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

Aluminum

Dimyristate Al

Not decoded yet

Aloe Barbadensis Leaf Extract

Aloe vera leaf extract for soothing and humectant; monitor polysaccharide level and endotoxins

Butylene Glycol

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

Perfluorohexylethyl Triethoxysilane

Not decoded yet

Polyperfluoromethylisopropyl Ether

PFAS (fully-fluorinated) film-former for SPF/lip, <1%; regulatory limits, avoid high-heat, substitute recommended

Trehalose

Trehalose; mild humectant and stabilizer for proteins/actives; hygroscopic, light skin feel.

Urea

Potent humectant and keratolytic, >10% has exfoliating effect; stinging sensation at high levels, sensitive skin caution

Silica

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

1,2-Hexanediol

Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives

Pentylene Glycol

Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin

Serine

Humectant amino acid, 1–3%; high water solubility, compatible with sensitive skin.

Dipotassium Glycyrrhizate

Dipotassium glycyrrhizinate for moisturizing/soothing; inhibits 5-LOX, water-soluble, for sensitive skin.

Xanthan Gum

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

Sodium Hyaluronate

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

Algin

Seaweed-derived thickener at 0.1–1%; provides gel texture, mind calcium ion compatibility

Disodium Phosphate

Phosphate buffer for pH adjustment and preservation; water-soluble; high levels may irritate mucous membranes.

Glyceryl Polyacrylate

Water-soluble film former at 1–5%; light feel, soluble in polyols, non-occlusive

Pullulan

Microbial polysaccharide for film forming and thickening; water-soluble film former used in capsules or moisturizing films.

Potassium Phosphate

pH adjuster for buffering systems; 0.1-1%, avoid calcium and magnesium ions

Glucose

Low-MW humectant and buffer; high hygroscopicity requires careful preservation and humidity control.

Chondrus Crispus Extract

Carrageenan for thickening and moisturizing; seaweed-based, pH-sensitive

Hydroxypropyltrimonium Hyaluronate

Cationic hyaluronic acid, 0.1–1%; water-soluble thickener and conditioning agent.

Hydrolyzed Hyaluronic Acid

Low-MW humectant with superior penetration vs high-MW; 0.1-0.5% typical, hygroscopic, store dry to prevent clumping.

Sodium Acetylated Hyaluronate

Acetylated HA; modified for hydrophobicity, improved penetration and non-tacky feel compared to standard HA.

Hyaluronic Acid

High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.

Hydrolyzed Sodium Hyaluronate

Low-molecular-weight hyaluronic acid derivative with better penetration and strong hydration; different molecular weights provide hydration at various depths, typical concentration 0.1-1%.

Sodium Hyaluronate Crosspolymer

Crosslinked high-MW HA; forms surface hydrogel for long-lasting hydration, minimal penetration, physical film-forming.

Potassium Hyaluronate

Hyaluronic salt, excellent humectant; efficacy varies with MW, best with occlusive base
