Ingredients explained

Galactomyces ferment filtrate

Galactomyces ferment filtrate humectant; complex matrix, assess allergens and stability.

Butylene Glycol

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

Glycerin

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

Niacinamide

Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity

Pentylene Glycol

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

Phytosteryl/Octyldodecyl Lauroyl Glutamate

Phytosterol blend for skin conditioning; gentle, barrier-repairing, low irritation.

Isopropyl Isostearate

Light emollient/ester for silky feel; stable, O/W compatible, potentially comedogenic at high levels.

Dimethicone

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

Xylitol

Polyol humectant, sweet taste; water-soluble, high hygroscopy, excess draws moisture.

Squalane

Emollient from plants or synthetic; light texture

VINYL DIMETHICONE/METHICONE SILSESQUIOXANE CROSSPOLYMER

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

Boron nitride

Flake-shaped inorganic filler for slip and bulk in powders; control particle size to minimize inhalation risk

Panthenol

Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery

PEG-20 SORBITAN COCOATE

O/W emulsifier and solubilizer in creams and cleansers; coconut fatty-acid ester, screen coconut allergy.

Tocopheryl Acetate

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

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

Acrylates/C10-30 alkyl acrylate crosspolymer

Crosspolymer for thickening/film; needs neutralization to pH 7-8 to hydrate, check ion strength.

Dipentaerythrityl Tri-Polyhydroxystearate

Waxy emollient for feel enhancement; increases viscosity at high levels.

PEG-11 Methyl Ether Dimethicone

Amphoteric emulsifier and conditioner for hair/skin; PEG moiety may concern sensitive skin.

Aminomethyl propanol

pH buffer at 0.1–1%; irritating at high levels, avoid direct mixing with strong acids/bases

Ceratonia Siliqua Fruit Extract

Carob fruit extract, rich in polysaccharides for hydration and film; natural preservative potential requires efficacy verification

Laureth-7

Mild non-ionic surfactant for emulsification and solubilization; biodegradable

Polymethylsilsesquioxane

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

Methylparaben

Preservative, narrow spectrum; often combined, check allergen risk and regulatory limits.

Sodium PEG-7 Olive Oil Carboxylate

Not decoded yet

Xanthan Gum

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

Disodium EDTA

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

PEG-100 Stearate

Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.

PEG-7 Glyceryl Cocoate

PEG-modified nonionic surfactant for emulsification and cleansing; contains PEG, monitor dioxane, low comedogenicity.

Acanthopanax senticosus

Not decoded yet

Benzyl Alcohol

Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.

Ethylhexylglycerin

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

Hydrolyzed soy protein

Hydrolyzed soy protein for hydration and antistatic effect; soy is a common allergen requiring labeling, low comedogenicity.

Cynara Scolymus Leaf Extract

Artichoke leaf extract for skin conditioning; often in botanical blends.

Polyquaternium-7

Not decoded yet

Hydrolyzed Yeast Protein

Hydrolyzed protein for moisture, anti-static, and barrier repair.

Palmitoyl Pentapeptide-4

Signal peptide promoting collagen synthesis; effective at low concentration, needs penetration enhancers or encapsulation

Methylsilanol tri-peg-8 glyceryl cocoate

Not decoded yet

Methicone

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

Titanium Dioxide

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

CI 77492

Iron oxide red; stable inorganic pigment, non-toxic; ensure dispersion to prevent sedimentation.

Water

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