Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Glycolic Acid
- Glycolic acid for exfoliation; requires buffering at concentrations >10%, avoid combination with other acids.
- Arginine
- Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Stearic Acid
- Fatty acid emulsifier, white waxy solid; adds slip feel
- Ammonium Hydroxide
- Strong alkaline pH adjuster; use in low concentrations to neutralize acids, avoid direct mixing with strong acids.
- Isostearic Acid
- Fatty acid derivative as emulsifier auxiliary and emollient; insoluble, requires homogenization, may feel slightly greasy
- PEG-100 Stearate
- Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.
- Lactobionic Acid
- Polyhydroxy acid for pH buffering; gentle, check stability at high levels
- Isododecane
- Synthetic hydrocarbon solvent providing dry, silky skin feel; high volatility, non-comedogenic, common in sunscreens and foundations, usage 5-30%.
- Isohexadecane
- Lightweight mineral-oil-derived emollient and solvent; low viscosity, non-comedogenic, improves texture
- Glyceryl Stearate
- Emulsifier at 1-3%; may require acid to prevent saponification
- Cetyl Alcohol
- Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.
- Sorbitan Stearate
- Non-ionic emulsifier for O/W systems; hydrophobic, requires co-emulsifiers, inert at high purity
- Methylglucamine
- Methylglucamine, cationic humectant and conditioner; pH adjuster, tacky at high levels
- Magnesium Aluminum Silicate
- Oil-absorbing powder at 5–20%; for pressed/powder makeup, high levels may feel heavy
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- 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
- Bisabolol
- Soothing and anti-inflammatory agent, 0.01–0.1%; low irritation, good for sensitive skin.
- BHT
- Lipophilic antioxidant at 0.01-0.05%; ineffective with acidic systems, label-sensitive, check regulatory limits as preservative alternative.
- Propylparaben
- Medium-chain preservative; restricted use, pH-sensitive efficacy.
- Methylparaben
- Preservative, narrow spectrum; often combined, check allergen risk and regulatory limits.
