Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Glycerol
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives; non-comedogenic
- Alcohol
- Ethanol for solubility/drying at 5-15%; high conc. is drying/irritating, avoid lip/eye, low residue, balance with humectants.
- Glycine
- Humectant amino acid, 1–3%; small molecule, low irritation.
- Tremella Fuciformis Extract
- Tremella extract; rich in polysaccharides, strong humectant that absorbs significant water, low irritation
- vitamin E
- Tocopherol antioxidant; >0.5% may need encapsulation or synergists to prevent oxidation.
- Thermal Spring Water
- Not decoded yet
- Oryza Sativa Lees Extract
- Rice bran extract with lipids and vitamins for skin conditioning; low comedogenicity, suitable for dry or sensitive skin
- EDTA-2Na
- Not decoded yet
- PEG-10 Methyl Ether Dimethicone
- PEG-silicone copolymer for smooth feel and emulsification; improves compatibility.
- PEG-60 Hydrogenated Castor Oil
- Non-ionic emulsifier and solubilizer at 1–5%; contains PEG, check acid compatibility and sensitive skin irritation
- Isotridecyl isononanoate
- Light, dry ester for emulsions; low comedogenicity, suitable for oily/sensitive skin formulas as a light oil alternative.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Sodium Citrate
- Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.
- Di-c12-15 pareth-8 phosphate
- Mild emulsifier and cleansing surfactant; used in creams or washes.
- Diglycerin
- Diglycerin humectant and conditioner; low viscosity suitable for liquid formulas, very low irritancy.
- Diphenylsiloxy Phenyl Trimethicone
- Phenyl trimethicone for anti-foaming and slip; silicone-based, silky feel
- Sorbitan sesquioleate
- Non-ionic emulsifier for O/W or W/O systems; moderate emulsification power, often used with co-emulsifiers
