Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Caprylic/Capric Triglycerides
- Common lightweight ester oil; pleasant skin feel, high biocompatibility for moisturizing bases.
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- Ceteareth-20
- Not decoded yet
- Aluminum Starch Octenylsuccinate
- Modified starch absorbent at 1–10%; for powder products, oil-absorbing without heavy feel
- Lactobacillus/Bulgaricus Ferment Filtrate
- Not decoded yet
- Glyceryl Stearate
- Emulsifier at 1-3%; may require acid to prevent saponification
- PEG-100 Stearate
- Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Hydrogen
- Not decoded yet
- Sodium Polyacrylate Starch
- Sodium polyacrylate starch graft, absorbent and binder; hydrophilic polymer for powders, watch for hardness changes upon hydration.
- Phosphatidylcholine
- Biocompatible emulsifier mimicking sebum; plant/egg derived, check oxidative stability
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Tetrahydrodiferuloylmethane
- Not decoded yet
- Tetrahydrodemethoxydiferuloylmethane
- Not decoded yet
- Tetrahydrobisdemethoxydiferuloylmethane
- Not decoded yet
- Pullulan
- Microbial polysaccharide for film forming and thickening; water-soluble film former used in capsules or moisturizing films.
- Cetyl Alcohol
- Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Dimethyl MEA
- Dimethyl ethylenediamine, weak base buffer; adjusts pH to slightly acidic, strict concentration control
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Sorbic Acid
- Preservative effective at low pH, often combined with sorbate salts; check regulatory limits
