Ingredients explained
Each note carries its evidence level: C comes from official inventories (NMPA names, CosIng functions, annex restrictions); E is AI inference nobody has checked yet — treat it as a candidate. How we grade evidence →
- Aqua
- Solvent, main base; microbial control is criticalE · AI inference · to be verified
- Alcohol Denat
- Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.E · AI inference · to be verified
- PEG-40 Hydrogenated Castor Oil
- Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.B · Third-party verified
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feelC · Official source
- Acrylates Copolymer
- Acrylate synthetic polymer for film forming and antistatic; breathable film, control dosage carefullyB · Third-party verified
- Silanediol Salicylate
- Silicate active, marketed as Pro-Xylane alternative; low MW penetration, avoid excess, high concentration may irritate sensitive skinE · AI inference · to be verified
- Tromethamine
- pH adjuster, alkaline; precise dosing requiredB · Third-party verified
- Caprylic/Capric Triglyceride
- Light occlusive and solvent at 1–10%; non-greasy feel, suitable for oily and combination skinC · Official source
- Hydroxypropyltrimonium Hyaluronate
- Cationic hyaluronic acid, 0.1–1%; water-soluble thickener and conditioning agent.E · AI inference · to be verified
- Triethanolamine
- Triethanolamine for buffering; restricted, limit concentration to avoid high pH and irritationB · Third-party verified
- Biosaccharide Gum-2
- Fermented polysaccharide at 0.5–2%; enhances skin hydration, improves texture, low irritationB · Third-party verified
- Pistacia Lentiscus Gum
- Frankincense resin for film formation and fragrance; natural source, high doses may sensitizeE · AI inference · to be verified
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.B · Third-party verified
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerinC · Official source
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.B · Third-party verified
- Methylparaben
- Preservative, narrow spectrum; often combined, check allergen risk and regulatory limits.B · Third-party verified
