Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Alcohol Denat
- Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.
- PEG-40 Hydrogenated Castor Oil
- Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Acrylates Copolymer
- Acrylate synthetic polymer for film forming and antistatic; breathable film, control dosage carefully
- Silanediol Salicylate
- Not decoded yet
- Tromethamine
- pH adjuster, alkaline; precise dosing required
- Caprylic/Capric Triglyceride
- Light occlusive and solvent at 1–10%; non-greasy feel, suitable for oily and combination skin
- Hydroxypropyltrimonium Hyaluronate
- Cationic hyaluronic acid, 0.1–1%; water-soluble thickener and conditioning agent.
- Triethanolamine
- Triethanolamine for buffering; restricted, limit concentration to avoid high pH and irritation
- Biosaccharide Gum-2
- Not decoded yet
- Pistacia Lentiscus Gum
- Frankincense resin for film formation and fragrance; natural source, high doses may sensitize
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
- Methylparaben
- Preservative, narrow spectrum; often combined, check allergen risk and regulatory limits.
