Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Betaine
- Betaine for mild moisturizing/surfactant; low concentration 1-2% common, high may irritate.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Ethoxydiglycol
- Ethoxydiglycol; high-perf solv/humectant; low irrit, EU limit 20%, watch total PEG load
- Isopentyldiol
- Solvent at 1–10%; helps dissolve actives, fresh feel
- Methylpropanediol
- Diol solvent and extraction carrier; enhances solubility of actives, low irritation profile.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Hyaluronic Acid
- High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.
- Jania Rubens Extract
- Jania rubens extract with polysaccharides; moisturizing skin conditioner, check algal batch stability.
- Silanetriol
- Basic silanetriol for hair anti-static and smoothness; must be complexed with polymers for stability
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Dehydroacetic Acid
- Broad-spectrum preservative for acidic and oil-based systems; has concentration limits, requires challenge testing.
- Phenethyl Alcohol
- Alcohol with preservative and fragrance properties; 0.5-1%, floral scent, can replace some preservatives
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Polyquaternium-51
- Not decoded yet
- Sodium Carrageenan
- Seaweed-derived thickener and stabilizer, 0.5-1.5% adjusts viscosity; sensitive to ions, test compatibility with cationic surfactants.
- Chlorphenesin
- Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
