Ingredients explained
- Deionized Water
- Deionized water as primary solvent; inactive but carries other ingredients, purity needed to prevent metal ion interference.
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Bis-PEG-18 Methyl Ether Dimethyl Silane
- Silicone modifier for smoothness; contains PEG, used for foam and cleansing, manage PEG residuals
- Sodium PCA
- Sodium PCA, NMF component, 1-10% humectant; salty/tacky at high levels.
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery
- Saccharide Isomerate
- Novel polyol humectant with skin feel improvement; high hydration, suitable for lightweight formulas.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Betaine
- Betaine for mild moisturizing/surfactant; low concentration 1-2% common, high may irritate.
- Allantoin
- Skin soother at 0.5-2%; promotes cell regeneration
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Hydroxyethyl Urea
- Potent humectant and conditioner; high penetration, used for skin hydration and hair care
- Zinc Pca
- Zinc salt for sebum control and antimicrobial; often paired with PCA sodium, high levels may cause sensitization
- 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.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Polyacrylate Crosspolymer-6
- Water-soluble thickener; requires neutralizer, performs best at pH 5–7
- Hydroxyethyl Acrylate
- Acrylate monomer, used as copolymer; monomer is a sensitizer, low residual
- Sodium Acryloyldimethyl Taurate Copolymer
- Water-soluble cationic polymer for conditioning, suspension, and film; often paired with cationic surfactants, pH sensitive
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
