Ingredients explained
- Water/Aqua/Eau
- Primary aqueous solvent and carrier; no specific incompatibilities, focus on microbial stability.
- Sodium Laureth Sulfate
- Common anionic surfactant, strong foam but drying; check cationic compatibility, high eye irritation
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Glycolic Acid
- Glycolic acid for exfoliation; requires buffering at concentrations >10%, avoid combination with other acids.
- Cocamidopropyl Betaine
- Cocamidopropyl betaine; zwitterionic co-surfactant reducing irritation and boosting foam, common in mild cleansers.
- Lauryl Glucoside
- Mild nonionic surfactant for cleansing; 1-5%, suitable for sensitive skin
- Allantoin
- Skin soother at 0.5-2%; promotes cell regeneration
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery
- Arginine
- Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.
- Peg-6 Caprylic/Capric Glycerides
- Mild nonionic emulsifier for O/W or W/O; contains PEG, verify preservative system.
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- Peg-150 Pentaerythrityl Tetrastearate
- Mild non-ionic emulsifier; often co-emulsifier for stabilizing O/W or W/O systems, low irritation.
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
