Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Pentylene Glycol
- Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Peg-8
- Not decoded yet
- Saccharide Isomerate
- Novel polyol humectant with skin feel improvement; high hydration, suitable for lightweight formulas.
- Ammonium Acryloyldimethyltaurate/Beheneth-25 Methacrylate Crosspolymer
- Strong anionic emulsifier for O/W emulsions; incompatible with cationic surfactants
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Peg-40
- Not decoded yet
- Hydrogenated Castor Oil
- Hydrogenated castor oil for emollient, emulsifying, mild cleansing; ensure high purity
- Trideceth-9
- Not decoded yet
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Polyvinyl Alcohol
- Film/viscosity agent for masks/cleansers; water-soluble, forms flexible film
- Bht
- Lipophilic antioxidant at 0.01-0.05%; ineffective with acidic systems, label-sensitive, check regulatory limits as preservative alternative.
- Benzophenone-4
- Not decoded yet
- Glyceryl Acrylate/Acrylic Acid Copolymer
- Acrylate copolymer for thickening and moisturizing; synthetic polymer with low sensitization risk.
- Pvm/Ma Copolymer
- Film former at 1–5%; for styling/hair care, provides lasting effect
- Potassium Chloride
- Viscosity modifier for gels and shampoos; high concentrations may cause local stinging.
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- 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.
- Sodium Lactate
- Sodium lactate for moisturizing and exfoliation; pH buffering agent
- T-Butyl Alcohol
- Fast-evaporating solvent; sharp odor and potential irritation at high levels, limit usage
- Lactic Acid
- AHA pH adjuster at 0.5-5%; exfoliation/humectancy, mild at low conc., irritating at high, avoid conflict with alkaline preservatives.
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
