- Cocamidopropyl Betaine
- Cocamidopropyl betaine; zwitterionic co-surfactant reducing irritation and boosting foam, common in mild cleansers.
- Cocos Nucifera Water
- Coconut water/base; acts as solvent and fragrance component, contains sugars requiring preservatives.
- Volcanic Ash
- Mineral absorbent with porous structure for oil absorption; mild abrasive and bulking, requires particle screening
- Citrus Aurantium Bergamia Fruit Oil
- Bergamot essential oil, natural fragrance and photosensitizer; limit daytime use or use FCF grade
- Hedychium Coronarium Root Extract
- Jasmine root extract; used for fragrance and soothing; essential oil components, monitor allergens
- Charcoal Powder
- Charcoal; adsorbs impurities/oil for cleansers, provides opacity, can be drying or matte.
- Polyquaternium-22
- Not decoded yet
- Linoleamidopropyl Pg-Dimonium Chloride Phosphate
- Linoleic-based cationic conditioner, strong antistatic for dry hair, incompatible with anionic surfactants
- Polyquaternium-39
- Not decoded yet
- Undecane
- Undecane; light aliphatic hydrocarbon emollient; high volatility, pair with occlusives, flammable
- Tridecane
- Tridecane, a long-chain alkane acting as emollient and solvent; petrochemical-derived, inert and low toxicity.
- PEG-150 Pentaerythrityl Tetrastearate
- Mild non-ionic emulsifier; often co-emulsifier for stabilizing O/W or W/O systems, low irritation.
- PPG-2 Hydroxyethyl Cocamide
- Non-ionic surfactant enhancing cleansing and emulsification; coconut-derived, gentle
- Sodium Hydrolyzed Potato Starch Dodecenylsuccinate
- Hydrolyzed potato starch anionic surfactant, biodegradable and mild, suitable for gentle cleansers
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Maltodextrin
- High-MW multifunctional excipient for thickening, binding, and emulsion stability; inert, non-penetrating conditioning.
- Hexylene Glycol
- Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag
- Sodium Citrate
- Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Sodium Benzoate
