Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Methylpropanediol
- Diol solvent and extraction carrier; enhances solubility of actives, low irritation profile.
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Tromethamine
- pH adjuster, alkaline; precise dosing required
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- PEG-60 Hydrogenated Castor Oil
- Non-ionic emulsifier and solubilizer at 1–5%; contains PEG, check acid compatibility and sensitive skin irritation
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Glycyrrhiza Glabra Root Extract
- Liquorice root extract for soothing and brightening; batch variability, watch polyphenol interactions
- Glycine Soja Seed Extract
- Soybean extract for skin conditioning; low allergen risk, monitor batch protein variability.
- PVP
- Polyvinylpyrrolidone for film forming and thickening; used in styling and adhesion, occasional eye irritation reported.
- VP/VA Copolymer
- VA/VP copolymer film former; provides hair fixing; avoid direct contact with eyes or mucous membranes.
- Glycerine
- Workhorse humectant at 3-10%; tacky at high levels, pair with occlusives, low irritancy.
- PEG-10 Dimethicone
- Modified silicone for silky feel and shine; PEG structure aids O/W emulsification, used in hair and skin care.
- Kaolin
- Kaolin absorbent and bulk for powders/masks; check for heavy metals and comply with EU colorant limits IV/119
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Ci 77891
- Titanium dioxide inorganic pigment and UV filter; assess inhalation risk for nano-forms and EU restrictions
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Dipropylene Glycol
- Solvent for essential oils; better humectancy than PEG
- Citrus Nobilis Peel Extract
- Citrus peel extract with fragrance components; astringent, low phototoxicity but caution for sensitive skin
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Melaleuca Alternifolia Leaf Extract
- Tea tree leaf extract for skin conditioning and perfuming; allergen risk requires dilution.
- Glycolic Acid
- Glycolic acid for exfoliation; requires buffering at concentrations >10%, avoid combination with other acids.
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Methylpropanediol
- Diol solvent and extraction carrier; enhances solubility of actives, low irritation profile.
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Centella Asiatica Extract
- Centella asiatica extract for soothing/repair; low irritation, common in sensitive skin products.
- Melissa Officinalis Leaf Extract
- Lemon balm extract for soothing; volatile oils, low allergy risk, light sensitive.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Allantoin
- Skin soother at 0.5-2%; promotes cell regeneration
- Trehalose
- Trehalose; mild humectant and stabilizer for proteins/actives; hygroscopic, light skin feel.
- Alcohol
- Ethanol for solubility/drying at 5-15%; high conc. is drying/irritating, avoid lip/eye, low residue, balance with humectants.
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- PEG-60 Hydrogenated Castor Oil
- Non-ionic emulsifier and solubilizer at 1–5%; contains PEG, check acid compatibility and sensitive skin irritation
- Tromethamine
- pH adjuster, alkaline; precise dosing required
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Ethyl Hexanediol
- Polyol solvent with humectant and mild preservative boost; low viscosity, compatible with many ingredients, gentle.
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
