Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Hydrogenated Starch Hydrolysate
- Humectant for hydration and film formation; 1-5%, monitor microbial contamination
- Hydrolyzed Rice Protein
- Rice protein; water-soluble small MM; antistatic, humectant, gloss for hair, no pub data
- Aphanizomenon Flos-Aquae Extract
- Not decoded yet
- Hydrolyzed Pea Protein
- Hydrolyzed pea protein; plant-based conditioner/antistatic. Use at 1-3%; requires preservatives.
- Glycoproteins
- Glycoproteins for hydration and conditioning; enhance skin barrier; verify source for vegan requirements.
- Hydrolyzed Glycosaminoglycans
- Hydrolyzed GAGs for hydration/conditioning; low MW, good penetration, low irritancy.
- Hydrolyzed Sodium Hyaluronate
- Low-molecular-weight hyaluronic acid derivative with better penetration and strong hydration; different molecular weights provide hydration at various depths, typical concentration 0.1-1%.
- Glycine
- Humectant amino acid, 1–3%; small molecule, low irritation.
- Proline
- Proline, amino-acid humectant; boosts stratum corneum hydration, stable at pH 4-5.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Copper Gluconate
- Copper gluconate; trace antioxidant/repair agent. Use <0.05%; high levels cause color change/irritation.
- Cellulose
- Plant-derived thickener at 0.1–1%; requires full hydration, poor cationic compatibility
- Hectorite
- Clay absorbent and viscosity controller; used in silicone-free hair products.
- Dehydroacetic Acid
- Broad-spectrum preservative for acidic and oil-based systems; has concentration limits, requires challenge testing.
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Sodium PCA
- Sodium PCA, NMF component, 1-10% humectant; salty/tacky at high levels.
- Parfum
- Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Ci 42090
- Acid Blue 9 lake; for coloring and brow tints. Non-permanent hair dye, watch for lake precipitation and batch shade variance.
