Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Sodium Laureth Sulfate
- Common anionic surfactant, strong foam but drying; check cationic compatibility, high eye irritation
- Cocamidopropyl Betaine
- Cocamidopropyl betaine; zwitterionic co-surfactant reducing irritation and boosting foam, common in mild cleansers.
- Laureth-9
- Not decoded yet
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Sodium Lauroyl Glutamate
- Amino acid surfactant, gentle and suitable for sensitive skin; moderate cleansing power.
- Polyacrylate-1 Crosspolymer
- Not decoded yet
- Fumaric Acid
- Dicarboxylic acid buffer; paired with sodium bicarbonate for pH control, < 0.5%.
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery
- Zinc Pyrithione
- Anti-dandruff active for exfoliation, anti-sebum, and hair conditioning. Restricted in EU to 0.2% in cosmetics. Low irritancy.
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- Parfum
- Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
- Salicylic Acid
- Lipophilic BHA at 0.5-2%; exfoliant/sebum control, irritation/sensitization at high conc., photosensitivity (SPF needed), avoid sensitive/pregnant.
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Sodium Citrate
- Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.
- Allantoin
- Skin soother at 0.5-2%; promotes cell regeneration
- Hydroxypropyl Guar Hydroxypropyltrimonium Chloride
- Cationic guar derivative, conditioner/antistatic; hair/cutaneous use, watch concentration.
- Menthol
- Cooling and soothing agent at 0.5–2%; high levels may cause sensitivity or irritation, use caution around eyes and mucous membranes
- Piroctone Olamine
- Antifungal/antiseborrheic agent; high-concentration irritation; avoid eye area.
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Argilla
- Not decoded yet
- Sodium Polynaphthalenesulfonate
- Sodium polynaphthalenesulfonate; hydrope for dyes and emulsion stabilizer; high levels affect foam.
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Limonene
- Natural fragrance solvent, EU allergen; poor photostability
- Tetrasodium Etidronate
- Chelating agent, stabilizer, restricted use, concentration dependent.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Benzalkonium Chloride
- Cationic preservative/disinfectant. Restricted in EU to 0.1% (0.6% ocular). Irritant; incompatible with anionic surfactants.
- Dmdm Hydantoin
- Formaldehyde-releasing preservative (V/33 limit); monitor cumulative formaldehyde with fragrances.
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Caprylic/Capric Triglyceride
- Light occlusive and solvent at 1–10%; non-greasy feel, suitable for oily and combination skin
- Ascorbic Acid
- Vitamin C, potent antioxidant requiring acidic environment for stability; oxidizes and discolors easily, needs light and air protection, concentration 1-10%, pure L-ascorbic acid is more irritating.
- Ascorbyl Palmitate
- Ascorbyl palmitate, lipophilic Vit C ester, antioxidant; oxidizes, needs light/air protection.
- Ci 47005
- Azo synthetic colorant; comply with EU limit IV/82 and impurity specs.
- Ci 42090
- Acid Blue 9 lake; for coloring and brow tints. Non-permanent hair dye, watch for lake precipitation and batch shade variance.
