Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Glycereth-26
- Glycereth-26, humectant/viscosity modifier at 1–5%; non-ionic water-soluble, boosts stability and feel.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Sodium Polyacrylate
- Superabsorbent resin, <1%; gels with electrolytes, ionic strength control required.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Aloe Barbadensis Leaf Juice
- Natural humectant and soother with high water activity; requires preservative system, generally well-tolerated
- Hydrolyzed Collagen
- Hydrolyzed protein for film-forming and moisture; molecular weight limits penetration, check source for shellfish allergies
- Soluble Collagen
- Water-soluble collagen for hydration, film-forming, hair care; MW affects permeation/film
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- PPG-26-Buteth-26
- Not decoded yet
- Palmaria Palmata Extract
- Algae extract for barrier protection; concentration supplier-dependent
- PEG-40 Hydrogenated Castor Oil
- Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.
- Parfum
- Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
- Chlorphenesin
- Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Hydrolyzed Soybean Extract
- Not decoded yet
- Biosaccharide Gum-1
- Biosaccharide Gum-1, fermented colloid for hydration and soothing, low comedogenic.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Benzoic Acid
- Preservative and pH adjuster at 0.1–0.5%; low water solubility, best in acidic media, irritant at high levels.
- Sorbic Acid
- Preservative effective at low pH, often combined with sorbate salts; check regulatory limits
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Benzyl Salicylate
- UV absorber/light stabilizer, restricted in EU; potential sensitizer, risk assessment needed.
- Alpha-Isomethyl Ionone
- Vanilla-like fragrance ingredient; one of EU 26 allergens, caution advised for sensitive skin.
- Citronellol
- Citronellol for fragrance; EU 26 allergen, labeling required above 0.001%.
- Eugenol
- Potent natural fragrance, EU restriction III/71; listed allergen, max 5%, caution for sensitive skin
