Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Alcohol Denat
- Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- Butyrospermum Parkii Butter
- Shea butter for occlusive moisturizing; high melt point, rich texture, caution for oily skin.
- Rhus Verniciflua Peel Cera
- Not decoded yet
- Ricinus Communis Seed Oil
- Castor oil for heavy moisturization and film formation; high viscosity, high levels may be comedogenic, blend with other oils.
- Sodium Cetearyl Sulfate
- Anionic surfactant with strong foaming and cleansing power; milder than SLS but can still irritate dry skin.
- Hydrogenated Jojoba Oil
- Hydrogenated jojoba oil, emollient; lower comedogenicity than native oil
- Simmondsia Chinensis Seed Oil
- Common in dry/damaged hair; superior penetration vs mineral oils, low comedogenic risk, poor oxidative stability.
- Prunus Amygdalus Dulcis Oil
- Sweet almond oil, light emollient; suitable for sensitive skin, caution for nut allergies.
- Dehydroxanthan Gum
- Modified polymer for emulsion stability and film forming; high viscosity impact.
- Hydrolyzed Corn Protein
- Hydrolysed corn protein conditioner at 1–10%; small peptides, prone to browning, chelators recommended
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Helianthus Annuus Seed Oil
- Sunflower seed oil for emollient/occlusive; high linoleic acid, low comedogenicity.
- Hydrolyzed Wheat Protein
- Hydrolyzed protein for hair and skin conditioning; potential allergen, use low levels in sensitive products
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Hydrolyzed Soy Protein
- Hydrolyzed soy protein for hydration and antistatic effect; soy is a common allergen requiring labeling, low comedogenicity.
- Sodium Sulfate
- Inorganic salt for viscosity; high concentrations cause osmotic dehydration.
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- Leuconostoc/Radish Root Ferment Filtrate
- Bio-fermented filtrate for antimicrobial and anti-dandruff effects; assess individual variability, avoid in known allergy.
- Parfum
- Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
- Limonene
- Natural fragrance solvent, EU allergen; poor photostability
- Linalool
- Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin
- Geraniol
- Geraniol for fragrance; EU 26 allergen, labeling required above 0.001%.
- Citral
- Citral; citrus fragrance component, listed EU allergen, high phototoxicity risk, strict concentration limits apply.
- Citronellol
- Citronellol for fragrance; EU 26 allergen, labeling required above 0.001%.
