Ingredients explained
- Water/Aqua
- Water as base solvent; no irritation, requires microbial control.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Lactobionic Acid
- Polyhydroxy acid for pH buffering; gentle, check stability at high levels
- Glucono Delta Lactone
- Not decoded yet
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Chondrus Crispus Extract
- Carrageenan for thickening and moisturizing; seaweed-based, pH-sensitive
- Camellia Oleifera Seed Oil
- Camellia seed oil rich in oleic acid and antioxidants for moisturizing; low allergen risk
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
- Glycine Soja Oil
- Soybean oil emollient; prone to oxidation, needs antioxidants; suitable for dry skin
- Dehydroacetic Acid
- Broad-spectrum preservative for acidic and oil-based systems; has concentration limits, requires challenge testing.
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
