About LACTIS PROTEINUM
Latin INCI for "milk protein" — a mixture of casein and whey proteins. Gentle and conditioning, but a milk allergen for sensitive users.
Detailed Analysis
Lactis proteinum is the INCI (Latin) name for milk protein, comprising primarily casein (≈80%) and whey proteins (β-lactoglobulin, α-lactalbumin). It is used in skincare for soothing and mild film-forming effects and in hair care for conditioning. Milk proteins, especially β-lactoglobulin, are recognised allergens with documented cases of cosmetic-triggered reactions in cow-milk-allergic individuals. CIR has reviewed milk-derived ingredients without major issue beyond the allergen flag. Non-vegan.
