What it is
Caprae Lac is the INCI name for goat milk, incorporated into skincare to provide naturally occurring proteins, fats, vitamins, and lactic acid. These components can help condition and soften the skin and contribute a creamy character to formulas. In sunscreens it is typically used as a conditioning and marketing-forward ingredient rather than as an active.
Safety & warnings
Generally well tolerated. Because it is an animal-derived dairy ingredient, it is not suitable for vegan formulas, and individuals with strong dairy sensitivities may prefer to avoid it. It is not a recognized fragrance allergen.
Origin & sourcing
Natural; the milk obtained from goats (Capra species).
