Caprae Lac

Caprae Lac (goat milk) is used as a skin-conditioning/emollient ingredient and may contain lactose, milk proteins, and naturally occurring organic acids that can be mildly irritating, especially on compromised barriers. While many users tolerate it at typical cosmetic levels, animal-derived milk components can trigger stinging or eczematous flares in reactive or atopic individuals (irritant and, less commonly, allergy-mediated), so I rate it as mild rather than “gentle” for sensitive-skin safety. Safety Notes: Caprae Lac (goat milk) is used in consumer skincare either as a minor “milk extract”/powdered additive at trace-to-low levels (~0.01–1%) in leave-on creams/serums and many rinse-off cleansers, or as a primary marketing-active in goat-milk soaps, masks, and lotions where the milk (fresh, reconstituted powder, or concentrated milk fractions) can be a major phase component. In real-world OTC products, high-strength bar soaps and some lotions commonly reach ~5–20% and a small number of specialty ‘goat milk’ formulations list milk high in the composition, supporting upper-end use around ~30% (higher is uncommon due to odor, microbial load/preservation demand, and stability/processing constraints).
