Key Benefits & Product Applications
- Long-lasting cooling (8+ hours) – Enzymes in the skin slowly hydrolyze Menthyl Lactate, releasing PCA (a key component of the skin’s Natural Moisturizing Factor). This provides a sustained cooling sensation lasting over 8 hours, along with moisturizing, soothing, and anti-inflammatory benefits.
- Gentle & non-irritating – Menthyl Lactate is mild, virtually odorless, and does not cause skin irritation, making it suitable for sensitive skin and leave-on products.
- Natural moisturizing effect – Helps maintain skin hydration through its humectant properties.
- Excellent fragrance compatibility – Works synergistically with fragrances, making it easy to formulate into a wide variety of products.
- Broad applications – Suitable for all-day freshness products, shampoos, body washes, perfumes, colognes, skin moisturizers, and more.
