Science

Mechanism of Action

This ingredient primarily functions as an emollient, actively softening and smoothing the skin by improving moisture retention and establishing a protective, non-occlusive barrier that guards against environmental stressors and reduces transepidermal water loss. Its distinctive sensory profile significantly contributes to superior product spreadability and a reduction in tackiness, thereby refining the overall cosmetic texture. Furthermore, it acts as a solvent, efficiently dissolving lipophilic active ingredients like UV filters and aiding in pigment dispersion. In haircare, it serves as a conditioner, coating the cuticle, easing detangling, boosting luster, and minimizing friction and static.

Clinical Evidence

High confidence
Effective range 0.5–20%
Optimal

For achieving optimal skin conditioning and textural benefits in leave-on skincare, concentrations typically range from 1% to 5%, with 2-5% common in creams/lotions and 1-3% in serums.

Key findings

  1. 01 Human patch tests have demonstrated minimal adverse effects, indicating a low allergenic potential and excellent tolerability across skin types.
  2. 02 The Cosmetic Ingredient Review (CIR) expert group has rigorously deemed Isoamyl Laurate safe for cosmetic use, particularly at concentrations up to 2% when formulated to be non-irritating.
