PPG-2 MYRISTYL ETHER PROPIONATE.

Valuable CAS 74775-06-7 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

PPG-2 Myristyl Ether Propionate is a versatile liquid emollient and sensory modifier, engineered to enhance the aesthetic feel of skincare formulations. It provides a soft, smooth skin finish without residual greasiness, while simultaneously improving the spreadability and efficacy of oil-soluble active ingredients.

Science

Mechanism of Action

This ingredient functions primarily as a liquid emollient, effectively filling microscopic gaps between dried skin cells to create a noticeably smoother skin surface. It forms a subtle film that reinforces the skin barrier, assisting in moisture retention and protection. As a solvent and co-solvent, it excels at uniformly distributing lipophilic actives, such as UV filters and fragrances, improving their performance and reducing product tack. Furthermore, its surfactant and emulsifying properties contribute to the stability of formulations and ensure a consistent, elegant application.

Key findings

  1. 01 Recommended at 1-5% for general applications as a liquid emollient, emulsifier, and solvent.
  2. 02 Practical inclusion at 0.5-10% to achieve elegant, non-greasy aesthetics, improve slip, reduce tack, and enhance the distribution of lipophilic actives in both anhydrous and emulsion systems.
  3. 03 Typically used at 2-20% as an emollient, sensory modifier, and solubilizer; it improves spreading, reduces the greasy feel of heavy oils, enhances freeze-thaw stability, and acts as an ideal solvent for sunscreens.
