CAPRYLIC/CAPRIC/MYRISTIC/STEARIC TRIGLYCERIDE.

Valuable CAS 208126-53-8 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SKIN PROTECTING

A specialized fatty acid ester blend designed to provide an elegant, skin-mimetic barrier that transitions from solid to liquid upon contact. It serves as a high-performance emollient that balances long-lasting protection with a refined, non-greasy skin feel.

Summary

Emollient Skin-conditioning agent Penetration enhancer Texture modifier

Science

Mechanism of Action

This triglyceride utilizes a specific chain length distribution (C8-C18) to melt precisely at skin temperature (39-42°C), creating a lightweight, non-occlusive film that prevents transepidermal water loss. Beyond surface conditioning, it acts as a molecular transporter, enhancing the penetration of lipid-soluble actives and vitamins into the deeper epidermal layers.

Key findings

  1. 01 Clinical evaluation of triglyceride-based facial oils confirmed zero detectable sensitization or photocontact potential at concentrations up to 95.6%.
  2. 02 Thirteen-week dermal safety assessments at 4.0% concentration demonstrated no localized irritation or systemic toxicity.
  3. 03 Technical performance data indicates optimal oxidative stability and protective film formation when formulated between 2% and 30%.

Because it functions as a primary texture modifier and emollient, it is rarely 'dusted' at negligible levels; however, concentrations below 2% may fail to provide the intended barrier-repair benefits.
