Pentaerythrityl TetraisostearateBarrier
Synthetic ester emollient. Cushioning skin feel; common in 'silicone-free' moisturizers as a silicone alternative.
What it does
Pentaerythrityl tetraisostearate is a heavier ester emollient that gives formulations a silicone-like cushioning feel without using silicones. Common in moisturizers and lipsticks marketed as silicone-free. Higher comedogenic potential than caprylic/capric triglyceride, so worth flagging on acne-prone skin if it's high on the INCI.

moderateSome occlusives (cocoa butter, coconut oil, isopropyl myristate, certain plant butters) can be comedogenic on acne-prone skin. Lighter occlusives (squalane, mineral oil, hyaluronic acid, glycerin) are generally non-comedogenic in published data.Kligman 1972 · Archives of Dermatology ↗
