Use & Benefits:

Pentaerythrityl tetraoctanoate is used as an emollient in many cosmetic products. Since it has certain chemical groups that can hold a lot of moisture for the skin, it offers instant relief in case of dry and flaky skin. It forms a protective barrier on the skin and protects it from loss of moisture. As we age, the upper layer or epithelium loses integrity and we start losing moisture. Dry skin is more prone to infiltration or passage of harmful things like allergens, bacteria, and irritants to pass into the deeper layers of the skin. This leads to infections like acne, eczema, dry and patchy skin. So, when emollient is used it brings the tightness, moisture level, and partial integrity of the skin back. Pentaerythrityl tetraoctanoate also acts as a conditioning agent and makes skin more hydrated, softer, and silky. Italso conditions hair and makes it appear soft, silky, and lustrous. It is used in formulations of many products like moisturizers, conditioners, gels, and other skin and hair care products.
