Pentaerythrityl Tetraisostearate

Harm score: 3 (Harmless chemicals)

Pentaerythrityl Tetraisostearate, also known as rosewood, rosewood, pau rosa or cara-cara, is a chemical that is often used in the cosmetic industry. This substance is produced synthetically and is commonly used as an ingredient in various skin care and makeup products, including lipsticks, lipglosses, creams and moisturizers for the skin, but also in personal care products.

Pentaerythrityl Tetraisostearate acts as an emollient, meaning it is able to soften and smooth the skin, while also providing better distribution of the other ingredients in the product. Due to its properties, it also helps retain water in the skin, thus contributing to its hydration. This use of it is particularly useful in lip balms and lipsticks, where it helps to moisturize and soften the lips without leaving a greasy feeling. In addition, it also prevents water loss and thus reduces skin dryness, which contributes significantly to the overall appearance and health of the skin. Besides cosmetic products, Pentaerythrityl Tetraisostearate is also used in some pharmaceutical products.

However, it is important to note that any use of Pentaerythrityl Tetraisostearate should comply with safety guidelines and regulations. Although it is a generally safe ingredient, some people may have an allergic reaction to it. Therefore, it is always recommended to test a small area of skin before using a new product that contains this chemical.
