What is ISOSTEARYL NEOPENTANOATE used for?
Isostearyl Neopentanoate is used in cosmetics to improve spreadability, texture, and skin feel. It delivers hydration without heaviness and is prized in formulations that require a dry, elegant finish.
For skin: Isostearyl Neopentanoate is a fast-absorbing emollient that softens and smooths the skin without leaving a greasy residue. It creates a light, breathable barrier that helps reduce moisture loss, making it ideal for moisturizers, primers, and sunscreens. Its velvety texture enhances the sensory feel of products and improves the glide of formulations, particularly in makeup and facial creams.
For hair: In hair care, Isostearyl Neopentanoate helps improve spreadability and slip - especially in serums, leave-in conditioners, and styling products. It gives the hair a soft, conditioned feel without weighing it down or making it greasy. It also helps to smooth the hair cuticle, reducing frizz and static while adding a light shine. Its dry-touch finish is especially useful for fine hair types or formulations intended for daily, non-greasy use.
Origin
Isostearyl Neopentanoate is made through an esterification reaction between isostearyl alcohol and neopentanoic acid. The reaction takes place in the presence of a catalyst under controlled heat. The resulting ingredient - Isostearyl Neopentanoate - has a dry, silky feel. This synthetic production ensures consistency, long shelf life, and suitability for a wide range of cosmetic applications.
