GLYCERYL ISOSTEARATE

Last update on Jan 17, 2025
Glyceryl Isostearate is an emollient, emulsifier, and skin conditioning agent. Glycerin and isostearic acid are combined to result in the ingredient having both hydrophilic and lipophilic characteristics. This makes it quite versatile and useful in the world of cosmetics. It softens and smooths the skin by forming a barrier and locking in moisture. It is responsible for the silky and non-greasy feel of products. For example, creams and lotions. Glyceryl Isostearate appears as a pale yellow to off-white waxy solid in its raw form. This can integrate with both oil and water phases - contributing to its popularity in the personal care and cosmetic industry. The chemical formula of Glyceryl Isostearate is C21H42O4.

What is GLYCERYL ISOSTEARATE used for?

Glyceryl Isostearate has multiple uses and benefits that make it mainstream in cosmetics. It is an excellent emollient that locks moisture in the skin to enhance hydration and skin texture. It also acts as a co-emulsifier, stabilizing oil-and-water formulations in creams, lotions, and sunscreens. In addition, this ingredient can improve product spreadability and sensory feel. Glyceryl Isostearate is a conditioning agent in hair care, reducing frizz and adding shine. Its mild, non-irritating nature makes it suitable for sensitive skin and is commonly included in cleansers, moisturizers, and anti-aging products.

Origin

Glyceryl Isostearate is synthesized through the esterification process. In this process, glycerin reacts with isostearic acid under heat and catalysts. This produces the ester and water as by-products. The water is removed to shift equilibrium, and the product undergoes purification, including neutralization, filtration, and distillation, to remove impurities. It is then dried and processed for cosmetic use.
