Isononyl Isononanoate is a synthetic emollient commonly used in skincare and cosmetic products. It is a clear, colorless, and odorless liquid that is derived from isononanoic acid and isononyl alcohol. In plants, it can be found in some essential oils, such as lemongrass oil and citronella oil. In animals, it can be found in some milk and dairy products, as well as in certain fish species such as herring and mackerel.

• Emollient properties: It works as a moisturizer by creating a barrier on the skin that helps to prevent water loss and maintain skin hydration.

• Improved texture: Isononyl isononanoate has a lightweight texture that helps to improve the texture of skincare products, making them feel smoother and more luxurious.

• Enhanced skin absorption: It has the ability to enhance the penetration of other ingredients into the skin, allowing them to work more effectively.

• Non-comedogenic: It is non-comedogenic, which means that it does not clog pores or contribute to the formation of acne.

Isononyl isononanoate is commonly found in a variety of skincare and cosmetic products, including moisturizers, serums, sunscreens, and makeup. It is generally considered safe for use in these products, although individuals with sensitive skin may want to exercise caution and perform a patch test before using it.
