Stearic acid is a common ingredient found in cosmetic formulations because of its versatile properties. It functions primarily as an emulsifier, thickener, and lubricant when added to skin care products. It also helps to bind ingredients together that would not typically mix, such as oil and water. It is a white, waxy substance that can be derived from animal and vegetable fats.

Fatty acids are the building blocks for fats and oils. The most common fatty acids in the world include palmitic, oleic, and lauric acid. These are also the fatty acids that are found naturally in many foods, including shea butter and cocoa butter.

The use of fatty acids in skin care is important because they can help to improve the texture, spreadability, and stability of products. These benefits contribute to a better product experience for the consumer.

According to the Cosmetics Database, stearic acid is considered safe for both producers and consumers of skincare products. This is because it is a non-reactive and low-risk chemical that is easy for manufacturers to handle.

Unlike some surfactants that can strip your skin of its natural oils, stearic acid does not have this effect. This makes it a good ingredient to add to cleansing products, as it will not disrupt your skin’s moisture balance or cause dryness. Stearic acid can also help your products apply more evenly. This is because it can bind with other ingredients to make them stick together and not slide off your face.
