SODIUM ISOSTEARATE

Description

Sodium Isostearate is a versatile and effective surfactant commonly used in skincare and cosmetic formulations. This sodium salt of isostearic acid serves as an emulsifier, helping to blend oil and water-based ingredients in various products. Its unique structure allows it to form stable emulsions, making it particularly valuable in creams, lotions, and cleansers.

In skincare applications, Sodium Isostearate exhibits mild cleansing properties while maintaining skin hydration. It helps to remove dirt, oil, and impurities without overly stripping the skin's natural oils. This ingredient is known for its ability to create rich, creamy textures in formulations, enhancing the sensory experience of products.

Sodium Isostearate is generally well-tolerated by most skin types, including sensitive skin. It has a low potential for irritation and is often used in gentle, pH-balanced cleansers. The ingredient also functions as a thickening agent, contributing to the desired consistency of skincare products.

Furthermore, Sodium Isostearate can act as a solubilizer, helping to incorporate oil-soluble ingredients into water-based formulations. This property makes it useful in creating clear solutions and transparent products. Its effectiveness in various pH ranges adds to its versatility in product development.
