Polysorbate is a non-ionic surfactant and emulsifier derived from sorbitol and fatty acids, often sourced from natural origins such as vegetable oils. The scientific name *Polysorbate* refers to a family of compounds that includes various esters of sorbitan (a sugar alcohol) and fatty acids, designated by a number that represents the specific fatty acid (e.g., Polysorbate 20, Polysorbate 80). The Polysorbate nomenclature arose from its chemical structure and its function, denoting it is a polymer (polysorbate) of sorbitol. The ingredient has been commonly used in the cosmetics and personal care industry since its introduction in the mid-20th century due to its versatile properties and effectiveness as an emulsifier.
Polysorbate is widely used in the formulation of skincare products due to its ability to stabilise mixtures of oil and water. It facilitates the incorporation of oil-soluble ingredients into water-based formulations, ensuring a smooth texture and even distribution of active components. Given its emulsifying properties, Polysorbate plays a critical role in enhancing cosmetic formulations, making them more palatable and effective for end-users.
- Effective emulsification: Acts as a highly effective emulsifier, allowing oil and water-based ingredients to mix smoothly, enhancing the overall texture and stability of skincare products.
- Improved absorption: Improves the absorption of skin-beneficial ingredients, ensuring that nutrients penetrate better into the skin.
- Enhanced spreadability: Enhances the spreadability of products, making application easier and more luxurious, effectively covering a greater area with minimal product.
- Stabilises formulations: Stabilises formulations, helping to maintain consistency and preventing separation of ingredients, which is crucial for product longevity and user satisfaction.
- Even scent dispersion: Can help disperse natural fragrances and essential oils in water-based products, ensuring an even scent distribution without surface tension issues.
- Creamy texture creation: Assists in creating a creamy and rich texture in cleansers, lotions, and creams, improving user experience by providing a soft, pleasant feel on the skin.
- Reduces irritation: In some formulations, Polysorbate can also aid in the prevention of skin irritation by improving the way certain active ingredients interact with the skin.
Kissed Earth incorporates Polysorbate in their Enzymatic Cream Cleanser, which features an array of Australian botanical extracts designed to brighten the skin while providing a deep cleanse. The inclusion of Polysorbate in this formulation not only helps with the emulsification of oil and water-based ingredients but also ensures that the nourishing properties of organic Coconut, Macadamia, and Squalene oil remain effective. The fruit enzyme complex of Desert Lime and Papaya works synergistically with Polysorbate to dissolve makeup and impurities gently, leaving the skin feeling clean yet balanced. As a result, the formulation maintains the skin's natural oils while providing a thorough cleanse, making it suitable for both morning and night use.
