Sodium isethionate, also known as sodium 2-(2-ethylhexyl)sulfosuccinate or disodium 2-ethylhexyl sulfosuccinate, is a synthetic organic compound commonly used in personal care products. It has several functions in formulations:
-
Surfactant: Sodium isethionate acts as a surfactant, which helps to reduce the surface tension between oil and water, allowing them to mix more easily.
-
Foaming Agent: It contributes to the foaming properties of cleansers, such as body washes, shampoos, and facial cleansers.
-
Cleanser: As a mild cleanser, sodium isethionate helps to remove dirt, oil, and impurities from the skin and hair without causing excessive dryness.
-
Viscosity Modifier: It can be used to adjust the viscosity of formulations, providing a thicker or thinner consistency as desired.
-
Emulsifying Agent: Sodium isethionate can act as an emulsifier, helping to stabilize mixtures of oil and water, which is important in creating stable emulsions for lotions and creams.
-
pH Adjuster: It can be used to adjust the pH of a formulation to achieve a specific balance that is suitable for the skin or hair.
-
Wetting Agent: Sodium isethionate can improve the wetting properties of a product, allowing it to spread more easily on the skin or hair.
-
Solubilizer: It can help to solubilize other ingredients in a formulation, ensuring they are evenly distributed and effective.
-
Gentleness: It is considered a milder alternative to some other surfactants, making it suitable for sensitive skin types.
-
Biodegradability: Sodium isethionate is biodegradable, which means it breaks down more easily in the environment, reducing its ecological impact.
-
Economical: It is often used for its cost-effectiveness in formulating personal care products.
Sodium isethionate is a versatile ingredient in the cosmetics and personal care industry, valued for its ability to enhance the performance and sensory experience of a variety of products. As with all ingredients, it should be used in accordance with safety guidelines and regulations.
