SODIUM C11-15 ALKYL SULFATE

Description

SODIUM C11-15 ALKYL SULFATE is a synthetic surfactant commonly used in personal care and cosmetic products. This anionic compound belongs to the alkyl sulfate family and is derived from long-chain fatty alcohols. It functions primarily as a cleansing agent and foaming enhancer in various formulations.

The ingredient's molecular structure consists of a hydrophilic sulfate head group and a hydrophobic alkyl chain, typically ranging from 11 to 15 carbon atoms in length. This amphiphilic nature allows it to effectively emulsify oils and suspend dirt particles, making it an efficient cleanser for skin and hair products.

SODIUM C11-15 ALKYL SULFATE exhibits excellent foaming properties, producing a rich, stable lather that consumers often associate with thorough cleansing. It is generally milder than shorter-chain alkyl sulfates, such as sodium lauryl sulfate, making it suitable for use in products intended for sensitive skin.

In formulations, this ingredient is typically used at concentrations between 1% and 15%, depending on the product type and desired effect. While effective, formulators should be aware that higher concentrations may potentially cause skin irritation in some individuals, particularly those with very sensitive skin.
