SODIUM DILAURETH-4 PHOSPHATE

Description

Sodium Dilaureth-4 Phosphate is a versatile surfactant and emulsifying agent commonly used in haircare formulations. This synthetic ingredient is derived from lauryl alcohol and ethylene oxide, which undergoes phosphorylation and neutralization with sodium hydroxide. Its primary function is to reduce surface tension between oil and water, allowing for the creation of stable emulsions in shampoos, conditioners, and other hair products.

The molecule consists of a hydrophilic phosphate head group and a hydrophobic alkyl chain, giving it excellent cleansing and foam-boosting properties. Sodium Dilaureth-4 Phosphate is particularly valued for its mildness on the scalp and hair, making it suitable for sensitive skin formulations. It effectively removes dirt, oil, and product buildup without causing excessive dryness or irritation.

In haircare products, this ingredient enhances the distribution of other active components, improving overall product performance. It also contributes to the smooth texture and easy application of formulations. Sodium Dilaureth-4 Phosphate is typically used in concentrations ranging from 0.5% to 5%, depending on the specific product requirements and desired effects.
