Sodium Isostearoyl Lactylate in Liquid Soap

Sodium Isostearoyl Lactylate acts as a water-in-oil binder or emulsifier. According to the product information, its recommended usage rate is 1-5% of the total formulation.

This percentage refers to the amount of the Sodium Isostearoyl Lactylate emulsifier itself that should be used in the formula, not the maximum percentage of oil it can emulsify.

The maximum amount of oil that can be successfully emulsified depends on various factors in the specific formulation, such as the type of oil used, the presence of other ingredients (like co-emulsifiers or thickeners), and the desired stability and consistency of the final liquid soap product. The product description provides the recommended usage rate for the emulsifier but does not specify a maximum oil load percentage it can handle in a liquid soap application.
