AI Technical Summary

Technical Problem

Existing personal cleansing formulations rely on palm kernel oil-derived surfactants, which contribute to deforestation and climate change, and contain sulfate and ether groups that cause skin and scalp irritation, eye irritation, and solubility issues at sub-room temperature.

Method used

A personal cleansing formulation using non-palm kernel sourced oil surfactants, such as N-acyl methyl taurate, combined with anionic and zwitterionic surfactants and adjuvants, to create a sulfate- and 1,4-dioxane-free surfactant with improved solubility, foamability, and skin/scalp mildness.

Benefits of technology

The formulation reduces deforestation impact, minimizes skin and scalp irritation, and maintains effective foaming and solubility, while reducing greenhouse gas emissions.

Abstract

A personal cleansing formulation comprises: 2-16% by weight of a non-palm kernel sourced oil surfactant, based on the total weight of the personal cleansing formulation, wherein the non-palm kernel sourced oil surfactant comprises N-acyl methyl taurate, wherein 10-20% by weight of the N-acyl methyl taurate is residual fatty acid comprising the same chain length distribution as the non-palm kernel sourced oil surfactant; 1-8% by weight of an anionic co-surfactant, based on the total weight of the personal cleansing formulation, wherein the anionic co-surfactant comprises a taurate, an isethionate, or a combination thereof, wherein the anionic co-surfactant comprises a non-palm kernel sourced oil, a non-coconut sourced oil, a palm-kernel sourced oil, or a combination thereof; 1-12% by weight of a zwitterionic surfactant, based on the total weight of the personal cleansing formulation; and 0.5-2% by weight of an adjuvant, based on the total weight of the personal cleansing composition.
