Embodiment Construction

[0035] Referring to Table 2 below, Example 2 is a comparative example describing the method and properties of compositions made from two gel premixes mixed with personal care components. Gel network A has a weight ratio of fatty amphiphile / surfactant (FA:S) greater than 1 (specifically 2.54), and according to the composition of the invention, gel network B has a weight ratio of less than 1 (specifically 2.54). The weight ratio of FA:S is about 0.77).

Abstract

The present application relates to a process for preparing a personal care composition by combining a fatty amphiphile above its melt temperature and a surfactant in a weight ratio from 0.1:1 to 0.99:1 to form a gel network premix contacting the gel network premix with a shearing device, cooling the gel network premix to a temperature below the melt temperature of the fatty amphiphile and adding the cooled premix to personal care components to form the personal care composition.

Description

technical field [0001] Embodiments of the present disclosure generally relate to personal care compositions and methods of making the same, and in particular to personal care compositions comprising a surfactant-rich gel network. Background technique [0002] In the case of personal care formulations such as cosmetic creams and hair conditioners, it is known to contain gel network premixes to impart conditioning benefits to personal care formulations. US 7,303,744 to Wells et al. (hereinafter the '744 patent) discloses the preparation of a fatty alcohol / surfactant gel network premix to be added to a personal care base formulation to provide conditioning benefits. Formation of the gel network involves heating a dispersion of fatty amphiphile and surfactant to a temperature above the melting point of the fatty amphiphile. When the mixture cools, it transforms into a solid crystalline gel network. [0003] The '744 patent proposes a gel network premix having a fatty amphiphil...
