example 1

[0046] Table 1 - Formulations I.

[0047]

[0048]

[0049] Preparation procedure: the Ultra L32 was added to the water and heating was initiated to 65°C. Add to PCG and mix until homogeneous. join in CPA and mix until homogeneous. Once homogeneous, the formulation was cooled to 35°C. Adjust to pH 5-6 if necessary. Formulation I exhibited a viscosity of 11,110 cps (measured using a Brookfield Viscometer Model DV-II+ at 10 RPM with a No. 4 RV spindle) and a pH of 5.5 without the use of thickening polymer.

example 2

[0051] Amphoteric surfactant to be used in formulation I Ultra L32) were replaced with the other amphoteric surfactants shown in Table 2 and the viscosity was re-evaluated each time. The results are presented in Table 2 below.

example 3

[0055]Adult body wash formulations were prepared using the materials listed in Table 3 below. All ingredients are expressed as weight percent of the total formulation. Formulation II exhibited a viscosity of 7,000-15,000 cps (measured using a Brookfield viscometer model DV-II+ with RV spindle No. 4 at 10 RPM) without the use of thickening polymer.

Abstract

An aqueous personal care composition comprising: one or more amphoacetates; one or more glutamate surfactants selected from sodium lauroyl glutamate, dipotassium cocoyl glutamate, potassium lauryl/myristoyl glutamate and combinations thereof; and cocamide MIPA; wherein the composition is free of sulfates and ethoxylates.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119(e) to U.S. Provisional Application Serial No. 62 / 459,757, filed February 16, 2017, the entire disclosure of which application is incorporated herein by reference. Background technique [0003] Currently, most commercially available personal care compositions are based on surfactants containing sulfates such as sodium lauryl sulfate (SLS), ammonium lauryl sulfate (ALS), sodium laureth sulfate (SLES) or lauryl Ammonium Alcohol Ether Sulfate (ALES). SLS, ALS, SLES and ALES are the most widely used sulphate-containing surfactants in the art because they are cheap and because they exhibit both satisfactory cleaning and foaming properties. Another advantage is that they can be easily thickened with the addition of common salts such as sodium chloride. [0004] However, personal care compositions comprising sulfate-containing surfactants also present signifi...
