Embodiment

[0109] Prepare hair cleansing shampoo formulations, having the following Table 1 Ingredients shown. Examples 1 to 4 represent formulations according to the invention. Examples A to D represent comparative examples (not according to the invention).

Embodiment A

[0116] Shampoo products are used to treat the hair strands and XRF (standard procedure) is used to measure silicone deposits. The results of Examples A, B, 1 and 2 (shampoo pH 6.5) are shown in figure 1 in. The results of Examples C, D, 3 and 4 (shampoo pH 4.5) are shown in figure 2 in.

[0117] See figure 1 , When using cationic polymer Polyquaternium-10 (PQ-10) instead of cationic polymer In the case of C13S (JC13), the silicone deposition value of the comparative formulation using SLES (1EO) dropped to almost zero.

[0118] See figure 2 Regardless of the cationic polymer used, the silicone deposition value of the comparative formulation using SLES (1EO) is poor. For the formulation of the present invention using SLES (3EO), the silicone deposition ratio has C13S and the comparative formulation with Polyquaternium-10 are 3 times better.

[0119] From figure 1 with figure 2 It can be seen from the comparison that the SLES (3EO) formulation according to the present inve...

Abstract

The invention provides a personal cleansing composition having a pH ranging from 4.5 to 5.1 and comprising, in an aqueous continuous phase: (i) one or more anionic cleansing surfactants; (ii) one or more dispersed benefit agents selected from hydrophobic emulsion droplets and particulate solids, and (iii) a structuring polymer selected from alkali swellable emulsion (ASE) polymers and hydrophobically modified alkali swellable emulsion (HASE) polymers; characterized in that the one or more anionic cleansing surfactants are selected from alkyl ether sulfates of general formula (I): R-O-(CH2CH2-O)n-SO3 -M+ in which R is a straight or branched chain alkyl group having 10 to 14 carbon atoms, n is a number that represents the degree of ethoxylation and ranges from 3 to 3.5, and M is an alkali metal, ammonium or alkanol ammonium cation.

Description

Technical field [0001] The invention relates to personal cleansing compositions such as liquid soaps, body washes and shampoos. Background technique [0002] In personal cleansing compositions such as liquid soaps, body washes, and shampoos, the suspension and delivery of benefit agents are often key drivers of product performance. Beneficial agents are typically present as dispersed hydrophobic emulsion droplets (e.g. silicone) or dispersed solid particles (e.g. flake anti-dandruff actives). The problem encountered by the formulator is to keep the dispersed benefit agent suspended and the overall product stable while still providing satisfactory rheology and detergency and conditioning properties. [0003] Homopolymers and copolymers of acrylic acid have been used as structurants to provide effective thickening and effective storage and stable suspension of insoluble particles in aqueous surfactant systems. Examples of such structured polymers include carbomer, alkali swellable ...
