Description

[Technical Field]

[0001] The presently claimed invention relates to a cleansing composition, a method of applying the cleansing composition to hair, and the use of the cleansing composition for cleansing hair, the cleansing composition comprising at least one taurate surfactant; at least one surfactant selected from the group consisting of isethionate surfactants and methyl isethionate surfactants; at least one N-acylated amino acid surfactant; and at least one betaine for use as a hair conditioning composition. [Background technology]

[0002] Hair shampoos and personal care cleaning products are generally formulated with anionic surfactants or with a combination of anionic surfactants and one or more secondary surfactants selected from other surfactant classes.Anionic surfactants are known to have excellent foaming properties, which directly relate to the perceived shampooing efficiency of the composition.In particular, sulfate surfactants, i.e., sodium lauryl sulfate and sodium lauryl ether sulfate, are often used in shampoo compositions because they are effective in generating foam.However, sulfate surfactants can be harsh on the skin and can cause hair discoloration and dryness.

[0003] Eliminating sulfate surfactants from shampoo compositions remains difficult because sulfate-free compositions typically have poor foaming properties.

[0004] EP 3416613 discloses a personal care composition containing a specific combination of anionic surfactants, one of which is a specific taurate and another of which is a specific isethionate, along with a specific amphoteric or zwitterionic surfactant, which provides acceptable foaming and conditioning properties.

[0005] WO 2020 / 043336 describes a composition containing sodium lauroyl methyl isethionate, sodium cocoyl methyl taurate, and cocoamidopropyl betaine.

[0006] EP 3079654 discloses a personal care composition containing a mixture of anionic surfactants, amphoteric surfactants, cationic substituted guar, and a copolymer of acrylamidopropyltrimonium chloride.

[0007] The methods and compositions disclosed in the prior art have limitations.

[0008] There is a need for personal care cleansing products that have good foaming properties without compromising hair conditioning performance, while at the same time being free of sulfate-containing surfactants.

[0009] It is therefore an object of the presently claimed invention to provide a cleansing composition that exhibits good foaming properties without compromising hair conditioning performance, and at the same time is free of sulfate-containing surfactants.

[0010] overview It has surprisingly been found that adding at least one N-acylated amino acid surfactant to a mixture of an anionic surfactant and at least one betaine results in the formation of a cleansing composition that exhibits good foaming properties without compromising hair conditioning performance.

[0011] Thus, in one aspect, the presently claimed invention is directed to the following cleaning composition: (A) at least one taurate surfactant in an amount of ≥1.0 to ≤8.0 wt %; (B) at least one surfactant selected from the group consisting of isethionate surfactants and methyl isethionate surfactants in an amount of ≧1.0 to ≦10.0 wt %; (C) at least one N-acylated amino acid surfactant, ≧0.5 to ≦5.0 wt.%; and (D) at least one betaine in an amount of ≧1.0 to ≦8.0 wt. %; wherein each wt. % is based on the total weight of the cleaning composition.

[0012] In another aspect, the presently claimed invention is directed to a method of washing hair comprising applying to the hair a cleaning composition of the presently claimed invention as described herein.

[0013] In another aspect, the presently claimed invention is directed to the use of the cleansing compositions of the presently claimed invention, as described herein, to cleanse hair.

[0118] Test Method Half Head Test Half-head tests were performed by stylists. Half-head comparisons allow hair stylists to evaluate the effectiveness of hair products against a defined standard. In half-head tests, depending on the styling product and / or styling technique being evaluated, a first sample was applied to one half of a model's head, and a second sample was applied to the other half of the same model's head, or compared to the untreated half of the same model's head. This test is called a half-head comparison because the test sample is applied to only half of the head, allowing for a direct comparison under identical test conditions (same hair structure, level of damage, hair color, etc.). The performance of sulfate-free shampoos according to the presently claimed invention (Compositions 2-6) was compared to the performance of Composition 1, which does not contain any acid surfactants.
