Description

Technical Field

[0001] The present invention relates to a cleaning composition, and more particularly to a cleaning composition that provides a long-lasting cleaning effect on keratin materials (such as hair and scalp).

[0002] Background

[0003] Skin is widely present on the surface of the human body. For a long time, many people have pursued a fresh body surface to feel comfortable in daily life and work. Endowing products with skin care effects such as moisturizing, anti-aging, whitening, cleaning, and smooth feeling has always been the ultimate goal in the beauty field.

[0004] Oily scalp and hair are becoming troublesome scalp problems globally; people usually use anti-oil shampoos to remove dirt and sebum on the scalp. However, consumers are not satisfied with the long-lasting cleaning between two hair washes. Currently common shampoos contain surfactants as detergents, and their purpose is usually to remove the newly secreted liquid sebum. The liquid sebum composition will be decomposed by fungi and bacteria on the scalp and form stubborn sebum together with dead cells. In order to effectively clean oily scalp, the ability of ordinary shampoos to remove stubborn sebum still needs to be improved. Therefore, the use of surfactants in cleaning products needs to be improved.

[0005] Acids are widely used in beauty. For example, acids can play a role in unlocking the SC desmosomes, which are key parts of cell junctions. Specifically, acids, such as α-hydroxy acids or β-hydroxy acids, help remove the connection structure between keratins in the stratum corneum and produce a mild effect of dissolving keratin. However, with the addition of acids, the pH of the composition will decrease, resulting in a reduction in the amount of foam.

[0006] Therefore, there is still a need in the art to develop a new composition suitable for the desired cleaning properties of oily keratin materials (such as scalp and hair) and having rich, stable, and soft foam. Summary of the Invention

[0007] Through in-depth research, the inventors unexpectedly found that by using specific anionic surfactants, amphoteric surfactants, hydroxy acids, and organic basifying agents, the composition can provide improved cleaning properties, such as a long-lasting cleaning effect, on keratin materials, such as hair and scalp, and has rich, stable, and soft foam.

[0008] Therefore, one subject of the present invention is a composition comprising:

[0009] A) at least one sulfur-containing anionic surfactant;

[0010] B) at least one betaine-derived amphoteric surfactant selected from sultains;

[0011] C) at least one α-hydroxy acid;

[0012] D) at least one β-hydroxy acid;

[0013] E) at least one organic basifying agent selected from alkanolamines.

[0014] The composition according to the invention is particularly suitable for products requiring a long-lasting cleaning effect, especially for products for hair and scalp. Therefore, the composition of the invention can be used particularly in cleaning products for hair and scalp, for example, in shampoos that provide rich and stable foam.

[0138]

[0139] Example A

[0140] For different purposes, inventive examples Ex.1 - Ex.4 according to the invention and comparative examples CE.1 - CE.3 were prepared.

[0141] Table 1

[0142]

[0143] The above compositions were prepared according to manufacturing methods known in the art. Briefly, for example, the procedure for preparing the composition of Ex.1 includes the following steps:

[0144] 1). Add lactic acid, salicylic acid, and triethanolamine, and stir until dissolved;

[0145] 2). Add surfactants (sodium lauryl polyether sulfate, coconut amide propyl hydroxysulfobetaine), and mix until transparent; and

[0146] 3). If necessary, adjust the pH to the specified value. If the pH is below 3.8, add triethanolamine until the pH equals 3.8; if the pH is above 3.8, add lactic acid until the pH equals 3.8.

[0147] Example B

[0148] Evaluate the foaming performance of the composition of Example A according to the following steps:

[0149] For the foam volume test protocol:

[0150] a. Prepare water with a hardness of 10 fH (dissolve 111 mg of CaCl 2 in 1 L of DI water);

[0151] b. Weigh 4 g of the composition to be tested and place it in a kitchen blender;

[0152] c. Weigh 76 g of the prepared 10 fH water and dilute the composition 20 times;

[0153] d. Turn on the kitchen blender and mix for 1 minute;

[0154] e. Quickly transfer the generated foam and liquid to a 500 - milliliter graduated cylinder; and

[0155] f. Read the total volume.

[0156] The higher the foam volume number, the richer the foam.

[0157] For the stable foam test protocol:

[0158] a. Prepare water with a hardness of 10 fH (dissolve 111 mg of CaCl 2 in 1 L of DI water);

[0159] b. Weigh 4 g of the shampoo to be tested and place it in a kitchen blender;

[0160] c. Weigh 76 g of the prepared 10 fH water and dilute the shampoo 20 times;

[0161] d. Turn on the kitchen blender and mix for 1 minute;

[0162] e. Quickly transfer the generated foam and liquid to a 500 - milliliter graduated cylinder; and

[0163] f. Read the height of the drainage at 1 minute with a ruler

[0164] The smaller the value of the drainage height, the more stable the foam is.

[0165] The foam smoothness of each shampoo is evaluated as follows:

[0166] Treat the hair with the test shampoo:

[0167] Select a bundle of damaged hair. Comb the hair and wet it under running water. Apply the test shampoo evenly from the root to the tip of the damaged hair. Gently massage the shampoo from the root to the tip of the hair (not knotted) with two fingers to make the shampoo foam.

[0168] Collect the foam from the hair surface onto the hand and judge the degree of no resistance when the fingers slide through the hair.

[0169] In the above foam evaluation, Ex.1 is used as a benchmark parallel to the test shampoo. Six volunteers were recruited and asked to rate the foam smoothness of each test shampoo.

[0170] The foam smoothness rating criteria for each test shampoo are as follows.

[0171] --: The test shampoo is significantly lower than the benchmark;

[0172] -: The test shampoo is slightly inferior compared to the benchmark;

[0173] =: The test shampoo is similar to the benchmark;

[0174] +: The test shampoo is slightly better than the benchmark;

[0175] ++: The test shampoo is significantly better than the benchmark.

[0176] The results are provided in Table 2 below:

[0177] Table 2:

[0178]

[0179] It can be seen that the inventive examples have achieved ideal effects in terms of the volume, stability, and softness of the foam. In contrast, the comparative examples are inferior in one or more effects.
