Description

[Technical Field]

[0001] The present invention claims priority to a Chinese patent application bearing application number 202310060272.X and entitled "Cleaning composition containing a surfactant system and its application examples," filed with the China Patent Office on January 18, 2023, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to cleaning compositions, and in particular to cleaning compositions containing surfactant systems and applications thereof. [Background technology]

[0003] Surfactants are the most important materials in personal cleaning care products. As the standard of living improves, people's awareness of health and environmental protection continues to grow. As a result, more and more consumers and merchants are interested in eco-friendly surfactants, especially amino acid surfactants. Among them, alkyl acyltaurate salts are excellent amino acid surfactants.

[0004] It is worth noting that the correct name for the "taurine surfactants" that have long been mass-produced on the market is alkyl acyl methyl taurine salts. Until now, there have been no commercially mass-produced alkyl acyltaurate surfactants sold or used, so alkyl acyl methyl taurine salts have always been referred to as alkyl acyltaurate salts. In reality, these two surfactants both contain functional groups with taurine structures, but whether derived from synthetic or natural sources, they are two completely different surfactants with very different properties. The applications of alkyl acyl methyl taurine salts, which are well-known on the market, are quite common. However, due to their incompetence in terms of performance, such as difficulty in increasing viscosity, cloudiness due to poor compatibility with cations, and instability, few of them are currently used as major surfactants.

[0005] Chinese Patent Application No. 201680091918.9 discloses a soap composition containing at least one cleansing agent selected from soap and a first surfactant, and at least one taurine salt surfactant selected from salts of fatty acid amides of taurine, salts of fatty acid amides of N-methyltaurine, and combinations thereof. The taurine salt surfactant is different from the first surfactant. The composition is in the form of a solid bar. Other personal care and household care products containing a taurine salt surfactant are also disclosed, and the application further defines the taurine salt surfactant as sodium oleoyl methyl taurate. Furthermore, the application primarily focuses on the research into the composition's ability to alleviate skin irritation, inflammation, and / or improve skin cell repair, and does not address the stability of the composition or the combability of the product.

[0006] In the course of research, the inventors of the present application unexpectedly discovered that when an alkyl acyl methyl taurine salt and an alkyl taurine salt are mixed and used in combination, the shortcomings of each of the two raw materials can be overcome and the advantageous features of each of them can be brought out, and the resulting cleaning care product is easier to increase in viscosity, has high transparency, good stability, and fairly good foaming and adjusting properties.

[0007] Chinese Patent Application No. 202080033788.X discloses a layered liquid composition containing an acylhydroxyethyl taurine salt, an acylmethyl taurine salt, an amphoteric surfactant, and / or a zwitterionic surfactant. The applicant has unexpectedly discovered that when the ratio of the hydroxyethyl taurine salt to the taurine salt is maintained at about 1:1, enhanced foaming is achieved. Other key factors include the ratio of the amphoteric surfactant and / or zwitterionic surfactant to the anionic surfactant, the total amount of surfactant, and pH.

[0008] However, alkylacyltaurate salts prepared using existing technology have the problem of having a Krafft point that is too high, and it should be noted that products with a 30% content tend to form lumps even at room temperature, making them inconvenient to use. Furthermore, while it is convenient for increasing viscosity and producing a transparent, stable product, it can also cause precipitation in the product, making it unstable in winter.

[0009] Therefore, there is a need to provide a cleaning composition and method for preparing the same that is less likely to deposit agglomerates even when used in winter. [Prior art documents] [Patent documents]

[Effects of the Invention]

[0060] Compared with existing technologies, the beneficial effects of the present application are: (1) In the present application, a cleansing composition is obtained by mixing and preparing an alkyl acyltaurine salt and an alkyl acyl methyl taurine salt. By controlling the blending ratio of the two, the temperature at which the creams of the two components solidify can be lowered, thereby solving the unstable state in which the two components solidify in winter, dissolve in summer, and become half-melted and half-solid in spring and autumn. (2) In this application, a cleansing composition is obtained by mixing and preparing an alkyl acyltaurate salt and an alkyl acyl methyl taurate salt. By controlling the blending ratio of the two, the effect of having viscosity, transparency at room temperature, and transparency at low temperature can be simultaneously achieved, thereby meeting the basic demand for a shampoo that does not contain silicon or sulfates on the current market. (3) In the present application, a cleansing composition is obtained by mixing and preparing an alkyl acyltaurine salt and an alkyl acyl methyl taurine salt. By combining the two, the advantages of both can be simultaneously combined, resulting in an appropriate viscosity, a fluffy and easy-to-spread cream, and good stability at high and low temperatures. That is it. DETAILED DESCRIPTION OF THE INVENTION

[0133] Application Examples A1 to A9 Sulfate-free and silicon-free clear shampoo and method for preparing same

[0134] The formulation of the ingredients is as follows:

[0135] [Table 23]

[0136] The preparation method is (1) Sodium lauroyl taurate, sodium myristoyl taurate, sodium cocoyl taurate, sodium lauroyl methyl taurate, sodium myristoyl methyl taurate, sodium cocoyl methyl taurate, and cocamidopropyl hydroxysultaine, water, and PEG-150 stearate are added, heated, stirred, and dissolved to obtain Component A. (2) After lowering the temperature, the remaining ingredients are added to ingredient A and stirred and mixed uniformly to obtain the shampoo. That is it.

[0137] Application examples A1 to A6 Sulfate-free and silicon-free clear shampoo and method for preparing same

[0138] The formulation of the ingredients is as follows:

[0139] [Table 24]

[0140] The preparation method is (1) Add sodium lauroyl taurate, sodium myristoyl taurate, sodium cocoyl taurate, sodium lauroyl methyl taurate, sodium myristoyl methyl taurate, or sodium cocoyl methyl taurate, as well as cocamidopropyl hydroxysultaine, water, and PEG-150 stearate, heat, stir, and dissolve to obtain Component A. (2) After lowering the temperature, the remaining ingredients are added to ingredient A and stirred and mixed uniformly to obtain the shampoo. That is it.

[0141] Performance measurement Please refer to Tables 25-26 for the measurement results.

[0142] Table 25. Related performance test results for sulfate-free and silicon-free clear shampoos prepared according to Application Examples A1-A9

[0143] [Table 25]

[0144] Table 26. Test results for relevant performance of sulfate-free and silicon-free clear shampoos prepared according to Application Controls A1-A6.

[0145] [Table 26]

[0146] As can be seen from Tables 25 and 26 above, when alkyl acyltaurate salts or alkyl acyl methyl taurates are used alone, it is generally difficult to achieve both viscosity and transparency. However, when alkyl acyltaurate salts are used in combination with alkyl acyl methyl taurates, the effects of viscosity, transparency at room temperature, and transparency at low temperatures can be simultaneously achieved, thereby meeting the basic demand for silicon-free and sulfate-free shampoos on the current market.

[0147] Application Examples B1 to B8 Sea salt scrub cream and its preparation method

[0148] The formulation of the ingredients is as follows:

[0149] [Table 27]

[0150] The preparation method is (1) Add sodium cocoyl taurate, sodium lauroyl taurate, sodium methyl cocoyl taurate, sodium methyl lauroyl taurate, and sodium C14-16 α-olefin sulfonate to water, glycerin, sorbitol, and sodium chloride, heat, stir, and dissolve to obtain Component A. (2) After lowering the temperature, add the remaining ingredients to ingredient A and stir and mix evenly to obtain the sea salt scrub cream. That is it.

[0151] Application comparison examples B1 to B4 Sea salt scrub cream and its preparation method

[0152] [Table 28]

[0153] The preparation method is (1) Add sodium cocoyl taurate, sodium lauroyl taurate, sodium methyl cocoyl taurate, or sodium methyl lauroyl taurate, as well as sodium C14-16 α-olefin sulfonate, water, glycerin, sorbitol, and sodium chloride, heat, stir, and dissolve to obtain Component A. (2) After lowering the temperature, add the remaining ingredients to ingredient A and stir and mix evenly to obtain the sea salt scrub cream. That is it.

[0154] Performance measurement Please refer to Tables 29-30 for the measurement results.

[0155] Table 29. Related performance test results for sulfate-free and silicon-free clear shampoos prepared according to Application Examples B1-B9.

[0156] [Table 29]

[0157] Table 30. Test results for related performance of sulfate-free and silicon-free clear shampoos prepared according to Application Control Examples B1-B6.

[0158] [Table 30]

[0159] As can be seen from Tables 13 and 14 above, when alkyl acyltaurate salt is used alone as the main surfactant in a sea salt scrub cream, the viscosity is appropriate, but the cream has a fairly strong micellar feel, is difficult to spread, requires a relatively large amount of force in actual use, and is prone to becoming rough when observed at high and low temperatures.Furthermore, when alkyl acyl methyl taurate salt is used alone as the main surfactant in a sea salt scrub cream, the viscosity is too low and although it is easy to spread, water is released when observed at high and low temperatures, and there is no texture during use.

[0160] However, when an alkyl acyltaurine salt and an alkyl acyl methyl taurine salt are used in combination, the advantages of both salts can be combined, resulting in an appropriate viscosity, a fluffy and easily spreadable cream, and good stability at high and low temperatures.

[0161] It should be noted that the above description is merely a preferred embodiment of the present invention, and those skilled in the art may make some modifications and equivalent substitutions to the technical solutions without departing from the principles of the present invention, and these modifications and equivalent substitutions shall also be considered within the protection scope of the present invention.
