Description

Technical Field

[0001] The present invention relates to a transparent and liquid hair cleaning composition that can build viscosity in a shampoo formulation without using a high content of polymers or nonionic surfactants for an amino acid type surfactant that is considered difficult to thicken, is easy to rinse during hair washing, and has excellent temporal stability and a refreshing feeling after hair washing.

Background Art

[0002] Amino acid type surfactants are surfactants with high safety for the body and have been widely used as main bases in shampoos in recent years. In addition to performance such as detergency, foaming, and foam quality, shampoos also require a viscosity for using an appropriate amount during washing. However, it is known that amino acid-based surfactants are bases that are difficult to form a high-viscosity formulation during blending. Generally, in order to build viscosity in shampoos, polymers or nonionic surfactants are often used (Non-Patent Document 1). For example, in Patent Document 1, thickening is achieved by blending a nonionic surfactant, but there are cases where temporal stability is lacking.

[Means for solving the problem]

[0006] The inventors of this invention conducted extensive research to solve the above problems and found that the above problems can be solved with a transparent liquid hair cleansing composition in a specific pH range, comprising potassium cocoyl-β-alanine, a specific N-acyl amino acid salt, an amphoteric surfactant, a nonionic surfactant, and a cationized polymer. Furthermore, they found that the problematic aspects of long-term stability, rinsability during washing, and the refreshing feeling after washing were also improved, thus completing the present invention.

[0007] In other words, the present invention is as follows: (1) (A) 0.5 to 4.0% by weight of potassium cocoyl-β-alanine represented by general formula (1), [ka] (In the above general formula (1), RCO is a coconut fatty acid residue, or palm nuclear (Indicates fatty acid residues.)

[0008] According to the present invention, it is possible to achieve viscosity in a shampoo formulation without using high concentrations of polymers or nonionic surfactants, which are considered difficult to thicken with amino acid-type surfactants. This provides a transparent, liquid hair cleansing composition that is easy to rinse during washing, leaves the hair feeling refreshed after washing, and has excellent long-term stability.

[0009] <Inventive Thickening Mechanism> Generally, amino acid-type surfactants have large hydrophilic groups and small critical packing parameters, making them prone to forming spherical micelles. On the other hand, potassium cocoyl-β-alanine is a secondary amide-type surfactant with a smaller hydrophilic group compared to conventional amino acid-type surfactants. Therefore, it is presumed that incorporating potassium cocoyl-β-alanine increases the critical packing parameter, leading to a change in micelle structure from spherical to rod-shaped and then to string-shaped micelles, thereby increasing viscosity.

Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described. The component (A) is cocoil-β-alanine potassium represented by the general formula (1).

Chemical Formula

[0011] As a method for producing cocoil-β-alanine potassium, for example, it can be obtained by subjecting coconut fatty acid chloride or palm kernel fatty acid chloride and β-alanine to a nucleophilic substitution reaction under alkaline conditions. Coconut fatty acid chloride and palm kernel fatty acid chloride may be used alone or in combination of two or more. Further, cocoil-β-alanine potassium may contain free fatty acids by-produced during the nucleophilic substitution reaction.

[0012] The component (A) is preferably added to the hair cleansing composition at 0.5 to 4.0% by weight. More preferably, it is 1.0 to 3.0% by weight. If it is less than 0.5% by weight, the thickening effect, the ease of rinsing during hair washing, and the refreshing feeling after hair washing of the amino acid type surfactant of the present invention may not be felt. If it exceeds 4.0% by weight, the component (A) may precipitate, resulting in poor stability over time.

[0014] The content of component (B) in the hair cleansing composition is preferably 3.0 to 15.0% by weight. More preferably 4.0 to 12.0% by weight. If it is less than 3.0% by weight, the thickening effect of the N-acyl amino acid salt of the present invention, ease of rinsing during hair washing, and refreshing feeling after washing may not be felt. If it is more than 15.0% by weight, the thickening effect of the N-acyl amino acid salt, ease of rinsing during hair washing, and refreshing feeling after washing may not be felt. Component (B) may be used alone or in combination of two or more types.

[0015] The ratio of component (A) to component (B) should preferably be between 0.03 and 1.33. If the ratio of component (A) to component (B) is less than 0.03, the thickening effect, ease of rinsing during shampooing, and refreshing feeling after shampooing may not be felt. If the ratio of component (A) to component (B) exceeds 1.33, component (A) may precipitate, resulting in poor stability over time. The ratio of component (A) + component (B) should preferably be between 3.5 and 19.0% by weight. If the ratio of component (A) + component (B) is less than 3.5% by weight, the balance of the hair cleansing agent composition may be disrupted, resulting in poor stability over time. In addition, thickening effect may not be obtained. If the ratio of component (A) + component (B) exceeds 19.0% by weight, component (A) and component (B) of the hair cleansing agent composition may precipitate, resulting in poor stability over time.

[0016] <Desalting and purification of amphoteric surfactants> It is preferable to use desalted and purified amphoteric surfactants. Methods for desalting and purifying amphoteric surfactants include reverse osmosis, electrodialysis, ion exchange resin, solvent extraction, and recrystallization.

[0018] The content of component (C) in the hair cleansing composition is preferably 2.0 to 12.0% by weight. More preferably 3.0 to 10.0% by weight. If it is less than 2.0% by weight, the balance of the hair cleansing composition may be impaired and its stability over time may be poor. In addition, viscosity and ease of rinsing during shampooing may not be obtained. If it exceeds 12.0% by weight, the stability over time may be poor due to the effect of salts contained in the amphoteric surfactant. In addition, ease of rinsing during shampooing may not be obtained. Component (C) may be used alone or in combination of two or more types.

[0019] (C) The sodium chloride concentration of the amphoteric surfactant is preferably 1.0% by weight or less relative to the total weight of the aqueous solution of the amphoteric surfactant component. The amphoteric surfactant does not need to contain salt. If the sodium chloride concentration of the amphoteric surfactant exceeds 1.0% by weight, the long-term stability of the hair cleansing composition may deteriorate due to the effect of the salt contained in the amphoteric surfactant.

[0029] The effects of the present invention will be described in more detail by the following examples, but the present invention is not limited to these examples. In the examples, unless otherwise specified, the components used were purchased from Fujifilm Wako Pure Chemical Industries, Ltd.

[0030] Manufacturing example (Production of potassium cocoyl-β-alanine) In a 500 ml four-neck separatory funnel, 169 g of soft water, 27.4 g of β-alanine, and 68.8 g of a 48 wt% aqueous solution of potassium hydroxide were added and stirred until completely dissolved. 69.1 g of coconut oil fatty acid chloride (HAIHANG INDOUSTRY) was then added dropwise over approximately 1 hour. After the addition was complete, the mixture was stirred for at least 30 minutes, and then 33.2 g of 75 wt% sulfuric acid was added and the mixture was separated. The oil layer was washed with 136 g of soft water and then diluted again with soft water to the desired concentration (25-30%). A 48 wt% aqueous solution of potassium hydroxide was added dropwise to adjust the pH to 8.5-9.0 to obtain the target product. The structure of the target product is: 1 This was confirmed using 1H-NMR (JEOL Ltd., JNM-E CZ400S). 1 ¹H-NMR chemical shifts were 0.65-0.80 ppm (3H m), 1.0-1.3 ppm (17H m), 1.4 ppm (2H m), 2.1 ppm (2H m), 2.3 ppm (2H m), and 3.2 ppm (2H m). The lauric acid content was quantified by high-performance liquid chromatography (column: Inertsil® ODS-2, 150 mm, manufactured by GL Sciences Co., Ltd.). The result was 1.5% by weight. Since coconut oil fatty acid chloride with a composition ratio of 50.8% lauric acid chloride was used, the total free fatty acid content was 3.0% by weight.
