Description

Technical Field

[0001] The present invention relates to a water-containing reverse micelle type transparent cleansing agent.

Background Art

[0002] Cleansing agents for washing off makeup cosmetics such as foundation and lipstick are composed of an oil agent or solvent that dissolves the constituent components of the makeup cosmetics and a high HLB nonionic surfactant for washing them away. Among them, oil cleansing agents are known to be transparent in appearance because a nonionic surfactant is stably blended in the oil agent, are characterized by their quick familiarity with makeup cosmetics, and also have excellent cleansing power.

[0003] However, these conventional oil cleansing agents contain a high HLB nonionic surfactant, so when used with wet hands or when water mixes into the container, they become an oil-in-water type emulsion, losing the transparency of their appearance, and also having problems such as a decrease in the quick familiarity with makeup cosmetics and cleansing power. Therefore, heretofore, as transparent cleansing agents that are resistant to water mixing, transparent cleansing agents containing a polyglycerol-based surfactant (see, for example, Patent Document 1), transparent cleansing agents utilizing a bicontinuous phase composed of both continuous phases of water and oil (see, for example, Patent Document 2), etc. have been developed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Since cleansing products are stored in various environments, such as in the bath and out of the bath, their functionality is not limited to how quickly they blend with makeup and their cleansing power; their stability over time in high and low temperature environments is also an important factor. The technology described in Patent Document 1 maintains its cleansing power even when water is mixed in, but it is not clear whether it maintains transparency and stability over time when the aqueous phase is already present. The technology described in Patent Document 2 can maintain both continuous phases even when some water is mixed in, so the quickness of blending with makeup cosmetics remains unchanged, but it is often unsatisfactory in terms of cleansing power compared to so-called oil-based cleansers, and it is also difficult to ensure the stability of the bicontinuous phase itself over time.

[0006] Therefore, the present invention aims to provide a new transparent cleansing agent that has high cleansing power similar to oil-based cleansing agents, while also exhibiting excellent stability over time even when containing water. [Means for solving the problem]

[0007] In light of these circumstances, the inventors, through diligent research, focused on a water-containing reverse micelle type composition as a new dosage form that is highly resistant to water contamination and has a transparent appearance. By combining a specific polyglycerin-based surfactant with an aliphatic alcohol or fatty acid that is liquid at 25°C, the inventors found that the transparency of the appearance is maintained even when a large amount of water is added, and furthermore, that the reverse micelles exhibit excellent temperature stability over time at both high and low temperatures, thus completing the cleansing agent of the present invention.

[0008] In other words, the present invention provides the following: [1] A water-containing reverse micelle type transparent cleansing agent containing the following ingredients (A) to (F). (A) Esters of fatty acids with 8-10 carbon atoms and polyglycerol (B) Esters of branched fatty acids and / or unsaturated fatty acids having 14 to 22 carbon atoms with polyglycerol (C)Aliphatic alcohols and / or fatty acids that are liquid at 25°C (D) Oils containing hydrocarbon oils (excluding component (C)) (E) Water: greater than 0% by mass and less than or equal to 10% by mass (F) Polyhydric alcohols [2] The transparent cleansing agent according to [1], wherein component (C) is decyltetradecanol and / or isostearic acid. [3] The transparent cleansing agent according to [1] or [2], wherein the ratio of the content of component (E) to the total content of component (A) and component (B); (E) / [(A)+(B)] is 0.1 to 0.5. [Effects of the Invention]

[0009] The transparent cleansing agent of the present invention maintains its high cleansing power without changing its transparency or feel when mixed with water, such as when used with wet hands. Furthermore, it exhibits excellent stability over a wide temperature range, making it suitable for storage in various environments. In addition, because the transparent cleansing agent of the present invention is a hydrated reverse micelle, it can contain water-soluble active ingredients, and the aqueous phase itself can also be expected to provide cleansing and beautifying effects. [Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described below. However, the present invention is not limited to the embodiments described below. In this specification, "X~Y" indicating a range includes X and Y, and means "X or greater and Y or less". In this specification, "transparent" refers to a material with a transmittance of 90.0% or higher for light with a wavelength of 500 nm. This transmittance is measured using a quartz cell with a path length of 10 mm and a path width of 10 mm, with water as the blank (100% transmittance), and measured with a UV-Vis spectrophotometer (UV-2600, manufactured by Shimadzu Corporation). In this specification, "liquid at 25°C" means that it has fluidity at 1 atmosphere and 25°C, and does not include paste-like or semi-solid oils, but does not particularly limit whether it is volatile or non-volatile.

[0011] Component (A): Ester of a fatty acid with 8-10 carbon atoms and polyglycerol. Component (A) used in the present invention is an ester obtained by esterifying a fatty acid having 8 to 10 carbon atoms with polyglycerin polymerized from glycerin, and is not particularly limited as long as it is commonly used in cosmetics, quasi-drugs, etc. The fatty acid used for esterification is a linear or branched saturated or unsaturated fatty acid having 8 to 10 carbon atoms. The polyglycerin has a degree of polymerization of glycerin of 4 to 10, and more preferably 6 to 8. As for the ester, a diester obtained by adding two molecules of fatty acid to polyglycerin is preferred from the viewpoint of forming hydrated reverse micelles. Component (A) can be selected and used as needed, one or more types, but it is preferable that the average HLB is 8 to 12. Specifically, an example is polyglyceryl-6 dicaprate (HLB=10.2), which is a diester of a saturated fatty acid with 10 carbon atoms and polyglycerin with a degree of polymerization of 6. A commercially available example of this is Sunsoft Q-102H-C (manufactured by Taiyo Kagaku Co., Ltd.).

[0012] In this invention, HLB (Hyrdrophile-Lipophile Balance) is an index indicating the balance between hydrophilicity and lipophilicity, and is calculated by the following formula (Equation 1) by Oda and Teramura et al., with the average HLB being a weighted average. HLB = "Inorganic value (IV) / Organic value (OV)" × 10 ... (Equation 1) (See Yoshio Koda, "Organic Concept Diagrams - Fundamentals and Applications," pp. 11-17, Sankyo Publishing, 1984)

Furthermore, the content of component (A) is preferably 5-25%, more preferably 8-20%, and even more preferably 12-17%. This range is preferable because it provides excellent long-term stability and cleansing power.

[0014] Component (B): Ester of branched fatty acids and / or unsaturated fatty acids with 14-22 carbon atoms and polyglycerol. Component (B) used in the present invention is an ester obtained by esterifying a branched fatty acid and / or an unsaturated fatty acid having 14 to 22 carbon atoms with polyglycerin polymerized from glycerin, and is not particularly limited as long as it is commonly used in cosmetics, quasi-drugs, etc. Examples of fatty acids used in esterification include those with 14 to 22 carbon atoms, specifically isopalmitic acid and isostearic acid as branched fatty acids, and oleic acid, linoleic acid, and linolenic acid as unsaturated fatty acids. For polyglycerin, a degree of polymerization of glycerin of 4 to 15 is preferred, more preferably 6 to 10. For the ester, monoesters and diesters are preferred. Component (B) can be selected and used individually or in combination of two or more as needed, but an average HLB of 10 to 15 is preferred. Specifically, examples include polyglyceryl-10 dioleate (HLB=11.9), which is a diester of an 18-carbon unsaturated fatty acid and polyglycerin with a degree of polymerization of 10; polyglyceryl-10 diisostearate (HLB=10), which is a diester of a 18-carbon branched fatty acid and polyglycerin with a degree of polymerization of 10; and polyglyceryl-10 isostearate (HLB=12), which is an ester of a 18-carbon branched fatty acid and polyglycerin with a degree of polymerization of 10.

It is also preferably 12% or less, and more preferably 10% or less. Furthermore, the content of component (B) is preferably 1 to 12%, and more preferably 2 to 10%. This range is preferable because it exhibits excellent stability over time without precipitation at low temperatures or separation at high temperatures, and also exhibits excellent cleansing power. In the present invention, although not particularly limited, the content of component (B) is preferably less than the content of component (A). For example, the ratio of the content of component (A) to the content of component (B); (A) / (B) is preferably 1.5 to 6. Within this range, a water-containing reverse micelle can be stably formed.
