Description

Technical Field

[0001] The present invention relates to an aqueous reverse micelle type transparent cleaning agent. Background Art

[0002] Cleansers for removing makeup, such as foundation and lipstick, consist of an oil to dissolve the makeup's components, a solvent, and a high-HLB nonionic surfactant to remove them. Oil cleansers, in particular, are characterized by their transparent appearance and rapid blending into makeup, thanks to the stable blending of nonionic surfactants within the oil. They are also known to have excellent cleansing power.

[0003] However, these conventional oil cleansers contain high-HLB nonionic surfactants. Therefore, when used with wet hands or if water is added to the container, they form an oil-in-water emulsion, losing their apparent transparency. Furthermore, they have issues with rapid blending with makeup and reduced cleansing power.

[0004] Therefore, to date, as transparent cleansers that are strongly resistant to water intrusion, transparent cleansers containing polyglycerol-based surfactants (for example, see Patent Document 1) and transparent cleansers utilizing a bicontinuous phase consisting of a bicontinuous phase of water and oil (for example, see Patent Document 2) have been developed.

[0007] Patent Document 1: Japanese Patent Application Laid-Open No. 2018-070481

[0008] Patent Document 2: Japanese Patent Application Laid-Open No. 2010-280643 Summary of the Invention

[0009] Problems to be solved by the invention

[0010] Cleansers are stored in various environments, both inside and outside the bathroom. Therefore, their functionality as a cleanser depends not only on their quick integration with makeup and cleaning power, but also on their stability over time in high and low temperature environments.

[0011] The technology of Patent Document 1 shows that even with the addition of water, cleansing power is not easily reduced. However, it is unclear whether transparency and temporal stability are maintained in a state where a water phase is pre-existing. The technology of Patent Document 2 maintains the bicontinuous phase even with the addition of a small amount of water, thus maintaining rapid integration with makeup. However, compared to so-called oil-based cleansers, the cleansing power is often unsatisfactory, and it is also difficult to ensure the temporal stability of the bicontinuous phase itself.

[0012] Therefore, an object of the present invention is to provide a novel transparent detergent having high cleaning power similar to that of an oil-based detergent and excellent stability over time even when containing water.

[0013] Means used to solve problems

[0014] In light of this reality, the present inventors conducted intensive research and, as a result, focused on aqueous reverse micelle compositions as a new formulation that is highly resistant to water intrusion and exhibits a transparent appearance. Furthermore, they discovered that by combining a specific polyglycerol-based surfactant with aliphatic alcohols and / or fatty acids that are liquid at 25°C, the composition maintains transparency even when a large amount of water is added. Furthermore, the reverse micelles exhibit excellent temperature stability over time at both high and low temperatures, resulting in the completion of the cleanser of the present invention.

[0015] That is, the present invention provides the following technical solutions.

[0016] [1] An aqueous reverse micelle type transparent detergent comprising the following components (A) to (F).

[0017] (A) esters of fatty acids having 8 to 10 carbon atoms and polyglycerol;

[0018] (B) esters of branched fatty acids and / or unsaturated fatty acids having 14 to 22 carbon atoms and polyglycerol;

[0019] (C) aliphatic alcohols and / or fatty acids that are liquid at 25°C;

[0020] (D) an oil containing hydrocarbon oil (excluding component (C));

[0021] (E) water exceeds 0 and is 10% by mass or less;

[0022] (F) Polyol.

[0023] [2] The transparent cleaning agent according to [1], wherein the component (C) is decyltetradecyl alcohol and / or isostearic acid.

[0024] [3] The transparent cleaning agent according to [1] or [2], wherein the ratio (E) / [(A)+(B)] of the content of the component (E) to the total content of the components (A) and (B) is 0.1 to 0.5.

[0025] Effects of the Invention

[0026] The transparent cleanser of the present invention maintains its transparency and feel even when mixed with water, such as when used with wet hands, maintaining high cleaning power. Furthermore, its excellent temporal stability over a wide temperature range allows for storage in various environments. Furthermore, since the transparent cleanser of the present invention is an aqueous reverse micelle, it can contain water-soluble active ingredients, and can also be expected to achieve cleansing and beauty effects from the aqueous phase itself.
