Description

Cleansing composition The present application claims priority to Japanese Patent Application No. 2023-143824, and the said application is incorporated into the description of the present specification by reference. The present invention relates to a cleansing composition. Conventionally, cleansing compositions used to remove cosmetics, etc. attached to the skin or hair are known, for example. As a cleansing composition of this type, for example, a cleansing composition comprising at least an oil and an acrylic water-soluble copolymer is known (Patent Document 1). In detail, the cleansing composition described in Patent Document 1 contains 50 to 91 mass% of a polyhydric alcohol containing glycerin, 0.25 to 4 mass% of (behenic acid/eicosanic acid) polyglyceryl-10, 1 to 23 mass% of a nonionic surfactant with an HLB of 5 to 17, 5 to 38 mass% of one or more selected from oily waxes and/or liquid oils, 0.001 to 0.36 mass% of one or more selected from specific acrylic water-soluble copolymers, organic acids, and salts of said organic acids, and 10 mass% or less of water. The cleansing composition described in Patent Document 1 can remove used makeup cosmetics, etc. that are attached to the skin, etc. [Fig. 1] This is a graph showing the cleansing performance (relative value) of a cleansing composition. One embodiment of a cleansing composition according to the present invention is described below. The cleansing composition of the present embodiment is, (A) Hydrocarbon oil with a molecular weight of 400 or less, and, (B) an amphiphilic liquid oil having multiple ether groups in the molecule, and (C) A water-soluble acrylic polymer having a constituent unit derived from (meth)acrylic acid in the molecule, and (D) an oil gelling agent having a cross-linked polymer molecular structure, and (E) Contains at least one of alkali metal ions or magnesium ions. The cleansing composition of the present embodiment has good cleansing performance. In other words, the cleansing composition of the present embodiment can sufficiently remove cosmetics attached to the skin or hair. The cleansing composition of the present embodiment preferably further comprises water, a surfactant (F), and an oily component (G) other than (A) and (B). The cleansing composition of the present embodiment is, for example, an emulsified formulation in which an oily component is dispersed in an aqueous component. The cleansing composition of the present embodiment can be used to remove, for example, makeup cosmetics applied to the skin, eyebrows, or eyelashes, or hair styling agents applied to the hair. The makeup cosmetics to be removed are, for example, foundation applied to the skin, lipstick applied to the lips, eyeshadow or eyeliner applied to the eyelids, eyebrow pencil applied to the eyebrows, or mascara applied to the eyelashes. The hair styling agents to be removed are, for example, styling agents applied to the hair, hair oil, hair gel, or hair styling agents for hairspray. In addition, the designation "composition for cleansing" refers to a composition for removing used cosmetic residue (makeup) that has been attached to the skin or hair, etc. <(A) Hydrocarbon oils with a molecular weight of 400 or less> The above hydrocarbon oil (A) is a hydrocarbon compound having only carbon [C] and hydrogen [H] in its molecule. The above hydrocarbon oil (A) is typically in a liquid state at 20°C. The above hydrocarbon oil (A) may include straight-chain hydrocarbons, branched-chain hydrocarbons, or cyclic hydrocarbons. The above hydrocarbon oil (A) may also be a mixture of hydrocarbon compounds with different carbon numbers. The above hydrocarbon oil (A) is preferably a saturated hydrocarbon compound, but may also include an unsaturated hydrocarbon compound. Examples of the above hydrocarbon oil (A) include octane (molecular weight approximately 114), nonane (molecular weight approximately 128), decane (molecular weight approximately 142), undecane (molecular weight approximately 156), dodecane (molecular weight approximately 170), tridecane (molecular weight approximately 184), tetradecane (molecular weight approximately 198), pentadecane (molecular weight approximately 212), hexadecane (molecular weight approximately 226), heptadecane (molecular weight approximately 240), octadecane (molecular weight approximately 254), nonadecane (molecular weight approximately 268), etc. These hydrocarbon compounds may be in a straight chain or branched chain form as described above. That is, for example, the above octane may be normal octane (n-octane) or isooctane (iso-octane). The same applies to the aforementioned hydrocarbon oils other than octane. In addition, the above hydrocarbon oil (A) may include pristane (molecular weight of about 268), hydrogenated farnesene, mineral oil with a molecular weight of 400 or less (liquid paraffin), hydrogenated polyisobutene with a molecular weight of 400 or less (hydrogenated polyisobutene), or hydrogenated polydecene with a mo
