Description

Detergent composition containing high content of oil {Body cleaning composition containing high content of oil}

The present invention relates to a cleaning composition containing a high oil content, and more specifically, to a cleaning composition containing alkylene glycol alkylate, having good stability even when containing a large amount of oil, and excellent makeup cleansing effect.

In general, when a detergent composition containing an ionic surfactant contains a large amount of oil (~50%), problems arise such as a decrease in viscosity or separation of oil, which reduces the stability of the product.

Accordingly, attempts have been made to stabilize a detergent composition containing an ionic surfactant by using an excessive amount of acrylate-based polymer, for example, carbopol, or by using a Gemini type surfactant in a fixed ratio, but acrylate When using a polymer-based polymer, the feeling of use was not good when rinsing due to the unique filmy feel, and when using a Gemini-type surfactant, formulation was possible only at a certain ratio, which resulted in high manufacturing costs and poor quality. There was this.

As a result of diligent efforts to solve the problems of the prior art, the present inventors confirmed that the composition can be stabilized by using alkylene glycol alkylate as an emulsion stabilizer in a detergent composition containing a large amount of oil, and proposed the present invention. Completed.

The purpose of the present invention is to provide a detergent composition that has good stability and excellent makeup cleansing effect even when it contains a large amount of oil.

In order to achieve the above object, the present invention provides an alkylene glycol alkylate represented by the following Formula 1 or Formula 2; and 1 to 50% by weight of oil based on the total weight of the composition.

In the above formula, n is 1 and m is 6 to 24.

In the above formula, n is 1 and m is 6 to 24.

Alkylene glycol alkylate represented by Formula 1 or Formula 2 is a compound that can be obtained from the esterification reaction of alkylene glycol and fatty acid, and is used as a lipophilic emulsifier and emulsion stabilizer in the present invention. ) can play a role. Alkylene glycol alkylate is located between the surfactants when forming micelles, and expands the relatively small lipophilic tail portion compared to the relatively large hydrophilic head portion, thereby creating oil with a high molecular weight. Oil can be stabilized by changing it to an emulsified structure that can capture .

Preferably, in Formula 1 or Formula 2, m may be 8 to 20, and more preferably, in Formula 1 or Formula 2, m may be 10 to 16.

Preferably, the alkylene glycol alkylate is propylene glycol laurate, propylene glycol myristate, propylene glycol stearate, butylene glycol. Butylene Glycol Laurate, Propylene Glycol Behenate, Propylene Glycol Caprylate, Butylene Glycol Behenate, Butylene Glycol It may be Butylene Glycol Myristate, Butylene Glycol Palmitate, Butylene Glycol Stearate, etc. More preferably, the alkylene glycol alkylate is propylene glycol laurate, propylene glycol myristate, propylene glycol stearate, butyl It may be Butylene Glycol Laurate.

Alkylene glycol alkylate may be included in an amount of 0.5 to 50% by weight, preferably 1 to 30% by weight, and more preferably 3 to 20% by weight, based on the total weight of the composition. If the content of alkylene glycol alkylate is less than 0.5% by weight, the physical properties and stability of the composition may be poor, and if it is more than 50% by weight, the quality of the product may be reduced due to poor feeling of use.

The detergent composition of the present invention may further include a surfactant.

Preferably, the surfactant may be an anionic surfactant, an amphoteric surfactant, a nonionic surfactant, or a mixture thereof.

Examples of anionic surfactants include acyllauryl sulfate, sodium cocoyl isethionate, sodium lauryl sulfate, ammonium lauryl sulfate, polyoxyethylene sodium lauryl sulfate, polyoxyethylene ammonium lauryl sulfate, and sodium acyl glycinate. , potassium acyl glycinate, sodium acyl glutamate, potassium acyl glutamate, etc., but is not limited thereto.

Examples of amphoteric surfactants include cocamidopropyl betaine, lauramidopropyl betaine, lauryl betaine, coco-betaine, myristyl betaine, cocodimethylcarboxymethylbetaine, lauryldimethylcarboxymethylbetaine, Disodium cocoamphodiacetate, lauryl hydroxysulsteine, etc. may be mentioned, but are not limited thereto.

Examples of nonionic surfactants include Caprylyl/Capryl Glucoside, Decyl Glucoside, Coco-Glucoside, Lauryl Glucoside, etc., commonly known as alkyl glucosides. Examples include, but are not limited to.

The surfactant may be used in an amount of 0.5 to 50% by weight, preferably 3 to 40% by weight, and more preferably 7 to 30% by weight, based on the total weight of the composition. If the surfactant content is less than 0.5% by weight, the surface tension of the bubbles is lowered, making it difficult to form bubbles, and the bubbles disappear easily, so it is difficult to expect abundant foaming power, and the contaminant removal power is poor. If it exceeds 50% by weight, Although it has good foaming power, it has the disadvantage of not being good at rinsing, leaving a strong slippery feeling on the skin, and not giving a good overall feeling of use.

In the present invention, the oil is a common oil used for moisturizing purposes, and vegetable oil or liquid paraffin can be used. Examples of vegetable oils include, but are not limited to, soy bean oil, macadamia seed oil, manuka oil, sunflower oil, olive oil, and tea tree oil.

The oil is included in the detergent composition at 1 to 50% by weight, preferably at 3 to 45% by weight, and even more preferably at 10 to 40% by weight, based on the total weight of the composition.

If the oil content is less than 1% by weight, the physical properties and stability of the product are improved, but it has little effect on skin irritation, skin flexibility, and skin moisturizing power that the present invention aims to achieve. If the oil content exceeds 50% by weight, it has an excellent moisturizing effect, but the formulation It affects the physical properties and stability of , and has a defoaming effect, which tends to significantly reduce the foaming force.

The detergent of the present invention may additionally contain a preservative. There are naturally occurring preservatives, but commonly used preservatives are synthetic raw materials, such as parabenzoate, sodium benzoate, imidazolidinyl urea, phenoxyethanol, and methyl chloride, which are commonly known as parabens. Isothiazolinone, methylisothiazolinone, chlorophenecin, etc., but are not limited thereto.

In addition, the detergent composition of the present invention may contain substances used in conventional cosmetics or detergents, such as colorants, flavoring agents, disinfectants, antioxidants, metal ion sequestrants, moisturizers, etc., in addition to the above-mentioned active ingredients.

The detergent composition of the present invention can be used for makeup cleansing purposes and not only exhibits an excellent makeup cleansing effect but also exhibits high stability.
