Description

Solid Body Cleanser Composition for Cosmetic Removal

The present invention relates to a solid body cleanser composition for removing makeup. More specifically, the emollient component of the hydrophilic lipophilic balance (hereinafter referred to as HLB) about 13-16, which facilitates the removal of the lipophilic raw material from the skin and has good affinity with water. It relates to a solid body cleanser composition for removing cosmetics prepared by mixing with a solid surfactant and a fatty acid.

In general, cosmetics form a moisture protective film on the stratum corneum to prevent evaporation of moisture. Since these ingredients have a lipophilic property, they are strongly adsorbed to the skin and are not easily removed by ordinary soap or detergent from water. . Therefore, in order to remove these cosmetics, using a cleansing cream, the cosmetic ingredients adsorbed on the skin are desorbed from the skin and wiped with a makeup paper, and the remaining cosmetic ingredients are solubilized with a surfactant such as cleansing foam and facial cleanser and washed with water. There is the hassle of double face-to-face.

When applying basic cosmetics (e.g. skin, lotion, cream, etc.) or cosmetics (e.g., makeup base, skin cover, lipstick, powdered powder, etc.) to the skin, it is very strongly adsorbed on the skin and difficult to remove These are straight chain hydrocarbons of about 10-20 carbon atoms, straight chain fatty alcohols, fatty acid esters, etc. having high lipophilic properties between HLB 3-7. The components of the stratum corneum, the outermost layer of skin, are composed of lipophilic substances that differentiate through keratinocytes, which have lost their nuclei, and lipids that fill the gaps between them. Keratinocytes are filled with a relatively dense matrix and low-density fine fibres, which are long proteins of amino acids. Lipid components present between keratinocytes are composed of ceramide, fatty acid, cholesterol, sterols and wax esters. Therefore, the stratum corneum of the epidermis has a strong lipophilic character and strong adsorption of cosmetics. Cleansing creams are used to remove these cosmetics from the skin.

The general cleansing cream used for such a purpose is prepared by mixing a commercially available raw material having a similar HLB value with the skin adsorption components of cosmetics and ingredients suitable for skin protection. When the cleansing cream is applied to the skin, the cosmetic ingredients, etc. adsorbed on the skin are desorbed from the skin because the proportion of the cleansing cream that is more lipophilic than the skin is increased. However, since the cleansing cream itself has a greater affinity for skin than water, it needs to be wiped with a make-up paper, and the remaining cream ingredient needs to be washed once again with a detergent containing a surfactant. As such, there are drawbacks to the hassle and inconvenience of double face washing, excessive time consumption, high cost, and inconsistency of the place of cleansing cream and cleansing foam.

Therefore, the present inventors exert the function of desorption of the skin adsorption components of cosmetics to improve the inconvenience of the double face wash, and as a result of careful research to find a component having excellent affinity with water, HLB 13-16 degree of emollient components are I found it useful for my needs. In other words, the present inventors cleansing cream when mixing the emollient component of HLB 13-16, which has a skin desorption effect on the lipophilic raw material of cosmetics, and a solid surfactant and fatty acid having excellent solubilization ability to the lipophilic component. The present invention has been found to be able to include the function of and the cleansing foam in a single product.

Hereinafter, the present invention will be described in more detail.

The solid human cleanser composition for removing makeup according to the present invention is useful for skin desorption of cosmetics, and has a function of 1-20% by weight of an emulsifying component of HLB 13-16, which is excellent in affinity with water, for sulfate or sulfonate. 50-80% by weight of a mixture of sodium cocoyl isethionate, disodium laurylsulfosuccinate, sodium lauryl sulfate, and fatty acids 5-30 of C ₁₂ -C ₁₈ for increasing hardness and imparting a moisturizing effect. It is prepared by mixing the weight percent homogeneously, and the solid human cleanser prepared in this way is excellent in removing makeup even when used under the same conditions as general soap, so that cleansing cream and cleansing foam can be washed clean without inconvenience. In addition, the present invention exhibits a much better skin-cosmetic effect compared to conventional cleaning agents by containing an emollient component.

The solid human cleanser composition of the present invention contains components used in a conventional human cleanser in addition to the above-described characteristic ingredients.

Solid human cleanser of the present invention is prepared as follows.

That is, the fatty acid is dissolved at a temperature of 60-70 ° C and then mixed slowly with a propeller to uniformly mix the surfactant, liquid emollient, emulsifier. After solidification by passing through a cooling tunnel (cooling tunnel) through a roll mill (roll mill) process to be crushed evenly. It is prepared by dry blending the titanium dioxide, discoloration inhibitor, pigment, flavor, etc., as a brightening agent, homogeneously mixing in a kneader, and then introducing the same into a floater and solidifying the same.

The solid human cleanser composition of the present invention prepared as described above comprises 50-80% by weight of a surfactant mixture such as sodium cocoyl isethionate, disodium lauryl sulfosuccinate, sodium lauryl sulfate and the like based on the total weight of the composition. Useful for skin desorption and excellent affinity with water, 1-20% by weight of HLB 13-16 emollient for removing cosmetics, and 5-30 weight of fatty acid of C ₁₂ -C ₁₈ for increasing hardness and giving moisturizing effect It is manufactured by mixing the% uniformly, and even when used under the same conditions as general soap, it has excellent makeup removal ability. After applying cleansing cream, cleansing is possible without the inconvenience of applying double cleansing foam. This results in a much better skin care effect than conventional cleaners.

In particular, PEG-60-hydrogenated castor oil (PEG), which is a compound in which an average of 60 moles of polyethylene glycol is added to PEG-7-glycerylcocoate and hydrogenated castor oil as an emollient component Emollients added hydrophilic properties by ethylene oxide, such as -60-hydrogenated castoroil and PEG-60-glyceryl isostearate, have superior effects compared to other raw materials. Have

In addition, the surfactant used in the present invention may be used by mixing one or two or more selected from sodium cocoyl isethionate, disodium lauryl sulfosuccinate and sodium lauryl sulfate. Preferably the mixing ratio is sodium cocoyl isethionate / disodium lauryl sulfosuccinate / sodium lauryl sulfate = 70/20/10.

Conventional solid human cleansers are prepared with a surfactant as a main component. These surfactant components include sodium tallowate, sodium cocoate, sodium cocoylisethionate and di Sodium laurylsulfosuccinate, sodium lauroylglutamate, sodium laurylsulfate, and the like.

However, sodium cocoyl isethionate, disodium lauryl sulfosuccinate, sodium lauryl sulfate having a functional group of sulfate or sulfonate as a functional group used in the present invention is relatively low threshold. It has a micelle concentration value, so it shows much better solubilization ability than sodium lauroyl glutamate derived from fatty acid carboxylate-based sodium tallowate, sodium cocoate and amino acid. Nate, disodium lauryl sulfosuccinate, sodium lauryl sulphate, etc. when used in combination when used alone lowers the critical micelle concentration value shows increased solubilization ability.

In the above, solubilization refers to a process in which a material insoluble in a solvent is dissolved into a thermodynamically stable isotropic solution by reducing the thermodynamic activity of the entire system through a reversible reaction with a surfactant, and the efficiency of solubilization is the critical micelle concentration of the selected surfactant. It depends heavily on the critical micelle concentration.
