Description

The composition of cleansing tissue containing polyglyceryl-10 stearate or polyglyceryl-10 laurate

The present invention is a polyglyceryl-10 stearate (Polyglyceryl-10 stearate) or polyglyceryl-10 laurate (Polyglyceryl-10 laurate) used as a substitute for a surfactant of the polyethylene glycol type that has recently emerged as a topic of safety. It relates to a cleansing tissue (beauty wipes) composition containing.

The wet tissue is composed of non-woven fabric and liquid, and is prepared by absorbing the liquid in the non-woven fabric. Therefore, wet tissues are widely used as tissues, towels, and towels due to the convenience of not having to wet the water separately. Wet wipes are used in various places because liquid can be released and are easy to perform various cleaning functions. In particular, in recent years, for the purpose of wiping off makeup cosmetics used on the face, a wipes named Cleansing Tissue or Beauty Wipes have been developed and used. Since the purpose of the cleansing tissue is to wipe the makeup products on the face, it should contain an oil component that can wipe the makeup products differently from ordinary wipes. The core of the wipes is that the amount of liquid absorbed by the non-woven fabric and the liquid remain stable. In the case of a cleansing wipe, the oil must be well mixed with the water. It is also important to make sure that it contains enough oil to wipe off makeup cosmetics. Surfactants are required to mix water and oil well. Currently, most of the wipes use PEG (polyethylene glycol)-based surfactants.

The outstanding surfactant activity of PEG (PEG) has the advantage of excellent emulsifying ability to mix water and oil well and low price, but at the same time, it has the disadvantage of being excessively absorbed by the skin when applied to the skin. In addition, PEG is made by the addition reaction of ethylene oxide, and has the problem of toxicity if ethylene oxide, a starting material used in manufacturing PEG, is not completely removed. In addition, 1,4-dioxane (1,4-Dioxane) is produced as a side-reactant in the manufacturing process, and 1,4-dioxane is also a compounding prohibited material that cannot be used in cosmetics with ethylene oxide. EWG grade of ethylene oxide is 10, and 1,4-dioxane is 8 grade. Currently, there is no regulation on the specific content limit for 1,4-dioxane produced as a by-product derived from AGE, but consumers' anxiety about the AGE-based surfactant used in wet wipes is increasing.

For this reason, attempts have been made to actively replace the PEG-based surfactant. Alternative surfactants are sugar derived surfactants such as alkyl glucosides. Alkyl glucosides are compounds in which sugars, such as glucose, and fatty alcohols are connected by ether bonding through a condensation reaction. The sugar portion of glucose exhibits hydrophilicity, and the fatty acid alcohol portion exhibits lipophilicity, and thus has surfactant activity. Another alternative is a polyglyceryl ester compound. The polyglyceryl portion exhibits hydrophilicity and the ester portion exhibits lipophilicity, thereby having interfacial activity. Polyglyceryl-10 stearate was used as a surfactant to prepare W/O/W multiple emulsions (J. Soc. Cosmet. Scientists Korea, 2014, 40, 237), and polyglyceryl ester compounds were ceramides. There is an example used in the composition for external application for skin containing (Patent Registration, 10-1198275). However, it has not been used in wet wipes to date.

Republic of Korea Patent Registration No. 10-1198275

Accordingly, the present inventors intend to manufacture a cosmetic wipe using a surfactant that does not contain a page for the purpose of replacing the conventional PEG (PEG) surfactant (Tween 80, Polysorbate 80) used in the wet tissue formulation.

Dimethicone was used as an oil for removing makeup cosmetics. When a wet tissue formulation was prepared using dimethicone directly, it did not mix well with water even when a large amount of surfactant was used. In order to solve this problem, dimethicone was mixed with glycerin, lecithin, and purified water and used through a high pressure emulsification process using a microfluidizer.

The dimethicone that has been subjected to high pressure emulsification was used, and various surfactants containing no sebum were used to confirm the emulsification stability of the wet tissue formulation. Polysorbate 80 was used as a control. As a result of emulsification stability, it was confirmed that two surfactants, polyglyceryl 10-stearate and polyglyceryl 10-laurate, exhibited an emulsion stability equal to or higher than that of polyisolate 80.

Accordingly, it is an object of the present invention to provide a composition of a cleansing tissue (beauty wipes) containing polyglyceryl 10-stearate or polyglyceryl 10-laurate.

The cleansing tissue composition containing polyglyceryl-10 stearate according to the present invention uses dimethicone pretreated with high pressure emulsification using a microfluidizer as an oil, and contains various natural extracts including glycerin as a water-soluble part. It is characterized by.

And the cosmetic composition comprising a polyglyceryl 10-laurate according to the present invention as a surfactant uses dimethicone pretreated with high pressure emulsification using a microfluidizer as an oil, and various water-soluble parts including glycerin It is characterized by containing a natural extract.

Cleansing tissues containing polyglyceryl-10 stearate or polyglyceryl-10 laurate (beauty wipes) used as a substitute for polyethylene glycol surfactants It relates to a composition, to provide a cleansing tissue that does not have sebum stability problems.

1 is a view showing a layer separation visual evaluation in Test Example 2.

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

Cleansing tissues that do not contain PEG surfactants can be obtained in two steps:

Step 1: Process of high pressure emulsification by mixing dimethicone with glycerin, lecithin, purified water using a microfluidizer, a high pressure emulsifier,

25% dimethicone (25%) is mixed with 60% glycerin, 10% purified water, and 5% lecithin as a surfactant, followed by high pressure emulsification with a microfluidizer 3 times to dimethicone A mixed solution was prepared. The silicone oil used in the present invention is not limited to dimethicone. Silicone oils such as Dimethiconol, Triphenylmethicone, Cyclopentasiloxane, and Cyclohexasiloxane may also be used.

Step 2: The process of manufacturing a beauty wipe using a dimethicone that has been subjected to a high pressure emulsification pretreatment in step 1 and a surfactant that does not contain sebum

In the second step, a formulation that can be used for cosmetic wipes using the dimethicone mixture prepared in step 1 was prepared. In order to be used as a cleansing tissue to remove makeup cosmetics, 1%-2% silicone oil is required. If less than 1% of silicone oil is used, it is not easy to remove makeup cosmetics, and in the case of 2% or more, a large amount of silicone oil remains on the skin after use. It is preferred to contain 1.5% silicone oil in the cleaning tissue. To make a cosmetic wet tissue emulsion containing 1.5% of dimethicone, a formulation was prepared using 5% of the dimethicone mixture prepared in step 1.

In order to replace the polysorbate 80, which is the sebum surfactant, emulsification stability was measured in comparison with polysorbate 80 using various surfactants. The content of the polysorbate used in the experiment for comparison was 0.02%. However, the concentration of the surfactant used is not limited to 0.02% concentration. 0.02% is the minimum concentration and higher concentrations (0.02%-10%) can also be used.

As a result of comparing the emulsification stability by conducting the experiment at a concentration of 0.02%, it was confirmed that the two surfactants of polyglyceryl 10-stearate and polyglyceryl 10-laurate exhibited an emulsion stability equal to or higher than that of polyisolate 80.

Since the wet tissue formulation prepared by the above-described manufacturing method stably mixes dimethicone, an oil capable of removing makeup cosmetics, without using a sebum surfactant, it is safer to the consumer than a wipe using a sebum surfactant. Tissue can be provided.

Hereinafter, the cleaning method using the surfactant (polyglyceryl 10-stearate and polyglyceryl 10-laurate) that does not contain the sebum surfactant according to the present invention through test examples and examples is more specifically As described.
