Liquid crystal emulsifying composition for mask pack, manufacturing method thereof and mask pack containing the same {Liquid Crystal Emulsion Composition for Mask Pack, Method for Preparing Same, and Mask Pack Containing Same}

The present invention relates to a liquid crystal emulsion composition for a mask pack, a method for manufacturing the same, and a mask pack containing the same, and more specifically, it is capable of stably encapsulating a reticulated structure of a porous fiber, thereby improving skin efficacy components such as improving wrinkles and whitening on the mask pack. It relates to a liquid crystal emulsion composition for a mask pack containing a liquid crystal emulsion capable of stably carrying a, a manufacturing method thereof and a mask pack containing the same.

Recently, various types of cosmetics are sold in the market, but among them, the mask pack is a product type that many consumers are constantly looking for due to its ease of use and excellent moisturizing effect even with a single use. Various types of mask packs have been developed, such as fiber-impregnated masks, hydrogel masks, and biocellulose masks, but the fiber-impregnated mask packs with a lot of makeup impregnated with a fiber supporter due to skin adhesion and an instant moisturizing surface It is getting attention.

Mask packs in which various types of fiber supports, such as cotton fibers and natural-derived long fibers, have been developed in accordance with consumer demand for products in the form of cosmetic water impregnated with such fiber supports. However, this type of mask pack in the form of a fiber support has only limitations in the types of fibers, and most of the fiber support is impregnated with lotion, and there is a limitation limited to the moisturizing effect of an instant hydration type.

In order to overcome this, a mask pack representing high functionality was proposed, but only the skin efficacy component was added to the cosmetic, and it was difficult to expect a distinct efficacy effect when actually used.

On the other hand, a liquid crystal (liquid crystal) is a semi-crystalline phase that exhibits an intermediate characteristic between the structural properties of a liquid and a regular structural property of a solid, and has relatively less molecular mobility than a liquid by regular alignment between molecules. For this reason, it has properties such as scattering of light and properties such as crystallinity.

Recently, it has been found that liquid crystals may be formed by ceramide, cetyl alcohol, stearyl alcohol, cholesterol, and nonionic surfactants, and may contribute to improving stability of useful skin materials. However, in the case of such a liquid crystal, when it contains a skin-soluble substance having a high oxidizing property such as retinol, the ability to prevent oxidation of the substance is poor, and there are many problems in using it as a product.

Liquid crystal emulsion is a liquid crystal that embodies a lamellar structure similar to the intercellular lipid of the stratum corneum of the skin with an emulsification method.It has excellent moisturizing power compared to general emulsions, and can deliver skin active ingredients to the skin well, thus providing serum and eye cream. It is applied to high functional basic cosmetic products.

As an example of applying such a liquid crystal emulsifier to a mask pack, Korean Patent Application Publication No. 10-2006-0018493 provided a semi-transparent gel mask cosmetic composition using a liquid crystal emulsification method, and as a recent patent, the Republic of Korea Patent Application Publication No. 10 -2017-0125211 describes a hydrogel mask pack composition with excellent water retention.
