Abstract

The present invention relates to an oil-type cosmetic composition which has a thick slip sense and excellent moisture evaporation barrier properties, and can be easily used. The oil-type cosmetic composition is made of a composition having very excellent moisture evaporation barrier properties according to a skin constitution of a baby. Meanwhile, conventional products use mineral oil having high flowability. Accordingly, when a parent applies the oil to a baby by using his/her hand, the oil flows and thus the parent feels inconvenient. To this end, ease in using a formulation is improved by using an oil gelling agent in the present invention. In addition, due to a thick slip sense, a parent can be satisfied by feeling that a formulation is thickly and sufficiently applied to a baby, and gloss makes the skin of the baby look moist after the application of the formulation.

Description

Oil type cosmetic composition {OIL-TYPE COSMETIC COMPOSITION}

The present invention relates to an oil-type cosmetic composition, and more particularly, to an oil-type cosmetic composition having a thick slip feeling, a high moisture barrier property and easy to use.

In general, babies tend to dry very easily, unlike adults' skin. The reason is as described in L.S. Telofski-The Infant Skin Barrier: Can We Preserve, Protect, and Enhance the Barrier; Hindawi Publishing Corporation Dermatology Research and Practice; 2012], the skin of babies and adults show differences in skin function due to differences in their compositional and skin structural aspects. It is characterized by low content of natural moisturizing factors in the aspect of dermatological composition and thin skin thickness in terms of skin structure. As a result, the baby's skin is characterized by the fact that the skin of the baby has a lot of moisture due to the formation of water in the body, unlike the adult skin, but the water loss is higher than that of the adult due to immaturity of the skin barrier

Nevertheless, the vast majority of baby products are mostly products that appeal to a low content of natural moisturizing factors, which are skin constituents, rather than skin structural aspects in terms of marketing. Accordingly, there are many commercially available emulsion formulations for supplying moisturizers with formulations containing commercial moisturizing ingredients such as ceramide, lecithin, or the like, which are natural moisturizing factors, or lamellar liquid crystals that can carry moisture. Also, in the oil composition, organic vegetable oils may be used for the natural ingredient concept for sensitive baby skin.

However, due to the nature of the baby skin that dries easily after using common commercial emulsion products, the baby mother tends to finish with the baby oil in the finishing step after applying the emulsion type product to be used.

Korean Patent Laid-Open No. 10-2016-0077757 discloses an oil-dispersible cosmetic composition containing a high-concentration powder.

The present invention focuses on the structural characteristics of the baby's skin to form a skin barrier barrier having a sufficient moisture content in the skin but can prevent water loss for the baby's skin in which moisture loss easily occurs.

In addition, general commercial baby oils have very high flow properties, and the user is the mother of the baby. However, since the user is the baby who is lying down, the oil is put in the hand and the palm is directed downward . As a result, usability such as flowing oil is low.

The present invention relates to an oil-based cosmetic composition comprising glyceryl behenate / eicosadioate and meadowfoam seed oil.

Specifically, the cosmetic composition comprises 2.0 to 4.0% by weight of glyceryl behenate / eicosadioate and 25 to 30% by weight of meadowfoam seed oil based on the total weight of the cosmetic composition.

Preferably, the cosmetic composition has a viscosity of 4,000 cps to 8,000 cps.

Preferably, the cosmetic composition is used in a beautifying product.

The cosmetic composition according to the present invention is excellent in the effect of blocking moisture evaporation and is easy to use. When using the cosmetic composition according to the present invention, it is possible to feel a thick slip feeling due to the thickness feeling of the formulation and the low frictional force, and it is possible to visually confirm the moisturizing effect of the skin by providing sufficient shine on the skin after use.

In addition, the cosmetic composition according to the present invention has spreadability and viscosity of about lotion according to the degree of gelation, and can be picked with a finger or the like like a cream formulation, so that it is easy to use.
