Description

All-in-one cosmetic composition for cleansing with excellent moisturizing effect {COSMETIC COMPOSITION FOR CLEANSING SKIN WITH ALLINONE TYPE WITHOUT DRY FEELING}

The present invention relates to an all-in-one type cosmetic composition for cleansing with excellent moisturizing effect, and more particularly, to a cosmetic composition containing a natural polyglyceryl-based surfactant and a large amount of polyol, which is applied to dry hands to first make-up The present invention relates to a gel-type cleansing cosmetic composition that gently dissolves and then is washed with water for a second time to cleanly remove dirt from the skin and finish moistly.

In general, cleansing products that remove makeup ingredients are classified into cream, emulsion, liquid, and transparent gel types, and are classified into emulsion types, oil-based types, and water-based types, and are used in various ways according to their characteristics.

Representative emulsion types include cleansing lotions and creams, which are characterized by imparting a cleansing effect by blending a large amount of oil with a nonionic surfactant. The emulsion type has the advantage of excellent cleansing effect as the oil component accounts for 20 to 70% by weight, and excellent softness and massage effect when used. there is. In addition, skin irritation is caused by physical stimulation caused by the tissue off, and an oily feeling remains even after wiping with a tissue, so there is an inconvenience that water-based face washing must be performed using foam cleansing soap.

Oil-type cleansing oil contains almost 100% by weight of oil and is very effective in removing makeup, but similarly, there is a lot of oil remaining on the skin after use, so washing is not refreshing, and in the case of washable type, a large amount of surfactant is added May cause skin irritation. In addition, since all of the formulations presented above use a large amount of oil, the manufacturing cost is high.

In addition, the cleansing gel represented by the aqueous type includes a microemulsion gel type using a large amount of nonionic surfactant and a large amount of oil, and a detergent type cleansing product using an anionic surfactant. The microemulsion gel type contains a large amount of oil and surfactant, so it has excellent makeup cleansing power, but you have to endure a stiff feeling before the oil bursts out, and it may cause skin irritation due to the long rolling time. The downside is that you need to use an additional car cleanser. In addition, in the case of a cleansing gel type using an anionic surfactant, it has good spreadability and good washability in water, but has a disadvantage in that makeup cleansing power is weak.

In addition to the inconvenience of having to wash your face twice if you additionally use a second cleanser due to the oil residue, the lipid component is excessively washed during the double cleansing process, which can cause skin dryness.

In order to solve the above problems, Korean Patent Publication No. 2003-0051972 discloses a surfactant-free cleansing composition containing a small amount of oil, and Korean Patent Publication No. 2002-0037206 discloses oil-free oil-in-water makeup component removal. composition is proposed. However, as applied to the above patents, it is difficult to sufficiently remove makeup components with only a small amount of oil, and in the latter case, there is a limit to removing makeup components other than silicone. Also, like the products presented previously, there is a downside to having to double-cleanse due to oil residue, and excessive degreasing in the process can cause skin dryness.

Accordingly, the present inventors conducted research on a gel-type cleansing formulation that has excellent makeup cleansing power, light spreadability, excellent washability against water, and excellent moisturizing effect on the skin. A water-soluble polyglyceryl-type surfactant derived from natural substances was applied to increase the washability against water while increasing the makeup cleansing power, which was discussed as a disadvantage of the conventional products, and a cleansing gel type containing a large amount of moisturizer to further enhance the moisturizing effect. It is intended to provide a cosmetic composition.

The above object is an all-in-one cosmetic composition for cleansing comprising a polyglyceryl surfactant, a polyol and purified water, wherein the polyglyceryl surfactant is olive oil polyglyceryl-6 ester, argan oil polyglyceryl-6 ester, almond Oil polyglyceryl-6 ester, Argan oil polyglyceryl-4 ester, Almond oil polyglyceryl-4 ester, Babassu oil polyglyceryl-4 ester, Macadamia seed oil polyglyceryl-4 ester, Pomegranate seed oil poly In the group consisting of glyceryl-4 ester, linseed oil polyglyceryl-4 ester, pumpkin seed oil polyglyceryl-4 ester, safflower seed oil polyglyceryl-4 ester and horseradish seed oil polyglyceryl-4 ester at least one selected from the group consisting of glycerin, butylene glycol, dipropylene glycol, propanediol, methylpropanediol, propylene glycol, diglycerin and polyglycerin, It is achieved by an all-in-one cosmetic composition for cleansing.

Preferably, the cosmetic composition may include 1 to 20% by weight of a polyglyceryl-based surfactant and 10 to 50% by weight of a polyol based on the total weight of the cosmetic composition.

Also preferably, the cosmetic composition has a skin moisturizing effect.

The cosmetic composition for cleansing according to the present invention improves the oil residual feeling of the conventional primary cleanser (make-up dissolving type) and all-in-one cleansing with excellent moisturizing effect without using a secondary cleanser (fatty acid and detergent type). formulations can be implemented.

In the case of the conventional primary cleanser (make-up dissolving type), it contains a large amount of oil and a surfactant with a low HLB value, so makeup is well dissolved, but there is a case where double cleansing is necessary due to a severe oil residue. By using a polyglyceryl-based surfactant with a high HLB value while having a hydrophilic group, it has the advantage of dissolving makeup well and being washed off cleanly in water, so there is no need to double-wash, as well as preventing excessive degreasing due to double-washing and plant An excellent skin moisturizing effect can be imparted due to the influence of the derived polyglyceryl surfactant and moisturizer.
