Description

Facial cleansing composition {Facial Cleansing Composition}

The present invention relates to a face wash composition. More specifically, the present invention is a face wash composition of a cream to paste formulation by using a monoglyceride sulfonate having 7 to 21 carbon atoms and fatty acid soap as the main detergent, and containing a polyhydric alcohol and an ethylene glycol fatty acid ester having 7 to 21 carbon atoms. It is characterized in that the excellent usability and cleaning power and formulation stability.

The most basic step in facial care is skin cleansing, or facial cleansing. Oily contaminants such as excess sebum, cosmetics and make-up products, especially residues of waterproofing products, accumulate in the skin, which can cause pores by clogging pores, so daily skin cleansing is very important. Cleansing products, ie face washes, are essential for good detergency and skin protection against a variety of skin contamination.

Various face washes are known for this purpose, and among them, a product of the type that can be rinsed out of the foam has excellent cleaning power and can provide a refreshing feeling. Such cleansing products are largely divided into semi-solid (cream to paste) type, liquid type, solid soap, and the like, among which the most common type is semi-solid type (cream to paste). Face creams on creams and pastes have many advantages, such as being easier to form dense and richer foams than liquid type or solid soaps, but do not spill products when used. Has been made.

Korean Patent No. 2000-0019529 describes a fatty acid soap type cream / paste cleansing composition characterized by excellent temperature stability and creamy bubbles, smooth and rich feeling, and excellent rinsing properties. It contains alkaline fatty acid soap as a main ingredient, and has good foaming, rinsing feeling and cleansing power, but has disadvantages such as excessive skin pulling due to skin irritation due to excessive degreasing and skin adsorption of metal soap. The weakly acidic cleansing composition has the advantage of less skin pulling feeling, which is a disadvantage of these fatty acid soaps, and relatively low skin irritation due to weakly acidic liquids, but has weak foam, less rinsing feel and freshness than fatty acid soaps, especially rinsing. It has the disadvantage of leaving a slippery feeling after. In order to improve these two types of solutions, a certain ratio of fatty acid soaps and synthetic surfactants have been used to solve the skin pulling feelings of ordinary fatty acid soaps and to improve the difficulty of rinsing.

Korean Patent No. 1999-0082012 discloses a body soap composition prepared by mixing a fatty acid soap and a polyoxyethylene alkyl ether sulfate in a specific ratio in various formulations such as solid, semi-solid, and liquid types, but it has a foaming capability compared to fatty acid soap. And the good quality of the foam was found to have a limit of falling. Therefore, it is still necessary to develop a cleansing agent having excellent foam and rinsing quality and excellent skin texture and skin moisturizing power after cleansing.

The present invention provides a stable facial cleanser composition of a cream to paste formulation using the main cleaning component monoglyceride sulfonate and fatty acid soap, polyhydric alcohol. It has a low irritation to the skin and has excellent feeling of use such as foam and rinsing, and has excellent characteristics such as skin texture and skin moisturizing power after washing.

The present invention contains 0.1 to 40.0% by weight of monoglyceride sulfonate of Formula 1, 10.0 to 40.0% by weight of fatty acid soap, 5.0 to 35.0% by weight of polyhydric alcohol and 1.0 to 5.0% by weight of ethylene glycol fatty acid ester of Formula 2 The present invention relates to a facial cleanser composition.

[Formula 1]

(2)

The monoglyceride sulfonate used in the present invention is the same as in Chemical Formula 1, wherein R is alkyl having 7 to 21 carbon atoms and M is sodium, potassium, triethanol amine or ammonia. In this case, in order to impart better foaming properties while giving lower skin irritation, R is most preferably alkyl having 11 to 17 carbon atoms, especially 11 to 13 alkyl, and M is sodium or potassium. The content of said monoglyceride sulfonate exhibits a favorable feeling of use and stability at 0.1 to 40.0% by weight, in particular 10.0 to 15.0% by weight.

The fatty acid soap used in the present invention uses 10.0 to 40.0% by weight, preferably 20 to 30% by weight of one or more selected from fatty acids having 12 to 18 carbon atoms.

In the present invention, the polyhydric alcohol and ethylene glycol fatty acid ester are used in parallel to improve the low temperature stability and high temperature stability of the formulation. The polyhydric alcohol used at this time is 5.0 to 35.0% by weight, preferably 15.0 to 27.0% by weight, based on one or more selected from glycerin, propylene glycol, butylene glycol, dipropylene glycol, polyethylene glycol, and sorbitol.

Ethylene glycol fatty acid esters used in the present invention may be used in the formula (2) is an alkyl having 7 to 21 carbon atoms, n is 1 to 2 1.0 to 5.0% by weight, most preferably alkyl having 15 to 17 carbon atoms Most preferred is 1.0 to 2.5% by weight, with n being 2. For example, the ethylene glycol fatty acid ester is preferably at least one selected from ethylene glycol monostearate and ethylene glycol distearate.

Hereinafter, the present invention will be described in detail.                     

The present invention has the disadvantages of the conventional face washes, that is, the problem causing the skin pulling feeling of the face wash mainly composed of fatty acid soap, and the rinse without rinsing well of the face wash mainly contains a surfactant is a feeling of slippery skin In order to solve the remaining points, such as deterioration of the foam quality of the cleansing agent of the mixed cleansing ingredients, after the research, the following surprising facts were found and completed based on the following.

In other words, by using both anionic surfactant monoglyceride sulfonate and fatty acid soap as a main cleaning component of the face wash and using polyhydric alcohol and ethylene glycol fatty acid ester to improve low temperature and high temperature stability, Usability, moisturizing power and detergency are maintained excellently.

In addition, the facial cleanser composition of the present invention can be used by mixing with the auxiliary cleaning agent within the range of 0.1 to 20.0% by weight of the synthetic surfactant usually used in the facial cleanser within a range that does not impair the effects of the present invention.

<Test Example 3> Moisturizing test

Moisturizing power was evaluated by measuring the moisture retention rate. The compositions of Examples 1 and 2 and Comparative Examples 3 and 4 were diluted with distilled water to form a 1% aqueous solution, 5 ml of this aqueous solution was rubbed for 5 minutes at a 5 cm X 5 cm area inside the arm, and then waited for 30 seconds and then flowed for 10 seconds. Washed in water. After washing twice at 3 hour intervals per day, water retention was measured after 30 minutes for each soap. Skicon 200 was used as a measuring device for water retention, and the test was conducted in a constant temperature and humidity room at 25 ° C. and 50% relative humidity. The moisture retention was calculated according to Equation 1 below. The greater the moisture retention rate, the better the moisture retention. The moisturizing test was conducted on 30 men and women in their 20s and 40s.

[Equation 1]

Moisture retention rate (%) = ((Retention before washing-retention after washing) / retention before washing) X 100

The results measured according to the method are listed in Table 4 below.
