Description

Powdered cleanser composition for scrub effect with excellent moisturizing property

The present invention relates to an exfoliating powder detergent composition having excellent moisturizing properties. More particularly, the present invention relates to fatty acid carboxylates, anionic surfactants, amphoteric surfactants, moisturizing ingredients such as urea and extremely hardened palm oil, and urea and rice bran. It relates to a cleansing composition having an exfoliating effect made of an exfoliating component such as a powder.

In general, fatty acid carboxylate soaps are saponified with sodium hydroxide or potassium hydroxide using oils and fats of natural animals and plants such as tallow, palm oil, palm kernel oil and palm oil, or their decomposed fatty acids and fractionated distilled fatty acids. do. This fatty acid carboxylate soap has characteristics such as foaming and washing depending on the composition of palm oil or palm kernel oil. This is because of the lauric fatty acid saponification The higher the content of lauric fatty acid, the higher the solubility, so that bubbles are generated quickly, while the skin degreasing power is strong, so it is excellent in cleaning effect but may cause skin irritation.

In order to solve this method, fatty acid saponified ingredients such as lauric, myristic, palmitic, stearic, oleic and linoleic are used, a method of using a large amount of moisturizing ingredients, and superfatted soap is used. This can increase the smoothness and softness of the skin. It is possible to use fatty acids such as fats, oils and stearic acid as excess fats, which was already published in 1949 by Thomssen and McCutcheon in "Soap and Detergents "on pages 145-151.

In order to enhance the cleansing effect of the face wash, it has a creamy foam characteristic and has sufficient foam massage effect.It uses a certain amount of non-ion effective for oil pollution. By adjusting the ratio of fatty acid amido propyl betaine-based and non-ionic surfactants, the foam properties should be improved and oil pollution should be effectively removed.

Synthetic surfactants used in the preparation of hypoallergenic human cleansers include acyl taurate, sulfosuccinate, isethionate, glutamate, fatty alcohol sulfate and glyceryl ester sulfate. The system has been used the most. In addition, in the skin irritation, amino acid-based surfactants are known to have a very low irritation and excellent foaming and rinsing properties. In order to obtain such an effect, there is a disadvantage in that 60 to 70% by weight of the composition must be used.

Examples of applying acyl glutamate to human cleansers are described in US Pat. Nos. 5,693,604 and 5,387,372. There is a deviation from the powdered human cleanser composition as intended in the present invention.

In addition, two or more synthetic surfactant mixture compositions described in Japanese Patent Nos. 10,306,293, 10,237,494, and 06,025,695 as solid human cleanser compositions are not used as acyl glutamate system as an additional raw material, and greatly improve skin irritation. There are disadvantages that cannot be achieved and manufacturing cost increases when acyl glutamate and amino acid are used as main raw materials.

In general, in order to make a powder-type detergent using nonionic and amphoteric surfactants, since the general nonionic surfactant is in liquid form, it is necessary to use a very small amount or use an anti-caking agent separately. This does not sufficiently satisfy the above-mentioned cleaning conditions and has a limit in showing an excellent cleaning effect.

Increasing the amount of anionic surfactant having excellent cleaning power to increase the cleaning effect generally increases skin irritation, and mixing of a small amount of non-ion is insufficient to show an effective cleaning effect against oil pollution.

In order to prevent dryness and roughness of the skin, it is important to prepare keratinocytes and to form a natural moisturizing factor (NMF) in the keratinocytes and the sebaceous membrane covering the skin surface. Urea has been used in cosmetics and cleansing agents for the purpose of protecting keratin skin and showing moisturizing effects due to keratin dropping and moisturizing. In order to use urea in a liquid or creamy product, a technique for stabilizing urea to suppress ammonia odor must be accompanied, which is described in Japanese Patent Application Laid-Open No. 30509/1986. In addition, in order to use a fatty acid which is a sebum component as a component exhibiting a moisturizing effect, the formulation has to be liquid or creamy, which is far from the present invention.

In order to remove dead skin cells, mineral systems such as talc, organic systems such as grains, and proteolytic enzymes have been used. Inorganic systems can effectively remove dead skin cells due to physical phenomena, but they can also affect the soft dead skin cells and cause skin irritation. Cereals need technology to prevent corruption. If the amount of grain used increases, preservatives increase with it, which can cause skin irritation. In addition, proteolytic enzymes require a technique that prevents the rapid deterioration of the enzyme activity ability because the persistence and stabilization of the efficacy is implemented in the product composition. In general, proteolytic enzymes increase the production cost compared to inorganic or organic systems.

Accordingly, the present inventors have studied in view of the above points, and as a result, fatty acid carboxylate, anionic surfactant, amphoteric surfactant, moisturizing component such as urea component and extremely hardened palm oil, and exfoliating component such as urea component and rice bran powder It was confirmed that the composition consisting of the skin exfoliation effect and the skin moisturizing effect at the same time to complete the present invention.

SUMMARY OF THE INVENTION An object of the present invention is to provide a detergent composition in powder form having a significant improvement in skin irritation and simultaneously having a skin exfoliation effect and a skin moisturizing effect.

The fatty acid carboxylate soap may be selected from the group consisting of palmitic acid, stearic acid, and mixtures thereof.

The anionic surfactant may be selected from the group consisting of sodium cocoyl isethionate, disodium laurylsulfosuccinate, and mixtures thereof.

The extremely hardened palm oil as the moisturizing component may be a hardened oil obtained by curing a fatty acid of palm oil or palm kernel oil by a hydrogenation process.

In the present invention, the amphoteric surfactant may use lauro amido propyl betaine, which is very useful for maintaining the powder form in the present invention. The Lau amido propyl betaine includes Huntsman's Active LCP (trade name) sold in granule form.

The rice bran powder, which is an exfoliating component, may be selected from the sesame seeds of general grains.

The moisturizing and exfoliating components urea and extremely hardened palm oil may be used in a mixture with talc, respectively.

Hereinafter, the present invention will be described in detail.

The composition of the cleaning agent according to the present invention is characterized in that it contains 55.4 to 78.4 parts by weight of sodium stearade in fatty acid carboxylate soap powder.

In addition, the present invention uses the granule-type lauro amido betaine as an amphoteric surfactant to reduce the irritation of the anionic surfactant and creamy cream to exhibit a foam massage effect.

Extremely hardened palm oil and urea were used as moisturizing ingredients for powdered human body cleaners. To prevent caking, moisturizing ingredients and talc are mixed in a 1: 1 manner, and rice bran powder is processed to a level that passes 80 mesh. .

The degreasing phenomenon is improved by the added 3 to 6% by weight of humectants, and the urea and the rice bran powder, which is a natural fiber component, are rapidly deposited in water while being washed with water to allow smooth exfoliation cleaning.
