Description

Composition of water-soluble oily cleanser {Composition of Water Soluble Cleaning Cream}

The present invention relates to a creamy water-soluble oily cleanser composition, and more particularly, to a creamy water-soluble water solubility having excellent cleansing effect and skin safety by containing a water-soluble polymer thickener as a high-fat fatty acid soap and a stabilizing substance in a general oil-based cleanser. It relates to an oil-based cleanser composition.

In general, the cleansing agent includes a tissue-off type oil-based cleansing agent and a wash-off type water-based cleansing agent. Their main purpose is general cosmetics used for cleanliness of the skin. The face wash removes various wastes such as sweat, sebum, dust, and aged keratin, make-up residues and other contaminants on the surface of the skin to keep the skin moist and healthy, resulting in good makeup. If the above impurities remain on the skin, capillaries contract and blood circulation deteriorates and pores become clogged, which disrupts the oxygen and nutrient supply necessary for metabolism, making the skin unhealthy and worsening keratinization and acne. Or rashes or blemishes appear and lipid peroxides accumulate and cause premature aging.

Recently, with the development of technology, the face wash system has been able to select and use the face wash according to the skin type and degree of makeup. In other words, the water-type cleansing agent that gives a cool and fresh feeling is used when acne, oily skin, and makeup is light, and it is convenient in terms of use. Lotion-type cleansers are used when the skin is sensitive and wants to avoid irritation or when the skin is strongly irritated.It can remove skin impurities without any irritation.In case of normal skin or makeup, gel-type cleansers It also has a good facial cleansing effect than the water type and is good for use because it has no oily feeling.

In addition, the most commonly used facial cleanser is a cream type, which is used for people with neutral or dry skin or when the makeup is a little dark, has a soft texture and a massage effect.

On the other hand, foam cleansing, a cream-type aqueous cleanser, is used on all skins and is one of the most used facial cleansers to cleanse not only skin waste but also makeup.

These various types of face washes come out on the market according to their characteristics, but not all have advantages, but each has many problems with face washes. Water-type cleanser has a refreshing and cool advantage in use, but even a little make-up does not function as a cleanser, so you have to use oil-based cleanser again.In case of lotion type or cream type cleanser, the cleansing effect and massage effect are excellent. It may be unpleasant because of the oil remaining on the skin after use, and the foam cleansing, which is an aqueous cleanser, has a very good cleansing effect, but after use, the skin condition is excessively removed, so the skin is easily pulled out and wrinkles are formed. It has the disadvantage that it can ruin the healthy skin condition.

However, it is very difficult to manufacture a product having only the advantages of all the above-mentioned products, and many inventors have invented many face washes so far but are not satisfactory. The invention disclosed in US Pat. No. 39,944,506 is an application of a water-soluble abrasive to skin cleansing agents, which is invented for oily, keratinous and acne skin by simply using at least one derivative of sulfuric acid in a stable cream. In terms of aspect, it has not been improved compared to the previous technology, and US Pat. No. 4297374 also uses bananas and avocado fruit to enhance the cleansing function such as keratin improvement in dry skin, but it has not contributed substantially to the removal of oily contaminants. On the other hand, US Patent No. 5360824 contains a kind of scrub in the cleansing function to impart wrinkles improvement function, but the actual effect is unknown, US Patent No. 4535103 is a multi-phase cleansing composition using a water-soluble polymer in a general oil-based cleansing agent stable Invented the facial cleansing, but there was little improvement of the actual cleansing effect besides the visual effect. In addition, Korean Patent Application No. 96-74272 invented a face wash that can be used simultaneously as a wash-off and tissue-off type by applying high-alcohol, but lacking a dark makeup removal function due to its main function in exfoliation. In addition, the recent trends of the invention of the cleansing agent, many of the inventions (eg EP582246A, EP538764A, SU899541B, etc.) applied to the cleansing agent was synthesized most of the new surfactants, but the actual washing function is greatly reduced.

Accordingly, an object of the present invention is to provide a cream-type water-soluble oily cleanser composition with a fresh feeling that can be used for all skin types excellent in cleansing effects, skin safety, and ease of use.

The above object can be achieved by containing an appropriate amount of higher fatty acid soap and a water-soluble polymer thickener which is a stabilizing substance in a general oil-based cleanser.

The creamy water-soluble oily cleansing composition of the present invention having such a configuration includes 20 to 50 parts by weight of liquid paraffin, 1 to 10 parts by weight of a higher fatty acid soap, 0.05 to 0.50 parts by weight of a water-soluble polymer thickener, and 30 or less carbon atoms. It is characterized by including 3 to 15 parts by weight of condensation oil.

The higher fatty acid soap is a kind of anionic surfactant obtained by neutralizing a higher fatty acid having 8 to 22 carbon atoms with an alkali neutralizing agent such as sodium hydroxide, potassium hydroxide or triethanolamine, and examples of the water-soluble polymer thickener are carboxyvinyl polymer and hydride. Oxyethyl cellulose, carboxymethyl cellulose, and the like.

Examples of the ester condensation oil having 30 or less carbon atoms include isocetyl myristate, triisooctanoate, isononylisononanoate, and the like.

Hereinafter, the present invention will be described in detail.

In the present invention, 20 to 50 parts by weight of the liquid paraffin, which is a main cleansing function raw material of oil-soluble contaminants such as sebum, sweat, and makeup, is applied to 20 to 50 parts by weight, and the total carbon number is 30 or less for controlling the feeling and synergistic effect of face wash. 3 to 15 parts by weight of at least one of oils of the ester condensate, such as isocetyl myristate, triisooctanoate, isononyl isononanoate, and at least one of higher fatty acids having 8 to 22 carbon atoms. That is, 1-10 parts by weight of a higher fatty acid soap, which is a kind of anionic surfactant neutralized by mixing with at least one of sodium hydroxide and triethanolamine, and stabilized for the stability of use, carboxyvinyl polymer, hydroxyethyl cellulose, carboxymethyl 0.05-0.5 weight part of 1 or more types of water-soluble polymer thickeners, such as cellulose, are mix | blended and ethylene oxide is 10- It is a cream-type water-soluble oily cleanser completed by adding an appropriate amount of a general nonionic surfactant added with 60 moles, a moisturizer, an additive, a preservative, water, and the like.

In the present invention, the content of the liquid paraffin is 20 to 50 parts by weight, it is difficult to exert the face wash function at 20 parts by weight or less, and more than 50 parts by weight may be unpleasant to feel too oily when practically used and washable when washed with water. This is not desirable apart.

The use of ester condensed oil having a total carbon number of 30 or less uses 3 to 15 parts by weight.Ester condensed oil having 30 or more carbon atoms is not correct because of lack of freshness in terms of feeling. It is not preferable, and when it contains 15 weight part or more, it is unpreferable because it lacks the freshness and washability of a usability.

The content of an anionic surfactant soap made by neutralizing a higher fatty acid having 8 to 22 carbon atoms is 1 to 10 parts by weight. At 1 part by weight or less, the function as a water-soluble oily cleanser is not sufficient. The lack of oil remains on the skin, and the stability of the formulation is not particularly good at more than 10 parts by weight. The result of repeated application of anionic surfactants of higher fatty acid soaps was found to be good in the pH range of 7.0 to 8.5. In this area, we can see that it is safe. In addition, in the neutralization method of higher fatty acids, it was also found that the separation of fatty acids and neutralizing agents in the oil phase and the water phase, respectively, and the reaction upon emulsification after dissolution contribute to stability.

In addition, the water-soluble polymer thickener was applied to 0.05 ~ 0.5 parts by weight for the long-term stability of the present invention, but the contribution to the stability is less than 0.05 parts by weight and less than 0.5 parts by weight of the slippery and sticky phenomenon that is a disadvantage of the water-soluble polymer thickener. This cursor is not preferable in terms of usability.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples.
