Description

Cosmetic soap composition {Toilet Soap Composition}

The present invention relates to a cosmetic soap composition comprising a cosmetic soap material, a moisturizing component, and a surfactant. More specifically, by adding a hydrogenation process and an optional free fatty acid to increase hardness while maintaining the excellent foaming power, bubble stability, and cleaning effect of palm oil or palm kernel oil fatty acid soap powder, it is possible to prevent a decrease in productivity during manufacturing. In addition, the present invention relates to a cosmetic soap composition in which the moisturizing property is increased by adding a moisturizing component and a surfactant and there is no cracking phenomenon.

In general, soap is soaped with sodium hydroxide (Potassium Hydroxide), using natural copper, vegetable oils such as tallow, palm oil, palm kernel oil, palm oil, vegetable fats or their decomposed fatty acids, and fractionated distilled fatty acids. The mixing ratio of the saponified component of the saponified component of palm kernel oil or palm oil is 60 to 90% and 10 to 40% of the soap, using a suitable amount of fragrances and additives were prepared by extrusion and molding.

The higher the saponified oil of palm kernel oil or palm oil or the more composition of the lauric acid soap having 12 carbon atoms, the easier the generation of bubbles and the better the touch. Colgate-Palm Olive, Inc., US Pat. No. 4,767,560 improved the bubble properties by distilling the palm oil to partially saponify to increase the foaming capacity, and in particular to foam easily in cold water. In addition, palm oil or stearic acid was added as superfatted to show a mild effect on hand washing.

Soap made of palm oil has a low concentration (Titer), which leads to a significant decrease in productivity due to difficulty in extrusion and molding during soap manufacturing. Therefore, the content of soap-containing moisture or a high concentration of stearic acid (Titer) should be used to improve hardness. There was a problem. In order to solve this problem, there was a problem in that a process of increasing the efficiency of mixing by using a roll mill in the process of drying the soap and drying the soap for a long time in the process is required.

The use of superfatted soaps can promote the formation of dense creamy foam and increase the smoothness and softness of the skin. The use of overfat in soaps can also increase the hardness. Fats such as fats, oils, and stearic acid can be used as excess fats, as described by Soap and Detergents (P. 145-151) and Luis Spitz, co-authored by Thomssen and McCutcheon in 1949. Soap Technology For The 1990's (P 217-218).

In the manufacture of general cosmetic soap, when soap is manufactured using only soap soap produced by saponification process by adding sodium hydroxide to palm kernel oil and palm oil, the hardness is low, which improves the mechanical equipment such as vacuum state during extrusion and cooling conditions of molding. Or there is a problem in that the production efficiency is lowered even if some adjustments are made in the production of solid soap.

In addition, the soap produced by this production has a problem that the phenomenon that the soap tissue is swelled and swells due to the high low-temperature solubility during repeated use often occurs.

Soap material that saponifies saturated fatty acids without double or more carbon-to-carbon bond among fatty acids has few fatty acids with double bonds such as oleic acid and linoleic acid which give softness of soap tissue. There was a problem. Therefore, it is necessary to change counter ions instead of sodium ions (for example, potassium ions) to improve water solubility, improve water retention, and to suppress excessive evaporation of moisture during drying. There was a problem that needs to be improved.

In addition, there is a method of using the anti-cracking agent to increase the softness of the soap tissue by using 3% or more of polyhydric alcohols such as glycerin or triglyceride type to improve the cracking phenomenon, but the foaming force is reduced and the soap withdraws There was a problem that the losing phenomenon occurs. When soap content is 13% before and after the use of liquid additives, the general soap has a problem that only less than 5% can be added, including fragrance.

In order to solve the above problems, the present invention, compared to the general cosmetic soap, while maintaining excellent foaming power, bubble stability and cleaning effect does not occur in the production loss during manufacturing, there is no cracking phenomenon cosmetics with increased moisture retention It is an object to provide a soap composition.

The above and other objects of the present invention can be achieved by the present invention described below.

The present invention to achieve the above object,

75 to 92% by weight of the palm soap or palm kernel oil fatty acid soap powder cured by the hydrogenation process and free fatty acid, 5 to 10% by weight of moisturizing component, and 1 to 20% by weight of surfactant. It provides a makeup soap composition.

The palm oil fatty acid or palm kernel oil fatty acid soap powder is characterized in that the content of lauric acid having 12 carbon atoms of 45 to 60% by weight, the content of fatty acids having a double bond does not exceed 1 to 2% by weight.

The free fatty acid may be selected from the group consisting of palm oil fatty acid, myristic acid, stearic acid, and mixtures thereof.

The moisturizing component may be a liquid emollient of oils and polyhydric alcohols.

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

Hereinafter, the present invention will be described in detail.

The composition of the soap base according to the present invention is characterized in that the saponification by hydrogenated hardening of 75 to 92% by weight palm oil or palm kernel oil.

The content of lauric acid having 12 carbon atoms of the soap palm oil fatty acid and palm kernel oil fatty acid is 45 to 60% by weight, and the content of fatty acids having a double bond such as oleic acid and linoleic acid does not exceed 1 to 2% by weight.

The present invention converts fatty acids having a carbon-to-carbon double bond such as oleic acid and linoleic acid into single bond stearic acid using a fatty acid which has been hydrogenated to palm oil and palm kernel oil, and the concentration of fatty acid is hydrogen. It is higher than without addition and hardness increases.

Although the composition of fatty acids is slightly different depending on the origin of palm oil and palm kernel oil, palm oil has 5 to 8%, palm kernel oil has 13 to 16% of fatty acids having double carbon-to-carbon double bonds such as oleic acid and linoleic acid. Is switched.

In the preparation of soap bases, fatty acid is used to increase the hardness by using tallow, palm oil as the fat, or 5 to 15% by weight of myristic acid or stearic acid as a single fatty acid. Softness can be increased.

Sodium Cocoyl Isethionate, Disodium Lauryl Sulfosuccinate , And 1 to 20% by weight of a mixture of these surfactants is mixed to convert the liquid additive into a cream phase to prepare and add Conditioning Pre-Mix to the same amount of liquid emulsifier of the same amount of oil and polyalcohols. ) Extrusion, molding, and overall production efficiency were increased when comparing the method of direct input with the ingredients and Humidectants and the production efficiency.

In addition, the present invention uses the sodium Cocoyl Isethionate (Sodium Cocoyl Isethionate), Disodium Lauryl Sulfosuccinate as a surfactant is less irritant, such as sodium cocoate, sodium palm kernelate Soap prepared by mixing with a fatty acid carboxylate-based soap is effective to remove the oil contamination and easy to prepare a uniform cream when mixed with liquid oils and polyhydric alcohols.

The liquid emulent and humectants of 5 to 10% by weight of oil and polyalcohols added in this way improve strong degreasing and pulling, and excellent moisturizing effect and cleansing effect. to be.

Hereinafter, the present invention will be described in more detail with reference to the following examples, but the scope of the present invention is not limited to the examples.
