Description

Cosmetic soap composition {Toilet soap composition}

The present invention relates to a cosmetic soap composition, and more specifically, a combination soap or synthetic detergent bar (Syndet bar) containing 5 to 70% of a surfactant as a main detergent to impart a moisturizing power. The present invention relates to a cosmetic soap composition which improves the foaming ability of) and suppresses the occurrence of sweat on the surface of soap and improves the clouding phenomenon in which a surfactant appears white on the surface of colored soap.

In general, soap is a mixed soap containing a fatty acid soap obtained by decomposing fats or oils or fats with an alkali and a fatty acid soap as a main cleaning component, and containing 5 to 30% of a surfactant as an auxiliary cleaning component. ) And a synthetic surfactant soap (Syndet bar, hereinafter referred to as a complex soap) using a surfactant as a main cleaning ingredient and a general soap as an auxiliary cleaning ingredient or binder. Fatty acid soaps are generally easy to manufacture, inexpensive, and hard, so they are not easily softened or frayed.However, the aqueous solution shows alkali, so if you use it frequently, it removes excessive sebum in the skin. There is a weakness that can soften the skin, causing it to dry and lose its elasticity, making the skin rough or irritating. On the other hand, mixed soap or complex soap has the advantage that the liquidity of the aqueous solution is weak acid, neutral, weak alkali, so it is less irritating to the skin and excellent moisturizing effect.

Surfactants used in mixed or complex soaps include acyl isethionate, alkyl sulfates, alkyl sulfosuccinates, alkyl glyceryl ether sulfonates, straight chain alkyl benzene sulfonates, acyl taurates, alkyl sulfoacetates, acyl sacosines Acetates, acyl glutamate, alkyl ether sulfates, monoglyceride sulfonates and the like. Such mixed or complex soaps are used in an amount of 1 to 30 parts by weight of a binder or plasticizer such as sodium isethionate, anhydrous manganese, salt, starch, etc. to impart physical properties and bond strength.

Mixed or complex soaps using the above surfactants as the main cleaning base generally have less stimulation and superior moisturizing and feel compared to fatty acid-based makeup soaps, but high solubility surfactants are used as the main or auxiliary cleaners. It has high solubility in water such as inorganic salt and starch used as a binder, and absorbs water or hydrates after use or storage.In severe cases, water drops in the surface of the soap by absorbing water from the air under high temperature and high humidity. Condensed sweating occurs (Sweating) occurs, especially in the case of mixed soap has a disadvantage that occurs white cloudiness is applied to the surface of the soap as a surfactant during storage.

These sweating and clouding phenomena are not only good appearance, but also deteriorate the feeling of use when reused, and the soap is easily worn and is not economically desirable. In addition, like fatty acid soaps, soaps may sometimes crack when stored for a long time or after use.

Soap manufacturers have increased their interest in incorporating various additives into cosmetic soaps to address these problems.

For example, US Pat. No. 3,951,842 uses a polymer of linoleic acid and sodium sulfate or salt to prevent the retreat of complex soaps, and US Pat. No. 4,007,125 uses sodium alkanesulfonates having 12 to 14 carbon atoms. Improved. However, the addition of these ingredients to some extent to improve the physical properties of the soap, but the degree of foaming of the soap is lowered, improving the sweating or preventing the turbidity of the surface of the soap is insignificant.

The present invention is to solve the problems of the prior art as described above, polyethylene glycol having a molecular weight of 2,000 to 40,000 in a mixing soap or a combination soap containing 5 to 70% of a surfactant as a main cleaner. Containing polypropylene glycol dimethicone improves the sweating phenomenon, suppresses the occurrence of turbidity on the surface of the soap, improves the workability, and improves the bubble reduction problem caused by the inorganic salts used to improve the physical properties To provide a cosmetic soap composition.

The present invention provides a mixed or complex soap using 5 to 70% of a surfactant as a main or auxiliary cleaner, and contains 0.1 to 10% by weight of polyethylene glycol / polypropylene glycol dimethicone having a molecular weight of 2,000 to 40,000 represented by the formula (1). Provided is a makeup soap composition.

   [Formula 1]

Wherein the number of moles of dimethicone x is 400 to 600, y is 1 to 2, the number of moles of polyethylene m is 0 to 30, the number of moles of polypropylene n is 0 to 30, and Z is hydrogen or methyl Group (hereinafter referred to as "PEG / PPG dimethicone").

Hereinafter, the present invention will be described in detail.

According to the present invention, it improves the foaming power of a combination soap or a synthetic surfactant soap containing 5 to 70% of a surfactant or a synthetic surfactant soap, suppresses the occurrence of sweat on the surface of the soap, and creates a cloudy whiteness on the surface of the soap. As a method for improving the phenomenon, the mixing soap or the composite soap which is conventionally prepared contains 0.1 to 10% by weight of polyethylene glycol / polypropylene glycol dimethicone having a molecular weight of 2000 to 40,000, It can improve the cloudiness and improve the bubble level.

The PEG / PPG dimethicone used in the present invention may be dimethicone of PEG-8 to 30, dimethicone of PPG-6 to 30, dimethicone of PEG-0 to 25 / PPG-0 to 25, and m + At least 8 is suitable for n.

More specifically, mixed soaps and mixed soaps have a higher affinity for water than general toilet soaps, and inorganic salts such as salt, anhydrous manganese, and sodium isethionate, which are used as physical property improvers, absorb water. Under high humidity and high humidity conditions, the sweating phenomenon that water droplets form on the surface of the soap is likely to occur. After moving together to the surface, it may be dried to cause a cloudy appearance on the surface. In order to improve the sweating phenomenon, there is a method of adding a large amount of oil-soluble oil component to change the surface of the soap into hydrophobic, and using an additive such as propylene glycol to suppress evaporation of internal moisture. However, this method has a disadvantage in that the effect is not sure and using a lot of oil, the physical properties of the soap, workability is lowered and the foaming power is lowered when used. In addition, the use of polyols such as propylene glycol has a disadvantage in that the fragrance is not emitted well and workability is also reduced.

The amount of PEG / PPG dimethicone used in the present invention is suitably from 0.1 to 10% by weight. If the content is less than 0.1% by weight, the effect is difficult to fully exhibit. If the content is more than 10% by weight, the workability is lowered and the soap is submerged, which is not suitable for mass production.

According to the present invention, in the polyethylene glycol / polypropylene glycol dimethicone, when the polyethylene glycol dimethicone is used, the added mole number of polyethylene is 8 to 30 dimethicone, and when the polypropylene glycol dimethicone is used, the added mole number of the polypropylene is 6 to 30 dimethicone When using polyethyleneglycol / polypropylene methicone, it is preferable to use dimethicone whose sum of the added mole number of polyethylene and the added mole number of polypropylene is 8-50.

(2) Sweating measurement

Since bathrooms and bathrooms that use soap are usually hot and humid, water vapor forms on the surface of the soap even when not directly in contact with water, and it grows and becomes water droplets. If this condition is repeated and continued, it may cause softness and surface roughness. This series of phenomena is called sweating. Sweating was first evaluated by maintaining the soap in a constant temperature and humidity (30 ℃, absolute humidity 80%) conditions for 24 hours and then the degree and size of water vapor or water droplets formed on the soap surface by giving a score based on the criteria shown in Table 1.
