Description

Transparent soap composition

The present invention relates to a transparent soap composition for human cleansing. More specifically, the present invention relates to a transparent soap composition formulated using an anionic surfactant sulfosuccinate, a nonionic surfactant, sodium soap, potassium soap, and the like. Containing parts by weight, it is easy to swell when used and does not recede, and transparency has the advantage of lasting to the end.

Looking at the theory of the mechanism for the present invention, as described in the case of ordinary soap (SOAPS JG Kane, University Bombay 18p-22p; SOAP MANUFACTRE J. ADVIDSOHN. USA 50p-54p), Therefore, the phase change proceeds differently. Specifically, it changes to α, β, ω, and Δ phase. In general, the soap used in the β, ω phase determines the degree of swelling, the hardness, and the rate of dissolution in water according to the two phases. The phase generally used is β phase.

In the β phase and the ω phase, the soap content appears at 60% or more, and the crystal structure is described as the crystal fiber phase proposed in the existing patents (Patent Publications 90-4684 and 86-2070), but the present invention specifically approaches the interface theory. When soap is a kind of surfactant, micelles are formed above the CMC concentration, and when the concentration is gradually increased, the concentration is increased in the lamellar structure of the cylindrical structure and it is known to have a plate-like giant structure.

In general, the soap structure used is a plate-shaped giant structure, in which the arrangement of the hydrophilic group and the lipophilic group is formed in the same direction, and the arrangement of the hydrophilic group is formed densely, and thus the soap is opaque in general soap.

Transparent soap production principle in the present invention is similar to the soap structure and by using a surfactant having a large size of the head portion of the hydrophilic group by forming a three-dimensionalization of the lipophilic tail portion by preventing the scattering of light by arranging the non-ionic polyol Due to the method of manufacturing the clearing soap, it is a new manufacturing method that is fundamentally different from the existing unstructured and transparent soap manufacturing by simply combining the raw materials.

In addition, as an advantage of the present invention, when used, the hardness is the same as that of general soap, and the manufacturing method is also simple, so that it can be converted into mass production, so that the transparent soap can be popularized.

US Patent No. 2,820,768 has been prepared using sodium soap and triethanolamine soap and neutralized with fatty acid, such as coconut, tallow, palm fatty acid and castor oil. The product is manufactured and sold as a product called Netrogena. However, this product has excellent feeling, but the swelling degree of water of triethanolamine soap is rapidly progressed, and it is manufactured by using caster oil having high hydroxyl and unsaturated degree to improve transparency and disadvantages of drying while using it. After a certain period of time has a disadvantage of discoloration to brown due to the immunization reaction of triethanolamine. For this reason the color was commercialized in brown.

In another manufacturing method, Japanese Patent No. 81-11680, based on fatty acid soap, uses excess alcohols for neutralization reaction, and heat-mixes a transparent agent such as sugar, glycerin, sorbitol, propylene glycol and polyhydric alcohols, and a solvent such as ethanol and water. After cooling and solidifying them, they are dried for several weeks, followed by volatilization of accompaniment and ethanol to produce them. If the product is given a gloss on the surface, it has excellent transparency and endless transparency in use, but needs to secure process period and space. Due to the high labor costs, manufacturing costs are rising.

U.S. Patent No. 3,969,259 uses Igasan DP300, a trochloroic acid having an antibacterial component, in the case of simply adding an antimicrobial component to an existing transparent soap method and in the case of U.S. Patent 85-4493786, sodium soap 25% -55% anion, zwitterionic surfactant Although 10% -40% and 15% -65% polyhydric alcohols are used, the above methods have been invented by simply changing a few compositions in the above-mentioned contents, and the transparent soap has a large amount of triethanol in unsaturated fatty acids containing hydroxyl groups. It is divided into a method of forming amorphous by using amine and forming a polyol in a solid, and an alcohol method using sodium soap and excess ethanol and polysaccharides. This is an invention included in the United States Patent Nos. 2,820,768 and Japanese Patent Nos. 81-116800 from a macro perspective.

As described above, the present invention relates to potassium soap, alkyl sulfosuccinate, alkyl sulfate-type surfactant, and three-dimensional space, which can make a hydrophilic group array structure in a three-dimensional space while maintaining a planar three-dimensional bubble array in a soap phase. Polyhydric alcohols, D-glucose, and triethanol amine, which form transparency, are arranged in the soap crystal structure to show transparency, and sodium and potassium soap components improve the hardness, so when used, hardness is the same as general opaque soaps, and in the manufacturing process Since no maturation period is required, automation is possible, and manufacturing costs also provide a transparent soap composition having the advantage of being able to mass-produce to a general soap level.

The present invention is described in detail as follows.

Sodium soap is a mixed fatty acid with a carbon composition of 10 to 18 fatty acids. It uses palm fatty acid and coconut or palm nucleus fatty acid, which is usually 65% to 75% of palm fatty acid and 25% to 35% of coconut or palm nucleic acid. 40 to 60 parts by weight of sodium soap and 1 to 10 parts by weight of potassium soap having a greater water solubility than sodium soap in the soap molecule are added. At this time, the fatty acid of potassium soap is neutralized using palm stearic acid. This results in a molecular arrangement that increases the transparency of the soap and increases the transparency. In addition, alkyl sulfosuccinate and alkyl sulfate are also added in an amount of 1 to 10 parts by weight to solubilize the molecular arrangement and the system to improve transparency.

1 to 20 parts by weight of glycerin, 1 to 20 parts by weight of polyethylene glycol, 1 to 20 parts by weight of D-glucose, and 1 to 20 parts by weight of triethanolamine are used as a component for forming transparency on the crystal structure of the soap structure and the surfactant. In order to increase the solubility of sodium soap and potassium soap in the process, 1 to 20 parts by weight of monohydric alcohol is used.

The alkyl sulfosuccinate used in the transparent soap of the present invention is represented by the formula (1), the alkyl sulfate is represented by the formula (2).

NaSO ₃ CHCOONa

Wherein R ₁ is a fatty acid of an alkyl, alkene or alkane group.

R ₁ OSO ₃ Na

Wherein R ₁ is a fatty acid of an alkyl, alkene or alkane group.

As shown in the above formula, the water-soluble moiety is larger than sodium soap.

The transparent soap composition according to the present invention has excellent transparency and good solubility in water because the surfactants of Formulas 1 and 2 are stereoscopically co-ordinated in an array having a stereotype structure of micelles, lamellas, and platelets formed in the crystal theory of soap. The polyol and the saccharide and the like of the structure in which the size of the molecule can be arranged between the oil-soluble groups in the three-dimensional structure are added to form the transparency.

The structure of the general soap and the structure of the potassium soap are shown in the formulas (3) and (4), respectively.
