Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved soap-based detergent composition, more specifically, the composition contains a higher fatty acid salt and a specific rosin derivative, exhibits creamy rich lathering, and provides a good feeling after washing. The present invention relates to a body soap-based cleansing composition.

Conventionally, various methods have been used to improve the foaming, foam properties, and feeling after washing of body soap-based cleansers. For example, in order to improve foaming and foam properties, attempts have been made to create a composite detergent by blending higher fatty acids, higher alcohols, etc., or blending anionic synthetic surfactants. However, when higher fatty acids are added, the color and odor deteriorate due to deterioration of the fats and oils, and when higher alcohols are added, the desired effect cannot be obtained with a small amount of addition, and foaming occurs when a large amount is added. Although the quality of the foam is improved, it has the disadvantage that foaming is significantly inhibited.

In addition, in the case of combination detergents containing anionic synthetic surfactants, the desired effect cannot be obtained with a small amount, and a certain degree of effect can be obtained with a large amount. However, there were problems with physical properties such as melting (slipping) and cracking, and liquid and paste forms had drawbacks such as phase separation.

On the other hand, methods to improve the feeling after washing include methods of blending polyols such as glycerin, methods of blending various oils and fats, and methods of blending cationic polymers, but none of these methods If a large amount is blended, the desired effect cannot be obtained because the amount remaining on the skin is small, and if a large amount is blended, although some effect can be obtained, when a bar soap is prepared using a polyol thread compound, the amount of water absorption is There is a disadvantage that the amount increases, causing swelling and dissolution, and when oils and fats or cationic polymers are used, there is a disadvantage that foaming is extremely reduced.

On the other hand, rosin and its raw material, pine resin, have long been known as inexpensive raw materials for soap.

That is, straight-chain fatty acid oils and fats derived from animals and plants and pine resin were saponified and salted out with a caustic alkali corresponding to the monoxide value to produce so-called soap. However, when soap is made by neutralizing untreated pine resin or rosin with caustic alkali, the color and odor inevitably deteriorate, and since the rosin is completely neutralized, it tends to foam and foam. The properties were poor, and the rosin was not well-adsorbed to the skin, so it did not wash well. Rosin is expressed by the following formula: abietic acid, last stric acid, neoabiedic acid, and isobimaric acid.The main components of rosin are abietic acid, parastric acid, neoabiedic acid, and isobimaric acid. Acids have conjugated double bonds and are extremely unstable against heat and light.
It was not suitable as a raw material for cosmetic soap.

The inventors of the present invention have been conducting intensive research in order to obtain a soap-based detergent that has good foaming properties, good foam properties, and a good feeling after washing, and also does not cause dissolution (slipping, cracking, phase separation, etc.) The present invention has been completed based on the discovery that an excellent soap-based detergent composition can be obtained by adding and blending a compound obtained by equalization, hydrogenation, or polymerization into a soap in the acid form.

Therefore, the present invention provides a soap comprising one or more types of alkali metal salts, organic amine salts, or ammonium salts of higher fatty acids having an average carbon number of 8 to 22, and to this soap!

Examples of the rosin that is a raw material for producing the acid-type rosin derivative of the present invention include gum rosin obtained from the resin of pine (Pinus genus plants), wood rosin obtained from pine roots, and tall oil rosin obtained from pine wood. .

The rosin derivative used in the present invention is prepared according to the formula below. For example, rosin is heated at a high temperature using a noble metal catalyst or a halogen catalyst, and then a mixture of dehydroabietic acid and dihydroabietic acid is prepared. Examples include homogenized rosin, dihydroabietic acid or tetrahydroabietic acid obtained by hydrogenating rosin at high temperature and high pressure in the presence of a noble metal catalyst, and polymerized rosin, which is a trimerized rosin obtained by treating rosin in the presence of an acidic catalyst. .

p (lower margin) Disproportionated hydrogenation and polymerization for preparing the rosin derivative of the present invention can both be carried out by conventional methods 1. If the rosin derivative is not in the acid form, mineral acids such as hydrochloric acid and sulfuric acid can be used. It can be converted to the acid form by treatment with

The fatty acid moiety of the alkali metal salt, organic amine salt, or ammonium salt (hereinafter simply referred to as "soap") of a higher fatty acid having an average carbon number of 8 to 22 used in the present invention is linear or branched, saturated or unsaturated. Among these, fatty acids and oleic acids having a linear saturated octane hydrocarbon group having 12 to 18 carbon atoms are particularly preferred.
In addition, examples of the alkali metal salts of soap include sodium salts and potassium salts, and examples of organic amine salts include monoethanolamine salts, jetanolamine salts, triethanolamine salts, and cyclohexylamine salts. Particularly preferred are salts, potassium salts, and triethanolamine salts.

The soap-based detergent composition of the present invention is prepared by a conventional method by blending soap with 0.1 to 50% by weight (hereinafter simply referred to as "ball") of an acid-type rosin derivative. These subcomponents may be incorporated into the soap-based cleaning composition depending on the possible dosage forms of the uninvented composition, i.e., solid, powder,
It varies depending on whether it is in granule, flake, chip, paste, or liquid form, but the total amount of subcomponents is 40 to 100% in powder or solid form, and 5 to 100% in liquid or paste form. Preferably it is 50%.

When the soap-based detergent composition of the present invention is made into a solid soap detergent composition, it can be solidified by any known solid detergent manufacturing method, regardless of whether it is a mechanical kneading method or a frame line method. , a primary l'a fatty acid having an average carbon number of 8 to 22 and an acid-type rosin derivative are mixed under heating, neutralized with an aqueous alkali solution corresponding to the neutralization value of the higher fatty acid, dried, and made into chips;
Next, known soap detergent components such as dyes and fragrances are added, uniformly kneaded, and extrusion molded to obtain a mechanically kneaded solid soap detergent. In addition, a mechanically kneaded solid soap detergent can be made by adding a finely powdered acid rosin derivative to soap chips together with known soap detergent ingredients such as pigments and fragrances, kneading the mixture uniformly, and extrusion molding. I can do it. Furthermore, a solid soap detergent can be obtained by mixing an acid type rosin derivative with additives such as a coloring matter and fragrance into a molten soap, cooling and solidifying the mixture, cutting it, drying and molding it. All of the solid soap detergents obtained in this way have good lathering and foam feel.
In addition, it has an excellent usability, and has excellent safety, stability, and solid physical properties.

In addition, when using liquid or paste soap detergents,
