Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a liquid soap composition containing a high-grade fat soap as a main component. More specifically, it relates to the physical properties of liquid soap, particularly liquid soap compositions containing high-grade fat soap as a main ingredient and having good usability such as foaming during use, foam persistence, and moist feeling after use. .

[Conventional technology and its problems]

Liquid soap is an anionic cleansing agent whose main ingredient is high-grade fatty acids (alkali metal salts of higher fatty acids), which are commonly used as the main ingredient in shampoos and body shampoos. Compared to anionic surfactants such as alkyl sulfates and alkyl ether sulfates, they have a lighter feel, are easier to rinse, and are much better at foam removal, but they have the disadvantage of being inferior in foaming and foam retention. For this reason, liquid ΔKEN has traditionally been used primarily as a cleanser for areas such as hands and face, and in addition to being easy to use, it foams and
The reality is that when it comes to detergents for paudies, where suds retention is an important factor, it is difficult to use liquid soap alone.

° As proof of this, if we look at the market for liquid body cleansers currently on the market by type, most of them contain anionic active agents such as alkyl sulfates and alkyl ether sulfates as their main ingredients, and in some cases they also contain A so-called simple type cleaning agent containing a combination of neutral anionic or amphoteric activators, or a combination of the same amount or more of the above anionic activators with high-grade fats, and in some cases, This is a so-called combination type wash that contains nonionic and amphoteric active agents. l) is either
There are almost no liquid detergents whose main ingredients are high-grade fats.

By the way, when we look at the characteristics of these commercially available liquid body cleansers, we find that the above-mentioned combination type and simple type, which have a high market share, contain high-grade fats such as dialkyl ether sulfate and alkyl sulfate as their main ingredients, and do not contain any harmful substances. Because it uses a large amount of anionic activator, it is certainly superior in terms of lathering and foam retention compared to high-grade fat-cleansing liquid body cleansers and regular bar soaps, but on the other hand, It cannot be denied that it is extremely inferior in terms of its properties, that is, its refreshing feeling after use, and its ability to remove bubbles.

On the other hand, the liquid body cleansers currently available on the market use high-grade fat ugly as the main ingredient.
Since no other activators are used,
In terms of usability, it has a light feel and very good foam removal, just like regular bar soap, but on the other hand, the combination type and simple soap do not have the same foaming properties and foam retention, which are important characteristics of body cleaners. It is inferior to other types of soap, and like regular bar soaps, it has the disadvantage that it tends to make your skin feel tight after use.

For these reasons, the reality is that there are currently no truly satisfactory body cleansers available on the market.

In recent years, the prevalence of showers has been increasing markedly, usage habits have improved markedly, and the market for liquid body cleansers is expected to expand further in the future, so solving the above problems is particularly important.

In view of the above-mentioned circumstances, the present inventors have created a product that, when used, is much superior in terms of lathering and foam persistence compared to conventional high-grade fat heavy soap type liquid body cleansers, in order to meet such demands.
Moreover, as a result of intensive efforts in research and development of a special composition of high-grade fatty heavy soap, the present invention has been completed.

[Means for solving problems]

That is, the present invention is a liquid soap composition whose main component is a high-fat heavy soap, which is characterized in that it contains one or more types selected from the following general formulas in an amount of 01 to && weight%. A soap composition.

The present invention will be explained in detail below.

The cationic polymer compounds represented by the above general formulas (A) l CB) l (C) used as essential ingredients in the present invention can be blended individually or in combination, and the blending amounts are as follows: 0.1 in the total amount of liquid soap composition
-aO weight %, preferably α2 - LO weight %.

If the amount is less than 0.01% by weight, the effect of improving the foaming and foam sustainability of the liquid soap composition will be small, and if the amount is more than 6.0% by weight, the usability will be undesirable with a slimy feeling. .

Introduction Although the mechanism of action in the composition of the present invention is not clear,
The specific cationic polymer compound in Doyo has a positive group in its molecule, creating a unique interaction with soap molecules, that is, a unique humplex compound, which serves the intended purpose of increasing the foam viscosity of liquid soap. It is estimated that a liquid soap composition that reaches .

Cationic polymer compounds other than the above general formulas (A), (E), (C), such as the following general formulas (D), (E), (F
) and (G) give a good moist feeling after use, but cannot provide good foaming and foam persistence, making it impossible to obtain a soap composition that achieves the desired purpose. Ta.

(The following is a blank space) The liquid soap composition of the present invention basically has the general formula (
The specific cationic polymer compounds represented by A), CB), and (C) are blended into a higher fat mass.

However, if the above-mentioned cationic compound is present in this liquid soap composition, the dissolution of the above-mentioned cationic compound is inhibited, and a liquid soap composition that achieves the desired purpose may not be obtained. In this case, add an appropriate amount of acyl-N-methyltaurine salt (
By incorporating A), (B) and (C) as a dispersing and dissolving aid, it is possible to obtain a liquid soap composition that achieves the desired properties.

In addition, as the above-mentioned dispersion and solubilization aid, in addition to N-methyltaurine salts, anionic activators such as alkyl sulfates, alkyl ether sulfates, N-alkaloylglutamic acid salts, and alkylsulfosuccinic acid salts were investigated. These had no effect.

The production of high-grade fat soap, which is to be the base of the liquid soap composition of the present invention, follows a known method.

Namely, animal fats and oils represented by beef tallow and mutton tallow, vegetable oils and fats represented by coconut oil, palm oil, palm kernel oil, soybean oil, olive oil, cottonseed oil, higher fatty acids (generally F-022), or resins. One or more acids are saponified or neutralized with an alkali such as caustic soda or caustic potash, and then diluted with an appropriate amount of water to obtain a liquid higher fat concentrate.

The blending amount of the high-grade fatty acid is 1 to 40% by weight, and tH,q <10 to 30% by weight, based on the total weight of the liquid soap composition, from the viewpoint of system stability and usability.

The liquid soap composition of the present invention includes the above (A), (B), (
In addition to C), the cationic polymer compound and the higher fatty acid, various compounding agents can be added as necessary.

For example, fats and oils such as lanolin, squalane, palmitic acid, and cetanol, moisturizers such as propylene glycol, 1.3 butylene glycol, glycerin, sorbitol, and PO adducts of diglycerin, sodium pyrrolidone carboxylate,
Conditioning agents such as pebutide can be blended.

Further, for the purpose of adjusting the viscosity, water-soluble polymers such as starch, natural gums, alginic soda, methylcellulose, polyvinyl alcohol, and inorganic salts can be blended.

In addition, other coconut fatty acid jetanolamide (1:1
type), foaming cleaning aids such as lauric acid jetanolamide, chelating agents such as edetic acid-3Nm and edetic acid-4Na, etc.
In addition, suitable amounts of coloring agents, fragrances, anti-inflammatory agents, bactericidal agents, pearl agents such as ethylene glycol distearate and fish phosphorus foil can be added.
