Abstract

PURPOSE:To obtain the title composition having ample bubbling properties and high bubble tenacity and being especially excellent in creaminess of bubbles by using a specific glucose derivative. CONSTITUTION:The title composition is obtained from a glucose derivative (e.g. 6-O-lauroylglucose or methyl 6-O-undecyloylglucoside) of the given formula (wherein R<1> is 7-11C alkyl or alkenyl; and R<2> is H or 1-4C alkyl). By using the above glucose, the composition has ample bubbling properties and high bubbling tenacity and is especially excellent in creaminess of bubbles. The composition can be used in various forms such as a solid form as well a powder form, a flake, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides a cosmetic soap composition having improved use performance, more specifically, rich lathering properties.

The present invention relates to a cosmetic soap composition that has long-lasting foam and further improved foam creaminess.

[Conventional technology and its problems]

The general properties required for cosmetic soaps during use are:
In addition to having adequate cleaning power, it also produces rich foam, with a fine-grained, creamy foam that is stable. Naturally, since it is a skin cleansing agent, it is required to be milder.

As additives to improve creaminess, non-active agents such as anionic surfactants such as higher fatty acid salts and higher alcohols have traditionally been used. Currently, there is nothing that significantly improves the performance during use, so it is not used much at present.

[Problem of invention]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cosmetic soap composition with improved lather performance, particularly creaminess.

[Means to solve the problem]

The present inventors have conducted intensive research to solve the above problems, and as a result, a specific glucose derivative has mild properties and is suitable for soap compositions.

The present inventors have discovered that this method has an excellent effect on improving the creaminess of foam, and have completed the present invention.

That is, the present invention provides a cosmetic soap composition that contains a glucose derivative represented by the following general formula and has good foaming properties, good foam staying power, and particularly excellent foam creaminess.

In the above formula, R1 is an alkyl group or alkenyl group having 7 to 17 carbon atoms, and can be linear or branched. The alkenyl group may contain one or more double bonds. R2 is hydrogen or has 1 carbon number
-4 is an alkyl group.

Glucose derivatives used in the present invention include 6-0-acylglucose and its alkyl glucosides,
Specific examples include the following.

6-0-Caprylglucose 6-0-Caprylglucose 6-0-Undecylglucose 6-0-Lauroylglucose methyl 6-0-Caprylglucoside ethyl 6-0-Caprylglucoside methyl 6-0-Undecylglucoside methyl 6-0
-Ethyl lauroylglucoside 6-0-ethyl caprylglucoside 6-0-ethyl caprylglucoside 6-0 to ethyl undecylglucoside 6-0
-Lauroylglucosidepropyl 6-0-Caprylglucosideethyl 6-0-Caprylglucosidepropyl 6-0-Undecylglucosidepropyl 6
-0-Lauroylglucosidebutyl 6-0-Caprylglucosideethyl 6-0-Caprylglucosidebutyl 6-0-Undecylglucosidebutyl 6-0
-Lauroyl glucoside, etc.

These may be used alone or in combination of two or more.

These glucose derivatives are mild to the skin, do not reduce the foaming power of the soap, or tend to slightly improve it, and also have a satisfactory foam staying power, giving particularly fine-textured creamy foam. It has both effects.

In the glucose derivative represented by the general formula (1), when the number of carbon atoms in R1 is 12 or more, the effect of imparting creaminess becomes poor. On the other hand, even if the number of carbon atoms in R1 is 6 or less, the effect of imparting creaminess is not expressed.

The blending amount of the glucose derivative in the present invention is 0.5 to IO weight in the gold soap composition, more preferably 1.0 to IO weight.
It is in the range of 8% by weight. If it is less than 0.5% by weight, the effect will not be exhibited, and on the other hand, if it exceeds 10% by weight, further improvement in creaminess cannot be expected.

The soap base in the cosmetic soap composition of the present invention includes:
Various conventionally known fatty acid salts are used.

These soap bases include, for example, animal fats and oils such as beef tallow, pork fat, whale fat, and fish belly, and vegetable oils and fats such as coconut oil, palm oil, palm kernel oil, soybean oil, olive oil, and cottonseed oil. It can be produced by saponifying each of these alone or as a mixture with an alkali or the like, or by neutralizing various fatty acids with an alkali or the like.

The cosmetic soap composition of the present invention is produced by blending the above-mentioned glucose derivative into a soap base and homogenizing it according to a conventional method using a cross-lining method or a mechanical kneading method.

In addition to the above-mentioned ingredients, the soap composition of the present invention may optionally contain various additives as long as they do not impede the effects of the present invention. For example, as a surfactant, α-sulfo fatty acid ester, isethionate ester, alkylaryl sulfonic acid, alcohol sulfate ester, sulfate ester of alcohol ethoxylate,
Examples include olefin sulfonic acid, paraffin sulfonic acid, N-acylglutamic acid, salts of these esters and acids, alkyl betaines, alkyl sulfobetaines, and the like. In addition, as superfatting agents and skin protective agents that have a residual oil effect on the skin, for example, squalene, squalane, olefin oligomers, wax, petrolatum, other hydrocarbons such as petrolatum, various glycerides, sugar esters, lanolin, isopropyl chloride, etc. Fatty acid esters such as state, isopropyl palmitate, and isobutyl stearate, polyols such as glycerin, polyethylene glycol, and polypropylene glycol, ethoxylates of alcohols and fatty acids, silicones such as dimethyl silicone, and various other proteins and protein derivatives. , vitamins, etc. Other commonly used dyes, fragrances, etc. may also be blended.

In addition, the cosmetic soap composition of the present invention may contain anti-inflammatory agents such as allantoin and glycyrrhizinate, depending on the purpose of use.
It may contain conventional additives such as fungicides such as 2,4,4'-trichloro-2'-hydroxydiphenyl ether and 3,4,4'-trichlorocarbanilide.

〔Effect of the invention〕

The cosmetic soap composition of the present invention contains a specific glucose derivative, and thus has rich foaming properties and foam sustaining power, as well as particularly excellent foam creaminess. The cosmetic soap composition of the present invention can be used in various forms such as solid form, powder form, and flake form.
