Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to cleaning products such as shampoos, cleansing foams, body shampoos, and soaps.

[Prior Art] Since the above-mentioned cleaning agent is intended for the human body, it is required to have a pleasant feeling during and after use, in addition to "cleaning" which is the original function of the cleaning agent. The term "favorable feeling in use" as used herein means that the hair and skin feel smooth during and after use, and that the hair and skin do not experience excessive sensations such as squeaks, dryness, or tightness.

For this reason, various substances have conventionally been blended into cleaning materials as usability-enhancing agents. For example, adding a small amount of oil, such as liquid paraffin, to give a smooth feeling when using the product, or adding a humectant, such as glycerin, to give a moist feel. has been done.

[Problems to be solved by the invention] However, when these conventionally used substances are mixed, the cleaning function may be excessively reduced depending on the product system, foaming may be extremely deteriorated, or Furthermore, in many cases, it causes a significant decrease in viscosity in a product system that is supposed to maintain a predetermined viscosity, and has a large effect on other physical properties, so improvements have been desired.

The inventors of the present invention have conducted repeated studies to overcome the above-mentioned drawbacks, and to develop a δ-paper engraving that has the original cleaning function while maintaining a favorable feeling of use.As a result, the inventors have found that by incorporating pullulan, the objective can be achieved. This discovery led to the present invention.

[Means for Solving the Problems] That is, the present invention is a cleaning agent characterized by containing pullulan.

The present invention will be explained in detail below.

The pullulan used in the present invention is Aureobas id
Maltotriose is a water-soluble sticky polysaccharide produced outside the cells of P. lumpullulans, and maltotriose is α-L6-
It is known that it is a linear α-glucan that has been repeatedly polymerized by 1ucosi-dic bend.

The blending amount of pullulan is from 0.01 to the total amount of the cleaning agent of the present invention.
The amount is 20% by weight, preferably 0.5 to 5% by weight.

If the blending amount is less than 0.01% by weight, it is difficult to impart a desired feeling of use, and if the blending amount exceeds 20% by weight, it is difficult due to the solubility of pullulan.

The surfactant used as a cleaning active ingredient in the cleaning agent of the present invention is an anionic, nonionic, or amphoteric surfactant. Examples of the anionic surfactant include I'O[E alkyl ether carboxylate, higher fatty acid salt, N-acylamino acid salt alkyl sulfonate, alkylaryl sulfonate, α-olefin sulfonate, acyl isethionate, Alkyl sulfosuccinates, acyl taurine salts, alkyl sulfates, POE alkyl sulfates, alkyl phosphates, etc. are used, and as nonionic surfactants,
Alkylolamides, POE-POP block type nonionic surfactants, sucrose fatty acid esters, etc. are used, and as amphoteric surfactants, carboxyhetaines, sulfobetaines, imidacillin derivatives, etc. are used. One or more of these may be arbitrarily selected.

In the present invention, in addition to pullulan, ingredients and additives commonly used in detergents may be blended as necessary.
It is also possible to use a usability improver that has been used in the past. . Namely, higher alcohols, lanolin,
Lanolin derivatives, oily ingredients such as liquid paraffin, humectants such as propylene glycol, glycerin, and polyethylene glycol, water-soluble polymer substances (including anionic, nonionic, and cationic substances), drugs such as vitamins, and preservatives. , bactericidal agents such as zinc pyrithione, pH adjusters, ultraviolet absorbers, animal and plant extracts such as lecithin and gelatin or their derivatives, pigments, fragrances, and fine polymer powders such as nylon and polyethylene. Naturally, these must be used within a qualitative and quantitative range that does not interfere with the effects of the present invention.

[Example] Next, an example of the present invention will be shown. In addition, the compounding amount is weight%.

Example 1 Shampoo■ Polyoxyethylene lauryl ether sulfate l-reethanolamine (40%) 30.0■ Polyoxyethylene lauryl ether sulfate soda (30%)

(2) was dissolved with heating and stirring, and kept at 70°C, which was used as the aqueous phase. Gradually add the water phase to the oil phase and stir thoroughly. After adding ■ to this, it was cooled to 30℃ with a heat exchanger,
I got a cleansing foam. This cleansing foam had a smooth foam and had an excellent feeling of use with no stiffness or dryness even after use.

[Effects of the Invention] The cleaning agent of the present invention is a cleaning agent that imparts a smooth feel to hair and skin during and after use without any deterioration in cleaning function. In addition, since the aqueous solution of pullulan has a moderate viscosity, by changing its concentration,
In liquid product systems, it is also possible to adjust the viscosity to your preference.
