Description

Detailed Description of the Invention 3. Detailed Description of the Invention The present invention relates to a liquid detergent composition used as a shampoo composition or the like.

BACKGROUND OF THE INVENTION In recent years, there has been a demand for detergents for hair, body, etc. that not only foam during cleaning but also have a creamy foam feel. In addition, it is necessary for hands and skin to be smooth and dry after washing, and there is a strong demand for hair cleansers such as shampoos to leave hair smooth and dry to the touch after washing.

Conventionally, water-soluble polymers such as hydroxyethyl cellulose are blended into liquid detergent compositions to improve the creamy feel of the foam, but this method does not provide a sufficient feel after washing, resulting in a sticky feeling after washing. ” or “stickiness” may remain, making it difficult to obtain a smooth and dry feel.

It is an object of the present invention to provide a liquid detergent composition that produces fine, creamy foam during washing and provides a good feeling of washing after washing.

The liquid cleaning composition of the present invention comprises the following (a) and (b).
) component.

(a) Alpha olefin sulfonate.

(b) Polysaccharide.

The present invention will be explained in more detail below.

The alpha olefin sulfonate of component (a) is not particularly limited, but includes C□2-C0 alpha olefins, C1□-C1° vinylidene olefins, 01 obtained by the wax crack puffer method or improved methods thereof.
□～C process, sodium salt, potassium salt, triethanolamine salt, etc. of anionic surfactant obtained by sulfonating inner olefin etc. using a sulfonating agent such as dioxide ion and then hydrolyzing are preferable. Can be used.

(a) It is appropriate for the alpha olefin sulfonate to be blended in the liquid cleaning composition in an amount of 2 to 40% by weight,
Preferably it is 3 to 30% by weight.

When the blending amount is less than 2% by weight, the effect of improving the creamy feel of the foam and the finish after washing tends to deteriorate, while when it exceeds 40% by weight, cloudiness may occur at low temperatures.

The polysaccharide of component (b) is Acinetobacter type (
Examples include lipopolysaccharide produced by Acineto bacter, which is a type of so-called biosurfactant. Such lipopolysaccharide can be obtained, for example, from Petroferm (USA) under the trade name Emulsan.

This is a species of Acinetobacta (A T CC deposited Nα
α-emulsans (neo-emulsans), which are extracellular microbial protein-associated lipopolysaccharides produced by 31012) and obtained mainly when ethanol is used as a carbon source;
There are β-emulsans (protoemulsans) obtained when crude oil or hexadecane is used as the main carbon source. Acinetobacta species (A T CC deposited Nα: 31012
), the lipopolysaccharide produced by
-112201.

(b) The polysaccharide is suitably present in the liquid cleaning composition in an amount of 0.1 to 5% by weight, preferably 0.1 to 3% by weight. If the blending amount is less than 0.1% by weight, it will be difficult to sufficiently obtain a creamy hold and improve the finish feeling after washing, and it will be difficult to impart good smoothness and smoothness to the hair after washing. becomes difficult. On the other hand, if it is blended in an amount exceeding 5% by weight, the liquid cleaning composition may become cloudy and separate, which is not preferable.

In addition to the above-mentioned essential components, other components may be appropriately added to the liquid detergent composition of the present invention depending on its use and purpose. Such optional ingredients include anionic surfactants other than α-olefin sulfonate, nonionic surfactants, amphoteric surfactants, thickeners, ultraviolet absorbers, preservatives, emulsifiers, and anti-dandruff agents. One or more types of inhibitors, antioxidants, tonic agents, pigments, fragrances, etc. can be blended. Furthermore, lower alcohols such as ethyl alcohol and isopropyl alcohol can be incorporated into the liquid cleaning composition of the present invention to improve the compatibility of the composition system.

Highlights According to the liquid cleaning composition of the present invention, by using an alpha olefin sulfonate and a polysaccharide in combination, these act additively, and a fine creamy foam can be obtained during cleaning. , you can get a good wash result.

When used as a shampoo composition, it can provide a smooth feel after washing the hair. Further, the same applies when the composition is applied to other liquid cleaning compositions such as kitchen detergents and liquid cleaning agents for body use, etc., and it is possible to obtain a smooth feel on the hands and skin after washing.

EXAMPLES Hereinafter, the effects of the present invention will be explained in more detail with reference to Examples. First, prior to explaining each example, the test method used in the example will be described.

(1) Creaminess of foam Hair is divided into two parts, 3 g of the standard product and a test sample are applied to each of the left and right hairs, the hair is washed, and the creaminess of the foam on the left and right hair is sensory evaluated by a paired comparison table. The evaluation is as follows, and is expressed as the total score of 20 subjects.

(Scores) +2 points Test sample is preferred +1 point Test sample is slightly preferred 0 points Equivalent - 1 point Standard product is preferred -2 points Standard product is slightly preferred Number of moles of EO added 15 = 3)
A 10% aqueous solution of was used.

(2) Smoothness and silky feel Same as method (1), one head of hair was divided into two parts, 3g each of the standard product and test sample were applied, and the smoothness and smoothness of the left and right hair after washing and drying was evaluated by the subject. Sensory evaluation was performed.

Ratings, standard products, etc. are the same as in (1).

Examples 1 to 7 Liquid detergent compositions having the formulations listed in Table 1 were prepared, and according to the evaluation method described above, the creamy feel of the foam during hair washing,
The smoothness and dryness of the hair after washing and drying were evaluated.

As is clear from the results in Table 1, the compositions of the invention in Examples 1 to 7 were found to have better creamy foam feel, smoother hair, and smoother feel than the standard composition. It will be done.

On the other hand, Comparative Example 1, which did not contain Emulsan, and Comparative Example 2, which did not contain alpha olefin sulfonate, had creamy foam.

Neither the smoothness nor the silky feel of the hair was satisfactory.

(The following is a blank space) Examples 8 and 9 Two types of liquid detergent compositions were prepared according to the formulations listed in Table 2, and in the same manner as in the previous example, the creamy feeling of the foam during hair washing, the creamy feeling of the foam after hair washing and drying. The smoothness and dry feel of the product were evaluated.

(The following is a blank space) As is clear from the results in Table 2, even when the liquid cleaning composition of the present invention is blended with other ingredients such as sodium sulfate and fragrance, it is not affected by these ingredients. Compared to the standard liquid cleansing composition, the creamy feel of the foam, the smoothness of the hair, and the silky feel of the hair were all better.
