Description

  The present invention relates to cleaning compositions.

  Acylamino acid-based surfactants have recently received particular attention since they enable a weakly acidic formulation close to the pH of hair and skin. In particular, acylglutamic acid-based surfactants and acylaspartic acid-based surfactants are preferred to have a sharp feeling of use. However, acylaspartic acid-based surfactants are superior in foaming power, foam creamy property, foam retention performance, etc. as compared with acylglutamic acid-based surfactants, but the cleaning composition for cosmetics etc. The foam performance is inferior to laureth sulfate, which is generally used in the above. For example, Patent Document 1 discloses an invention of a detergent composition using an acyl asparagine-based surfactant, and describes that the composition has excellent foam performance. Further, Patent Document 2 discloses, as a detergent composition having improved foaming properties and thickening properties, acyl amino acids, polyoxyethylene alkyl ether sulfate, nitrogen-containing nonionic surfactant, organic acid or an organic acid or the like. A detergent composition containing salts, alcohols and glycyrrhetinic acids is disclosed.

  The combined use with the powder component is effective in increasing the detergency by the physical friction effect and adsorbing dirt on the particle surface.

  Further, when used in combination with an oily component, it has an effect of solubilizing oily stains due to the solvent effect of the oily component, and thus is suitable for improving the detergency. Among oily components, the combined use with silicones is particularly effective for giving a refreshing feel after use.

  Furthermore, the combined use of a humectant can prevent roughening of the skin due to excessive degreasing, and contributes to improving the feeling of use.

  The combined use with a sequestering agent and an antioxidant is effective in preventing a change in the product under a long-term or severe use condition and continuously providing a good feeling of use.

<Form>
The form of the cleaning composition of the present embodiment is not particularly limited, and includes, for example, liquid, gel, paste, foam, solid, powder, tablets and the like, including hair and fingers. In consideration of convenience at the time of use as a body cleanser, liquid, gel, paste, and foam are preferable, and liquid, gel, and paste are more preferable, and liquid is more preferable. .

  Next, the present invention will be described in more detail by way of examples, but the technical scope of the present invention and its embodiments are not limited thereto. The properties of the cleaning compositions obtained in the examples were evaluated by the following methods.

<Preparation of detergent composition>
The components (a) and (b) described in Tables 1 and 2 were mixed at the ratio (% by mass) described in the tables to prepare a detergent composition.

<Evaluation of foam performance>
3.3 g of the detergent composition was made up to 300 g with purified water, put into a mixer and stirred for 30 seconds, and the height of the foam immediately after was taken as “foaming power”. In addition, the fineness of the foam immediately after was monitored to determine the "creamy property of the foam". Then, the height of the foam when left for 5 minutes was defined as "foam retention". The three evaluations of "foaming power", "creamy property of foam", and "foam retention performance" were comprehensively evaluated by 10 male and female panelists in 10 stages and shown as "evaluation of foam performance".
The temperature to be measured was 25 ° C.

<Protein denaturation>
An aqueous solution in which chicken egg albumin was dissolved in a phosphate buffer aqueous solution, a detergent composition (aqueous solution: detergent composition) were mixed at a ratio of 1: 9, and after standing overnight, turbidity (660 nm) was measured.

[Examples 1 to 9, Comparative Examples 1 to 7]
The physical properties of the obtained detergent composition were evaluated for foam performance and protein denaturation by the methods described above. The results are shown in the evaluation columns of Tables 1 and 2.

  The cleaning composition of this example showed excellent results in foam performance.

  Since the cleaning compositions of Examples 1 to 6 satisfy the predetermined requirements, they have good foaming performance. However, the cleaning compositions of Comparative Examples 1 to 4 do not satisfy the predetermined requirements. As a result, the foam performance was significantly inferior.

  The cleaning composition of this example showed excellent results in protein modification.

  Since the cleaning compositions of Examples 7 to 9 satisfy the predetermined requirements, there is little protein modification and no turbidity, but the cleaning compositions of Comparative Examples 5 to 7 satisfy the predetermined requirements. Since there is no denaturation, the protein denaturation is large and turbid, and the result is that the protein denaturation is significantly inferior.

  The cleaning composition of the present invention has practically improved foam performance such as foaming power, foam creaminess, foam retention, etc. by changing the acyl group of the acyl aspartic acid surfactant to a specific acyl group. It can be used as a detergent composition that is highly safe and has little protein denaturation and high safety.
