Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention, by blending skim milk powder, softens the stimulus to the skin and has a good lather, for use in hard water such as soap for makeup, bath soap and beauty soap. It relates to soap such as (transparent soap).

[Conventional technology and its problems]

The surface of the skin is kept smooth due to the secretion of sebum, but after a long time, the sebum is decomposed by oxygen in the air and finally converted into a substance that damages the skin.

In addition, the sweat secreted from the sweat line leaves salt and urea on the surface of the skin after the evaporation of water, which stimulates the skin and causes various skin diseases such as asemo.

The sebum, salts and the like secreted from the skin adhere to the skin together with dust and cosmetics that are externally attached to form skin. Various washing agents are commonly used to wash away these impurities and keep the surface of the skin clean.However, in order to effectively achieve the washing purpose, degreasing power and washing power are too strong. There were problems such as rough skin and irritations on the skin (published by Nanzandou Co., Ltd. on April 20, 1964, co-authored by Toshiaki Yasuda and Bunichiro Hosoda, Science of Beauty-Hif and Cosmetics-83-86).

[Object of the Invention]

The present invention increases the foaming property by blending skim milk powder in cosmetic soap, bath soap and beauty soap, and produces a soft-feeling foam, and also has an excellent feeling of imparting moisture and smoothness to the skin. The purpose is to provide hard water soap.

[Structure of Invention]

 The present invention is a soap for hard water containing skim milk powder.

The present inventor found that it is possible to produce excellent cosmetics by adding skim milk or reduced milk as an emulsifier to the basic cosmetics department, and applied for a patent. By blending skim milk powder in a ratio within the range of 5.0 to 10.0% by weight, a soft foam is formed, foaming property is increased, and soap that can be used even in hard water with excellent feel is provided. The present invention has been found out and the present invention has been completed.

Instead of using skimmed milk powder, skim milk or reconstituted milk may be mixed with soap at a ratio within a range of 5.0 to 10.0% as a solid content, and then water may be evaporated.

The soaps to which the present invention is applied include makeup soaps, bath soaps, beauty soaps, etc. containing sodium salts of higher fatty acids as main components. The additive of skim milk powder is preferably 5.0 to 10.0% by weight. Below 5% by weight, there is no noticeable effect, and 10.0
This is because, when added in an amount of not less than 10% by weight, not only the coloring property is deteriorated but also the shapeability is deteriorated, and even if it is added more than that, no further effect can be obtained.

Next, the present invention will be described in detail by taking makeup soap and beauty soap as examples.

1. Makeup soap Cooling the soap base obtained in the boiling step and drying it into flakes or powder, add 5.0 to 10.0% by weight of skim milk powder when adding flavors, colorants, etc. The mixture is put into a roll and a well-mixed mixture, and then it is pressed and solidified by kneading and compression.The protein content in the skim milk powder is further refined by physical impact such as heating, rubbing, and kneading. It changed into a protein-based film substance, which was combined with soap molecules, and the finished product had a slight tint but became glossy, giving it a high-class appearance.

Its foaming ability was excellent even in hard water, giving it a soft feel and a feeling of use, and it was proved that there was no stimulus on the skin.

In terms of foaming power, since hot springs near the coastline contain seawater, ordinary makeup soap does not foam as much as soft water, and
It is common knowledge that a lot of soap residue is generated, but the cosmetic soap (A) of the present invention and a commercial cosmetic soap (B) were finely ground, and 1 g of Nessler tube and 40 g of seawater were added and the result of shaking for 5 minutes was ( A) melted into a milky white color, and soft, slightly large foaming occurred.

(B) did not swirl and did not settle and foam.

Therefore, the cosmetic soap of the present invention is useful as a soap for hard water.

2. Beauty soap (transparent soap) Just before the frame kneading step, as in the case of the above-mentioned makeup soap, 5.0% by weight of skim milk powder is added to the soap base, and the mixture is stirred and poured evenly to solidify. Compared with the conventional product, the finished product loses its transparency a little, but the skin feels good and the foaming is outstanding.

The product of the present invention was compared with a commercially available product and was found to have excellent foaming power, a mild action on the skin, and the feel of the skin after washing was not dry, and it was smooth and had a satisfactory feeling of use. ..

Claims (1)

[Claims] 1. A soap for hard water comprising skim milk powder in a proportion within the range of 5.0 to 10.0% by weight.
