Description

[Detailed description of the invention] Himi 1j1 relates to soap compositions.

Various proposals have been made in the past to improve the O performance of solid soaps, but the present invention has been made specifically to find a soap composition that is less irritating to the skin and has an excellent O feel after use. Nine results have been reached.

That is, Himi Meisha provides a soap composition characterized in that it contains a phospholipid and a fatty iron as a solid soap base material.

The present invention will be explained in detail below.

First, in the present invention, the solid detergent base material, fatty acid salt, lauryl sulfate, N-acyl glutamate, etc., are commonly used as a so-called cleaning agent.

Fatty acid salts are those commonly used as so-called soap electrolytes, and are usually C6 to On 81 degree saturated or unsaturated fats@O alkaline metal salts, including alkaline earth salts, ammoium salts, and organic base salts. Examples include sodium salt, )ium salt, and organic base salts such as triethanolamine salt, brobanolamine salt, and guanidine salt. Examples of lauryl sulfate include sodium lauryl sulfate, K
-As the acylglutamate, sodium N-acylglutamate is preferred! used.

Examples of the phospholipid include phosphatidylcholine (lecithin), phosphatidylethanol, phosphatidylserine, phosphatidyl isositol, and phosphatidine. Of course, a mixture of these 21111 or more types can also be used, but it is most preferable that the content of phos-7-atedylcholine in the phospholipid is about 10-0%.

In practical terms, the phospholipid is soybean phospholipid.

O using egg yolk phospholipid is preferred.

The amount of phospholipid O contained in soap products is usually 0.
/~IQ weight, preferably θ, J~! Weight duck, more preferably σ, j-7 weight duck is used.

If it exceeds 10% by weight, it is not preferable because the detergency may decrease and product stability may be impaired.

When blending in the composition of the present invention, phospholipids are not added during the alkaline saponification reaction of fats and oils, which is the seventh step of soap production, because phospholipids may be hydrolyzed in alkali.1 Normally, phospholipids are not added during the finishing step. Toning, which is
It is applied to the soap base just before incense is added.

Furthermore, in order to completely avoid the risk of decomposition of the phospholipids due to excess O alkali, K is more preferably prepared beforehand in an alkali-stable and oil-soluble substance at a temperature between room temperature and 70 cm. The method used is to dissolve it in water and knead it into the soap base material.

In the present invention, a fatty acid ester is used as this substance.

That is, in the present invention, fatty acid esters used together with the phospholipids include fatty acid esters of higher fatty acids and monovalent higher alcohols. The above fatty acids include C, ~3. Preferably, the number of carbon atoms is about CWt~l, and if the carbon number is less than l, it is preferable mainly from the point of O irritation to the skin, and on the other hand, it is preferable from the point of view of the feel to the skin of carp, which is larger than carp.

That is, as a fatty acid, 1, for example, laurilein ff
Examples include unsaturated fatty acids such as i. Also.

- Examples of the above-mentioned alcohols include those from C Hatake to Gyokuden O, such as dodecyl alcohol and z listyl alcohol.

stearyl alcohol, octyldodecyl alcohol,
Examples include hequinadecyl alcohol and cetyl alcohol. Komeuchi, low freezing point.

From the viewpoint of high boiling point and stability in air, chain-like and branched ones are preferable, such as hexdecyl alcohol, octyl dobutylene alcohol, and cole.

That is, the fatty acid esters include octyldodecyl myristic acid, octyldidodecyl oleic acid, and octyldodecyl oleic acid.

Hexyldecyl dimethyloctanoate is preferably used.

The amount used is usually 0.7~ in 1 soap! It is selected from a range such that the weight% stiffness is achieved.

The composition of the present invention is further blended with other ingredients according to the purpose in a conventional manner to produce soap.

In addition, additives that can be added include, for example, superfatting agents such as higher alcohols and higher fatty acids to make the foam more foamy, and sulfur, e-acetyl acid, and vitamins to prevent rough skin. agents, bactericidal agents such as lucresol, PR buffers, water softeners, polyhydric alcohols, Oa feathering agents such as sucrose, various carp chelating agents, other fragrances, dyes, etc.

The composition of the present invention has the following characteristics.

■) Extremely low irritation to the skin, providing a non-sticky feel on the skin.

11M) Excellent foaming properties.

■) Excellent feel after use.

In other words, the present invention will be explained in more detail with reference to examples.
(The present invention does not exceed its gist.)

The invention is not limited to these examples.

In the examples, % and O indicate 1% by weight.
