Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solid cleaning material composition. In more detail, after using a solid detergent, 1) a refreshing feeling;
The present invention relates to a solid cleaning material composition that has significantly improved usability such as smoothness.

°As a solid cleaning agent, use Yuru Soap7. There are also ``Sin 7'' and ``Doper 7゜'' which use synthetic surfactants as foaming cleaning agents.

Soap has traditionally been made by blending fragrances, coloring agents, etc. into a soap base obtained by reacting (saponifying) mixed fats such as beef tallow and coconut oil, or mixed fatty acids obtained by decomposing beef tallow and coconut oil, with an aqueous solution of caustic soda. can get.

-, h, N7T71 bar is a foaming cleaning agent containing α-sulfo fatty acid ester, isethionic acid ester, alkylaryl sulfone sulfonic acid, paraffin sulfonic acid, N-acylglutamic acid, and salts of the above-mentioned esters and acids. It is obtained by blending oils such as cetanol and fatty acids, fragrances, and coloring agents.

Conventionally, solid detergents have been used to remove tIj that adheres to the body or clothes.
It has been used to remove fk from j. However, recently, when used on the face or body, in addition to the cleansing power to thoroughly remove sweat and dirt, there is also a demand for ease of use with a smooth feeling and smoothness after use. It has become.

In particular, when cleaning the skin in V-fields where sebum secretion increases and sweating occurs easily, or when cleaning oily skin where dirt and sebum clog pores and are prone to acne, it is important to keep the skin clean after use. Light and smooth usability has become one of the important properties for cleaning agents.

For this reason, in recent years, talc, kaolin, titanium dioxide, and
(Blending inorganic powders such as hydrophilic acid, organic powders such as silk powder, starch, cellulose powder, rice bran, etc.)
There were problems such as noticeable cracks occurring during use, foaming properties being inhibited, and the skin becoming rough after use, probably because the degreasing property was too strong.

On the other hand, in the latter case, heat or alkali causes discoloration and odor, the soap becomes slimy when used, and the skin becomes sticky after use. As a result, when synthetic resin powders such as polyethylene and polyester are blended into soap bases, synthetic soaps, and barges, the above-mentioned drawbacks are not observed, and the usability such as lightness and smoothness after use is remarkable. The present inventors have discovered that this can be improved and have come up with the present invention.

The present invention will be explained in detail below.The synthetic resin powder used as an essential compounding component in the present invention is as follows:
Polyethylene, polyamide, polyvinyl chloride/polyvinyl acetate, polynysten copolymer, polyvinyl alcohol, polyacryloni*polypropylene, polyvinylidene chloride/polyurethane, polyethylene I no chloroxybenzene, polyvinyl alcohol, polyvinyl chloride copolymer There are three types: polyfluoroethylene, polystyrene, and polystyrene, which can be blended alone or as a mixture, but the appropriate amount to include is 02 to 20% by weight of the solid detergent composition (hereinafter referred to as (simply abbreviated as %) preferably in the range α4 to X5%.

If the blending amount is less than 2%, the effect of improving the usability of the detergent will not be sufficiently exhibited, and if the blending amount exceeds 20%, the shaping properties of the detergent may deteriorate or the foaming properties may be inhibited. If it exceeds μ, it will become rough during use, making it undesirable as a solid cleansing agent for face or body use.

The solid detergent composition of the present invention is basically a mixture of the above-mentioned synthetic resin powder in a soap base or a thin soap base, and the soap base or non-put bar base is manufactured by a known method. Follow.

Namely, animal fats and oils such as beef tallow and mutton tallow, coconut fth, palm oil, palm kernel oil, soybean oil, olive oil,
Soap bases are produced by saponifying vegetable oils and fats, such as cottonseed oil, alone or in mixtures with alkalis, or by neutralizing various fatty acids and resin acids.

On the other hand, Synte 7 Tovarbase contains α-sulfo fatty acid ester, isethionic acid ester, alkylaryl sulfonic acid, alcohol sulfate ester, olefin t-sulfonic acid, paraffin sulfonic acid, N-anulglutamine, and the above esters and salts. It is obtained by mixing an appropriate amount of cetanol, an oil such as a fatty acid, and an appropriate amount of water and thoroughly kneading the mixture.

In addition to the clay figurine synthetic resin powder, various compounding agents can be added to the solid detergent composition of the present invention as required.

For example, as a humectant that improves usability, Probile/Glycol, Glycerin/Polyethylene Glycol,
Sorbitol, maltitol, glycerin with propylene oquinide (hereinafter referred to as PO), diglycerin with po adduct, etc., alone or in combination, can be blended in the range of 0 to 70%.

Further, for the purpose of leaving a residual oil effect on the skin, perfatty acids as described below can be blended, and various skin protection agents can be blended. In other words, hydrocarbons such as squalane, olefin oligomers, petrolatum, and liquid paraffin,
Fatty acids such as stearic acid, isostearic acid, oleic acid, palmitic acid, myristic acid, and lauric acid, fatty acid esters such as sugar ester, lanolin, and isopropyl myristate, aliphatic alcohols such as cetyl alcohol, stearyl alcohol, and oleyl alcohol, and fats. Examples include group alcohols, fatty acid ethoxylates, silicone oils, vitamins, and anti-inflammatory agents.

Similarly, in the present invention, colorant stabilizers, fragrances, bactericides, etc. can be added depending on the purpose of use.

In addition, in the case of soap, the following surfactants can be added for the purpose of improving foaming properties and detergency, and preventing the formation of scum when used in hard water. That is, by blending α-sulfo fatty acid ester, acid, paraffin sulfonic acid, N-acylglutamic acid, salts of the above-mentioned esters and acids, and further alkyl betaine, alkyl sulfobetaine, etc.
(The following is a blank space) Next, the present invention will be explained in detail with reference to examples, and the effects of the present invention will also be described.

The effects were measured using the following test methods and evaluation methods.
