Description

Description: TECHNICAL FIELD The present invention relates to a non-aqueous detergent composition and a method for producing the same.

[Conventional technology]

Conventionally, sulfur has been used as a therapeutic agent for skin diseases (mainly for external use for acne, seborrhea, chronic eczema, etc.) due to its keratin softening action and bacterial action. Polysulfides obtained by reacting powdered sulfur with alkali or alkali sulfide are also known.

Since these are soluble in water or alcohol, there have been known examples in which they have been incorporated into a therapeutic agent for dermatosis as seen in JP-A-50-129730 and JP-A-53-56326. Have been.

However, those containing a polysulfide in a detergent composition are not well known other than bar soap.

[Problems to be solved by the invention]

The present inventor added the polysulfide to the liquid or gel detergent, and when the polysulfide was simply contained,
It has been found that generation of hydrogen sulfide over time and the occurrence of polysulfide crystals are inevitable.

Therefore, the present inventor further conducted intensive studies to develop a detergent containing a polysulfide excellent in stability. As a result, the polysulfide was incorporated into a water-swellable clay mineral swollen with glycerin. As a result, it has been found that a significantly stable cleaning agent can be obtained, and the present invention has been completed.

[Means for solving the problem]

That is, the non-aqueous detergent composition of the present invention comprises a polysulfide
It is characterized by comprising at least M ₂ S _x (M: alkali metal, ammonia, alkaline earth metal, x: 2 to 6), a water-swellable clay mineral, and glycerin.

Further, the method for producing a non-aqueous cleaning composition of the present invention is a method for preparing a water swell obtained by swelling a polysulfide M ₂ S _x (M: alkali metal, ammonia, alkaline earth metal, x: 2 to 6) with glycerin. It is characterized in that it is blended in a clay mineral.

[Embodiments] Hereinafter, embodiments of the present invention will be described. Polysulfides used in (polysulfide) A M ₂ S _x (M: alkali metal, ammonium, alkaline earth metals, x: 2 to 6) is.

In the present invention, the polysulfide may be one isolated and obtained in advance.

However, it is preferable to use a polysulfide adjusted as follows. That is, an alkali metal, ammonia, and an alkaline earth metal are dissolved in glycols (ethylene glycol, propylene glycol, 1.3 butylene glycol, etc.), and sulfur is added thereto at 70 ° C. with stirring to cause a reaction. The produced polysulfide is represented by the above general formula. Specifically, sodium disulfide, sodium trisulfide,
Sodium tetrasulfide, sodium pentasulfide, potassium disulfide, potassium trisulfide, potassium tetrasulfide, potassium pentasulfide, ammonium disulfide, ammonium trisulfide, ammonium tetrasulfide, ammonium pentasulfide, cesium disulfide,
Cesium trisulfide, cesium tetrasulfide, cesium pentasulfide, cesium hexasulfide, etc., and one or two of these
More than one species is selected and used.

The compounding amount of the polysulfide is 0.014 to 1.0 in the total amount of the detergent composition.
5% by weight is preferable, and 0.035 to 0.49% by weight is more preferable. When the content is 0.014% or more, the effect on acne and the like is further improved, and when the content is less than 1.05% by weight, occurrence of rough skin can be suppressed.

(Water-swellable clay mineral) The water-swellable clay mineral used in the present invention is a layered silicate mineral belonging to smectite metal, and generally includes montmorillonite, beidellite, nontronite, saponite, hectorite, and the like. These may be either natural or synthetic products. Commercially available products include Kunipia, Smecton, (all of which are Kunimine Industries), Vegum (Vanderbilt), Laponite (Laporte), and fluorinated tetrasilicic mica (Topy Industries). These water-swellable clay minerals are used as raw materials, or those crushed to 2 to 100 μm by a ball mill or an atomizer or the like, and heated (preferably heated at 60 to 80 ° C.
More preferably, it is added to glycerin heated at 70 ° C.) and swelled with stirring.

The amount of the water-swellable clay mineral is 2 to 18 in the total amount of the composition.
% By weight, more preferably 5 to 12% by weight. When the content is 2% by weight or more, the viscosity becomes more appropriate and the stability becomes better. On the other hand, when the content is 18% by weight or less, it is possible to prevent the viscosity from increasing during stirring and to perform stable stirring.

It is known that when an anionic activator is added to a system obtained by swelling a water-swellable clay mineral with water, the viscosity of the system is reduced. However, in the system swelled with glycerin, the viscosity was not significantly reduced.

(Multiple Selective Ingredients) Since the detergent composition used in the present invention is non-aqueous and does not contain water, it is preferable that the surfactant also contains a powdery or liquid anhydrous surfactant. . By incorporating a surfactant, it can be used as a detergent having excellent foaming properties.

These surfactants can be used as long as they are soluble in glycerin, but they can be used in the form of powder or granules on the order of μm even if they are insoluble. Specific examples include saturated fatty acid salts, unsaturated fatty acid salts, N-acyl amino acid salts, N-acylmethyl taurine salts, polyoxyethylene alkyl ether acetates, alkyl sulfates, isethionates, and the like. Salts include potassium, sodium, triethanolamine, basic amino acids and the like. The compounding amount of these anionic surfactants is preferably 5 to 40% by weight, and 15 to 30% by weight.
Weight is more preferred. If it is less than 5%, the foaming property is poor, and
%, Gelation may occur during dissolution, and stirring may not be possible.

The cleaning composition of the present invention may contain, if desired, components generally incorporated in cleaning agents, for example, moisturizing components such as higher alcohols, lanolin derivatives, protein derivatives, polyethylene glycol, 1.3 butylene glycol, polyoxyethylene propylene glycol, sugar and sorbitol , Polyethylene oxide, polypropylene oxide block polymer, alkylolamide type, etc., nonionic surfactants, sequestering agents, preservatives, bactericides, pH adjusters, ultraviolet absorbers, antioxidants, inorganic salts, pigments, and fragrances Etc. can be included.
