JPS606659B2 - solid fragrance deodorant - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solid aromatic deodorant using a waxy composition having a specific gravity of 1 or more.

BACKGROUND ART In recent years, products of a type in which a solid aromatic deodorant containing a fragrance, a surfactant, a gelling agent, etc. are mixed and solidified and function in water have been commercially available.

These products are placed in the water tank of a flush toilet and serve as fragrance, deodorizer, and cleaning. Since it is important for underwater drop type solid air freshener deodorizers to leave the surfactant contained therein at a constant concentration and for a long period of time, it must be allowed to settle in a water storage tank. Some have been implemented.

That is, conventionally, this type of fragrance has been precipitated in water by the following method. '11 Use in a heavy container. ■Use an activator with a heavy specific gravity. '3- Adding fragrances and activators to the resin. However, in method M, the container is bulky, and the container remains even after the fragrance and active agent have been released. In method (2), the rate of elution into the active agent is too slow and there is a problem in long-term use. In the method {3}, the elution rate is too slow to perform its function satisfactorily. Furthermore, there was a drawback that resin remained. Another possible method is to use a brominated compound or metal salt with a heavy specific gravity, but this poses problems in terms of biodegradability and safety after drainage. In order to solve the above problems, the present inventors have conducted various studies and found that the following collective esterification products consisting of polyhydric alcohols, dibasic acids, and fatty acids are effective. , and arrived at the present invention.

That is, the present invention uses 1 polyhydric alcohol having a valence of 3 or more and 4 carbon atoms.
-20 linear saturated aliphatic dibasic acids and 12 to 2 carbon atoms
An esterification product of the direct mirror saturated fatty acid 3 of 2,
2) using 0.5 to 1 mol for 111 mol, and '1
A waxy composition obtained by esterifying 2/3 or less of the residual hydroxyl groups of the ester obtained by reacting ', (2') with the legs is used as a gelling agent or solidifying agent, This is a garden-type aromatic deodorant for use in the garden.The structure of the present invention will be explained below.

The polyhydric alcohol used in the present invention includes glycerin,
Bentaerytrit, sorbitol, and condensates thereof, and the polyhydric alcohol containing 1 to 3 ethylene oxides and/or propylene oxides per hydroxyl group.
Polyether polyols with molar addition, etc., and dibasic acids include succinic acid, adipic acid, sepacic acid,
A linear saturated aliphatic dibasic acid having 4 to 20 carbon atoms such as -, 18-, and octadecamethylene dicarboxylic acid can be used.

As fatty acids, direct mirror saturated fatty acids having 12 to 22 carbon atoms such as lauric acid, myristic acid, valmitic acid, stearic acid, arachidic acid, and behenic acid can be used.
The ingredients are 0 dibasic acid per mol of polyhydric alcohol.
．． A waxy composition having a specific gravity of 1 or more can be obtained by esterifying 2/3 or less of the remaining hydroxyl groups of the condensate of a polyhydric alcohol and a dibasic acid with a fatty acid at a ratio of 5 to 1 mole.

The above composition ratio is the one at the time of reaction implantation, and the products are various condensation mixtures centered on this composition ratio. The esterification reaction is carried out under normal pressure or reduced pressure without a catalyst or by a normal reaction using an esterification catalyst such as an acid, an alkali, or a metal salt.

The resulting waxy composition has good compatibility with perfumes and surfactants, and is a moldable wax that does not lose its shape in water.

Therefore, it has the advantage that the rate at which the fragrance or surfactant passes into water can be freely adjusted by changing the ratio of the fragrance or surfactant to the wax. Furthermore, since the present waxy composition is appropriately dispersed in water, no wax remains even after the fragrance and surfactant are eluted.
Furthermore, since this product is composed of polyhydric alcohol, linear saturated di-salt fatty acid, and linear saturated fatty acid, it is highly safe, has good biodegradability, and does not cause environmental pollution problems. Since the present wax-like composition itself has a specific gravity of 1 or more, and the specific gravity of the fragrance and surfactant is also usually 1 or more, a molded product made from it has a specific gravity of 1 or more and easily settles in water.

From the above points, if the present waxy composition is used as a gelling agent or solidifying agent, it is possible to produce an excellent quality drop-in-water group-type aromatic deodorizer that eliminates the drawbacks of conventional products.

The above effects are first brought about by the aforementioned limitations regarding the number of carbon atoms, molar ratio, and residual hydroxyl groups.

Next, examples will be shown.

Into the four flasks, 184 g of glycerin, 100 g of succinic anhydride, and 244.5 g of stearic acid were charged, tin chloride was used as a catalyst at 0.3% of the total amount charged, and xylol was added as a refluxing solvent at 5% of the total amount charged. % added, 160~
The reaction was carried out at 230qo for 5 hours.

After the reaction was completed, the solvent was distilled off and the catalyst was separated in a furnace to obtain the desired waxy composition. Similarly, experiment No. 1 in Table 1 was used. Waxy compositions 1 to 10 were prepared. 1-2 Physical Properties The composition ratio and general properties of the waxy composition are shown in Table 1.

Next, the compatibility of the surfactant and the moldability of the waxy composition were investigated.

The results are shown in Table-2. In the compatibility test, the waxy composition: surfactant (polyoxyethylene-oleyl ether) = 1:1 (weight ratio) was heated and dissolved, then mixed, and the state of the solution was examined.

Regarding moldability, the mixture of the waxy composition and surfactant used in the compatibility test was placed in a mold, cooled to room temperature, and the solid material thus obtained was placed in a beaker containing water. The sample was hung and stirred for 3 hours using a magnetic stirrer to check for deformation.
