BACKGROUND OF THE INVENTION
The present invention relates to a glycerin fatty acid ester and a polyglycerin fatty acid ester which have an effect of improving moldability with respect to vegetable candles. More specifically, by adding the moldability improving agent of the present invention, vegetable oil is used as a raw material. However, the present invention relates to a fat and oil for vegetable candles that is easy to use in a uniform state and has improved moldability during production, and a candle produced using this fat.
[0002]
[Prior art]
Conventionally, natural waxes such as those made mainly of stearic acid, wood wax, beeswax, carnauba wax, and montan wax have been used as candles, but these natural waxes are expensive and homogeneous. Is difficult to obtain, and there is a disadvantage that it cannot be obtained stably. Later, petroleum-based paraffin waxes that are cheaper and have better moldability have been used.
[0003]
However, candles using petroleum-based paraffin wax have the drawbacks of poor mold releasability during molding, and black smoke, exhaust gas, and strange odors during combustion. Therefore, a method of adding mineral oil (see Patent Document 1), a method of adding an alkylene glycol having an alkyl group with 2 to 5 carbon atoms (see Patent Document 2), and the like are disclosed. However, even though these methods are used, the releasability is improved, but the problems of peculiar black smoke and odor remain.
[0004]

Japanese Patent Laid-Open No. 11-269389
In addition, since paraffin wax is obtained from petroleum, there are many problems such as oil depletion problems and environmental destruction problems in terms of the environment.
[0006]
Thus, recently, attention has been paid to a method of using hardened oil obtained from vegetable oil instead of natural wax or paraffin wax as fat and oil for candle. This hardened plant oil is often obtained as a by-product after separating liquid oil from vegetable oil, is inexpensive, and can be supplied in large quantities. In addition, candles made from vegetable oil eliminate the disadvantages of burning black smoke, exhaust gas, and offensive odor, which are characteristic of candles made from paraffin wax, and many problems such as oil exhaustion problems and environmental destruction problems of current candles. Can be addressed.
[0007]
However, when molding into a candle with only the above-mentioned plant-cured oil, the solidified state of the fats and oils is poor, the surface becomes rough due to the generation of coarse crystals, and further cracks occur. It has a problem that it is difficult to mold it. As a method for producing a candle using plant hydrogenated oil, a method of mixing margarine with coagulated oil (see Patent Document 3) is disclosed. However, this method can reduce the black smoke and odor peculiar to candles made of natural wax, paraffin wax, etc., but problems with the formability of plant candles remain, such as the surface of the candle becoming rough. There is.
