The present invention relates to a lubricated refrigerant for use in refrigerators employing hydrofluorocarbon coolants such as R 134a, R 32, R 125 and the like. The lubricated refrigerant contains fluorocarbon coolant, synthetic oil and a carbodiimide compound represented by the following general formula. R.sub.1 --N.dbd.C.dbd.N--R.sub.2, wherein R.sub.1 and R.sub.2 represent hydrogen atoms or hydrocarbly groups or nitrogen and/or oxygen containing hydrocarbly groups, and R.sub.1 and R.sub.2 may be the same or different groups. The refrigerant composition according to the present invention preferably contains said hydrofluorocarbon coolant and said lubricant at a given blending ratio.

Refrigerant composition containing carbodiimide

A hard butter of the present invention is obtained by adding 0.05 to 20% by weight of polyglycerol fatty acid ester(s), which is prepared by binding four or more moles in average of fatty acid(s) to polyglycerol(s) having five or more in average of hydroxyl groups, to a hard butter. With the use of the hard butter of the present invention, the anti-blooming properties of a chocolate are enhanced with little limitation on the composition of the same. In particular, chocolates containing trans and lauric hard butters can be more freely compounded thereby than in the case of conventional ones.

A cocoa butter substitute comprises sal fat obtained by extracting the fat from the seeds of Shorea robusta and then refining the resulting product. The cocoa butter substitute has a hydroxy value of not more than 16, a solid fat index of not less than 48 at 30.degree. C., a cooling time, at which the maximum point appears in the cooling curve, of not longer than 120 mins. and the maximum point temperature of not less than 17.degree. C.
