Abstract: Disclosed is a selective ester production process of an alcoholic hydroxyl group, which proceeds under chemically mild conditions, while having adequate environmental suitability, operability and economical efficiency. Specifically disclosed is a process for producing an ester compound, which is characterized in that an alcohol and a carboxylic acid ester compound are reacted in the presence of a compound containing zinc element, thereby selectively acylating a hydroxyl group of the alcohol.

Abstract: An object of the present invention is to provide a novel technology for preventing crystal precipitation of p-menthane-3,8-diol, and stable products utilizing this technology. Provided is a p-menthane-3,8-diol isomer mixture, wherein the mass ratio of cis isomers:trans isomers in terms of the relative configuration at Positions 3 and 4 is 55:45 to 45:55. Also provided are stable products and the like containing the p-menthane-3,8-diol isomer mixture.

Abstract: Disclosed is a cooling sensation agent composition or sensory stimulation agent composition which contains at least one of diester compounds of dicarboxylic acid represented by the formula (1) wherein A represents CH2 or CH?CH, n represents an integer of 0 to 4 when A is CH2, or 1 when A is CH?CH, B is an alcohol residue having 10 to 18 carbon atoms and containing a para-menthane skeleton, which may have a substituent, and C is an alcohol residue having 6 to 18 carbon atoms, which may have a substituent as well as a flavor or fragrance composition, a beverage, a food product, a perfume or cosmetic product, a toiletry product, daily utensil products or groceries, a fiber, a fiber product, clothes, clothing or a medicine, wherein the cooling sensation agent composition or the sensory stimulation agent composition is compounded.

Abstract: Antimicrobial compositions that include at least one aliphatic aldehyde component and allyl isothiocyanate are provided. Methods of reducing bacterial activity using the instantly disclosed compositions are also provided.
