7 l of distilled water is added to 350 g of the genus Gelatin and the aqueous mixture is heated to produce a Gelatin solution. And 205 g of Borneol, 50 g of p-oxybenzoic methylester, 30 g of p-oxybenzoic propylester, and 0.5 l of l-menthol are solved with 3.5 l of ethanol to produce a Borneol-ethanol solution.
