The object is to coat the paper. the object is to coat the paper at the recommended rate per unit area; the actual depth of impregnation is not so important because the fruit is preserved by vaporization of the diphenyl from the coating during storage. The temperature of the diphenyl-wax mixture should not be allowed to exceed 70'C (160'F) as a higher temperature will cause considerable loss of diphenyl by vaporization. 4. For Application in Warm Solvent: a) Diphenyl/25 Liquid Paraffin/75 The liquid paraffin should be a non-toxic, odorless, and tasteless medicinal (e.g. "Liquid Paraffin B.P.").
