Abstract:

A discussion of the types of oil now commonly used on the Pacific Coast. The present tendency of using oils with larger amount of sulfonatable material is possible through the use of lower viscosities. Such oils are cheaper than the heavier and more highly refined ones and also for some purposes may have a greater insecticidal value. Laboratory data is given on the values for oils of different viscosities, also changes in viscosity through field temperature variations. The preservative action is shown of pine tar oils when used in small percentages with emulsions made with casein or blood albumin.
