Oil and Soap

A device for imparting shear to a dispersion for the purpose of reducing the particle size of the dispersed material. Somewhat similar to a roll crusher. Examples of dispersions processed over a roll mill are pigment grinds (pigments dispersed in a fluid such as castor oil) and soap formulations (where the dispersed material includes fragrance oil droplets and pigments). 

The Technical Services function of AOCS establishes, revises, and annually updates AOCS Methods, the Official Methods and Recommenced Practices of the American Oil Chemists Society22 for fats, oils, and soap technology Spanish AOCS Methods, a Spanish translation of the more commonly used AOCS Methods and Physical and Chemical Characteristics of Oils, Fats and Waxes. Leaders of the methods development committees coordinate closely with AOAC International (formerly the Association of Official Analytical Chemists). AOCS Methods are recognized as Official Methods in US FDA activities and when litigation becomes necessary in industry trade. Additionally, the Technical Services function operates a Laboratory Proficiency Program (formerly the Smalley Check Sample Program) and oversees distribution and statistical analysis of 30 different series of basic laboratory quality assur-ance/quality control test samples. Certification as AOCS Approved Chemists, or as AOCS...

How to Use Soak 3 ounces of finely minced garlic cloves in 2 teaspoons of mineral oil for at least 24 hours. Add 1 pint of water that has V4 ounce of liquid dish soap mixed into it.

American Oil Chemists Society. Although there is no publication devoted exclusively to the field of edible fats, there is one very excellent American periodical devoted to the broader field of all fats and oils and related materials. This is the Journal of the American Oil Chemists Society, which is now in its thirty-fifth year of publication, initially as the Chemists Section of the Cotton Oil Press. In 1924 it was a quarterly called the Journal of Oil and Fat Industries, and it became a monthly in 1926. In 1932 the name was changed to Oil and Soap in 1947 the present title was adopted. This magazine not only publishes technical papers presented at the society meetings or written specifically for publication, but also it includes each month... 

Methods of analysis (ASTM D-128, IP 37) are available for the measurement of excessive acidity derived from oxidation. These methods cover conventional grease that consists essentially of petroleum oil and soap. Thus these test methods are applicable to many types but not all grease. The constituents covered by the test series are soap, unsaponifiable matter (base oil), water, free alkalinity, free fatty acid, fat, glycerin, and insoluble. A supplementary test method is also provided and is intended for application to grease that contains thickeners that are essentially insoluble in n-hexane and to grease that cannot be analyzed by conventional methods because of the presence of such constituents as nonpetroleum fluids or nonsoap-type thickeners, or both. These methods may not be applicable to grease analysis when lead, zinc, or aluminum soaps are present or in the presence of some additives such as sodium nitrite.
