I've been checking into shea butter properties and ran across this description of grading. Understanding Grades of Shea Butter Below, you will find information to help you better understand the various grades of shea butter. The quality Grades are A, B, C, D and F. When chemical and physical analysis is performed on your butter, the grade is determined by the presence or absence of important nutrients. Grade A is the highest and best grade for personal care uses. Grade A has the highest amount of important nutrients and the lowest amount of undesirable ingredients. On the other hand, Grade D has the lowest amount of the important nut rients and contains high levels of undesirable nutrients. Grade B and Grade C is noted for having little or no undesirable nutrients but lower levels of the important nutrients. Grade B and Grade C are still very useful in the personal care industry. Loss of important nutrients and collection of undesirable ingredients may result from careless and improper extract ion techniques, and/ or improper post extraction management of the butter. Finally, Grade deterioration of shea but ter destined for the personal care industry may occur during refining the ref ining process. During the refining process, up to 75% or more of the important nutrients helpful in personal care management can be lost , thereby reducing the quality of the but ter. Refined and ultra refined shea butter is always Grades C, or D. Grade C and Grade D are more suitable for chocolate industry. US chocolate industry, by law, cannot use shea butter in the manufacture of chocolate. In the USA the law demands that only cocoa butter is used in the manufacture of chocolate. No cocoa butter substitutes are permitted. So what i'm getting out of this is all refined Shea is either grade C or D. So we are using a product with less of the important nutrients and quality??? When we purchase in coops and such is the grade ever mentioned by the supplier? Is anyone on here more informed on Shea grading than I? Please chime in with your knowledge.
