Classification

Classification

The United States Agency for International Development, Gassel Consulting, and many other companies have suggested a classification system for shea butter separating it into five grades:

A (raw or unrefined, extracted using water),

B (refined),

C (highly refined and extracted with solvents such as hexane),

D (lowest uncontaminated grade),

E (with contaminants).

Commercial grades are A, B, C.

The color of raw (Grade A) butter ranges from cream (like whipped butter) to grayish yellow,
and (Grade B and lower) it has a nutty aroma which is removed in the other grades.

Grade C is pure white[citation needed] While the level of vitamin content can be affected by refining, up to 95% of vitamin content can be removed from refined grades (i.e. grade C) of shea butter while reducing contamination levels to non-detectable levels.
