Uniform Standards of Jojoba Oil Quality

The parameters in the following table are adopted by the International Jojoba Export Council in an effort to establish consistency of testing and reporting. The methods determined to be most universally accepted are listed. Where the designated method is not specific enough to address all variables, a supplementary method is provided. The supplementary method provides more explicit instructions not given in the primary method.
