LEARN ABOUT UNIFORM STANDARDS FOR JOJOBA OIL QUALITY HERE
Here you can learn more about uniform standards for 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.
