Method for removing contaminants from cannabinoid distillates

A method for removing contaminants from cannabinoid distillates to yield purified cannabinoid distillates consisting essentially of:

• obtaining cannabinoid distillates additionally consisting essentially of one or more contaminants;
• mixing said cannabinoid distillates additionally consisting essentially of said one or more contaminants with ethanol and distilled water to yield a cannabinoid-ethanol-water solution;
• allowing said one or more contaminants to settle out of said cannabinoid-ethanol-water solution;
• separating said cannabinoid-ethanol-water solution into a purified cannabinoid-ethanol-water solution and residual contaminants separately;
• distilling said ethanol and said distilled water from said purified cannabinoid-ethanol-water solution to yield purified cannabinoid distillates;
• wherein the mixing of said cannabinoid distillates with said ethanol and said distilled water to yield said cannabinoid-ethanol-water solution consists essentially of
• adding said ethanol to said cannabinoid distillates at a ratio between 2:1 and 4:1 of ethanol by volume in mL to cannabinoid distillates by mass in grams, to yield a cannabinoid-ethanol solution;
• heating said cannabinoid-ethanol solution to a temperature between 40° C. and 80° C. to yield a dissolved cannabinoid-ethanol solution;
• adding said distilled water to said dissolved cannabinoid-ethanol solution at a ratio between 1:4 and 1:10 of said distilled water by volume in mL to said cannabinoid distillates by mass in grams, to yield said cannabinoid-ethanol-water solution;
• and,
• heating said cannabinoid-ethanol-water solution to a temperature between 40° C. and 60° C.;
• and,
• wherein the allowing said one or more contaminants to settle out of said cannabinoid-ethanol-water solution consists essentially of
• cooling said cannabinoid-ethanol-water solution to a temperature between −30° C. and 10° C., yielding a cooled cannabinoid-ethanol-water solution;
• and,
• allowing said contaminants to settle out of said cooled cannabinoid-ethanol-water solution for a period of time between 2 hours and 7 days.
