This natural, ground "seed powder" will produce lovely shades of orange to yellow-orange in both CP and melt & pour soaps. It's also widely used as a food colorant, and since this product is food grade, it can safely be used in either beauty care or food recipes.
Annatto has also been found to hold properties that keep food from spoiling, as it inhibits the growth of Bacillus cereus, Clostridium perfringens, and Staphylococcus aureus.
To use in cold process recipes, add 2 tablespoons to 3/4th cup warm oil and steep for 1 hour. Strain and use the colored oil as part of your oil phase. The color achieved for a 10 pound batch of soap will be deep orange. To achieve a yellow-orange tone, cut the amounts mentioned above in half. You can also add the annatto directly to the lye/water phase. Stir well into HOT lye/water, and proceed with your recipe as normal.
For melt & pour soaps, simply steep in a small amount of glycerin, and add drop by drop to melted soap base until the desired color is achieved.
