Coloring Perfume and Yield Calculation

Here are the answers to your questions about coloring perfume:

1. Can water-soluble pigment be used to color perfume?
   It depends on your perfume formula. If your formula includes water, you can use water-soluble pigments by mixing them with the water component of your formula. However, if your formula contains only fragrance oil (which is considered oil) or mixes fragrance oil with alcohol (which also mixes with oil), you should use oil-soluble pigments.
2. How many ml of perfume can 10g of fragrance oil make?
   The amount of perfume you can make depends on the concentration ratio you use. Based on typical ratios for body spray perfume mixed with Ethyl Alcohol:
   • Using a 30% fragrance oil : 70% Ethyl Alcohol ratio, 10 grams of fragrance oil can make approximately 33.33 grams of perfume.
   • Using a 50% fragrance oil : 50% Ethyl Alcohol ratio, 10 grams of fragrance oil can make approximately 20 grams of perfume.
     
     Please note that these amounts are in grams. To convert grams to milliliters (ml), you would need to know the density of the final mixture, which is not provided.
3. When adding color to perfume, do you need to dissolve the powder color in water first?
   Generally, no. Perfume oil does not mix with water; it mixes with oil or alcohol. If your perfume formula contains water, you would dissolve the water-soluble pigment in the water part. But if your formula is primarily fragrance oil and alcohol, you would use oil-soluble pigments and mix them directly or dissolve them in a small amount of the alcohol or oil component, not water.
