General-Purpose Pure Fragrance Oil Compounds. Strongest possible concentration. This is the strength of oil companies such as F-JAS, Jackalovski and Cheeky Fragrance use to create their products as it is highly economical when used correctly with applicable supporting ingredients. Dilution may be required to achieve desired strength or compatibility in final product. As these fragrance compounds are pure, separation and/or fragrance bleed may occur in certain applications. To prepare the pure fragrance compounds for use in water-based formula, suitable emulsifiers or solubilisers must be blended with the oil. Fragrance Enhancers such as Dipropylene Glycol may be required if good diffusion (scent-throw) is required. Fragrance Oil Compounds at this concentration are hazardous and care should be taken to ensure safe usage in the production environment. A COSHH assesment should be performed before using fragrance oil at this strength and concentration.
