Diluting Fragrance Oil for Cream Formulations

It is common for fragrance oils to be highly concentrated, making even a small amount too strong for a formulation like cream. To achieve the desired scent intensity, you can dilute the fragrance oil before adding it to your cream base.

Here are some common diluents you can use, as discussed previously:

• Propylene Glycol or Dipropylene Glycol: These are effective solvents for fragrance oils and can also help the scent last longer (act as a fixative). Propylene Glycol (ID 138) and Dipropylene Glycol (ID 488) are good options.
• Butylene Glycol: This can also be used as a diluent and is considered gentler with a lower risk of skin irritation compared to Propylene Glycol. Butylene Glycol (ID 320) is a suitable alternative.
• Ethyl Alcohol: Alcohol helps the fragrance to diffuse and spread the scent more widely, but it may cause the scent to dissipate faster. You can use high-purity Ethyl Alcohol (ID 706) or Perfumer Grade Ethyl Alcohol (ID 35354).
• Flora Fix: This ingredient is also mentioned as a potential diluent that can help with scent longevity, although specific product details were not available in the search results.

Dilution Ratio:

There is no single fixed ratio for diluting fragrance oil. The appropriate ratio depends entirely on the desired strength of the scent in your final product. It is best to start with a very low dilution (e.g., 1 part fragrance oil to 9 or 19 parts diluent) and test the scent strength. You can then gradually increase the concentration of the fragrance oil in the diluent until you achieve the desired level of scent. Once you have a diluted fragrance mixture at your preferred strength, you can add this mixture to your cream formulation.

By diluting the Lily Of The Valley Fragrance Oil (ID 2956) with one of these solvents, you will have much better control over the final scent intensity in your cream.
