Adding Fragrance to Face Powder: Preventing Clumping
Question
I want to add liquid fragrance to my face powder formulation. However, I'm concerned about the powder clumping, especially since it may contain talc.
- What causes face powder (particularly if it contains talc or ingredients like Dipropylene Glycol often found in fragrances) to clump when liquid fragrance is added?
- What is the recommended method to add liquid fragrance to face powder to prevent clumping? Could this involve using a carrier powder like cornstarch, and what are the steps and proportions involved?
Answer
Based on the discussion:
Adding liquid fragrance directly to face powder can cause clumping because the powder (especially talc) can absorb the liquid and stick together. Also, many commercial fragrances contain ingredients like Dipropylene Glycol (DPG), which is a humectant and can cause talc to clump.
The recommended method to avoid clumping is to first mix the fragrance with a carrier powder before adding it to your main face powder:
- Choose a carrier powder: Cornstarch is suggested as a good option because it is less prone to clumping when mixed with fragrances containing DPG compared to talcum powder.
- Add fragrance to the carrier powder: Carefully add or spray the fragrance onto the carrier powder (cornstarch).
- Mix and let sit: Close the container and shake it to distribute the fragrance. Let the mixture sit for 1-2 days to allow the scent to fully disperse within the carrier powder.
- Combine with face powder: After the fragrance has dispersed in the carrier powder, mix this fragranced carrier powder into your main face powder.
Regarding proportions, the discussion suggests adjusting the amount based on your desired level of fragrance. The conversation did not cover how long the scent will last in the powder.
