Help with Customizing Kojic Body Cream
Hey guys
I am adding to a new skincare line, and I have purchased the base (1 gallon) which is a kojic body cream from a reputable vendor. However it comes just as a base; I have to add the carrier oil and fragrance. The vendor advised to use the below formula:
95% base
2% carrier oil
2% extract
1% essential oil or fragrance
Here are my questions:
What carrier oil would work best for a 1% kojic acid body cream? Would 2% of the gallon mean 2.7 oz. of carrier oil?
When selecting a fragrance to add, what tips should I consider?
Any other guidance in terms of the actually mixing of ingredients would be appreciated.????

I am not really sure about the “reputable vendor” term.
The carrier oil should be emulsified. Not added after. You usually don’t put oils into emulsion, unless it is heat sensitive (e.g. cyclomethicone). The oil will be kind of free and might just feel heavy (if plant oil is chosen).
1% essential oil or fragrance seems crazy! First of all, you need to check regulatory limits for essential oils. If you add essential oils you need to add antioxidant. Fragrance at 1% is also high input. Depending on the fragrance, you sometimes need 0.1 - 0.2%.
Chemists/formulators work in grams, not gallons. So I would weight the product and mix it accordingly.
Some emulsions need to be mixed under low shear after/during cooldown, some can be high sheared again. Without formula/IL of the body cream we cannot tell.
