I've been messing around with a formula for a CBD cooling massage oil. Originally it was a CBD Balm with a base of soybean oil and thickened with a couple waxes.
I changed the base to mineral oil and removed the waxes for a lighter skin feel to use it as a massage oil in a pump or spray. I can't share the full formula as it's company property but the ingredient list is minimal as this was for personal use so I didn't need to add any claim ingredients, only functional ones.
I can share the percentages of active ingredients though:
CBD Isolate 1%
The balm I made has the same amount of active ingredients but has a noticeable cooling effect once applied. I tried adding 1% Frescolat MGA to see if it would change anything and there was no obvious change. No cooling effect at all. The only change I made between the two formulas was removing soybean and waxes and replacing them with the same % of mineral oil.
Does anyone know the reason for this? Or has anyone else encountered something similar?
