Hey Formulators ! Hope everyone is doing well !
I am working on Watermelon Gel in India. It is a crystal clear Gel with a dispensing pump. It sells really cheap, therefore all ingredients have to be affordable. I make it with Lubrizol's Carbopol 980.
Since watermelon is synonymous with cooling effect in Indian heat. I was trying to develop a gel with cooling effect. I have tried menthol crystals and menthol oil (Crystals do not dissolve in water obviously & oil causes turbidity). Crystals dissolve in Alcohol, however they lose their cooling sensation in Alcohol. And I simply cannot use Alcohol because it causes dryness, has a stingy smell and is technically not allowed.
My formula is
DM Water - Q.S
Propylene Glycol - 2
Carbopol 980 - 0.5
Watermelon Fruit Extract - 3
Hydroxyethyl Urea - 2
Preservative - 0.5
Color/Fragrance - Q.S
The gel has to look crystal clear, That is one of the selling points.
Hope to get some replies ! Thanks in Advacne !
