Please critique a formulation (personal product): need to get rid of warming sensation
Hello!
Here is a formula that we are testing:Aqua (Water) 93.10
Ultrez 10 (carbomer) 0.30
Biolin (Inulin Alpha-glucan oligosaccharide) 5.00
Natcide (Parfum —>used as a preservative) 0.70
Witch hazel 0.30
Sodium Hydroxide (10% Solution)
The product purpose is to be used as a gel that aids for wiping for folks with hemorrhoids. Testers report slight warming sensation for several seconds after using it. My questions: I think it’s Sodium Hydroxide. What do you think? What can we use instead?
Best,
