How can I achieve a long lasting effect claim. I guess it would depend on the application but for example to create a long lasting moisturizing ? I bought one in the market but i cannot seem to find which ingredient is creating this effect.
Could be create it with a polyquaternium that has film forming capacity? may i use a carbomer with very slow time of release of the emollient. ? Does that work on skin or only in pharmaceuticals.. ?
I guess my confusion is because i cannot seem to find a good definition of the mechanism of long lasting.
