To many Humectants in a formula?
Hi everyone! ???? would love your opinion I’m in the midst of developing a formula a serum type product with hydration claims. So I was wondering does including a high percentage of different Humectants have a negative impact on the skin? The formula would contain around 30% total of different Humectants( Sodium Lactate, sodium PCA, Propanediol, Glycerine, Betaine, sacharide Isomearate ,Aquaxyl different weights of HA) now I know that it’s effectively doubling up on some ingredients that have a similar mode of action. But some of it is for Marketing as well. So would love to know if there is any adverse effects that can happen at such a high load of Humectants?
Many thanks in advance. ???????? -

In my opinion, yes you have too many humectants. It is unnecessary, wasteful, increases formula cost, production time and chemical inventory. All this for zero additional benefit to the consumer.
If you want the marketing story, buy a blend of humectants and put it in the formula at 1% (or less). Then get all your humectant benefit from something like Glycerin.
Why use a half a dozen ingredients when one will do?
Don’t consumers want more simple ingredient listings?
