Can mold grow in 30% coco glucoside?
I’m thinking of a shampoo with 30% coco glucoside.
Do you still need a separate preservative for mold?
I’m including broad-spectrum anti-bacterial preservative so no worries about bacteria.
It must be one big freak of a mold to be able to grow in 30% surfactant is what I am thinking.

What is pH?
What is your preservative?

I’m thinking of pH 4.7-5.5 and anti-bacterial and anti-yeast preservatives are caprylyl glycol and 1,2 hexanediol. I suppose I can add sodium benzoate.

Be careful, those are not true preservatives but rather preservative boosters. You will still need to add a true preservative, like sodium benzoate.

Thanks. But I wonder. When I did test it on microbial testing, they actually killed Gram positive and negative bacteria (cap+1,2 hex) in broth full of bacterial food. And a product I used for over a year in the bathroom, preserved with only low percentage of the above, did not have any bacterial growth (0 CFU) when I tested. But I’m aware that they are mentioned as preservative boosters commonly; I wonder why.

That is a question for the expert, @PhilGeis 🙂
