Is maltodextrin in shampoo just a bad idea? Have preservatives
I’ve got maltodextrin as high as 5% in my liquid shampoo formula, with preservatives Benzyl Alcohol-DHA combo (0.8%) + sodium benzoate (0.4%).
will my liquid shampoo spoil faster? I plan on doing challenge test, later, but given it costs $$$, I need to optimize my formula first.
Thank you in advance, experts. Love this forum -

Why do yo add maltodextrin? What’s it supposed to do?It’s bug food but not a too bad one given that it’s a pure carbohydrate and hence about as easily eaten by microbes as a lot of other ingredients. It provides the same elements (C, O, and H) as for example gelling agents or oils and this isn’t sufficient to guarantee growth, like a car requiring more than gasoline to run. Only if you combine it with ingredients rich in nitrogen, phosphorous, and trace elements will it become a ticking microbe bomb. -
I have the same question as @Pharma. What benefit are you hoping to get by using maltodextrin in a shampoo?
Shampoo is meant to wash things out of the hair. Maltodextrin is water soluble or dispersible so is is simply going to be washed down the drain if you use it. It doesn’t seem like a good idea to me.
