Shampoo formula causes hair dryness?
Posted by Abram on November 8, 2021 at 8:05 pmHey everybody,
I am trying to formulate a shampoo for daily use as follow:20% Disodium laureth sulfosuccinate8% cocamidopropyl betaine2% cocamide DEA2% glycerine4% polyquaternium-7Many users told me that causes some dryness of hair. I do not know the reason. Could you help me?Abram replied 2 years, 12 months ago 6 Members · 12 Replies -

What is the activity of the disodium laureth sulfosuccinate? Seems a high %
-
Reduce betaine and DEA to half.
Although i don’t think you shampoo makes the hair dry

You should follow recommended inputs from supplier.
We do not know what brand name you are using, therefore what’s the activity or those raw materials.If the shampoo is for oily hair, use higher input, if it’s for daily use, you can use mid point.
It can be even the polyquot-7. Try to reduce it to 2% and see how it goes. -
What do your users mean when they say it caused dryness?
You might try substituting Polyquarternium 10 rather than Polyquat 7. Also, your level of Polyquat 7 is too high, 1% is max necessary.
Also, what is the total % active of surfactant. More than 15% is very high.

If your surfactant percentage is within the normal range. You may want to inquire what shampoo yours is compared to? Are they using a shampoo that contains silicone which may feel more moisturizing?

but I am surprized that increasing the moisturizing agent may cause dryness
thanks for your concern -

Hello sir,
I am so excited to see your reply
1. “my users” means people who tried to apply my shampoo on their hair and told me their feedbacks
2. I find to that shampoo loses its desired viscosity on reducing the percentage of surfactants. How can I deal with that?
3. I try using disodium laureth sulfosuccinate because it is a mild surfactant, before I used SLES instead.Thanks for your sincere reply

It is a good point sir
I will check thisThanks for reply

Sulfosuccinates do not thicken easily / they are not salt responsive. You may need to use some sort of gum or polymer to thicken your formula.
Polyquaternium works great at lower % input. Not always “the more the better” works in cosmetic. If you use too much of a polyquat, the hair will feel terrible. I guess that is the problem with your shampoo. Plus probably high active matter input.
Also, you shouldn’t use pure silicones in your formula. There is no benefit to it, it will only destabilize your formula and kill the foam. Use some ethoxylated lipids, superfatting agents or similar.
