Designing your products as a line: Shampoo - conditioning agents

When we take a regular or clarifying shampoo and add a conditioning agent or cationic polymer like polyquat 7 or honeyquat to it, we change it into a conditioning shampoo. If you're using a conditioner after washing, should we bother?

Yes! It doesn't take much to make a great impact - say up to 3% - but it makes a world of difference!

Have you ever washed your hair and felt it before conditioning? It can feel like straw, hard and scratchy, maybe a bit tangled. Adding a cationic polymer or dimethicone can make this feeling go away. You don't need much to make a difference, but I think it is an important inclusion in a shampoo. As well, we know that conditioning agents increase the mildness of a shampoo, which means our scalp will feel more moisturized and less irritated. We can also add dimethicone in low quantities - at up to 3%  - to a shampoo to get some awesome conditioning action.

The downside of using a conditioning agent in a shampoo is that sometimes they can build up. Something like cationic guar gum can lead to build up on our hair, so you might want to use a clarifying shampoo - one without condtioning agents - once a week to remove it.

Hello Susan, sorry for being unable to find answer in such a wealth of information you provide...
but i swear, i've looked before posting)
I have SLSa and SCI- both sort of powdered and i guess both, are without stearic acid added. My question is how much of stearic acid do we add in this occasion will it be the same 2-7% or more?And one more stupid question, sorry- how to convert grams into percentage?
Thank you very much beforehand, yours forever)), Irina.
