Designing your products as a line: Shampoo - dimethicones
Shampoo - How does it work?
Shampoo - What's in it? Surfactants
Shampoo - What's in it? Other ingredients
Shampoo - Increasing mildness & viscosity
Shampoo - Conditioning agents
Silicones like dimethicone or amodimethicone can be used in your shampoo at a low level - up to 2% - to increase conditioning. You don't need to use a solubilizer or emulsifier as the surfactants will help keep it in the mix, which is a great thing!
As an aside, amodimethicone can cause more build up than dimethicone. I encourage you to take a look at this post, if that interests you.
When I'm making something for my husband and know he might not use conditioner afterwards, I always include dimethicone in his shampoo as I want the maximum conditioning and shine I can get out of that product. When I'm making something for myself and I know I'll be using silicones in my conditioner, I don't. It's not that I worry it'll build up - my experience is such that in the past nine years of making things, my hair has never felt weighed down because of products - it's just I don't want to use something if it's pointless.
Dimethicone doesn't increase the mildness in the product or offer thickening, so there's no reason to include it for those reasons. It's purely for the conditioning feeling it leaves behind, so if you're using a conditioner after washing, feel free to leave it out.
Join me tomorrow to take a look at using proteins in our shampoo!
