Leave-in conditioner vs Rinse Out conditioner
Hi. I am new to formulating and looking to copy a hair conditioner that has the ingredients below but I have some questions: 1) Can these ingredients be considered safe to use as a leave-in conditioner? Labels say “rinse out” but I’m not sure why. 2) The product is too thin, what could I add to thicken it? 3) Since water is the first ingredient can this be considered a “water-based” conditioner?
Ingredients: Water, Cetearyl Alcohol, Isopropyl Palmitate, Brassicamidopropyl Dimethylamine, L-Aspartic acid, Tetrasodium EDTA, Methylisothiazolinone, Methylchloroisothiazolinone. -

The preservative (Methylisothiazolinone, Methylchloroisothiazolinone) is not suitable for leave on applications.

1. Yes they can but it depends on the ingredient level. @ozgirl - is right in the EU you can’t use methylisothiazolinone in leave-on but there is a level allowed in the US.
2. You can thicken with HEC or Xanthan Gum or maybe increasing the level of cetearyl alcohol. It really depends on the rheology you are looking to achieve.
3. Yes, that would be water based.
