Hydroalcoholic solution
Hi, I received a request to reproduce an existing formula (mainly to respect the INI). This is a 38% alcohol hair lotion. In inci after water and alcohol we find propylene glycol and then peg40. in the formula there are some oils (but given the original touch I don’t think more than 1-2%) that I solubilized in the peg with a ratio of 1: 4. this phase in water is transparent, the alcohol phase (with some alcoholic extracts) in water is transparent but when I combine all three phases (tried with different orders) it becomes milky. I think I am doing something wrong in the production method. do you have any suggestions?
thank you very much

@P89 Does the milky look stays overnight? In some cases, you can have this look for few hours, and the your product becomes clear. Now, try to add alcohol slowly, letting the product get clear after every addition. If this doesn’t help, then it means you need to add more solubilizer (or even better, more alcohol).

i’ll try to add it slower because it’s milky for a week.
