Results of appearance between samples of stability tests at different temperatures

From previous discussion about stability test, I post a question about differences between samples tests at 40C and 50C. Also if excess of heating can distort the results.

    what kind of products are you testing, and what are the results you've got so far?
    UK based formulation chemist. Strongest subjects: hair styling, hair bleaches, hair dyes (oxidative and non-oxidative) I know some stuff about: EU regulations, emulsions (O/W and W/O), toothpaste, mouthwash, shampoos, other toiletries

    thanks Bill, I want to evaluate stability of a shampoo and also an Alum deodorant cream. I'm only running room temp tests and samples are at the second week without changes in appearance. Regads
