    Dear All, am John and I need help. which ingredient can I use to stabilize the colour of my formulation? The product in question is a weave spray that contain Nutrilan i, dehyquart A-CA, polysorbate 60 and ethanol. How do I keep the colour stable? It changes when exposed to the weather.

    “Nutrilan® I-Powder is a collagen protein hydrolyzate that displays good skin compatibility and improves the dermatological characteristics of anionic surfactants.” (UL Prospector)

     - and you are using it with a cationic surfactant. Unless there are other ingredients you haven’t mentioned … this seems like the start point.

    that’d be your Nutrilan I; unless they’re extremely pure, collagen/keratin derivatives are terrible for causing discoloration

    Does you product change color only when it’s exposed to the weather?  For example, If you keep you product in a clear / transparent glass container, does it change color, also?

    Did you check pH of the product on constant Time Interval? For example, weekly for the period of 3 months starting with the Manufacturing Date?
    Does your product have Vitamins and/or Anti-Oxidants?

    The product is packaged in a transparent PET bottle. The product contains Cetrimonium chloride, polysorbate 60 and Nutrilan i 50

    Use benzophenone-4, it would definitely solve your prob.
