“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

Try adding chelating agent like edta, works for my formulation….

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