Color Changes in Hand Wash

Hi,

I am making a hand wash with this is formula :
SLES 10%, Potasium Cocoyl glycinate 8%, Lauramine oxide 8%, Fragrances 1%, PEG-40 Hydrogenated Castor Oil 2%, Colorant (red) water soluble 0.01%, Propylen glycol qs, Na2EDTA qs, Phenoxyethanol 0.5%, Aqua ad 100%.

After 1 week in room temperature the red color changed to brown-orange. 
What makes the color changes ? Reaction between surfactant and the fragrance ? Or the colorants was oxidized ? Or any unsuitable surfactants i've used in the formula ?

Thank you for all the suggestions.

    Colours are regulated and (1) must be accepted by the cosmetics industry and (2) you must test for stability. I don't know where your location is so I can't comment further. Obviously in your case (2) has not succeeded.
