  • Discoloration of body cream due to fragrance?

    Posted by MOKKW2 on May 21, 2023 at 12:05 am

    Hi,

    I am selling these creams with different scent at craft shows and i find out one of them discolor after a few weeks of making them. The fragrance is apple sage from brambleberry and it does not have vanilin. The color of the fragrance is slight yellow, but not this yellow and it blends well when i make them and at least for the first few weeks. For bigger jar, you will see the yellow color is specifically on the top, not the bottom in a clear glass jar. I thought i used sodium phytate as a chelating agent might help but it doesn’t…

    The texture and the smell doesn’t change, in fact customer didn’t notice but it is bothering me.

    Please help me, what else i can use the stabalize the color? Is it of UV light due to clear jars?

    Here is my ingredients list:

    Aqua, kokum butter, calendula, chamomile, bamboo extract, safflower oil, apricot
    kernel oil, emulsified wax, glycerin, dl-panthenol, vitamin e,
    essential oil, jojoba oil, hydroxyethylcellulose, Phenoxyethano, Ethylhexylglycerin, sodium phytate, citric acid (PH adjustment), fragrance

    Just wondering if it is oxidation of the unsaturated fatty acids in the apricot kernal oil that is causing the colour change. I am unfamiliar with some of the other oils used.

    I have used that fragrance oil and it often discolors to that sickly yellow. Weirdly, in anhydrous things, exposure to light will often (temporarily) reverse the discoloration. I’d love to know which aromachem is the culprit.

      My apologies, I looked for photos & their fragrance I’ve had go yellow is blackberry sage. The apple sage browned slightly but didn’t yellow for me.

    It could be due to the essential oils as well. Which essential oils did you use?
