Heat with cream, slowing down the darkening of the cream.

Postby wisediq » Fri Jul 19, 2019 11:30 pm

I leave the cream in a room with an average temperature of about 30-35 degrees during the day. The packaging is a transparent bottle. But not in the sun. It will only hit the light from the lamp. After 2 weeks or more, the cream will begin to change its color to a darker color in all formulas mixed. Including some formulas that have separate layers as well. Is there any kind of ingredient that can slow down the darkening of the cream?

Hello. - The formula is cream, meaning that it has both water and oil composition, is that correct or is it only the oil component? - I don't know if there is a sample of the cream that is not exposed to light. Store it with or not to compare the color, if not exposed to light, has a change of color or not to ensure that change caused by light It's not about whether the ingredient changes color on its own.

Dear team, it's cream, water and oil. If refrigerated, it won't. Or there is another similar formula placed on the 1st floor of the house where the weather is not as hot as the 3rd floor. The color will darken more slowly.

Hello, if not exposed to light and the color changes, try adding Anti-oxidant starting from Vitamin E Acetate 0.1% if still not in control You may need to use a stronger one such as Protec™ OX , Protec™ SQ for the separation problem Might have to consider choosing a Stabilizer. If it's an oil-in-water cream, try adding Xanthan Gum slightly 0.2-0.3% or ClayThick 0.5% will solve the problem.

Thanks to the team for the answer. Let me ask a little more if it's Emulsifier like Laureth-23 or Polysorbate 20 (Tween 20) is it stable compared to Xanthan Gum ? Xanthan Gum or ClayThick

Hello, the ingredients that members ask. Is each group Xanthan Gum and ClayThick is not Emulsifier , so the operation is different. So they can't be compared if the formula contains enough and appropriate Emulsifier . And there is still a problem of separating the layers, having to choose to use a helper as recommended because adding more emulisifier It won't help anymore. (Using more Emulsifier will help if the same usage is not yet not enough)

Let me ask you one more time. Protec™ OX with Protec™ SQ here Should be used together or use only one is enough, and if using the above two, then still need to use Vitamin E Acetate ?

Hello, if you use Protec™ OX already don't need Vitamin E Acetate already Protec™ SQ is selected only if Use some active ingredients that are particularly prone to deterioration. For example, a group Vitamin A , Resveratrol (please see product detail page for more details)

This cream is blue in color because of the Copper PCA , in the formula there is วิตามิน E Acetate is 0.1%, if refrigerated, no problem. But if placed in a normal temperature room, it will change the color as you see. In this case, you should only put Protec OX single or enter Protec SQ Go well and if you have to put Protec SQ How many % should I put?

Hello, if you want to know a clear solution, you must first know which ingredients in the formula change color. I suggest members try to test the cause first. that is caused by any substance that changes color
