Please inquire about the use of D&C Red 27 Color Changing Pigment ( CI45410 ). When the color is dissolved in oil, it will be orange. If you want to change the color from orange to clear. How do you do it?

Re: Salt stains on serum bottles

Postby 611438006 » Sat Jun 29, 2024 5:05 pm

Hello, please allow me to ask. Please help the admin answer.

Made 1 serum formula, using Niacinamide 5.5% + Ethyl Ascorbic acid 0.75%, etc.

But now, the formula has salt-like stains clinging to the mouth of the bottle. Some are white, some are creamy. For what reason?

So how can you fix it?

Please ask for advice.

thank you
