Vitamin C Ethyl Ether Ascorbic Acid Color and Salicylic Acid Formulation Without Stabilizer

Asked by: peerapon_n On: March 16, 2013 Product Type: Cosmetics

Question

I recently received Vitamin C Ethyl Ether Ascorbic Acid powder which is a light brown color. The website description said it should be a white powder. Is the light brown color normal, and is the product still safe and effective to use in cosmetic formulations?

Additionally, I purchased Salicylic Acid for exfoliation but forgot to order a stabilizer (like Polysorbate 20) to prevent precipitation after mixing. If the Salicylic Acid precipitates, can I just shake the mixture before use, and will it be as effective as a formula that includes Polysorbate 20?

Answer

Information Regarding Your Order and Product Questions

Thank you for your inquiry regarding your recent order and product questions.

Missing Vitamin C Ethyl Ether Ascorbic Acid

We sincerely apologize for the missing bottle of Vitamin C Ethyl Ether Ascorbic Acid from your order. Our dispatch team has already sent out the missing item today.

Color of Vitamin C Ethyl Ether Ascorbic Acid

Regarding the color of the Vitamin C Ethyl Ether Ascorbic Acid powder, we apologize for the incorrect information on our website. Ethyl Ascorbic Acid is naturally a light yellow powder, not white. The product you received with a light brown color is normal and still safe and effective to use in your cosmetic formulations.

Using Salicylic Acid Without Polysorbate 20

You asked about using Salicylic Acid without a stabilizer like Polysorbate 20 and if shaking the mixture when it settles would give the same results. The effectiveness will be very close, especially if your formulation base contains 20-40% Propylene Glycol. In this case, you can simply shake the mixture before each use. However, if your formulation is purely water-based, the effectiveness will be significantly reduced without a proper solubilizer or stabilizer.
