Cosmetics Formulation Development

Hello, I would like to ask if the company has a service to check the amount of Retinal from creams that are made to order.

I want to test if after using the cream for 6 months, is there still some amount of Retinal left?

thank you

hello

It's HPLC work.

HPLC (UHPLC-DAD) Quantitative Analysis

Order and pay for 2 samples sent.

1. Cream sample 5 grams

2. Sample Retinal 1 gram

If in the case of cream used to test Will I have to buy a 1 gram sample of Retinal-EZ ™ (Encapsulated Water Dispersible Retinal )?

Standard Reference must use pure Retinal , not Retinal emulsion.
