How to Distinguish High-Purity CoQ10 From Low-Quality Adulterated Raw Materials ？

Coenzyme Q10 Powder, an orange powder, is a strong product of Xi' an Sost Biotech Co., Ltd which is a cosmetic ingredients manufacturer established in 2005. Coenzyme Q10, or more commonly known as Q10, is naturally produced in the body. It is vital for energy production to fulfil the skin's basic functions, such as regeneration and repair, and makes an important contribution to the function of all the body's cells - especially those of the liver, heart and skin. Similar to a vitamin, Q10 is present in the whole body and can support different processes. It plays a vital role in cellular energy production and has antioxidant properties that combat oxidative stress which can accelerate skin ageing and damage the cells. This is why Q10 is so essential for smooth, healthy-looking skin. Until now, the product has been exported to more than forty countries and regions all over the world.

 

How to distinguish high-quality Coenzyme Q10 (CoQ10) raw material from inferior or adulterated versions?

 

1. Verify the Core Purity Index Through Standardized Testing

For adulterated raw materials with diluted components or mixed with analogues, the measured value often deviates far below 98%.It is worth noting that the official standardized detection method will add ferric chloride to the test solution in advance to convert all CoQ10 into a fully oxidized state, so as to avoid the deviation of detection results caused by the mutual conversion of reduced ubiquinol and oxidized ubiquinone. The repeatability relative standard deviation (RSD) of qualified high-purity raw material samples in multi-laboratory collaborative tests is usually lower than 2.5%, and the HorRat index is close to 1, showing extremely stable detection data.

 

Identify Basic Physical and Chemical Characteristics Intuitively
In addition, high-purity CoQ10 is easily soluble in organic solvents such as acetonitrile and tetrahydrofuran, and the solution is clear and transparent after dissolution. If there is obvious turbidity, precipitation or insoluble residue after dissolution, it is mostly adulterated low-quality raw materials mixed with insoluble impurities.

 

3. Trace the Completeness of Test Data and Verification System

Regular high-purity CoQ10 raw materials can provide complete single-laboratory verification and international collaborative study data, including repeatability, accuracy, selectivity, detection limit, quantification limit and linearity inspection reports, and the 8 blind duplicate samples in the collaborative test all meet the deviation control standards.
Adulterated low-quality raw materials often cannot provide a complete traceable test system, and can only provide a single and unsubstantiated purity data. It is impossible to show the full batch of detection records covering multiple dimensions such as raw material incoming inspection, production process monitoring and finished product release. Many of the marked "purity" figures are confused with the finished product mass ratio, and the unit description is confused, for example, the data of 99g per 100g of the finished product is falsely claimed to be 99% of the raw material purity, which is a common false propaganda method of adulterated products.
