Cosmetic products chemical analyzing
During the manufacturing process, cosmetic products need to be chemically analyzed to ensure conforming to product specification and safety regulations, as well as achieving cost-effectiveness in the manufacturing process. Using ED-XRF allows measuring a wide range of elemental concentrations such as C(6)-Fm(100), without a need for sample preparations(heating or destroying the sample). Samples can be measured in the form of loose powders or powders pressed into pellets, and are made ready for measuring within seconds.
ED-XRF can measure larger sample volumes resulting in better characterization of the final products, and provides high accuracy and precision combined with excellent detection limits usually starting 0.1 – 1 mg/kg.
The cosmetic market is most suitable for the ED-XRF method, since many additives in cosmetic products are mineral or inorganic in nature, or organic with add-ons of heavier elements that are measurable by ED-XRF. Xenemetrix Energy Dispersive X-ray Fluorescence (ED-XRF) spectrometers are the simplest, most accurate, non-destructive and economical analytical systems for the cosmetics manufacturing process and its quality assurance.
Several well-known applications include:
- Titanium and Zinc in Sunscreen- Titanium dioxide is used in most sunscreens to help prevent UV radiation burns. The concentration is high and can easily be measured by ED-XRF. Zinc is also used in sunscreens as a UV blocking agent.
- Iron, Titanium, and Zinc in Base Makeup- Flesh colored base makeup usually contain black iron oxide, red iron oxide, and titanium dioxide and/or zinc oxide which are white. The ratio of these oxides determines the shade. ED-XRF has been used to measure total iron and other major components existing in makeup products.
- Toxic Metals in Cosmetics- Cosmetic component are usually analyzed for toxic components to ensure their safety. ED-XRF analyzers can be used for measuring toxic metals such as lead, cadmium, mercury, and arsenic in cosmetic products.
- Metal Dyes in Cosmetics- Some of the brightly colored dyes such as those composing eye shadows and fingernail polishes contain metallic dyes that can be measured by ED-XRF.
Ensure your products safety and regulations conformity with ED-XRF systems!
