Gamma radiation, also known as gamma rays, refers to electromagnetic radiation of extremely high frequencies. Characterized by deep penetration and low dose rates, gamma radiation effectively kills all living cells, including bacteria and microorganisms, throughout a product and its packaging. The process causes little effect on the temperature of the product. Because gamma rays are pure energy, they do not create residues, nor do they have sufficient energy to impart radioactivity. Even high-density products such as heavy, viscous pigments can be processed and used with confidence.
Quantum Cosmetic Pigments is contracted with a third party medical and pharmaceutical industry-leading sterilization company, who specializes in the use of state-of-the-art high-precision irradiators, or gamma rays. After each irradiation process, Quantum Cosmetic Pigments receives a certification verifying the success of the completed irradiation sterilization process. The certifications contain a lot number, which will be noted on each bottle of ink. All of Quantum's products undergo rigorous lab testing procedures for spore, Staphylococcus, Bacillus, Micrococcus, yeast, biological and fungal bioburdens, as well as sterility. No residuals, no radioactivity.
