Hybrid organic/inorganic capsules as a solution to overcome the microplastic challenge

According to Science, microencapsulation, developed approximately 65 years ago, is defined as a major interdisciplinary research technology. Microencapsulation is being used to deliver everything from advanced drugs to unique consumer sensory experiences. It’s rapidly becoming one of the most important opportunities for expanding brand potential. Current advances in polymer science and inorganic chemistry have further enhanced this growth. However, current capsules based on non-degradable polymers generate microplastics. The market for cosmetics and home care products in general is not alien to this problem. Due to the presence of ingredients carried through polymeric microparticles they are also affected by the restriction of the European Chemicals Agency (ECHA). To overcome the microplastics challenge in cosmetic and consumer goods, scientists from Eurecat and CARINSA have developed a new generation of biodegradable capsules formed by organic/inorganic materials. These novel capsules possess a compact structure which prevents any leakage of the encapsulated active. Recently, this technology has been protected with a patent application to the European Patent Office. Generated results protected in this patent will be the subject of the presentation.
