Biopolymer-based controlled release of fragrance and volatile oils
This innovative solution leverages biodegradable biopolymer-based microparticles for the controlled release of volatile fragrance and essential oils in topical formulations. By utilizing alginate-based crosslinked microparticles, this technology enhances fragrance retention and prolongs scent intensity, addressing key challenges in volatile fragrance systems such as rapid evaporation and instability.
Overview
Biopolymer-based controlled release technology offers a novel approach to stabilizing and controlling the release of volatile fragrance and essential oils in various topical formulations. By employing biodegradable alginate-based microparticles, this solution reduces rapid volatilization and improves fragrance retention, thereby prolonging scent intensity. Encapsulation protects the volatile compounds from evaporation, oxidation, and phase separation, while allowing sustained diffusion through controlled swelling and matrix relaxation. This technology supports high fragrance oil loading (>10%) and is compatible with diverse application formats such as creams, ointments, roll-ons, sticks, and sprays.

About Makabi Agritech
Makabi Agritech is a Croatian agritech company that has developed a proprietary 3-in-1 encapsulation technology for sustainable agricultural production. Utilizing green chemistry, the company creates biodegradable, bio-based microcapsules that combine plant protection, nutrient delivery, and the controlled release of bioactive components. This innovation is designed to replace traditional synthetic agrochemicals, with the goal of reducing environmental pollution, mitigating the impacts of climate change, and enhancing the biopotential and nutritional quality of food crops. The technology works by introducing microcapsules into the root zone or applying them to plant parts, where they dissolve to provide essential nutrients and protection precisely when needed. Founded in 2019 following research at the University of Zagreb, the company focuses on advancing sustainable farming practices through science-based innovations.
This technology is significant for the agricultural sector as it offers a scalable, eco-friendly alternative to conventional fertilizers and pesticides, potentially reducing agrochemical usage by up to 30 percent. By improving soil health and promoting the production of functional, safer food for human consumption, Makabi Agritech addresses critical global sustainability goals, including zero hunger and responsible consumption. The company actively engages in research and development collaborations, participates in international innovation challenges, and has received recognition and funding for its contributions to sustainable chemistry. Its solutions have been tested on various crops, including strawberries, tomatoes, and tobacco, in both field and greenhouse environments.
