Application

Application of Vegetable Carbon Black

Vegetable carbon black is natural food coloring agent, it is mainly used in bakery products, cheese, frozen food products, food coating and so on. It can be used together with other food coloring agents to increase the color intensity. It can also be used in cosmetics and pharmaceuticals.Silicon rubber: Improve anti-aging property and resilience Plastic industry: Can improve the flexibility, strength and water resistance of plastics. Coatings: Enhance anti-caking property; Has thickening and extinction property. Pharmacy: Has thickening, suspending function; As carrier; As anti-caking agent.
