At Guangzhou Dongzhuang Biotechnology, quality is at the heart of everything we do. Every product—from shampoo and conditioner to body wash—is crafted under strict quality standards, using carefully selected natural ingredients. Our skilled R&D team and advanced testing systems ensure that every batch meets international safety and performance requirements. From formulation to final inspection, we maintain rigorous control, guaranteeing consistent, reliable, and premium products for your brand.
We strictly evaluate and select all raw materials, from active plant extracts to surfactants and fragrances, ensuring full compliance with international cosmetic standards. Every batch is accompanied by COA certification and undergoes pre-production testing to guarantee purity and stability.
Throughout mixing, filling, and sealing, every process follows GMP guidelines under a closed, dust-free environment. Our automated systems track temperature, viscosity, and filling accuracy to maintain uniformity and prevent contamination.
Before shipment, each batch undergoes comprehensive testing to ensure safety, performance, and appearance consistency. Only products passing sensory, microbiological, and stability checks are released for distribution.
