A cosmetic GMP workshop is a clean production facility constructed in accordance with GMPC , the *Code for Design of Clean Rooms*, and relevant national standards for cosmetic safety. Its primary objective is to control variables such as airborne particulates, microorganisms, temperature, and humidity, thereby mitigating the risks of product contamination and spoilage while ensuring regulatory compliance and consistent product quality. Such a facility is a fundamental requirement for cosmetic manufacturers to obtain necessary certifications, engage in large-scale production, and secure contract manufacturing orders. Compared to standard factory buildings, its design and fit-out integrate specialized process requirements, strict cleanliness standards, and safety-oriented functionality.

Organic synthesis laboratories frequently store organic solvents, flammable reagents, and strong acids and bases, creating an environment where volatile, flammable vapors can easily accumulate. Flooring and wall surfaces must not only withstand chemical corrosion but also prevent static electricity buildup while complying with explosion-proof safety standards. The primary construction challenges lie in substrate preparation, material selection, detailing at junctions, grounding systems, airtight installation, and compatibility with long-term operation and maintenance.
