Cleanrooms in the cosmetics industry are more than sterile spaces—they are controlled environments designed to protect product integrity and ensure consumer safety.

The required level of cleanliness varies based on product formulation and intended use. For instance, eye-care products or formulations with high water content demand stricter contamination control. While ISO Class 8 (Class 100,000) cleanrooms are commonly used, more sensitive products may require ISO Class 7 (Class 10,000) or even ISO Class 5 (Class 100) environments to meet stringent quality standards
