The personal care product manufacturing industry involves complex production processes that require strict adherence to control levels to maintain product quality. Even minor variations can lead to sub-par products, affecting the reliability, performance, and ultimate market reception of the products. In such scenarios, Statistical Process Control (SPC) becomes an indispensable tool for: Monitoring critical quality variables (e.g., viscosity, pH, temperature). Detecting abnormal variances before they lead to quality defects. Enhancing consistency across production batches.
