-
Manufacturing Suites: Dedicated, hygienic rooms for different product categories (e.g., liquids, powders, anhydrous products). Air filtration systems (HEPA filters) maintain positive air pressure and minimize airborne particles. Equipment is often made of non-reactive stainless steel (304 or 316 grade) and is designed for easy cleaning (CIP – Clean-in-Place systems).
-
Quality Control (QC) Laboratories: On-site labs equipped with instruments like HPLC (High-Performance Liquid Chromatography), viscometers, pH meters, and microbial testing equipment to validate every batch.
-
Filling and Packaging Halls: Automated, high-speed lines that fill, cap, label, and package products with minimal human contact. These areas are often segregated from manufacturing to reduce contamination risk.
The Standardized Production Workflow
A typical batch follows a regimented, documented process:
-
Dispensing: Raw materials are precisely weighed and dispensed in a dedicated area, following a verified formula sheet (master manufacturing formula).
-
Premixing & Heating/Cooling: Oil and water phases are prepared separately, often heated to facilitate mixing, and then combined using precise temperature control.
-
Emulsification: The core step for creams and lotions. High-shear mixers or homogenizers break down droplets to create a stable, uniform mixture of oil and water.
-
Cooling & Addition of Thermally Sensitive Ingredients: Fragrances, preservatives, and active ingredients (like vitamins or peptides) are added once the batch cools to a safe temperature to prevent degradation.
-
Quality Control Check (In-process): Samples are taken to check for viscosity, pH, color, and odor against specifications.
-
Deaeration: Removing air bubbles introduced during mixing to ensure product consistency and aesthetic appeal.
-
Filling & Packaging: Automated machinery fills containers, applies closures, labels, and packs into secondary packaging.
-
Final QC & Release: Finished products undergo final testing (weight check, visual inspection, sometimes stability testing) before being released for shipment.
