I. Definition and Characteristics of Emulsion Cosmetics
1. Product Definition
An emulsion is a semi-fluid system formed by the emulsification of an aqueous phase and an oil phase. Its viscosity is between that of a toner (<100 mPa·s) and a cream (>100,000 mPa·s). Typical characteristics:
Physical state: Flowable but not dripping at room temperature (viscosity 1,000-50,000 mPa·s)
Structural type: Oil-in-water (O/W, refreshing type) or water-in-oil (W/O, moisturizing type)
Failure Risks: Delamination/Oil-Water Separation (Shock/High Temperature), Active Ingredient Oxidation (Oxygen Permeation), Moisture Evaporation (Insufficient Sealing)

VC Antioxidant Emulsion → Amber Glass Bottle + Vacuum Pump (Light Protection + Oxygen Insulation)
Children's Moisturizing Lotion → HDPE Bottle + Anti-Backflow Pump Head (Contamination Prevention)
Pure Beauty Emulsion → Sugarcane-Based Plastic Bottle + FSC Certified Cardboard Box
III. Core Points and Risk Control for Emulsion Packaging Material Procurement
Four Rigid Indicators for Procurement Decisions
IV. Summary
When procuring emulsion packaging materials, early intervention is crucial, such as participating in the packaging material selection during the formulation development stage (to avoid incompatibility between highly active ingredients and plastics); technical support is essential, such as requiring suppliers to provide triple verification (compatibility + functional testing + shelf-life simulation); in terms of cost, TCO can be used to calculate the true cost (e.g., 8% loss rate for low-priced tube filling vs. high-priced vacuum pumps 3%); at the same time, a backup supply chain plan should be prepared, and more than two certified suppliers are required for key components (pump head springs, valves).
