Artificial Sebum (BZ539): Description
ASTM D4265-21 Artificial Sebum (BZ539) is a high-quality laboratory-formulated synthetic skin lipid system designed to replicate the composition and behavior of human sebum. It consists of a balanced mixture of fatty acids, triglycerides, wax esters, cholesterol derivatives, and other lipid components that simulate natural skin surface secretions.
It is widely used in dermatological studies, cosmetic formulation testing, textile evaluation, surface fouling studies, and material compatibility research to simulate realistic skin-oil interactions.
Storage and Transportation
Store Artificial Sebum at 2–8 °C to maintain lipid stability and prevent oxidation. The product can be transported at room temperature for short periods without affecting performance. Avoid prolonged exposure to heat, light, or air to preserve chemical integrity and prevent lipid degradation.
Usage Restrictions
This product is strictly intended for research and in vitro laboratory use only. It must be handled by trained professionals in controlled laboratory environments. It is not intended for clinical, diagnostic, therapeutic, or human/animal application.
Safety Precautions
Standard laboratory safety practices must be followed, including gloves, lab coat, and eye protection. Avoid direct contact with skin and eyes. In case of accidental exposure, wash thoroughly with water and appropriate cleaning agents. Dispose of waste according to institutional chemical safety guidelines.
Features & Notes
- Viscosity
Formulated to closely mimic natural human sebum, ensuring realistic spreading, adhesion, and film formation on skin-like and material surfaces.
- Density
Calibrated to represent physiological skin surface lipid behavior for accurate simulation in dermatological and cosmetic testing environments.
- pH Level
pH is not applicable, as Artificial Sebum is an anhydrous lipid-based system. In combined test systems, aqueous phases may be adjusted around pH 5.5–6.0 if required.
- Stability
Stable under recommended storage conditions. Formulated to minimize oxidation and maintain consistent lipid composition throughout shelf life.
- Color
Pale yellow to off-white appearance, closely resembling natural human skin surface oils for realistic visual simulation.
Applications
✔ Cosmetic formulation testing and stability studies
✔ Dermatological research and skin interaction studies
✔ Sunscreen and skincare product performance evaluation
✔ Textile and fabric contamination resistance testing
✔ Surface adhesion and fouling analysis
✔ Medical device skin-contact compatibility testing
Additional Information
This ready-to-use formulation closely simulates human skin sebum for advanced laboratory applications. Optional antioxidant stabilization systems may be included to enhance long-term lipid stability and reduce oxidation.
