Artificial Eccrine Sweat-Sebum Emulsion BZ118
Product Code: BZ118
Manufacturer: Biochemazone
Available Pack Sizes: 100 mL, 200 mL, 500 mL, 1 L
Custom Bulk Quantities Available
Product Overview
Biochemazone Artificial Eccrine Sweat-Sebum Emulsion BZ118 combines artificial eccrine sweat and artificial sebum in a single ready-to-use emulsion. On real skin, watery sweat and oily sebum are always present together, and it is this mixture – not sweat alone – that is transferred to a surface by touch. BZ118 reproduces that mixed film for corrosion-resistance and alloy studies and for handling tests on touch surfaces.
The aqueous phase consists of amino acids, minerals and metabolites that simulate the composition, properties and pH of human eccrine sweat; oleic acid acts as the emulsifying agent for the sebum phase. Two variants are supplied: an oil-in-water emulsion (95% water, 5% oil) and a water-in-oil emulsion (95% oil, 5% water). State the variant you need in the order notes or by email. Preservative, stabilizer, antifungal and antibacterial agents are added to protect the emulsion; custom-pH versions are available.
BZ118 is used by manufacturers of metal alloys, platings, coatings, consumer electronics and wearables to test resistance to fingerprints and prolonged skin contact. For sweat alone see Artificial Eccrine Perspiration BZ110; for sebum alone see ASTM D4265-14 Artificial Sebum BZ117; for a particulate-loaded version see Dusty Sweat-Sebum Emulsion BZ616.
Key Features & Benefits
✅ Sweat and Sebum in One Emulsion – Reproduces the mixed film that skin leaves on a touched surface
✅ Two Variants – Oil-in-water (95% water / 5% oil) or water-in-oil (95% oil / 5% water)
✅ Stabilized – Preservative / stabilizer system protects the emulsion
✅ Ready to Use – No separate preparation and emulsification of sweat and sebum
✅ Reproducible & Standardized – Consistent batch-to-batch composition for routine QC and inter-laboratory comparison
✅ Made in Canada – Manufactured under ISO 9001 / GMP quality systems

Frequently Asked Questions
Which variant should I choose?
Choose the oil-in-water emulsion (95% water, 5% oil) when you want a mainly aqueous sweat carrying a little sebum, as on freshly sweating skin. Choose the water-in-oil emulsion (95% oil, 5% water) for a mainly oily film, as in fingerprint residue on a touch surface.
Does the emulsion separate on standing?
Emulsions can cream or separate during storage. Shake the bottle well before each use to restore a uniform emulsion.
