Glycerine (also known as glycerol, glycerin, vegetable glycerin) is a viscous liquid additive used in medical simulation to modify gel texture and extend phantom shelf life. When added to gelatin, glycerine increases viscosity, slows dehydration, and creates tissue-like consistency for dissection training.

Alternatives
| Alternative | Best For | Trade-offs |
|---|---|---|
| Gelatin | Base material modified by glycerine addition | Without glycerine: faster dehydration, shorter shelf life |
| Agar | Alternative gel base without need for glycerine | Different texture; plant-based; does not require additive |
| PVA cryogel | Synthetic alternative with inherent durability | More complex preparation; requires freeze-thaw cycles |

Overview
[edit source]Glycerine is a viscous, hygroscopic liquid available as animal-derived (beef/pork byproduct) or plant-derived (vegetable oil-derived). When mixed with gelatin at 5–20% by volume, it increases viscosity, slows dehydration, and creates more realistic dissection resistance. Keep sealed to prevent moisture absorption. Use food-grade glycerine for edible phantoms.
Synonyms
[edit source]Common names: Glycerine, glycerol, glycerin, vegetable glycerin, VG
Chemical: Propane-1,2,3-triol, 1,2,3-propanetriol
Forms: Liquid glycerine, food-grade glycerine, pharmaceutical-grade glycerine, vegetable glycerine, animal-derived glycerine
Regional terms: Glycérine (French), Glicerina (Italian/Spanish), Glycerin (German), Glycerine (Dutch)
Shelf Life & Storage
| Temp Range | Humidity | Surface Reuse | Shelf Life | Spoilage |
|---|---|---|---|---|
| Ambient (15–25 °C) | Sealed container (hygroscopic) | Additive — reuse with fresh base | Multi-year if sealed | Moisture absorption from air if unsealed |
Clinical Context for Simulation
[edit source]Glycerine is a critical additive for extending phantom shelf life and improving tissue-like properties of gelatin-based simulants. Addition of 5–20% glycerine by volume slows dehydration and creates more realistic dissection resistance compared to gelatin alone. This is particularly important for multi-day training courses where phantom consistency must be maintained across sessions.
Processing & Preparation
[edit source]Source: Glycerine available as animal-derived (beef/pork byproduct) or plant-derived (vegetable oil-derived). Verify source for cultural/dietary compliance.
Concentration: 5–20% by volume when mixed with gelatin base.
Mixing: Dissolve glycerine in warm gelatin solution; stir thoroughly to ensure even distribution.
Setting: Gelatin-glycerine mixtures set more slowly than gelatin alone; allow extended cooling time.
Safety Considerations
[edit source]- Source verification — Verify whether glycerine is animal-derived or plant-derived for cultural/dietary compliance.
- Skin contact — Glycerine is hygroscopic (draws moisture); extended skin contact may cause drying.
- Storage — Keep sealed to prevent moisture absorption from air.
- Food safety — Use food-grade glycerine only for edible phantoms.
