Briefings

Earwax is hypothesized to function as an insect repellent due to its unique consistency resembling toothpaste and dough, which can absorb twice its weight in water while remaining sticky. This property has been observed in medieval artists using it as a paint binder, though the specific mechanism for insect repellency remains unproven.

Key points

• Earwax has a consistency similar to toothpaste and dough, capable of absorbing twice its weight in water while remaining sticky.
• Medieval artists used earwax as a binder in paint, though the specific mechanism for insect repellency remains unproven.

Context

Earwax is hypothesized to repel insects due to its unique consistency resembling toothpaste and dough, which can absorb twice its weight in water while remaining sticky. This property has been observed in medieval artists using it as a paint binder.

Limitations

The evidence is limited to historical observations of medieval artists using earwax as a paint binder. The specific mechanism for insect repellency remains unproven, and no quantitative data on repellent efficacy is provided.
