Biodegradable Particles (BIO EF-A Series)
Overview
We have developed a new biodegradable particle that complies with the microbeads regulation*.
The particles biodegrade over time in water due to bacteria unlike conventional resin particles and can be alternative raw material to meet the microbeads regulation.
*ECHA Microplastic Beads Regulation Proposal
Features
- (1) Micron sized particles composed from biodegradable resin.
- (2) No problems with skin sensitivity and irritation to eyes. (* Measurement in Vitro)
- (3) Highly degradable in water.
- (4) Superior light reflection compared to spherical particles and soft focus effects are expected.
- (5) Shows more lipophilicity than other natural alternatives.

Evaluation of Biodegradability
High degradability in water (Degraded 60% in 28 days.)
Evaluation of light reflection performance
A black reflection plate with the particles applied were measured to confirm the light reflection distribution with the incident light illuminated at -45°.
The BIO EF-A has a higher soft focus effect than standard spherical particles.
