BioGenius determines the droplet and particle size distribution, including MMAD, of your spray products via laser diffraction \u2013 from trigger and pump sprays to spray drift classification for plant protection products. The MMAD value is derived based on laser diffraction and serves as a guiding screening indicator for the respirable fraction. Reliable, GLP-compliant, and regulatorily classified.<\/span><\/h6>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Trigger & Pump Sprays<\/h3>

Real-world spray pattern analysis for deodorants, cosmetics, household products, and biocides.<\/p>

Note: Image placeholder \u2013 insert your own laboratory\/product photography here in the style of the existing BioGenius website.<\/p>

The Risk<\/h6>

A value you cannot see \u2013 but every authority checks.<\/h2>

Whether a spray product works as intended or is classified as hazardous by inhalation is decided within a range of just a few micrometers.<\/p>

Regulatory Uncertainty<\/h3>

Fine spray mists can be classified as inhalation-relevant under CLP\/REACH and the Biocidal Products Regulation. Without reliable droplet size data from laser diffraction, there is a risk of inquiries or re-evaluations shortly before approval.<\/p>

Project Time Pressure<\/h3>

Without early particle measurement, the discovery of a problem is delayed until the most formulation-intensive \u2013 and expensive \u2013 point of the project.<\/p>

Analytical Methods & Validation<\/h2>

We provide support for analytical questions regarding spray products \u2013 using laser diffraction for everything from droplet size distribution and spray drift classification to guiding inhalation screening. If standard approaches are insufficient, we tailor the methodology and test design specifically to your formulation. Analysis can be performed on a project basis under Good Laboratory Practice (GLP) or, as required, under NON-GLP conditions.<\/p>
