Extending the disinfectant effect in swimming pools for a major residential pool company

A major company in the residential swimming pool sector was looking for a development to extend the disinfectant effect in pools. The aim was to make the use of chlorine tablets more effective.

01. CHALLENGE

The main challenge in this project was to find a way to encapsulate a disinfectant agent to prolong its effect when exposed to water.

The starting point for developing this new product was disinfectant tablets. Once in use, these tablets had to meet legal specifications, so the active ingredient had to be released in a controlled way and always within legal limits.

The encapsulation proposed by GDE had to offer high resistance to organic compounds and stability for up to five years, maintaining the product’s properties and improving its performance in its final function.

The goal was a functional product specialised in dosing the disinfectant agent, keeping the total chlorine concentration in the medium under control at all times.

02. SOLUTION

Microsponges were used to solve this challenge. Microsponges are microspheres of a material with a large number of internal pores, through which they can absorb different active ingredients or components.

Thanks to the length of these pores, the absorbed substance is deposited along the pore, so that it is released continuously when exposed to water. The substance on the surface is released first, followed gradually by the rest, down to the bottom of the pore.

An encapsulation study of the selected disinfectant agent was carried out, considering its formulation and the preservation of the product’s properties once active.

Thanks to their porosity, the microsponges developed made it possible to regulate the disinfectant agent’s exposure to the medium. This showed that the active agent is protected from the surrounding medium by the microsphere wall.

03. TODAY

A major company in the residential pool sector now has an innovative solution to include in its product, with longer-lasting properties that guarantee antiseptic properties in pool water while complying with current regulations.
