Biodegradable biobased microcapsules for sustainable dry laundry formulations

Overview

Calyxia has developed a customizable microencapsulation technology that produces biodegradable and biobased microcapsules tailored for dry laundry formulations. Conventional laundry microcapsules contribute to microplastic pollution, creating an environmental challenge for the industry. Calyxia's solution addresses this by enabling powder or pod-based products that protect and release active ingredients in a controlled manner, supporting brands in reducing packaging waste and advancing their sustainability commitments.

The technology is designed to encapsulate ingredients such as optical brighteners, enzymes, and protective agents, allowing formulators to transition from liquid to solid formats without compromising performance. By combining clean ingredients with reduced packaging, the overall environmental footprint of laundry products is significantly improved.

Technical specifications

Key features of Calyxia microcapsules:

• Monodisperse and size-controlled particles for consistent performance
• Non-porous or porosity-controlled shells to manage release profiles
• Compatible with a wide range of shell materials, including biodegradable and biobased options
• Customizable encapsulation for diverse active ingredients

Validated performance:

• Readily biodegradable according to OECD 301 B and OECD 301 F standards, achieving greater than 60% biodegradation in 28 days
• Proven long-lasting effect and controlled delivery through confidential client programs in Home and Personal Care, Agriculture, and Advanced Materials
• Formaldehyde-free composition aligned with clean-label trends

Research collaboration phases:

• Phase 1: Define partner specifications, screen Calyxia's shell chemistry library, tailor physicochemical properties, produce three prototypes, and conduct partner-led performance testing
• Phase 2: Optimize the most promising prototype for release behavior, drying, and dry formulation integration

Technology readiness level

Calyxia's microencapsulation technology is commercially validated across multiple industries including Home and Personal Care, Agriculture, and Advanced Materials. The core platform has demonstrated biodegradability certification and proven performance in client-specific applications. The proposed research focuses on adapting existing technology to laundry-specific dry formulations, progressing through prototype development and lab-scale optimization before scaling toward commercial deployment. This positions the solution at an advanced readiness stage with established proof of concept and active development toward market-ready laundry applications.
