Prescriptive oxidant tablets for compact and stable fabric treatment

Overview

AxNano proposes adapting its patent-pending tableted oxidant technology—originally developed for groundwater remediation—into prescriptive fabric treatment products. The tablets use industry-standard oxidizing ingredients such as percarbonate, packaged in a solid form that preserves reactivity until use. By varying the number of tablets added to a wash cycle, consumers can create customized treatment solutions tailored to stain severity and load size. This approach addresses growing demand for effective, easy-to-use, and environmentally conscious laundry products while reducing plastic packaging and shipping weight.

Technical specifications

Key features:

• Tableted oxidant delivery protects reactive ingredients from premature degradation, improving potency and reducing the need for stabilizing additives
• Percarbonate-based formulations demonstrated as effective bleach alternatives against oxidizable stains and organic contaminants
• Prescriptive dosing system allows users to adjust the number of tablets to match stain intensity, fabric type, or wash load size
• Compact solid format significantly decreases product weight and plastic packaging compared to liquid bleach alternatives
• Tunable tablet size and composition enables optimization for different dilution volumes and treatment scenarios
• Scalable manufacturing leveraging existing US-based tablet production infrastructure

Performance validation approach:

• Solutions of varying concentration created from tablets of different sizes and compositions
• Testing in both pretreatment scenarios and full wash loads
• Evaluation using industry-standard methods such as ASTM D4265-21 for stain removal performance
• Stability testing across formulations to optimize the reactive-to-inert fraction ratio
• Screening of additives that enhance stability or improve treatment properties

Technology readiness level

The core tableted oxidant technology has been validated through AxNano's groundwater remediation work, with primary data confirming that tableting preserves oxidant reactivity and enables tunable dosing. Percarbonate efficacy against dyes and organic contaminants is supported by both primary studies and published literature, and percarbonate has a proven track record in consumer bleach-alternative products. The proposed project represents the adaptation of this validated platform to the consumer fabric care market, with planned formulation optimization, performance testing, and stability validation as the next development steps toward commercial readiness.
