Deeptech start-up Sparxell has raised $5m (£4m) in pre-Series A funding to scale its plant-based colour technology. The company aims to replace synthetic colourants with its bioinspired materials.
SWEN Capital Partners’ Blue Ocean 2 fund led the investment, with Alpha Star Capital and Cambridge Enterprise also participating. This capital will enable Sparxell to move from pilot projects to commercial production, with tonne-scale facilities planned for 2026.
Sparxell's patented method uses cellulose from wood pulp. It creates structural colour by reflecting light wavelengths, mimicking butterfly wings. This process avoids petroleum-based chemicals, synthetic dyes, heavy metals, and microplastics. It also claims to reduce water usage by up to 90%.
The technology has applications across textiles, cosmetics, packaging, food, automotive, and coatings. Crucially, it is designed to be compatible with existing manufacturing systems. This ease of integration will be key for adoption.
The funding follows a strong year for Sparxell. It secured a €1.9m European Innovation Council grant. It also completed commercial validation projects, including work with fashion brand Patrick McDowell.
The push for greener ingredients and reduced chemical footprints is gaining momentum. Sparxell's technology offers brands a viable, high-performance alternative. It supports sustainability goals without compromising commercial needs, a critical balance for beauty businesses.
