Better hygiene outcomes at lower temperatures — without complicated wash chemistry.
ZeroBac is a cold-wash laundry hygiene platform developed for healthcare and institutional laundries. It is built to help laundries reduce bioburden in a more energy-efficient way, supporting sustainability targets while maintaining robust hygiene standards.

The problem we solve
Hygiene • Cost • SustainabilityInfections are expensive
Hospital acquired infections increase length of stay, bed blocking, and cancelled procedures — with serious patient outcomes.
- Pressure on capacity
- Operational disruption
- Reputational risk
Heat costs money
Hot wash programs drive energy cost and emissions, while complex chemical stacks increase handling and wastewater concerns.
- Higher utility bills
- Higher carbon footprint
- Process complexity
Reuse is rising
Healthcare systems are emphasising reuse and laundering over single-use items — increasing laundry volume and hygiene scrutiny.
- More textiles to process
- Higher hygiene expectations
- Need for repeatability

- Institutional scale
- Repeat purchasing model
- Consumer-ready pathway
3) Biocidal Rinse
A rinse-stage option for programs that require an additional hygiene step or where process constraints call for a dedicated rinse treatment.
- Flexible integration

- Designed for laundries
How it works
Two-part active systemTwo complementary actions
ZeroBac uses a two-part approach designed to support immediate reduction and ongoing residual action (subject to validated test conditions):
- T99-19: long-term kill with residual disinfection
- Instant disinfection: rapid action component
Exact formulation and claims depend on jurisdiction and approved data sets.
Dilution & dosing
Added to water at typical ratios ranging from 50:1 to 200:1 (water is the larger number), enabling cost-effective dosing at scale.
- Designed for commercial laundry workflows
- Works with established SOPs
- Training materials available
Dosing is finalised during rollout based on program design, linen load, and required hygiene outcomes.
De-risked development
6+ years of workIn controlled testing, ZeroBac has demonstrated up to 99.9945% reduction in target organisms under defined conditions. Detailed reports, methods, and scope are available on request.
Important: final market claims vary by country and must be substantiated and compliant with local biocidal / antimicrobial regulations.
Team & partners
Industry + NHS expertiseUpon purchase of an initial 10 tonnes of active, Sanitized will grant worldwide distribution rights for laundry on the main active. We aim to purchase 30 tonnes for optimal pricing.

What we’re raising
We are raising £500k–£1.5m to purchase initial stock (10–30 tonnes in tranches), complete registrations, organise packaging, and launch PR/rollout.
- Registrations: ~10 days (FR/DE/GB) once dossiers are ready*
- Packaging: formats for institutional laundries
- Go-to-market: pilots → reference sites → scale
*Timelines depend on submission readiness and jurisdictional requirements.
