With Integrity and Quality

Welcome to Churchill, providing a quality, professional service for any project

Churchill PPS is the UK licensee for the patented SingloTex anti-microbial treatment on fabrics and clothing. We also supply Hospital Grade Hand Gel and one time use automotive Sanitiser aerosols to kill bacteria and viruses.

There are different types of microbe:

  • algae
  • bacteria
  • fungi
  • protozoa
  • viruses


Algae (singular: Alga) are unicellular (single-celled) plants which you would normally see in stagnant ponds and pools, and on damp surfaces such as wood and stone-work. The cells are usually green due to the presence of chlorophyll, and these microbes only need light, carbon dioxide and certain minerals to grow. Typical microscopic unicellular green algae are Scenedesmus, Chlorella and Chlamydomonas. The latter is a common inhabitant of ‘green water’ and consists of single, motile, egg-shaped cells about 10 microns long (1 micron, or µm, is 1/1000 of a millimetre). Seaweeds and many pond weeds are larger, multicellular algae.


Bacteria (singular: bacterium) are the most numerous of the microbes and the group most people associate with ‘bugs’ or ‘germs’. They are very small unicellular organisms, usually 1 to 2 µm in length or diameter and are found in almost every environment and associated with all living organisms.

Bacteria were the first disease causing organisms to be identified and are responsible for most human infections, including:

Typhoid – Salmonella typhimurium
Plague – Yersinia pestis
Legionnaires’ disease – Legionella pneumophila
Anthrax – Bacillus anthracis
MRSA – Methicillin-resistant Staphylococcus aureus


Fungi (singular: fungus) are well known to us in the form of mushrooms and toadstools, however the microbiologist is more concerned with the study of moulds, yeasts, mildews and rusts. Fungi are plant-like, growing as ‘threads’ (filaments or hyphae) which usually branch and spread by means of microscopic spores (similar to seeds). However fungi are heterotrophs – they need organic matter to grow and are normally found on decaying materials such as wood, leather etc. The common bread mould Neurospora forms red spores on mouldy bread, as does Aspergillus. Blue-green growth is usually Penicillium and grey growth is Mucor. Penicillium gives the blue colour to Stilton and Gorgonzola cheeses. Yeasts are generally unicellular – and are necessary for fermentation.

Diseases caused by fungi include:

Thrush – Candida albicans
Ringworm – Epidermophyton, Microsporum and Trichophyton species
Pneumonia – Pneumocystis carinii (PCP)

There are relatively few disease-causing fungi, but many moulds produce extremely potent toxins.


Protozoa (singular: protozoon) are the most complex of the microbes and are best regarded as small single-celled animals. Protozoa are heterotrophs, requiring organic food to live and are found in most environments. Protozoa cause relatively few diseases in plants and animals.

Diseases caused by protozoa in man include:

Diarrhoea – Cryptosporidium parvum
Amoebic dysentery – Entamoeba histolytica
Malaria – Plasmodium species
Sleeping sickness – Trypanosoma brucei


The viruses are the smallest microbes, individual virions ranging in size from 0.02 to 0.2 µm long. Unlike other living organisms they display no metabolic functions i.e. they do not feed, respire, communicate or replicate unaided – and there is a debate as to whether they should be classed as living organisms or as stable self-replicating chemical molecules. They can infect plants, animals, humans and even other microbes – and ‘switch’ the metabolism of the host cell(s) to produce many more viruses.

Viruses are associated with many diseases, including

Influenza – Orthomyxoviruses
Smallpox – Variola
Ebola haemorrhagic fever [EHF] – Filovirus
Acquired Immunodeficiency Syndrome (AIDS) – Lentivirus [HIV]
Middle East Respiratory Syndrome (MERS) – Coronavirus
Severe Acute Respiratory Syndrome (SARS) – Coronavirus



SingloTex patented non-toxic dye is applied in a totally aqueous medium and once deposited into the textile fabric it becomes water insoluble and will not leach out.
It then generates an inexhaustible supply of Singlet Oxygen in the presence of natural or artificial light to eliminate any microbes present.
Furthermore, because the dye works catalytically, only a trace amount is necessary for efficient anti-microbial action.

how singlotex works
An overview of how SingloTex works.


The dye first gets excited by light and then transfers some of its energy to the oxygen in the surrounding air.

The oxygen interacts with the energy from the dye and it turns into Singlet Oxygen, which creates o ‘zone of protection’ at the treated surface which kills all microbes.

This process continues 24/7 as the light keeps exciting the dye that is permanently bonded to the surface.

Below is a video of the inventor of SingloTex explaining how he came up with the concept.


An independent report on the efficacy of SingloTex was commissioned in August 2019 from IMSL. The report can be read here.

The testing was carried out in line with ISO 17094:2014. The two test bacteria used are, in lay terms, at opposite ends of the spectrum and so give an acceptable review of performance.

Does the Sanitiser work?

Here’s a testimonial from Mr. White, owner of NDW Engineering:

“I have a storage container which was recently cleaned out of old and unwanted equipment. After the clean out and before putting anything back, I decided to give the Sanitiser a go. Wow! It’s only now that I appreciate just how smelly the container was, presumably from mould and bacteria.

The container now has a new, fresh smell to it, even after a few weeks.

Would I recommend the Sanitiser? Without hesitation.”

Our Services

We work with clients who wish to make use of the SingloTex fabric treatment.

Our Hospital Grade Hand Gel possesses bactericidal activity in one minute at 20*C and is available for retail purchase.

Our Sanitiser aerosol is perfect for cars, vans and lorry cabs to kill the bacteria that create smells. It also kills Coronavirus.



SingloTex treatments of clothing, particularly exercise & sports wear, dance wear, leisure wear and combat uniforms, will help control and eliminate body odour. Because the treatment is permanent, it will continue performing so long as the fabric exists.

Bio-Hazard Protective Suits

SingloTex treatment of biohazard suits will help control and eliminate exposure (intentional or otherwise) to potentially pathogenic microbes. The photo-catalytic agent in SingloTex will produce singlet oxygen – an extremely potent oxidizing agent when treated materials are exposed to light. Scientific studies have shown that singlet oxygen kills a wide range of microbes and has also been shown to degrade highly toxic chemical warfare agents (using simulants for GD, VX and mustard gas) converting them into less toxic compounds.
