What is U-Clean?
U-Clean is designated as the surface cleaning detergent for application
of photocatalytic ARC-FLASH. U-Clean is a highly safe and effective
detergent developed jointly by the Washing System Research and a pharmaceutical
company 18 years ago to clean catheters and dialyzers. It is a new
type of detergent that removes stains more effectively than conventional
detergents. U-Clean generates oxygen when dissolved in water, and
it cleans materials to be coated with the disinfecting photocatalyst.
A detergent for medical use must fulfill various conditions related
to environmental hygiene and wastewater treatment. It must be phosphorus-free,
extremely non-toxic and have high sterilization, bleaching, microbe
decomposition, deodorization and antibacterial effects. U-Clean satisfies
all these conditions. The details are as follows:

Characteristics
• Excellent detergency achieved
by high osmotic and emulsifying effects
• Microbe decomposition that does not adversely affect
wastewatertreatment and is highly advantageous in terms of industrial
pollution
• Excellent disinfection, bleaching, deodorization,
antistatic and antibacterial effects
• Scentless and non-irritating to hands
• Does not damage materials of machinery or equipment
Properties
• Appearance: white, powdery
• Solubility: water-soluble
• Smell: none
• pH: 10.5 (1%)
• BOD: 60 ppm, 0.1% dissolution (JIS K010221)
• N-hexane: less than 0.01 mg/L (undetected)
• SS: less than 1 mg/L (JIS K0102141)
• Foaming force: 32 ml/L water (1% solution, 20ºC)
• Surface tension: 37.4 dyne • cm
(1% solution, 20ºC, DU Nony method)
• Detergency: equivalent to Freon 113 (test data
of Gumma Prefectural Industrial Experimental Station)
• Effective oxygen content: 6%
Toxicity
• Acute oral toxicity of U-Clean is as follows (LD50):
U-Clean: 4,290 - 4,650 mg/kg (mouse) 4,560 mg/kg (rat)
Salt (comparative example): 3,000 mg/kg (rat) according
to JT (Japan Tobacco, Inc.)
Arsenic: undetected Heavy metal: undetected
