SEGUROCERA is inorganic anti-dust mite material that combined boric acid, alkaline earth, silica acid etc. at high temperature, and then pulverized this composition from several µm to several ten µm.
SEGUROCERA doesn't kill mites by volatility substances such as nerve poison used for ordinary organic anti-dust mite material, nor repel mites by volatilizing organic substances which mites dislike.
SEGUROCERA disturbs the moisture balance of mite, and leading them to dry up. It makes mite's reproduction ability weakened, and inhibits their multiplication. As it is inorganic, it has a long time effect against dustmite and does not have hazardous effect to human beings at all.

• Being ceramics, no odor, no volatility
• Enable to compound into resin due to its high heat-resistance
• Long product life and superior in stability during storage
• High level of safety

• The condition of mite multiplication

  Such mites which are apt to cause allergy as D.Pteronissius and T. putrescentiae have a worldwide distribution, and these mites vigorously multiply under the condition at temperature 20℃ to 30℃, higher than 60% R.H. (the best condition is 60 to 80%R.H.)
  They prefer to live close to human living space, especially in carpet, sofa, bedding, stuffed doll and so on, because there are a lot of food for mites such as dirt, dandruff etc., and there are moisturized comfortably by human sweat.

• Influence of mites for human body

  Allergy caused by mites has been a serious problem in the world.
  Especially recent home environment which controlled room temperature in highly sealed house is apt to good condition for mites to multiply through all season. In consequence, house dustmites which consist of mites dead body and their waste has been increasing rapidly in house. This allergen value are higher than other substances, and even a few, these are easily to grow human an allergy as asthma, Rhinitis, Conjunctitis, Dermatitis.

There was no case of abnormal reaction or death by single oral administration of 2000mg/kg of SEGUROCERA to mice

• Acute oral toxicity
  There was no case of abnormal reaction or death by single oral administration of 2000mg/kg of SEGUROCERA to mice
• Primary skin irritation
  No skin irritation response was observed an albino rabbits during or after the skin irritation test suggested in the OECD Chemical Substance Toxicity Test Guidance.(1981)
• Mutagenicity
  The mutagenicity test based on the bulletin No.77 of the Labor Ministry of Japan (1st Sep.1989 )resulted in no increase in reverse mutation and mutagenicity was confirmed to be negative.
• Skin sensitization
  The skin sensitization test using maximization method demonstrated no skin sensitization on guinea pigs.
