摘要:
A production method of novel condensates comprising bisphenols and aromatic aminosulfonic acids, in particular, novel 4-aminobenzenesulfonic acid-2, 2-bis(4-hydrocyphenyl)propaneformaldehyde type condensate and said condensate itself are disclosed. Uses of condensates as a dispersant for disperse dye, additive for carbonaceous fine powder-water slurry and water-reducing agent for cement are also claimed.

摘要:
Provided are an agent for maintaining hardness of tooth substances and a food or drink for maintaining the hardness of tooth substances, both of which include lactoferrin and iron-lactoferrin as an active ingredient. Lactoferrin and iron-lactoferrin suppress decalcification of enamel by use or ingestion thereof, and hence is effective for the prevention of dental caries.
摘要:
It is intended to provide an oral flora-improving agent capable of forming a favorable flora in the oral cavity and a food or a drink for improving the oral flora. An oral flora-improving agent containing as an active ingredient a ganglioside and a food, a drink, or a feed for improving the oral flora containing the ganglioside exhibit an antibacterial effect on harmful bacteria in the oral cavity, which are undesirable from the viewpoint of decay and diseases such as periodontal disease, and a growth-improving effect on useful bacteria to be preserved in the oral cavity. Further, the ganglioside is efficaciously used as an active ingredient in an antibacterial agent or an antibacterial drink, food, or feed, a growth promoter, or a food, a drink, or a feed for promoting growth.

摘要:
It is intended to provide an effective cariostatic material which inhibits dental plaque formation as well as onset of dental carries. A material for inhibiting enamel demineralization containing, as the active ingredient, a proanthocyanidin-like polyphenol originating in hop bract or immature apple, which effectively inhibits not only dental plaque formation but also the dental caries process including proliferation of bacteria, formation of acids by the bacteria and enamel demineralization. Also, foods, drinks and oral care goods with the use of the above substance as an enamel demineralization inhibitor are provided.
摘要:
Provided is a novel lactic acid bacterium strain which is capable of suppressing production of volatile sulfur compounds by oral bacteria, has no cariogenicity and no causative role in infective endocarditis, and is safe in an oral cavity, and provided is an agent for preventing, improving and/or treating oral diseases and discomforts by use of the bacterial strain.An agent for preventing and/or treating an oral disease, containing, as an active ingredient, at least one lactic acid bacterium selected from Lactobacillus crispatus, Lactobacillus fermentum, Lactobacillus gasseri, and Streptococcus mitis and having all of the following properties (1) to (6): (1) having no ability to produce a volatile sulfur compound (VSC); (2) having no ability to produce water-insoluble glucan; (3) having adhesiveness to a tooth surface and/or an oral cell; (4) having a growth inhibitory effect on a bad breath-causing bacterium and/or a periodontal pathogen; (5) having no causative role in infective endocarditis; and (6) having no cariogenicity.
