    • This invention relates to a use of a composition for protecting oral cavity and teeth containing ethyl-Nα-lauroyl-L-arginate HCI (LAE), a corresponding composition and a corresponding method for protecting teeth. Because of nearly epidemic incidence of dental erosion, there is a continuing need for improved products that provide protection against dental erosion. Hence, it is an object of the present invention to protect teeth against dental erosion. Surprisingly, it has been found that ethyl-Nα-lauroyl-L-arginate HCI (LAE) and its salts attach to teeth and provide protection of teeth from erosion especially caused by the action of acid in food products and drinks such as chewing gum and lozenges compositions. Special advantages of this invention are: (a) sustained coating of the teeth by LAE and its homologues; (b) the coating agent provides a source of neutralizing plaque acids by providing sustained base formation. This is because arginines in LAE is degraded by bacteria on tooth in the mouth to produce ammonia. Thus, this chemistry not only provides the coating protection but also generates base to maintain pH balance on a sustained basis; and (c) avoid the use of brushing with abrasive cleansers.
    • 本发明涉及用于保护含有月桂酰-L-精氨酸乙酯钠盐(LAE)的口腔和牙齿的组合物的用途,相应的组合物和相应的保护牙齿的方法。 由于牙齿侵蚀发生几乎流行,因此继续需要提供防止牙齿侵蚀的改良产品。 因此,本发明的目的是保护牙齿免受牙齿侵蚀。 令人惊讶的是,已经发现乙基 - 月桂酰-L-精氨酸盐酸盐(LAE)及其盐附着在牙齿上,并且保护牙齿免受侵蚀,特别是由于酸在食品和饮料中的作用引起的,例如口香糖和 锭剂组合物 本发明的特殊优点是:(a)通过LAE及其同系物持续涂覆牙齿; (b)涂层剂通过提供持续的碱形成提供中和斑块酸源。 这是因为LAE中的精氨酸被口腔中的牙齿上的细菌降解以产生氨。 因此,这种化学不仅提供了涂层保护,而且还产生了基础,以持续地维持pH平衡; 和(c)避免使用磨料清洁剂进行刷牙。
