Novel morpholino compounds having the general formula ##STR1## wherein R.sub.1 is a straight or branched alkyl group containing 8 to 16 carbon atoms at the 2- or 3-position of the morpholino ring, and R.sub.2 is a straight or branched alkyl group containing 2 to 10 carbon atoms, substituted with a hydroxy group except in the alpha-position, the sum of the carbon atoms in the groups R.sub.1 and R.sub.2 being at least 10 and preferably 10 to 20; and pharmaceutically acceptable salts thereof. Compositions for the treatment of the oral cavity and especially the tooth surfaces containing the novel compound or a salt thereof, preferably from 0.1 to 5% by weight thereof. Use of the compounds to inhibit the formation of dental plaque or remove plaque already formed by application of the compound in an aqueous solution or a composition to the surfaces of the oral cavity, especially the surfaces of the teeth. Processes for the preparation of the compounds.
具有一般式##STR1##的新型吗啡啶化合物,其中R.sub.1是在吗啡啶环的2-或3-位置含有8至16个碳原子的直链或支链烷基基团,R.sub.2是含有2至10个碳原子的直链或支链烷基基团,除α-位置外被一个羟基取代,基团R.sub.1和R.sub.2中碳原子的总和至少为10,最好为10至20;及其药用可接受的盐。含有该新型化合物或其盐的用于治疗口腔,特别是牙齿表面的组合物,其重量百分比优选为0.1至5%。使用这些化合物抑制牙菌斑的形成或通过将该化合物以水溶液或组合物的形式应用于口腔表面,特别是牙齿表面,来去除已经形成的牙菌斑。制备这些化合物的方法。
