    • The present invention relates to a method for cleaning dentures, and more particularly to a method comprising immersing the denture in an aqueous bath comprising a surfactant or mixture of surfactants including at least 0.1 % non-ionic surfactant, the bath having a cloud point of from 45 DEG C to 95 DEG C, heating the bath to a temperature above the cloud point, for example by microwaving, and thereafter cooling the denture to a temperature below the cloud point. The method provides improved plaque removal. The invention further relates to a denture receptacle comprising from 30 to 300 mls aqueous bath comprising a surfactant or mixture of surfactants, the bath having a cloud point of from 45 DEG C to 95 DEG C and comprising at least 0.1 % non-ionic surfactant and further having a denture immersed therein. The invention yet further relates to liquid cleaning concentrates comprising hydrogen peroxide and a mixed non-ionic/anionic surfactant system for practising the methods of the invention.
    • 本发明涉及一种用于清洁义齿的方法,更具体地涉及一种方法,包括将义齿浸入含有表面活性剂或表面活性剂的混合物的水浴中,所述表面活性剂包括至少0.1%的非离子表面活性剂,所述浴的浊点为 45℃至95℃,例如通过微波加热浴至高于浊点的温度,然后将义齿冷却至低于浊点的温度。 该方法提供改进的斑块去除。 本发明还涉及一种义齿容器,其包含30至300ml含有表面活性剂或表面活性剂混合物的水浴,该浴的浊点为45℃至95℃,并且包含至少0.1%的非离子表面活性剂和 还具有浸入其中的义齿。 本发明还涉及包含过氧化氢和用于实施本发明方法的混合非离子/阴离子表面活性剂体系的液体清洁浓缩物。
