  • Patent number: 9687435
    Abstract: It is intended to provide a liquid oral composition and a liquid food composition in which calcium phosphate such as hydroxyapatite or tricalcium phosphate can be stably dispersed and prevented from being precipitated or separated out even in long-term storage. Calcium phosphate mixed with xanthan gum and polyglycerin fatty acid ester can be stably dispersed even in long-term storage and prevented from being precipitated or separated out even when used in liquid oral compositions such as mouthwashes, liquid dentifrices, and oral detergents or in liquid food compositions such as milk, soy milk, yoghurt, and refreshing beverages. In addition, calcium phosphate mixed with xanthan gum and polyglycerin fatty acid ester further supplemented with an amphoteric surfactant can be more effectively prevented from being precipitated or separated out in liquid oral compositions such as mouthwashes, liquid dentifrices, and oral detergents.
