Description

The present invention relates to a liquid oral composition in a foam dispensing container.

A liquid oral composition filled in a container capable of expelling the contents in a foamy form can be applied in a foamy form from the ejection port into the oral cavity at the time of use, and can be easily adhered to the tongue and mucous membranes. In addition, many users like it because it is easy to spread to every corner of the oral cavity. On the other hand, it is also known that if menthol is added to a liquid composition for oral cavity, it brings about a good flavor and feel during use.

For example, Patent Document 1 discloses a liquid oral composition containing a specific amount of a nonionic surfactant while maintaining a specific mass ratio of a fragrance such as menthol and an amphoteric surfactant. Attempts have been made to stably contain a large amount of perfume. Further, Patent Document 2 discloses a liquid oral composition in a foam discharge container containing specific amounts of an alkyl galacside, a lactone compound, and a cooling sensation agent such as L-menthol. It is possible to effectively mask off-flavours derived from alkyl galacsides and to prevent the flavor of lactone compounds from being felt strongly.
