The present invention relates to an oral care composition, which contains the following components (A), (B) and (C):

Compositions for mouth containing an anionic surfactant having reduced astringency

The invention provides an oral preparation or a chewing gum comprising an organic acid and/or inorganic acid and a fluoride ion supplying compound, wherein a light scattering layer is formed inside enamel of the teeth when the oral preparation or the chewing gum is applied to teeth. An internal tooth colored layer in the enamel is masked by the light scattering layer, and a white appearance is imparted to the teeth.

Oral preparation and chewing gum

A framed soap composition comprises (a) from 20 to 50% by weight of a fatty acid soap, (b) from 1 to 15% by weight of a nonionic surfactant, and (c) from 0.1 to 5% by weight of an inorganic salt. A framed soap composition incorporated with air bubbles is produced by melting a mixture containing these components while heating the mixture in the presence of water, subjecting the resultant molten material to aeration treatment to incorporate air bubbles, and pouring the resultant molten material incorporated with air bubbles, into a frame followed by cooling to harden the molten material.

Framed soap composition containing non-ionic surfactant and inorganic

A method for improving the foaming property of a nonionic surfactant having a straight-chain alkyl group containing from 10 to 16 carbon atoms, and an HLB value of about 13.5 or more is disclosed, which comprises adding (b) a fatty acid monoglyceride represented by formula (I):

Method for improving foaming properties and foaming composition

A surfactant composition containing a fatty acid polyoxyalkylene lower alkyl ether represented by formula (1):

Foaming surfactant composition comprising fatty acid polyoxyalkylene

A detergent composition comprising a polyether-modified silicone having a molecular weight of 3,500 or smaller as a detergent component is disclosed. The detergent composition can effectively eliminate oily residue such as the residues from makeup, e.g. lipsticks, foundations, etc., sebum, and the like in a short period of time, while imparting a pleasant sensation to the skin during and after cleansing.

Detergent composition

A colloidal solution comprises a fluoride(s) being difficultly soluble in water comprises colloidal particles of the fluoride having a particle size of 0.005 to 1 micron, said fluoride having a fluoride ion concentration of 1 to 10,000 ppm in the state of saturation.

Fluoride colloid and oral composition

A colloidal solution comprises a fluoride(s) being difficultiy soluble in water comprises colloidal particles of the fluoride having a particle size of 0.005 to 1 micron, said fluoride having a fluoride ion concentration of 1 to 10,000 ppm in the state of saturation.
