摘要:
The present invention relates to oral care compositions with an improved teeth whitening effect. This effect is achieved by inclusion in the oral care compositions of certain organic peroxy acids as teeth whitening/bleaching agents, particularly peroxyamidophthalamides together with hydrogen peroxide.

摘要:
An Oral care product is provided which includes a mesoporous calcium silicate biomaterial (MCSB) dispersed in a polymeric material matrix. MCSB is an insoluble composite material of calcium oxide-silica.
摘要:
An oral care composition comprising from 0.01 to 0.3% by weight of a pigment having a hue angle, h, in the CIELAB system of from 220 to 320 degrees, characterized in that the composition further comprises a soluble deposition aid for said pigment.
摘要:
An oral care product comprising a source of calcium ions, a source of phosphate ions, and an insoluble whitening agent for deposition onto the teeth, characterised in that the source of calcium ions and the source of phosphate ions are physically separate prior to the use of the product.
摘要:
An oral care product comprising a first composition comprising an insoluble calcium salt that is not a calcium phosphate salt, a second independent composition comprising a source of phosphate ions, and a means for delivering each of the compositions to the surface of the teeth.
摘要:
The invention provides an oral care composition suitable for delivering a temporary whitening effect to the surface of teeth, the composition comprising: a continuous phase comprising water or polyhydric alcohol or a mixture thereof; a tooth surface whitening agent which is dispersed in the continuous phase, and a deposition aid for the tooth surface whitening agent; characterized in that the tooth surface whitening agent is a pearlescent pigment in an amount of at least 0.1% by weight based on the total weight of the composition, the pearlescent pigment being formed by coating one or more metal oxide layers onto particles of an inorganic substrate.
