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.

Oral care compositions comprising pearlescent pigments

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.

Oral care product

An oral care composition comprising a dye polymer, for modifying the color of teeth.

Oral care compositions comprising a polymeric dye

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, characterized in that the source of calcium ions and the source of phosphate ions are physically separate prior to the use of the product.

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.

Oral bleaching composition

An oral composition comprising picolinic acid and a peroxyl species or equivalent source thereof, characterised in that the molar ratio of picolinic acid to peroxyl species or equivalent source thereof is from 1:30 to 100:1.

Oral composition

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 compounds as teeth whitening/bleaching agents, particularly peroxyamidophthalamides, sulphoperbenzoic acid, monoperoxyphthalic acid, and (per)acetylatedperboric acid with imine quaternary salts as catalysts for the peroxy compounds.

Oral composition with an improved teeth whitening effect

An oral care composition comprises capsules which comprise an encapsulated gent encapsulated by an encapsulating material stable in the presence of anionic surfactants, said encapsulated agent being capable of providing a cosmetic, sensory, protective or therapeutic benefit to the oral cavity, wherein the capsules' weight average particle size ranges from 100 to 2000 .mu.m and wherein the capsules are capable of being gradually crushed during brushing thereby releasing the encapsulated agent gradually during brushing, the foaming capability being maintained throughout brushing.

The present invention relates to anti-microbial cosmetic compositions for the care of the human body or parts thereof, comprising derivatives of histatins or fragments thereof. It has been found that the anti-microbial activity of histatins or their fragments can be significantly enhanced by capping them at the C-terminus or at the C- and N-terminus and/or complexing them with anti-microbially-active metal ions. The thus modified histatins and histatin fragments were found to have a significantly increased activity against a range of microbial strains, and were found to be useful as controlled delivery agents for the metal ions. They are suitable for a whole range of anti-microbial applications, such as anti-plaque, and-caries, anti-bad breath oral applications, deodorant applications, personal hygiene applications and so on, for which they are included in any suitable carrier medium. Preferred are the capped derivatives, which have been complexed with Ag, Cu, Zn or Sn.
