A desensitizing anti-tartar dentifrice of low stringiness upon extrusion from a tube or other container onto a toothbrush is provided which also retains desirable cream or gel consistency without becoming thick and difficult to extrude and retains phase integrity without substantial separation, which contains polyphosphate or phosphono compound anti-tartar agent and potassium salt tooth pain inhibitor and in which the gelling agent is a mixture of alkali metal carboxymethyl cellulose, (CMC) and xanthan, wherein the CMC contains about 1.0 to 1.5 carboxymethyl groups per anhydroglycose unit.

Stable desensitizing antitartar dentifrice

The invention provides a substantially nonirritating oral composition containing a surfactant system comprised of a combination of an anionic surfactant, an amphoteric surfactant and a nonesterified alkyl polyglucoside surfactant.

Oral composition containing an anionic, a nonionic and an amphoteric

A striped dentrifrice stable color bleeding, wherein at least one component contains a colorant entrained in the matrix of substantially non-fracturable, partially cross-linked melamine-urea-formaldehyde condensation polymer particles, whereby on storage the colorant does not bleed any color into any other dentifrice component. The dentifrice may also contain a formaldehyde scavenger to bind-up any formaldehyde released from the particles.

Striped dentifrice stable to color bleeding

An extrudable composite multilayer dentifrice composition for cleaning teeth containing reactive bicarbonate and peroxide ingredients which do not interact during storage or when extruded together from a container onto a toothbrush but react in the oral cavity when mixed during tooth brushing, the composition comprising two separate dentifrice components, one component containing a peroxide ingredient and the other component containing a colorant reactive with the peroxide ingredient, the components having substantially equivalent viscosity which are maintained in stable discrete layered phases in interfacial contact with each other prior to extrusion without interaction of the peroxide and the colorant and which are extrudable together in interfacial contact without interaction of the ingredients.

Multilayer bicarbonate/peroxide dentifrice

A dentifrice composition containing reactive ingredients such as peroxide and bicarbonate compounds which are stabilized to decomposition during storage by incorporating in dentifrice composition about 1.0 to about 5.0% by weight of an alkali metal compound.

Stabilized dentifrice compositions containing reactive ingredients

A cosmetically and therapeutically stable antiplaque dentifrice comprising a combination of hexetidine, a soluble zinc salt and a fluoride compound capable of providing a fluoride ion, as the antiplaque agent in dental vehicle containing a polyethylene glycol humectant and a dental abrasive.

Stable antiplaque dentifrice based on hexetidine, zinc ion and fluoride

A dentifrice composition of desirable rheological properties suitable for efficient filling into a mechanically operated or pressure differential dentifrice dispenser and extrusion therefrom which dentifrice comprises an alpha-alumina trihydrate polishing agent and many active ingredients and a gelling agent mixture of a cellulosic gelling agent such as sodium carboxymethyl cellulose and iota-carrageenan.

Dentifrice composition

A stable antiplaque dentifrice with improved foaming containing an antiplaque quaternary ammonium compound, a betaine surfactant to improve foaming without inactivating the antibacterial and antiplaque activity of the quaternary ammonium compound, a humectant selected from the group consisting of polyethylene glycol, sorbitol and mixtures thereof, and a nonionic gelling agent, preferably hydroxyethylcellulose, in an aqueous vehicle containing a dental abrasive. A fluorine-containing compound such as monofluorophosphate is an optionally preferred ingredient.

Stable antiplaque dentifrice with improved foaming

A stable antiplaque dentifrice with improved foaming and improved fluoride stability containing an antiplaque quaternary ammonium compound, a betaine surfactant to improve foaming without inactivating the anti-bacterial and antiplaque activity of the quaternary ammonium compound, a humectant selected from the group consisting of polyethylene glycol, sorbitol, and mixtures thereof, a nonionic gelling agent, preferably hydroxyethylcellulose and a fluorine-containing compound capable of providing a fluoride ion, a small amount of glycerin to improve fluoride stability in polyethylene glycol humectant, in an aqueous vehicle containing a dental abrasive. A small amount of glycerin, as low as 1%, improves the long term fluoride stability of the dentifrice without adversely affecting the cosmetic stability thereof.

Antiplaque dentifrice with improved fluoride stability

A method and composition for improving hair body and manageability while not effecting a change in color, such method comprising applying to the hair an effective amount of an aqueous solution of from about 0.1% to about 10% by weight of an aromatic peracid oxidizing agent, particularly m-chloroperbenzoic acid and diperisophthalic acid, the aromatic peracid oxidizing agents providing maximum reaction with the fiber surface producing increased hair body and manageability with minimum diffusion into the interior of the hair so as to avoid effecting a change in color.
