  • NON-AQUEOUS ORAL CARE COMPOSITIONS
    Publication number: 20140234383
    Abstract: The invention provides a non-aqueous oral care composition with a liquid continuous phase comprising a thickening agent, a humectant, and a crystalline structuring agent, characterised in that the composition further comprises abrasive amorphous silica particles which are capable of acting as a booster to the cleaning ability of the composition and which have a weight mean particle size (d50) ranging from 3 to 15 microns. Preferred components are carboxyvinyl polymers as thickening agent, glycerin as humectant and solid polyethylene glycols such as polyethylene glycol 3000 as structuring agent. The composition may further comprise a liquid polyethylene glycol. The composition has improved appearance (in particular shine or glossiness) and improved squeezability, i.e. good rheology, even at high temperatures (such as 40° C.).
