Abstract: Lubricants and drilling fluid systems comprising lubricants which form a coherent lubricating film on metal equipment, thereby prolonging equipment life even under a wide variety of conditions, including high temperature and/or high pressure conditions.

Abstract: An oral composition, such as a toothpaste, includes an anti-tartar proportion of a polyphosphate anti-tartar agent (preferably with synthetic anionic polymeric polycarboxylate or equivalent, and fluoride) and a desensitizing proportion of a tooth pain inhibiting potassium salt which passes through exposed dentin tubules to tooth nerves or neurons, which salt can be potassium nitrate, potassium citrate or potassium oxalate, so that it helps to prevent tartar from forming on the teeth and also lessens any pain experienced by persons contacting their sensitive teeth with the oral composition. Preferably the oral composition is a desensitizing anti-tartar toothpaste or gel which, when the teeth are brushed with it, aids in removal of at least some tartar and prevents its reappearance, and at the same time diminishes any tooth pain that the brusher would otherwise experience due to such brushing.

Abstract: An aqueous storage-stable mouthwash composition, optionally in the form of a gel and optionally containing special wintergreen or cinnamon flavor mixtures, comprising about 0.5 to about 5% by weight of hydrogen peroxide and about 0.01 to about 2% by weight of a compound providing fluoride or fluoride-containing ions in the composition.

Abstract: Functional agglomerated speckles, for incorporation in dentifrices, include agglomerates of a water insoluble powdered functional material and water insoluble, ethanol soluble ethyl cellulose. Such speckles satisfactorily maintain their integrity and identity during processing of the dentifrice after addition of the speckles to the main dentifrice body but on storage, after packaging of the dentifrice in dispensing tubes, soften sufficiently so as to become essentially impalpable to one utilizing the dentifrice in brushing his teeth. Despite such softening the speckles continue to maintain their identity as speckles in the dentifrice. The speckles are especially useful in translucent or transparent gel dentifrices which contain components, such as flavoring and surface active agents, which may controllably soften the speckles on storage.

Abstract: An aqueous oral preparation is provided which contains a peroxygen compound and a flavor which is stable in such system. The peroxygen compound is preferably hydrogen peroxide. The preparation may be in the form of a mouthrinse, a paste or a gel. Many optional ingredients may be included such as ethanol, polyhydric alcohols, non-ionic surfactants, fluorides, color, preservative, sweetener, and the like. A preferred rinse includes ethanol, sorbitol, a Pluronic surfactant, a Tween surfactant, sodium saccharin, and color. A typically preferred gel is similar to the rinse but contains about 20 wt. % of a thickener.
