This invention provides a powder carbonate-based laundry detergent which can be utilized in cold water fabric laundering with a minimized remainder of undissolved detergent residue in the wash water. An essential aspect of the laundry detergent formulation is a content of a partially sulfated and neutralized blend of ethoxylated alcohol surfactant constituents. A preferred type of surfactant ingredient is a Neodol 23-3 derived type of blend which is 60-65 percent sulfated and neutralized.

Powder laundry detergent product with improved cold water residue properties

This invention provides a high carbonate-low phosphate powder laundry detergent formulation which can be utilized in cold water fabric laundering with a minimized remainder of undissolved detergent residue in the wash water. An essential aspect of the laundry detergent formulation is a content of a partially sulfated and neutralized blend of ethoxylated alcohol surfactant constituents. A preferred type of surfactant ingredient is a Neodol 23-3 derived type of blend which is 50-65 percent sulfated and neutralized.

High carbonate-low phosphate powder laundry detergent product with improved cold water residue properties

Multiparticulate controlled release preparations incorporating an alkalinizing potassium salt, preferably potassium bicarbonate, as an active ingredient, which are suitable for forming pharmaceutical dosage forms for oral administration. Such dosage forms are useful for potassium supplementation and for the treatment of degenerative bone or cardiovascular diseases, e.g., osteoporosis and hypertension.

Alkalinizing potassium salt controlled release preparations

A large size, small surface area, granular crystalline potassium bicarbonate product suitable for application as an active ingredient in pharmaceutical oral unit dosage forms useful for the treatment of various degenerative bone and cardiovascular diseases, particularly osteoporosis or hypertension, comprising potassium bicarbonate crystals having a mean particle size of at least 350 microns and a specific B.E.T. surface area less than 0.02 m.sup.2 /gram. A process for preparing such product is further provided, in which a solution of potassium bicarbonate is fed to a slurry of potassium bicarbonate crystals in a crystallizer and the temperatures and concentrations of the potassium bicarbonate in the feed solution and the crystallizer slurry are so regulated, and the residence time and degree of agitation in the crystallizer are so controlled, that the desired large size, small surface area potassium bicarbonate crystals are produced.

Large potassium bicarbonate crystals and process for the preparation

A stable, palatable and safe hydrogen peroxide releasing tooth powder composition containing sodium bicarbonate and sodium percarbonate in combination with flavoring agents, sweeteners, fluoridating agents, additional abrasives, surfactants and/or additional adjuvants.

Hydrogen peroxide-releasing tooth powder

A rigid, three-dimensional container comprising a top portion, a bottom portion and at least one side portion, said side portion having at least one opening covered with gas permeable membrane and means for sealing said opening until the container is ready for use by exposing material in the container to exterior gases such as the atmosphere while keeping the material in the container.
