摘要:
A process for the preparation of substantially water-insoluble, particulate sodium carboxymethyl cellulose, suitable for use as an absorbent in tampons and other catamenial devices, or the like. The process involves treating solid, water-soluble sodium carboxymethyl cellulose having a degree of substitution of at least 0.4 with hydrogen chloride gas and heating the carboxymethyl cellulose, either after the hydrogen chloride treatment or concurrently therewith, to produce a cross-linked, insoluble, partially acid form carboxymethyl cellulose suitable for absorbent applications.

摘要:
Improved padded brassieres in which the padding layer within the cup structure includes a batting of fibers formed together into a cohesive fibrous web, the batting having a plurality of areas devoid of fibers to provide a patterned openwork structure. The open areas are typically in the range of approximately 1/32 to 1/4 of an inch in length and width, arranged in rows of predetermined linear alignment to provide an aesthetic arrangement having porosity, strength, integrity and excellent drapable characteristics.
摘要:
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.

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.
摘要:
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.
