  • Patent number: 6080711
    Abstract: A powdered laundry detergent is provided with (a) a powder laundry detergent base that includes an inorganic carrier and a surfactant and (b) post-added acidulant and discrete whitening agent particles to provide a detergent having improved cool water solubility with bulk color deterioration caused by whitening agents being minimized. The detergent includes from about 5% to about 80% of an inorganic carrier, from about 1% to about 90% of a detergent surfactant, from about 0.1% up to about 15% of an acidulant and from about 0.1% up to about 30% of the discrete whitening agent particles. The acidulant is selected from the group of acids that in an acid form are soluble in water in an amount not greater than about 8%, preferably not greater than about 0.7% by weight at 25.degree. C. and in a salt form are soluble in water at least in an amount of about 15% by weight at 25.degree. C. The whitening agent particles include a whitening agent and a surfactant.

  • Patent number: 5998351
    Abstract: A powdered laundry detergent is provided with discrete whitening agent particles that do not adversely affect the bulk appearance of the detergent during storage. The detergent includes from about 5% to about 80% of an inorganic carrier, from about 1% to about 90% of a detergent surfactant, and from 0.1% up to about 30% of the discrete whitening agent particles. The whitening agent particles include a whitening agent and a surfactant. The surfactant for the whitening agent particle includes those anionics, nonionics, zwitterionics, ampholytics, cationics, and mixtures thereof that are solids in a temperature range of from about 32.degree. F. (0.degree. C.) to about 180.degree. F. (82.degree. C.). The whitening agent particles, in a more desirably form, include a whitener and water. The particles are formed by extruding a homogenous mass into discrete particles. The homogenous mass includes either a whitening agent, a surfactant, and optionally a plasticizer or a whitening agent and water.

  • Patent number: 5714456
    Abstract: A process for preparing discrete whitening agent particles that includes the steps of providing a whitening agent, admixing a surfactant that is a solid in a temperature range of from about 32.degree. F. (0.degree. C.) to about 180.degree. F. (82.degree. C.) with the whitening agent to form a substantially homogenous mass, and forming the mixture into discrete particles.

  • Patent number: 5709918
    Abstract: An information indicator used for a tire production control label or the like is provided with a film-type substrate formed of a heat-resistant resin. An information indicating surface onto which a recognizable indication indicating specified information is printed is formed on one surface of the substrate, and a pressure sensitive adhesive layer is formed via a primer layer on the other surface of the substrate. The information indicating surface is formed so as to have a surface roughness whose arithmetical mean deviation of the profile determined in JIS B 0801 lies between 0.5 and 5 .mu.m, and an indication such as a bar code, characters, figures, symbols or drawings is attached to the information indicating surface. With the information indicator formed in this way, the indication does not become blurred or erased even under the high temperatures and high pressures during vulcanization.
