  • Patent number: 5041281
    Abstract: A waterproof oil in water emulsion sunscreen composition is disclosed. The composition includes a film forming portion comprising between about 0.5 and about 20 weight percent of a copolymer of ethylene and vinyl acetate together with a second polymeric film forming agent which increases the substantivity of the film forming composition. This second polymeric film forming agent is present at between about 0.5 and about 10 weight percent. The sunscreen composition also includes between about 1 and about 30 percent sunscreen agent and between about 0.5 and about 10 percent of an emulsifier. In addition, the sunscreen composition includes between about 45 and about 90 percent water. A method of forming the water in oil sunscreen composition is also disclosed.

  • Patent number: 4414199
    Abstract: The specification discloses a fluoride toothpaste using a calcined kaolin abrasive which is at least 80% calcined and which has a particle-size distribution such that the majority of particles are between 1 and 10 microns in diameter, and not more than 35% of the particles are under one micron in diameter. The resulting toothpaste shows surprising efficacy in terms of fluoride availability, fluoride uptake on human enamel, enamel solubility reduction and polishing and stain removal.
