  • Patent number: 5766611
    Abstract: The cosmetic product comprises soluble glass particles and liquid cosmetic base containing water. The soluble glass contains antibacterial metal ions selected from the group consisting of Ag.sup.+, Cu.sup.+, Cu.sup.2+ and Zn.sup.2+. The antibacterial ions contained are forming a solid solution with the components of soluble glass and elute along with the dissolution of the soluble glass skeletal network. The eluting rate of metallic ions is determined by the dissolving rate of the soluble glass and is not affected by the environmental concentration of alkaline metal ions, such as Na.sup.+.

  • Patent number: 5290544
    Abstract: A cosmetic product is provided which comprises particles of soluble glass having an average particle size of 20 .mu.m or less which contains silver ions. The soluble glass has a rate of elusion of the silver ions in water of from 0.00001-50 mg per hour per gram of glass when the soluble glass has a particle size of 420-600 .mu.m and the water has a temperature of 20.degree. C. The silver ions provide an anti-bacterial and anti-mold effect for a prolonged period without skin irritation, thus insuring a high degree of safety.
