摘要:
Solid core particles encapsulated in a single coat of paraffin wax, the wax having a melting point of about 40.degree. to about 50.degree. C. and a solids content of from 100 to about 35% at 40.degree. C. and from 0 to about 15% at 50.degree. C. The paraffin coat may comprise 20 to 90% by weight of the particle and may be from 100 to 1,500 microns thick. The coat prolongs the time in which particles encapsulated therewith may remain active in aqueous environments.The encapsulated particle is made by spraying molten wax onto the particles in a fluidized bed. Liquid or powder cleaning compositions, particularly automatic dishwashing liquid detergents, may incorporate 0.01 to 20% by weight of the composition of the coated wax-encapsulated particles.

摘要:
Antimicrobial compositions having a rapid and persistent antiviral effectiveness against influenza viruses, including avian flu viruses, are disclosed. The antimicrobial compositions contain (a) a disinfecting alcohol, (b) an organic acid, and (c) water, wherein the composition has a pH of about 5 or less and the nonvolatile components of the composition are capable of forming a barrier film or layer on a treated surface.

Antimicrobial compositions having a rapid effectiveness against noroviruses and against bacteria are disclosed. The antimicrobial compositions contain a disinfecting alcohol, an organic acid, and water, wherein the composition has a pH of about 5 or less and the nonvolatile components of the composition are capable of forming a barrier film or layer on a treated surface.
摘要:
A dual component whitening dentifrice composition is disclosed which comprises a first dentifrice component containing a peroxide compound such as urea peroxide and a second dentifrice component containing an abrasive such as alumina or silica which is incompatible with the peroxide, the first and second dentifrice components being maintained separate from the other until dispensed and combined for application to teeth requiring whitening.
摘要:
A stable fragrance-containing gel is provided which is capable of being mixed with a fragrance-free base composition comprised of a homogeneous aqueous structured liquid detergent composition to form a pourable fragrance-containing homogeneous aqueous structured detergent composition. The resulting structured detergent composition provides enhanced deposition and longevity of fragrance upon fabrics laundered with such fragrance-containing detergent composition as compared to laundering with an otherwise identical composition containing the same level of fragrance but in the absence of said fragrance-containing gel, said fragrance-containing gel comprising: (a) a polyacrylic acid polymer having an average particle size below about 1 mm; (b) water in an amount sufficient to form a gel with said polymer; (c) a fragrance dispersed within said gel; and (d) a nonionic surfactant in an amount sufficient to emulsify said fragrance and enhance its dispersion within said gel to provide a stable fragrance-containing gel.
