Abstract
An air freshener gel consisting essentially of a novel gelling agent and an aqueous medium containing a volatile air freshener component. The novel gelling agent comprises carrageenan, locut bean gum, and a water soluble ammonium salt having a pH greater than about 5.0. The carrageenan contains at least 40% by weight of the carrageenan, kappa carrageenan. The improved air freshener gels exhibit practically no syneresis, improved water gel strength, and water viscosity.
Claims16
In an air freshener gel consisting essentially of about 1.5 to 4% of a gelling agent, and about 98.5 to 96% of an aqueous medium containing a volatile air freshener component;
- the improvement which comprises a gelling agent comprising:
- a. from about 0.6 to about 2% of a carrageenan of which at least 40% by weight is the kappa fraction,
- b. from about 0.2 to about 1.0% of locust bean gum;
- and
- c. from about 0.05 to about 1.0% of a water soluble ammonium salt having a pH greater than about 5.0 selected from the group consisting of ammonium chloride, ammonium sulfate, ammonium acetate, ammonium phosphate (dibasic) and mixtures thereof,
- wherein said percent is percent by weight of said air freshener gel.
In an air freshener gel consisting of about 2.5 to 3.0% of a gelling agent and about 97.5 to 97% of an aqueous medium containing a volatile air freshener component;
- the improvement which comprises a gelling agent comprising:
- from about 1.0 to about 1.8% of a carrageenan containing at least 40% by weight of the kappa fraction,
- b. from about 0.4 to about 0.8% of locust bean gum;
- and
- c. from about 0.5 to about 1.0% of a water soluble ammonium salt selected from the group consisting of ammonium chloride, ammonium sulfate, ammonium acetate, ammonium phosphate (dibasic), and mixtures thereof,
- wherein said percent is percent by weight of said freshener gel.
