Definitions
- the present invention relates to a chemical linkers that can be added to an organic chemical such as a perfume, insect repellent, antibacterial agent, and/or an allergen agent in order to reduce the rate of vaporization of the chemical additive from the surface to which it has been applied.
- an organic chemical such as a perfume, insect repellent, antibacterial agent, and/or an allergen agent
- the present invention also relates to a method for improving the retention time of an additive coated on a surface which comprises adding chemical linkers to an organic chemical such as a perfume, insect repellent, antibactehal agent, and/or an allergen agent in order to reduce the rate of vaporization of the organic chemical from the surface to which it has been applied.
- an organic chemical such as a perfume, insect repellent, antibactehal agent, and/or an allergen agent
- a major problem is how long a chemical additive such as a perfume, fabric softener, sunscreen agent, insect repellent, antibacterial agent and/or allergen agent will be effective on a surface on which the chemical has been deposited. For example, if the lasting effect of a perfume deposited on the human skin could be increased the necessity for repeat application of the perfume would be reduced. Alternatively, if the concentration of the perfume in a solution could be reduced while maintaining its effectiveness substantial cost savings could be achieved.
- the present invention relates to chemical linkers which can be added to the organic chemical whereby the chemical linker by chemical association links the organic chemical to the surface on which the organic chemical has been deposited thereby decreasing the rate of vaporization of the organic chemical.
- the requirement of the chemical linker is that when the chemical linker is added to a organic chemical that an exothermic interaction occurs between the chemical linker and the organic chemical which causes a reduction in the active vapor pressure of the organic chemical.
- the instant invention further relates to the use of the chemical linkers and the organic chemical in a surfactant based cleaning compositions.
- MNDA Methylneodecanamide
- This is necessary to deposit 10 micrograms of MNDA per cm2 to have one day efficacy. It is more than 500 molecular layers. To deliver this amount requires almost neat usage and is not compatible with consumers habits and practice. Unfortunately, one may not increase the MNDA concentration. It is desirable to increase the repellency duration without increase MNDA quantity.
- an organic chemical having a chemical group with a dipole moment of at least 1.5 selected from the group consisting of a chemical compound containing an amide linkage such as an insect repellents, antibacterial agents containing a carbon- halogen bond such as triclosan, allergen agents, fabric softener or sunscreen agent containing an ester group or enzymes containing acid groups and a chemical compound containing an aldehyde group or alcohol group such as those type of compounds present in perfumes and mixtures thereof; and
- a chemical linker which undergoes an exothermic reaction with the organic chemical
- the chemical linker can be a polyvinyl pyrrolidone polymer, an ethoxylated polyhydric alcohol, carboxylic acid having 4 to 6 carbon atoms and a polyethylene glycol having a molecular weight of 600 to 10,000, preferably 1 ,000 to 8,000 wherein the mole ratio of the organic chemical to the chemical linker is 4:1 to 1 :4.
- the present invention also relates to a process for improving the retention time of an organic chemical on a surface and to chemical compositions which comprise applying to a substrate a complex of by weight:

- compositions as prepared are aqueous liquid formulations and since no particular mixing is required to form the all purpose cleaning or microemulsion composition, the compositions are easily prepared simply by combining all the ingredients in a suitable vessel or container.
- the order of mixing the ingredients is not particularly important and generally the various ingredients can be added sequentially or all at once or in the form of aqueous solutions of each or all of the primary detergents and cosurfactants can be separately prepared and combined with each other and with the perfume.
- the magnesium salt, or other multivalent metal compound when present, can be added as an aqueous solution thereof or can be added directly. It is not necessary to use elevated temperatures in the formation step and room temperature is sufficient.

A 1.5 cm square notch was cut out of half of the resulting squares to provide the roaches access to the shelter. The tiles were washed with water before treatment. Each of six cut tiles (two with access openings) were treated with 0.62 ml of test product (Formula L) diluted 4:1. Similarly six control tiles were treated with 0.62 ml of an identical formulation which did not contain MNDA (Formula M) diluted 4:1.

Forty-eight hours prior to initiation of the assay, 50 male German cockroaches were allowed to acclimate to the pastic test cages (51 x 28 x 20 cm) with food and water available in the center, outside of the cups. A thin film of Teflon emulsion on the sides of the cages restricted the insects to the floor of the cage.
