Definitions
- the present invention relates to slow-release microcapsular insecticidal formulations comprising the insect repellent N,N' -diethyl-m-toluamide.
- the invention also relates to woven, non-woven, and knit substrates that are treated with the formulations of the invention.
- insect repellents are effective when applied to the skin as a spray or lotion, their effectiveness is known to decline with time. Furthermore, in order for an insect repellent to be effective, the insect repellent must be applied in a concentrated amount to a small area of the face, neck, and hands or on selected areas of a wearer's garment.
- the invention provides for a microcapsular insecticidal composition comprising a pyrethroid and a biological synergist capable of controlling insects for up to four (4) days.
- the invention provides for a tent fabric coated on the inside with a composition which renders it water repellent, flame retardant and insect repellent using permethrin as the insect repellent. Permethrin is protected against oxygen with a plasticizer. The outside of the tent is coated with a composition which renders it water repellent and flame retardant exclusive of the insect repellent.
- the insect- repellent composition has an effective life of more than six (6) months.
- the invention relates to compositions, devices and methods for controlling insect activity wherein an insect control agent is self-adhered to a rough-surfaced fiber and provides extended control of insect activity.
- the microencapsulated insect control agents disclosed in Barber are named as the preferred insecticide for use in Ronning' s invention.
- Ronning teaches that smooth-surfaced fibers do not act as good sites for adhesion of microencapsulated insect control agents.
- the invention relates to elongated flexible insect-repellent strips secured to or retained in cavities in various ar ⁇ ticles of apparel to repel insects from the person wearing such apparel.
- the invention relates to a coated fabric that is flame resistant and water repellent and includes a polyfunctional isocyanate as an adhesion promoter and binder to adhere the coating to the substrate in a flake proof manner.
- BDUs Uniforms used by the U.S. Military with amylopectin fabric wrinkle inhibitor and permethrin insect/arthropod repellent in combination.
- the invention relates to textiles impregnated with insect- repellent compositions including piperonyl butoxide and pyrethrin, wetting agent, thickener and an agent for preventing migration of the pyrethrin and piperonyl butoxide repellent into foods stored in contact with the textiles and for otherwise retaining the repellent in the textiles.
- This invention provides for fabric substrates treated with formulations which comprise an insect repellent such as for example N,N' -diethyl-m-toluamide (DEET) which is known to effectively control a variety of insects.
- DEET N,N' -diethyl-m-toluamide
- DEET is environmentally safe and leaves no harmful residues.
- DEET has been found to be stable at both reduced and elevated temperatures and under storage conditions.
- DEET is effective on biting flies, chiggers, deerflies, fleas, leeches, mosquitoes, and ticks.
- Several factors influence the efficacy of DEET as an insect repellent, such as, for example, extreme environmental conditions, the extent of absorption and elimination, the type of repellent formulation, and the avidity of the test species.
- the efficacy of DEET is reduced by increased perspiration rate and the duration of repellent activity is influenced by wash-off, abrasion from the treated surface and absorption. Water, from either rainfall or perspi
- the insect repellent is comprised in microcapsules with a diameter of from about 0.005 mm to about 1.800 mm.
- the insect repellent N,N' -diethyl-m-toluamide (DEET) can be together formulated and spray-dried to form mi- crocapsules in powder form.
- the formulation has novel properties in that the microencapsulated DEET can be time- released and the rate of release of the DEET can be con ⁇ trolled by varying the amounts of heavy alcohol or plas- ticizers used in the process.
- the DEET can time-release over a period of time spanning of from about 24 hours to about several months and is affected by the method of storage of the powder and exposure to light and air.
- time-release of DEET can be attributed to the entrapment of the DEET in the resulting structure of the capsule-forming compounds and the entrapping effect of the silicone elastomers.
- the time-release property of the DEET and the overall stability of the powder can be affected by further coating the microcapsule with for example a wax compound (bee wax, gelatin or polyethylene glycol and derivatives) for an intermediate coating or with for example a ceramic compound (clay, slip, china or ivory) for a harder coating or a protective layer.
- microcapsules and the powder include solubility in water and water-based compounds (such as for example lotions, cremes, latex paints, acrylic-based paints and sealers) as well as its solubility in oil, hydrocarbon solvents and the like. It is to be noted that before formulation, all compounds entering into the formulation including DEET were insoluble in water.
- insect-repellent formulations of the invention can be applied to a wide range of fabric substrates without being limited by the coarseness or smoothness of the fabric substrate.
- volatility is one of the functional attributes associated with insect repellency, and a high volatility lowers the long term effectiveness of the insect repellent
- this invention provides for an insect-repellent formulation which lowers the volatility of the insect repellent thus prolonging its effectiveness.
- insect-repellent formulations of the invention can be combined with a wide range of fabric treatment formulations.
- the resulting formulations can be applied to any suitable fabric substrate depending on the intended use of the fabric and the fabric treatment process such as, for example, cottons, knits, polyesters or blends, fiberglass, wovens or non-wovens and heat-sensitive substrates such as acetates and mode-acrylates and nylon.
- the formulations can be applied such that multiple layers of super thin laminates are produced and the insect repellent is thus slowly released at each laminate interface as it ruptures.
- the slow-release insect-repellent formulation of the invention can be prepared by first formulating the insect repellent N,N' -diethyl-m-toluamide with an oleophilic chemical such as a silicone compound such as for example elastomeric or monomeric silicone, and then by mechanical/ and or chemical entrapment of the resulting compound in a carbohydrate matrix, such as for example a starch compound including but not limited to corn starch, potato starch, technical starch, rice starch and any of the synthetic starches. Silicone, which is immiscible with water, is dissolved with the DEET which is also immiscible with water. The DEET-silicone solution is mixed into a starch solution with the resulting solution being miscible in water.
- an oleophilic chemical such as a silicone compound such as for example elastomeric or monomeric silicone
- the DEET molecule is entrapped in the lattice-like structure of the starch molecule which has the effect of lowering the vapor pressure of the insect repellent thus reducing its volatility.
- the DEET is slowly released from the lattice ⁇ like structure of the starch molecule with the net effect of the formation of a slow-release insect-repellent formulation.
- the slow-release insect-repellent formulation consists of from about 40% to about 75% starch, and of from about 10% to about 35% N,N'- diethyl-m-toluamide, and of from about 15% to about 25% silicone, preferably about 65% starch, about 15% N,N'- diethyl-m-toluamide and about 20% silicone on a dry weight basis.
- the slow-release insect- repellent microcapsules have a particle size of from about 0.005 mm to about 1.800 mm.
- the slow-release insect-repellent formulation of the invention is prepared by first dissolving starch in water at its boiling point.
- the starch solution is cooled to room temperature by further addition of water and the insecticide N,N' -diethyl-m-toluamide and silicone are slurried into the starch solution.
- the formulation is spray dried using conventional spray drying equipment such that the slurry produces a fine white powder comprising DEET of from about 8% to about 11% and with a moisture of from about 3% to about 8%, total solids of from about 10% to about 15% and little or no odor.
- the resultant slow-release insect-repellent formulations of the invention are a non-irritant to the skin or mucous membranes and are nontoxic.
- the slow-release insect-repellent formulation of the invention can be formulated for application on fabric substrate in high yields without affecting the functionality, esthetic appearance, hand or feel of the treated substrate and without leaving any residual odor.
- the slow-release insect-repellent formulation can be combined with a cationic softener and applied as a finishing rinse to a fabric substrate that has been already dyed.

- Fabric substrates after dyeing, pigment padding and printing, with the appropriate formulation which comprises the slow-release insect-repellent formulation of the invention, can be given a resin finish for hand, appearance and dimensional stability.
- the resin finish acts as a super thin laminate and provides the treated fabric with an insect-repellent finish and more particularly when the resin used is urea- formaldehyde by the cross-linking of the molecular structure of the cotton fiber to the cellulose fiber during resin curing conditions.
- the slow-release insect-repellent formulation is trapped during the reaction of the urea- formaldehyde with the cellulose molecule in the cotton fabric.
- substrate fabrics of 100% cotton and a 50/50 polyester/cotton blend can be treated with a resin finish comprising of from about 2% to about 5% (owf) of the slow-release insect-repellent formulation of the invention and of about 95% to about 98% (owf) of a resin finish formulation.
