Description

【発明の詳細な説明】 徐放性昆虫忌避製剤及びその利用 関連出願のクロス−リファレンス 本願は1993年12月23日提出された名称「SLOW RELEASE INSECT-REPELLENT FORM ULATIONS AND USES」（徐放性昆虫忌避剤及び利用）の米国出願第08／173,416号 の一部継続出願である。 発明の分野 本発明は昆虫忌避製剤Ｎ，Ｎ′−ジエチル−ｍ−トルアミドを含んで成る徐放 性マイクロカプセル式殺虫製剤に関する。本発明は更に、本発明の製剤により処 理した布帛、不織布及びメリヤス基材に関する。 発明の背景 アパレル用途に適し、且つ長期の昆虫忌避性を供するアウトドア布帛について の永久的なニーズがある。多くの昆虫忌避剤はスプレー又はローションとして肌 に塗布したときに有用であるが、その効能は時間と共に下降する。更に、昆虫忌 避能が有効となるには、この昆虫忌避剤を顔、首及び手又は着用者の衣料の特定 の領域上の小さな領域に濃縮された量で塗布しなくてはならない。 昆虫忌避剤の効能はかかる忌避剤をアウトドア用途に適する布帛に直接塗布し たときに向上することが知られ、そして昆虫抑制剤の持続放出を供するための様 々な技術が提唱されている。 例えば、Barberらの米国特許第4,056,610号において、その発明は最大４日ま で昆虫を抑制することができるプレトロイド及び生物 学的相乗剤を含んで成るマイクロカプセル式殺虫剤を供している。 Samsonの米国特許第5,198,287号においては、その発明は昆虫忌避剤としてペ ルメトリンを利用する、撥水性、難燃性及び昆虫忌避性を供する組成物を内側に コーティングしたテント布帛を提供する。ペルメトリンは可塑剤によって酸素に 対して保護されている。テントの外側には、昆虫忌避性を除く、撥水性及び難燃 性を担う組成物をコーティングする。この昆虫忌避剤は６ケ月より長い有効寿命 を有する。 Ronningの米国特許第4,765,982号において、その発明は昆虫の活性を抑制する ための組成物、器具及び方法に関連し、それにおける昆虫抑制剤は粗い表面ファ イバーに対して粘着しており、そして昆虫の活性の長期抑制を担う。Barberにお いて開示されているマイクロ封入式昆虫抑制剤がRonnlngの発明における使用に とって好適な殺虫剤であると言われている。Ronningは、マイクロ封入式昆虫抑 制剤の付着部位にとって滑らかな表面のファイバーは良好な部位を担わないこと を教示している。 Petersonの米国特許において、その発明は様々なアパレル物品に固定した又は その穴の中に保持された、かかるアパレルを着用する者から昆虫を忌避せしめる ための長い柔軟式昆虫忌避ストリップに関する。 Mckinneyの米国特許第4,833,006号において、その発明は、難燃性及び撥水性 であり、且つ接着促進剤としての多価イソシアネート及びコーティングを基材に フレークプルーフ式に付着させるバインダーを含むコート布帛に関する。 McNallyの米国特許第5,089,298号において、その発明は、アミロペクチン布帛 しわ防止剤及びペルメトリン昆虫／節足動物忌避剤の組合せの、米国軍隊により 使用される戦闘用制服(BDUs)への含 浸に関する。 Yeadonらの米国特許第3,859,121号において、その発明は昆虫忌避剤の含浸さ れた織物に関連し、その剤はピペロニルブトキシド及びピレトリン、湿潤剤、増 粘剤、並びにその織布と接触状態で保存されている食品の中へのピレトリン及び ピペロニルブトキシドの混入を防ぐ、換言すれば織物の中に忌避剤を保持するた めの試薬を含む。 本発明は様々な昆虫を効果的に抑制することで知られている例えばＮ，Ｎ′− ジエチル−ｍ−トルアミド（DEET）の如くの昆虫忌避剤を含んで成る製剤で処理 した布帛基材を提供する。有効な昆虫忌避剤である他に、DEETは環境的に安全で あり、そして有害な残渣を残さない。DEETは低温及び高温の双方で、並びに貯蔵 条件下で安定であることが見い出された。DEETは、さしばえ、だにの幼虫、吸血 性あぶ類、のみ、ひる、蚊、だにに対して有効である。いくつかの要因、例えば 極端な環境条件、吸収及び排出の程度、忌避剤のタイプ、並びに試験抗体のどん 欲性がDEETの効能に影響を及ぼす。DEETの効能は高まった発汁率により低下し、 そして忌避活性の期間は洗い落ち、処理表面からの摩耗及び吸収により左右され る。雨又は発汁のいづれかに由来する水はDEETの効能を下げる。 発明の概要 本発明の第一の目的は、徐放性昆虫忌避製剤及びそれを製造する方法を提供す ることにあり、その製剤は昆虫忌避剤を炭水化物マトリックスの中に、その昆虫 忌避剤がそのマトリックスから徐放されるように封入されて含んで成る。この昆 虫忌避剤は約0.005mm〜約1.800mmの直径を有するマイクロカプセルの中に含まれ ている。 本発明の更なる目的は布帛、不織物及びメリヤス基材を処理する のに適する徐放性昆虫忌避製剤及びその製造方法を提供することにある。 本発明の更なる別の目的は、本発明の昆虫忌避製剤により布帛基材を処理する 方法を提供することにある。 本発明の更なる別の目的は、本発明の昆虫忌避製剤により昆虫を忌避する方法 を提供することにある。 本発明の別の目的は、12ケ月まで昆虫忌避能を有し、そして消費者のアパレル の安定性に匹敵する安定性を有する本発明の製剤で処理した布帛基材の提供にあ る。 本発明の別の目的は本発明の布帛基材により製造した衣料の提供にある。 その他の目的は以降において明らかとなるであろう。 好適な態様の詳細な説明 親油性（oleophilic）シリコーン化合物、重質アルコール（例えばポリビニル アルコール、エアボール（airvol）、ポリビニルアセテート、液化合成ゴム又は アクリル系コポリマー）及び昆虫忌避剤Ｎ，Ｎ′−ジエチル−ｍ−トルアミド（ DEET）は一緒に配合してスプレー乾燥せしめて粉末状のマイクロカプセルを形成 せしめることができる。この製剤は、マイクロ封入DEETが徐放式であり、そして DEETの放出速度が前記工程において用いた重質アルコール又は可塑剤の量を変え ることにより調節できる点における新規の特性を有する。DEETは約24時間からお よそ数ケ月に至る時間にわたって徐放性であることができ、そして粉末の貯蔵法 並びに光及び空気に対する曝露により影響される。DEETの徐放性はカプセル形成 化合物の結果としての構造の中でのDEETの封入及びシリコーンエラストマーの封 入効果に依存しうるものと信じられている。DEETの徐放特性及び粉 末の全体的な安定性は、例えばマイクロカプセルを中間コーティング用のワック ス化合物（ビーワックス、ゼラチン又はポリエチレングルコール及び誘導体）に より、又は例えばより硬いコーティングもしくは保護層用のセラミック化合物（ 粘土、スリップ、チャイナもしくはアイボリー）により更にコーティングするこ とにより影響されうる。 マイクロカプセル及び粉末のその他の新規の特性には、水及び水性ベース化合 物（例えばローション、クリーム、ラテックスペイント、アクリル系ペイント及 びシール材の如く）中での溶解性、並びに油、炭化水素溶媒中の溶解度が含まれ る。配合の前、製剤の中に入れるDEETを含む全ての化合物は水に不溶性であるこ とに注目すべきである。 本発明の昆虫忌避製剤は、布帛基材の粗さ又は滑らかさにより制約されること なく多種多様な布帛基材に適用できる。揮発性は昆虫忌避能に関与する機能属性 の一つであり、そして高い揮発性は昆虫忌避の長期効能を下げるため、本発明は 昆虫忌避剤の揮発性を下げ、それ故その効能を長期化する昆虫忌避製剤を提供す る。 更に、本発明の昆虫忌避剤は多種多様な布帛処理製剤と組合せてよい。得られ る製剤は布帛の意図する用途及び布帛処理工程に依存して任意の適当な布帛基材 、例えば綿、メリヤス、ポリエステルもしくはブレンド、ファイバーガラス、織 布もしくは不織布、並びに感熱基材、例えばアセテート及びモード−アクリレー ト及びナイロンに適用できうる。昆虫忌避揮発性を下げるため及び昆虫忌避活性 の損失を調節するため、この製剤は、超薄ラミネートの多重層が出き上がるよう に適用してよく、そしてこれにより昆虫忌避剤は各ラミネート界面においてそれ が破れる際に徐放されるようになる。 本発明の徐放性昆虫忌避製剤は、まず昆虫忌避剤Ｎ，Ｎ′−ジエ チル−ｍ−トルアミドを親油性化学品、例えばシリコーン化合物、例えばエラス トマー又はモノマーシリコーンと配合し、次いで得られる化合物を炭水化物マト リックス、例えばスターチ化合物、例えば限定することなくコーンスターチ、ポ テトスターチ、テクニカルスターチ、ライススターチ及び任意の合成スターチの 中に機械及び／又は化学封入することにより調製できる。水と非混和性であるシ リコーンを、これも水に非混和性であるDEETにより溶解させる。DEET−シリコー ン溶液をスターチ溶液の中に混合し、得られる溶液は水に混和性である。DEET分 子はスターチ分子のはしご状構造の中に封入され、それは昆虫忌避剤の蒸気圧を 下げる効果を有し、それ故揮発性を低める。このDEETは、徐放性昆虫忌避剤の形 成の正味の効果をもってスターチ分子のはしご状構造から徐放される。 好適な態様において、この徐放性昆虫忌避製剤は、重量ベースで、約40％〜約 75％のスターチ、及び約10％〜約35％のＮ，Ｎ′−ジエチル−ｍ−トルアミド、 及び約15％〜約25％のシリコーンより成り、好ましくは約65％のスターチ、約15 ％のＮ，Ｎ′−ジエチル−ｍ−トルアミド及び約20％のシリコーンより成る。ス プレー乾燥を経て、徐放性昆虫忌避マイクロカプセルは約0.005mm〜約1.800mmの 粒子サイズを有する。 本発明の徐放性昆虫忌避製剤はまずスターチを水の中にその沸点において溶解 させることにより調製する。スターチ溶液を水の更なる添加により室温にまでさ まし、そして殺虫剤Ｎ，Ｎ′−ジエチル−ｍ−トルアミド及びシリコーンをスタ ーチ溶液の中へとスラリー化する。スラリー化の後、この製剤を慣用のスプレー 乾燥装置を利用してスプレー乾燥し、これによりこのスラリーは約８％〜約11％ のDEET及び約３％〜約８％の水分、約10％〜約15％の総固形分、及びあるにして も若干の香料を含んで成る微細な白色粉末をもたらす 。 得られる本発明の徐放性昆虫忌避剤は肌又は粘膜に対して非刺激性であり、そ

Cross-Reference of Sustained Release Insect Repellent Formulation and Application Related thereto The present application is filed on Dec. 23, 1993 under the name "SLOW RELEASE INSECT-REPELLENT FORM ULATIONS AND USES". Repellent and Utilization) is a continuation-in-part application of US Application No. 08 / 173,416. FIELD OF THE INVENTION The present invention relates to a sustained release microcapsule insecticide formulation comprising an insect repellent formulation N, N'-diethyl-m-toluamide. The invention further relates to fabrics, nonwovens and knitted substrates treated with the formulations of the invention. BACKGROUND OF THE INVENTION There is a permanent need for outdoor fabrics that are suitable for apparel applications and provide long-term insect repellency. Many insect repellents are useful when applied to the skin as a spray or lotion, but their efficacy declines over time. In addition, for insect repellent to be effective, the insect repellent must be applied in concentrated amounts to small areas on the face, neck and hands or specific areas of the wearer's clothing. It is known that the efficacy of insect repellents is enhanced when such repellents are applied directly to fabrics suitable for outdoor use, and various techniques have been proposed to provide sustained release of insect repellents. For example, in US Pat. No. 4,056,610 to Barber et al., The invention provides a microcapsule insecticide comprising a prethroid and a biological synergist capable of controlling insects for up to 4 days. In Samson, US Pat. No. 5,198,287, the invention provides a tent fabric coated on the inside with a composition that provides water repellency, flame retardancy and insect repellent utilizing permethrin as an insect repellent. Permethrin is protected against oxygen by a plasticizer. The outside of the tent is coated with a composition that is responsible for water repellency and flame retardancy, excluding insect repellency. This insect repellent has a useful life of more than 6 months. In Ronning U.S. Pat.No. 4,765,982, the invention relates to compositions, devices and methods for inhibiting insect activity, wherein the insect control agent adheres to a rough surface fiber and Responsible for long-term suppression of activity. The microencapsulated insect control agent disclosed in Barber is said to be a suitable insecticide for use in the Ronnlng invention. Ronning teaches that fibers with a smooth surface do not carry good sites for attachment sites of microencapsulated insect control agents. In Peterson's U.S. patent, the invention relates to a long flexible insect repellent strip secured to various apparel articles or retained in its holes to repel insects from the wearer of such apparel. In Mckinney, U.S. Pat. No. 4,833,006, the invention relates to a coated fabric that is flame retardant and water repellent and that includes a polyisocyanate as an adhesion promoter and a binder that flake proofly attaches the coating to a substrate. In McNally, US Pat. No. 5,089,298, the invention relates to impregnation of combat uniforms (BDUs) used by the US military with a combination of an amylopectin fabric anti-wrinkle agent and a permethrin insect / arthropod repellent. In U.S. Pat.No. 3,859,121 to Yeadon et al., The invention relates to a fabric impregnated with an insect repellent, which is stored in contact with piperonyl butoxide and pyrethrin, a humectant, a thickener, and the fabric. Reagents are included to prevent the incorporation of pyrethrins and piperonyl butoxide into the food in which they are present, in other words to keep the repellent in the fabric. The present invention provides a fabric substrate treated with a formulation comprising an insect repellent such as N, N'-diethyl-m-toluamide (DEET) known to effectively control various insects. provide. Besides being an effective insect repellent, DEET is environmentally safe and leaves no harmful residues. DEET was found to be stable at both low and high temperatures and under storage conditions. DEET is effective against larvae of larvae, larvae of larvae, blood-sucking oilflies, chisel, moats, mosquitoes and larvae. Several factors influence the efficacy of DEET, including extreme environmental conditions, degree of absorption and excretion, type of repellent, and greed of the test antibody. The efficacy of DEET is diminished by the increased rate of exudation, and the duration of repellent activity is washed off and depends on abrasion and absorption from the treated surface. Water derived from either rain or dripping reduces the effectiveness of DEET. SUMMARY OF THE INVENTION A first object of the present invention is to provide a sustained release insect repellent formulation and a method for producing the same, which formulation comprises an insect repellent in a carbohydrate matrix, the insect repellent comprising: It is included so as to be slowly released from the matrix. The insect repellent is contained in microcapsules having a diameter of about 0.005 mm to about 1.800 mm. It is a further object of the present invention to provide a sustained release insect repellent formulation suitable for treating fabrics, non-wovens and knitted substrates and a method of making the same. Yet another object of the present invention is to provide a method of treating a fabric substrate with the insect repellent formulation of the present invention. Still another object of the present invention is to provide a method for repelling insects by the insect repellent preparation of the present invention. Another object of the present invention is to provide a fabric substrate treated with the formulation of the present invention which has insect repellent ability for up to 12 months and has stability comparable to that of consumer apparel. Another object of the invention is to provide a garment made from the fabric substrate of the invention. Other purposes will become apparent later. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Lipophilic silicone compounds, heavy alcohols (eg polyvinyl alcohol, airvol, polyvinyl acetate, liquefied synthetic rubber or acrylic copolymers) and insect repellent N, N'-diethyl. -M-Toluamide (DEET) can be blended together and spray dried to form powdered microcapsules. This formulation has novel properties in that the microencapsulated DEET is a sustained release and the release rate of DEET can be controlled by varying the amount of heavy alcohol or plasticizer used in the process. DEET can be sustained-release over a period of about 24 hours up to several months and is affected by powder storage and exposure to light and air. It is believed that the sustained release properties of DEET may depend on the encapsulation effect of DEET and the encapsulation effect of the silicone elastomer in the resulting structure of the encapsulating compound. The sustained release properties of DEET and the overall stability of the powder can be determined, for example, by wax compounds (beeswax, gelatin or polyethylene glycols and derivatives) for intermediate coating of microcapsules, or for example ceramics for harder coatings or protective layers. It can be influenced by further coating with compounds (clay, slip, china or ivory). Other novel properties of microcapsules and powders include their solubility in water and aqueous based compounds (such as lotions, creams, latex paints, acrylic paints and sealants), and in oils, hydrocarbon solvents. Includes solubility. It should be noted that all compounds, including DEET, included in the formulation prior to formulation are insoluble in water. The insect repellent formulation of the present invention can be applied to a wide variety of fabric substrates without being restricted by the roughness or smoothness of the fabric substrate. Since volatility is one of the functional attributes involved in insect repellent ability, and high volatility reduces long-term efficacy of insect repellent, the present invention reduces the volatility of insect repellent and therefore prolongs its efficacy. An insect repellent preparation is provided. Further, the insect repellents of the present invention may be combined with a wide variety of fabric treatment formulations. The resulting formulation may be any suitable fabric substrate, such as cotton, knit, polyester or blend, fiberglass, woven or non-woven fabric, and heat sensitive substrates such as acetate and the like, depending on the intended use of the fabric and the fabric treatment process. Applicable to mode-acrylate and nylon. In order to reduce insect repellent volatility and to control loss of insect repellent activity, this formulation may be applied so that multiple layers of ultra-thin laminates emerge, thereby allowing insect repellents at each laminate interface. When it breaks, it will be released gradually. The sustained-release insect repellent formulation of the present invention comprises first blending the insect repellent N, N'-diethyl-m-toluamide with a lipophilic chemical, such as a silicone compound such as an elastomer or a monomer silicone, and then combining the resulting compound with a carbohydrate. It can be prepared by mechanical and / or chemical encapsulation in a matrix such as a starch compound such as, but not limited to, corn starch, potato starch, technical starch, rice starch and any synthetic starch. The silicone, which is immiscible with water, is dissolved with DEET, which is also immiscible with water. The DEET-silicone solution is mixed into the starch solution and the resulting solution is miscible in water. The DEET molecule is encapsulated within the ladder-like structure of the starch molecule, which has the effect of lowering the vapor pressure of the insect repellent and thus reducing its volatility. This DEET is released from the ladder-like structure of the starch molecule with the net effect of forming a sustained release insect repellent. In a preferred embodiment, the sustained release insect repellent formulation comprises, on a weight basis, about 40% to about 75% starch, and about 10% to about 35% N, N'-diethyl-m-toluamide, and about It comprises 15% to about 25% silicone, preferably about 65% starch, about 15% N, N'-diethyl-m-toluamide and about 20% silicone. After spray drying, the sustained release insect repellent microcapsules have a particle size of about 0.005 mm to about 1.800 mm. The sustained release insect repellent formulation of the present invention is prepared by first dissolving starch in water at its boiling point. The starch solution is allowed to reach room temperature by further addition of water and the insecticide N, N'-diethyl-m-toluamide and silicone are slurried into the starch solution. After slurrying, the formulation is spray dried using a conventional spray dryer, whereby the slurry has a DEET content of about 8% to about 11% and a water content of about 3% to about 8%, about 10% to about 10%. This gives a fine white powder which comprises about 15% total solids and, if any, some perfume. The resulting sustained release insect repellent of the present invention is non-irritating to skin or mucous membranes and non-toxic. By explaining the following aspects, the sustained-release insect repellent formulation of the present invention can be used in a large amount of fabric without impairing the function, aesthetic appearance, touch of the treated substrate and leaving any residual odor. It can be compounded for application on a substrate. In a preferred embodiment, the sustained release insect repellent formulation can be combined with a cationic softener and applied as a final rinse to an already dyed fabric substrate. The sustained release insect repellent formulation comprises about 2% to about 10% of the sustained release insect repellent and about 2% to about 6% (owf) of the weight of the fabric. It may be combined into a formulation comprising a cationic softening agent. The formulation may be released under mild acidic conditions, for example with acetic acid having a pH of about 5.50 to about 6.60 onto the fabric substrate, the sustained release insect repellent attached to the cationic site in the dye, The cationic softener then adheres to the fabric substrate. In another preferred embodiment, the sustained release insect repellent formulation composition comprises about 90% to about 98% (owf) pad formulation and about 2% to about 10% (owf) sustained release insect repellent. It can be combined into a formulation comprising. In another preferred embodiment, the sustained release insect repellent formulation comprises about 90% to about 98% (owf) pigment printing paste formulation and about 2% to about 10% (owf) sustained release insect repellent. May be combined in a formulation consisting of The sustained release insect repellent crosslinks with the pigment binder during pigment dyeing and during printing for incorporation onto the cellulose substrate of the fabric substrate. In another preferred embodiment, the sustained release insect repellent formulation comprises about 90% to about 98% (owf) water repellent and about 2% to about 10% (owf) sustained release insect repellent. May be combined in different formulations. In another preferred embodiment, the sustained release insect repellent formulation may be utilized in the final rinse formulation. Fabric substrates that have undergone dyeing, pigment padding, and printing, with suitable formulations comprising the sustained release insect repellent formulations of the present invention, may impart a resin finish for feel, appearance and dimensional stability. In this particular embodiment, the resin finish is responsible for the ultra-thin laminate and provides a treated fabric having an insect repellent finish (and, more specifically, when the resin used is urea-formaldehyde, cellulose during resin cure conditions). Through the cross-linking of the molecular structure of the cotton fiber to the fiber). Sustained-release insect repellent formulations are entrapped during the reaction of urea-formaldehyde with cellulose molecules in cotton fabrics. In a preferred embodiment, 100% cotton and 50/50 polyester / cotton blend base fabrics are provided with from about 2% to about 5% (owf) of the sustained release insect repellent formulation of the present invention and from about 95% to about 98%. % (Owf) of resin finish formulation may be included in the resin finish.

Example VII About 2% to about 10% (w / w) of the sustained release insect repellent formulation of Example I may be combined with about 2% ink dispersant and about 85% extender. The fabric was treated by thermal transfer printing, that is, by vaporizing the dye from the paper to the fabric at the dye sublimation temperature. Example VIII About 2% to about 10% (w / w) of the sustained release insect repellent formulation of Example I can be combined with about 100% extender. The fabric was treated by thermal transfer printing, that is, by vaporizing the dye from the paper to the fabric at the dye sublimation temperature. Field Tests The sustained release insect repellents of the present invention have been found to be responsible for complete wearer protection under all types of weather and attack conditions. Furthermore, it was found that the insect repellent efficacy of the fabric substrate treatment extends from about several hours to about 12 months. To test the stability of the fabric treatment, garments were made from the treated fabric. Fabric substrates washed with 10 to 50 washes continued to exhibit insect repellent properties. The industry standard wash number for apparel is 3, 5 or 10 for consumer apparel, and 50 for military or certain special requirements, such as flame retardant. Should be noted. To test the efficacy of the treatment, laboratory sized knit and woven samples were treated with the above formulation. The first batch of samples was tested for direct insect repellency utilizing Hariari and fruit flies as test insects. Hariari and fruit flies were directly repelled by the fabric samples for several hours. A second batch of fabric sample was tested by a wearer wearing a shirt consisting of this fabric sample. Mosquitoes and blow flies were repelled for at least 11 hours during the fishing trip. Production testing was started with four fabric substrates, knitted and woven cotton, poly / cotton and poly / nylon. The fabrics were dyed with a sustained release insect repellent applied during dyeing or resin finishing as one type of fabric group. Another group of knitted and woven fabrics was padding dyed, printed and resin finished, and the sustained release insect repellent was applied in the dyeing, printing and resin finishing process. Garments such as shirts, hats and the like were made from this treated fabric substrate. The garment was tested under the conditions encountered during outdoor activities. Clothing has been found to repel insects under outdoor conditions during activities such as hiking, hunting and fishing under conditions of day and night wear on the coast, mountainous areas and mountains. Treated garments were compared to their untreated counterparts under the same conditions. In one particular field test, clothing was tested for mosquitoes. Mosquitoes landed on bare skin and immediately stabbed. On the other hand, when the mosquitoes landed on the treated fabrics somewhere on the garment, they stayed only about 4 to about 6 seconds before taking off. The invention and its numerous advantages can be understood from the above description, and it is apparent that various modifications and changes can be made without departing from the scope of the invention. For example, the sustained release repellents of the present invention can include various insect control agents such as permethrin and the more common alkylamides and alkylneodesamides. In addition, the controlled release insect repellents can be used in a wide variety of fabric substrates including, but not limited to, woven blends, woven and non-woven fabrics, knitted fabrics, fibers, leather and synthetic leather improvements, tethered fabrics, wood and wood. Applicable to dielectrics, plastics and laminates, cables, sheet materials, films, fiberglass and plexiglass. The sustained release insect repellent may comprise moth-preventing agents, packaging materials and paints. In addition, hard cover capsules may provide long term repellency when such capsules are used in commercial finishes, such as in the production of caulks, paint sealers, wall and floor coverings and the like. Furthermore, the formulations of the present invention may have wide application in situations requiring low concentrations of DEET. For example, the sustained release insect repellent may include a fragrance or perfume or pheromone, or any other formulation that may facilitate use in sports, farming or hunting situations. On the other hand, higher concentrations of repellent up to about 20% to about 25% solids may be used in the caulking compound. The present invention may be embodied in other specific forms without departing from the scope of the invention. Therefore, reference should be made to the claims, not the above specification, as to the scope of the invention.
