Insect repellent with sun protection factor

Abstract

An insect repellent composition that includes a blend of either all natural oils or synthetic ingredients, a sunscreen vitamin F, volatile silicones to extend the effective repellent life of the spray and a film forming polymer to resist water wash off. The natural oils and extracts can include citronella and orange and the synthetics can include D-limonene and phtalic acid.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates generally to an insect repellent (either in a lotion, spray, cream, gel, salve, solid stick or ointment) for human beings and animals, and specifically, to a topical insect repellent that may include sun screen and that may be made with natural oils or botanical extracts, an additive to increase the time of repellent effectiveness and a film forming polymer to make the lotion more resistant to being washed off the skin with water, making the composition rain and sweat resistant once applied to the skin.[0003]2. Description of Related Art[0004]Insect repellents for human beings and domestic animals, especially pets, are well known in the art. Historically, original insect repellents often contain high levels of sometime toxic chemicals and were not medically good for skill contact in human beings or pets. Outdoor environments enjoyed by humans such as tropical climates, beaches or lakes include act...

AI Technical Summary

Benefits of technology

[0011]An insect repellent that is healthy for the skin that includes a composition having a blend of natural oil extracts to aid in warding off insects, vitamin F, phthalic acid, a volatile silicone to extend the skin time efficacy of the insect repellent and a film forming polymer for water wash off resistance making it rain and sweat resistant.

[0014]The volatile silicones in the composition are dimethicone or cyclomethicone. These are used to enhance or prolong the effective use of the insect warding off chemicals in the oils.

[0015]A film forming polymer is used to make the insect repellent lotion or spray adhere to the skin or fur to prevent being washed off by water, making the insect repellent rain and sweat resistant. This polymer can be PVM / MA co-polymer or butyl ester of PVM / MA co-polymer or isopropyl ester of PVM / MA co-polymer. The ethyl ester of PVM / MA co-polymer is preferred.

[0018]In the preferred embodiment, using natural oils, the materials are combined to provide for an insect repellent that includes vitamin F and a volatile silicone to extend the shelf life of the insect repellent chemicals or natural oils and a film forming polymer on the skin to prevent the insect repellent from being washed off the skin. With the use of the composition described herein, the product can be used for humans, pets and livestock. It is a long lasting, very effective insect repellent that may include sun screen to prevent skin damage from the sun.

[0020]It is therefore an object of the present invention to provide an insect repellent for application to the skin of a person or pet using a blend of natural or synthetic materials with the least toxicological risk and as a high efficacy over a long period of time without easily being removed from the skin of the user.

[0021]It is another object of this invention to provide an insect repellent and sun screen that is non-toxic for the skin of human beings and the skin and fur of animals including pets and livestock; that is efficient for long periods of time; and that prevents sun light damage to the skin.

Problems solved by technology

Historically, original insect repellents often contain high levels of sometime toxic chemicals and were not medically good for skill contact in human beings or pets.

One problem with insect sprays or lotions is lack of water / sweat tolerance.

Sweating, rain, and swimming tend to wash off, dissolve or evaporate the repellent from the skin of the user.

Another problem with insect repellents is that their effective insect repelling time period, once applied to the skin, is relatively short.

As stated above, many of the original insect repellents not only were toxic to insects but to human beings too.
