Benefits of technology

The present invention provides an insect repellent and sun screen that is non-toxic for the skin of humans and animals, efficient for long periods of time, and does not irritate the skin. The composition includes a blend of natural oil extracts, vitamin F, phthalic acid, a volatile silicone, and a film forming polymer for water wash off resistance. The natural oils can be citronella oil, orange oil, eucalyptus oil, etc. The synthetic oils can be linalyl acetate, 1-limonene, etc. The sun screen includes a combination of natural oils, vitamin F, and a volatile silicone. The product can be applied to humans, pets, and livstock. The invention provides an effective and long-lasting insect repellent that also protects the skin from sun damage.

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.

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...
