Local Anesthetic Api 99% Benzocaine CAS 94-09-7 Ethyl 4-Aminobenzoate

Benzocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body.
Benzocaine topical is used to reduce pain or discomfort caused by minor skin irritations, sore throat, sunburn, teething pain, vaginal or rectal irritation, ingrown toenails, hemorrhoids, and many other sources of minor pain on a surface of the body. Benzocaine is also used to numb the skin or surfaces inside the mouth, nose, throat, vagina, or rectum to lessen the pain of inserting a medical instrument such as a tube or speculum.
Benzocaine is used as a key ingredient in numerous pharmaceuticals:

Some glycerol-based ear medications for use in removing excess wax as well as relieving ear conditions such as otitis media and swimmers ear.
Some previous diet products such as Ayds.
Some condoms designed to prevent premature ejaculation. Benzocaine largely inhibits sensitivity on the penis, and can allow for an erection to be maintained longer (in a continuous act) by delaying ejaculation. Conversely, an erection will also fade faster if stimulus is interrupted.
Benzocaine mucoadhesive patches have been used in reducing orthodontic pain.
In Poland it is included, together with menthol and zinc oxide, in the liquid powder (not to be confused with the liquid face powder) used mainly after mosquito stings. Today's ready made Pudroderm was once used there as pharmaceutical compound.
Benzocaine is commonly found, particularly in Britain, as an impurity in street cocaine. Whilst giving a numbing effect similar to cocaine on users' gums it does not actually produce the effects of cocaine. But in terms of an orally based saliva drug test benzocaine can and has been mistaken for a false positive for cocaine.


To make sure that the right amount of medication is given, and to avoid touching the ear with the dropper, have another person insert the drops if possible. To lower the risk of dizziness, hold the container in your hand for a few minutes to warm it. To apply ear drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your ear or any other surface. Lie on your side or tilt the affected ear upward. Hold the dropper directly over the ear, and place 4 to 5 drops into the ear canal or as directed. To help the drops roll into the ear of an adult, hold the earlobe up and back. In children, hold the earlobe down and back. Keep the head tilted for about 2 minutes, or insert a soft cotton plug if so directed. Repeat for the other ear if so directed. Do not rinse the dropper. Replace the cap after use. Repeat this procedure every 1 to 2 hours as needed or as directed by your doctor.
