As far as i know the compound mentioned at 1:35 is Tetrahydrozoline Hydrochloride. It is a decongestant used to relieve redness in the eyes caused by minor eye irritations (such as smog, swimming, dust, or smoke). It belongs to a class of drugs known as sympathomimetic amines. It works by temporarily narrowing the blood vessels in the eye.
