Rexona is a deodorant brand manufactured by Anglo Dutch company Unilever. It was developed in 1908 by an Australian pharmacist and his wife. Currently, "Rexona" has at least 8 lines of deodorant. Each line features a specific quality sought in deodorants. For example, "Rexona" has a formula to eliminate white marks on dark clothing and a prodcut line developed for low-income consumers. "Rexona" products are created with "body-responsive technology." "Rexona" scientists recently noted that the body produces two types of sweat, one from over-heating and another from emotional stress. These two types of sweat generate different chemicals and odors from different glands in the body. Cooling sweat is created all over the body, but sweat from emotional strain is created in fewer, more specific sites, including under the arms. "Rexona" has a formula to address both types of sweat. The over-heating sweat formula was tested on people in a sauna. The emotional stress sweat was tested on people interrogated in a mean and fast-paced manner to answer riddles and sums.
Depending on the type of product, antiperspirants usually contain salts to actually reduce the flow of sweat from the skin. These salts work by dissolving in sweat and temporarily leaving a thin coating of gel over the sweat glands. This coating reduces the amount of sweat on the skin for a number of hours after the antiperspirant is applied. Aerosol and roll-on products will most likely contain ACH (Aluminium Chlorohydrate), whereas sticks, gels and other solid products are most likely to contain an antiperspirant salt called AZAG (Aluminium zirconium tetrachlorohydrex GLY). These salts provide the safest and most effective means of controlling sweat. Some people may be concerned about the use of aluminium in antiperspirants and other everyday products, believing that it can damage health. For example, it has been suggested that aluminium is a possible contributory factor for Alzheimer's disease. However, experts and research bodies including the Alzheimer's Society say there is no relationship between the two. As with previous publications concerning a supposed causal link between aluminium and Alzheimer’s disease, recent publications have reported on the presence of aluminium in the body of cancer patients. The overwhelming scientific evidence suggests that again no causal link exists between the presence of aluminium and the onset of the disease. The main source of aluminium found in the body comes from our diet and not from the use of antiperspirants, 99% of which passes through the digestive system unabsorbed. The small amount of aluminium that is absorbed into the body is rapidly excreted by the kidneys in urine. The U.S. Food and Drugs Administration have published a major study on the use of antiperspirant salts, which concluded that antiperspirants and their aluminium salts are safe.
Unilever's position on animal testing does not rule out testing its products on animals. Whereas "Rexona" is tested on humans, it is not certain as to whether or not animals are tested with the products first. Unilever claims to discourage animal testing and to have strict internal control procedures to reduce animal testing, however, they do test on animals when they find no other means to test their products. Unilever claims to be developing alternative methods to eliminate animal testing at an undetermined time in the future.
