Some interesting things:
Colgate-Palmolive has animal testing undertaken for it by outside contractors. A few years ago, BUAV recently uncovered details of an experiment carried out for the company by Columbia University in which guinea pigs were locked into small plastic tubes and a strong solution of surfactant was applied for four hours a day for three days, causing cracked and bleeding skin on the animals.
Smithkline-Beecham
The company its own animal testing facilities and it has been accused of unnecessary cruelty in housing its animals. In 1990, an undercover National Anti-Vivisection Society worker reported baby mice having their toes removed, beagles kept in metal pens with concrete floors and no bedding, and dogs being transported packed two in a crate.
Proctor and Gamble
In July 1991, BUAV revealed that P&G had conducted tests on about 300 guinea pigs to determine irritancy and allergic sensitivity to sunscreen ingredients. Human data was already available. In 1992, using US government records, 'In Defence of Animals' reported that P&G had increased its use of dogs, hamsters and ferrets between 1986 and 1989. Total animal use is estimated at about 50,000 per year.
