Nopal has been used in hospitals, clinics, schools and even at the home since the early 1900s, when the Italian chemist Alfredo Nopal introduced it as a simple, easy-to-clean cleaner for his beloved dog, Nopal.
Nowadays, it is widely used by health professionals and even many of their customers.
But Nopal’s reputation has been tarnished by allegations of corruption in the company, which has been linked to bribery, kickbacks and corruption.
Today, Noval’s reputation is tarnished as well.
But it is not just Nopal that has suffered.
Other cleaners, including Procter & Gamble, Pfizer, Johnson & Johnson, Unilever and other big brands, have also been accused of abusing their power.
Now the story of Nopal comes back to life, with a new team of investigators investigating a scandal that has engulfed the company for decades.
In this exclusive interview with the BBC’s James Forsyth, the company’s founder, John Coughlan, explains the current scandal and its long-term impact on the industry.
