The Covid-19 pandemic led to a surge in demand for Reckitt Benckiser Group's Lysol and 3M's N95 masks.

Reckitt Benckiser Group PLC is capitalizing on booming interest in hygiene during the pandemic, launching a new business selling its cleaning products and expertise to the travel and hospitality industries.

For the second-quarter, sales in the British company's hygiene arm rose more than 19% on a like-for-like basis from the year earlier. The gain was driven by North America, where Lysol sales jumped over 70%.

3M Co. suffered a sharp sales drop while many factories, offices and dentists remained closed, offsetting gains from high demand for N95 masks and home-improvement supplies.

The U.S. maker of industrial, safety and consumer products said the global economy appeared to be recovering. Total sales in July were higher than sales through this portion of the month last year, and adjusted sales in China increased 3% in 3M's second quarter, which ended in June.

3M has doubled production of its N95 masks this year to meet skyrocketing demand from health-care workers. 3M said it produced nearly 800 million respirators and N95s -- so-called because they block 95% of very small particles -- in the first half of this year globally and has distributed about half of them in the U.S.

Still, face masks make up a small part of 3M's business, which spans from advanced wound-care products to Scotch tape and industrial sandpaper.
