[10] Under Reimann's descendants the business grew rapidly in the latter half of the 20th century: it acquired Coty, Inc., a North American beauty products manufacturer, in 1992.

Bart Becht became CEO of the new company and has been credited for its transformation, focusing on core brands and improving efficiency in the supply chain.

The three main brands acquired were Nurofen's analgesics, Strepsils sore throat lozenges, and Clearasil anti-acne treatments.

[28] In September 2011, Bart Becht retired as CEO of Reckitt Benckiser, being replaced by executive vice-president of Category Development, Rakesh Kapoor, who had played a key role in recent acquisitions.

[29] On 27 August 2011, Reckitt recalled all remaining stock of its major analgesic product, Nurofen Plus, after packs were found to contain an antipsychotic drug.

[32][33] In December 2014, Reckitt spun off its speciality pharmaceuticals business, which produces Suboxone (an opioid withdrawal medication), into a separate company named Indivior.

[39] Following the acquisition of Mead Johnson, Reckitt Benckiser split its business into two divisions: consumer healthcare, and home and hygiene.

[40] In July 2017, McCormick acquired Reckitt's food brands, including French's Mustard & Frank's RedHot, for $4.2 billion, subject to regulatory approval.

[44] Narasimhan developed a turnaround strategy designed to rejuvenate the company "following a series of missteps and lacklustre growth that marked the final years of his predecessor".

[46] On 1 September 2022, Reckitt announced that Narasimhan had chosen to resign as CEO, citing "personal and family reasons",[47] and would relinquish his position at the end of the month.

[45] Senior Independent Director Nicandro Durante was appointed to serve as CEO on an "interim"[50] basis "while the board considers a longer-term replacement".

[53] As of 2020, Reckitt's directors were: Christopher Sinclair (chairman), Laxman Narasimhan (CEO), Jeff Carr (CFO), Andrew Bonfield, Nicandro Durante, Mary Harris, Dr. Mehmood Khan, Dr. Pamela Kirby, Sara Mathew, Elane Stock, and Warren Tucker.

[54] As of 2020, members of the executive committee were: Laxman Narasimhan (CEO), Rupert Bondy (General Counsel), Jeff Carr (CFO), Kris Licht, Aditya Sehgal, Ranjay Radhakrishnan, and Harold van den Broek.

[61] Earthjustice contacted several companies in September 2008 requesting that they comply with a 1971 law requiring them to disclose the ingredients in their products and make available any associated health or safety studies.

[62] Earthjustice eventually lost the case, after which it lobbied the New York State Department of Environmental Conservation, which in 2018 unveiled new requirements for manufacturers of cleaning products to publicly detail their ingredients.

In 2011, the use of PHMG was dropped when the Korea Centers for Disease Control and Prevention (KCDC) published a report showing a link between the compound and lung damage and deaths.

[66] Sometime after the release of the KCDC report, prosecutors in South Korea opened an investigation into the companies selling the disinfectants, which increased its pace in January 2016.

In one advert, he places a copper English one penny coin in Cillit Bang to demonstrate the product's cleaning ability to remove staining.

International versions of the advert use different presenters, known as Martin Grellis in Australia and New Zealand, and Dan Dolan in North America, although some spots feature Neil Burgess as Barry Scott.

[68] In 2005 advertising agency Cohn & Wolfe was contracted by Reckitt to operate a blog as the fictional character Barry Scott as a viral marketing platform.

In the parodies, the host "Derek Baum" (played by Serafinowicz) markets a product called Kitchen Gun, which is a firearm that the host uses to blast away at kitchen surfaces and appliances, cleaning and damaging them at the same time,[74] and Toilet Grenade, a hand grenade covered in white paint that demolishes the toilet bowl to eliminate limescale and germs.

[75] In 2008, the BBC's Newsnight accused Reckitt Benckiser of attempting to delay the introduction of a competitive, generic version of one of its most popular products, Gaviscon, a treatment for heartburn and gastroesophageal reflux disease.

[78] The Independent quoted Warwick Smith, director of the British Generic Manufacturers Association: "The sort of evergreening alleged by Newsnight can cost the NHS tens of millions of pounds with no patient benefit.

[83] In 2014, the Autorité de la concurrence in France found that Reckitt had colluded with 12 other multinational companies (Colgate-Palmolive, Henkel, Unilever, Procter & Gamble, Sara Lee, SC Johnson, Bolton Solitaire, Laboratoires Vendôme, Gillette, L'Oréal, Beiersdorf and Vania) to fix the prices of popular personal hygiene products; the fine of around €950 million was the largest ever imposed by the agency.

[86] In 2008, the United States Environmental Protection Agency (EPA) announced a decision to remove second-generation anticoagulant rodenticides from store shelves, leaving the products available for purchase only by US licensed applicators.

In 2011, Reckitt Benckiser makers of d-CON products initiated a legal challenge to the EPA expected to take several years to resolve.

Early in 2014, California State Department of Pesticide Regulation ruled that anticoagulant rat poison sales would be restricted beginning on 1 July 2014.

In April 2022, the company announced plans to transfer ownership of its Russian business to a third party or local employees but did not complete the process as of 2024.

[93][94] Trading data reveals that Reckitt Benckiser continues to export products to Russia, raising concerns about its commitment to disengaging from the market.
