Makers of household staples from diapers to toilet paper are set to raise prices again this year after already hiking prices in 2018, hoping to offset higher commodity costs and boost profits.

Church & Dwight Co. recently increased prices for about one-third of its products, including Arm & Hammer cat litter and baking soda, and some OxiClean cleaning products.

“The good news is that competitors are raising [prices] in those categories as we speak,” Church & Dwight Chief Executive Matthew Farrell said on a conference call last week when the company reported higher quarterly sales and lower profits.

The company is now discussing more price increases with retailers, including for personal-care products, Mr. Farrell told analysts Tuesday.

Church & Dwight is one of several consumer-goods companies, including Procter & Gamble Co. , Colgate-Palmolive Co. and Clorox Co. , that have raised prices—or pledged to do so—in response to higher costs of raw materials and transportation, as well as unfavorable foreign-currency swings.
