Two of the world's biggest household and personal care products firms see the most strength coming from outside of the United States, particularly China and Brazil, top executives at both companies told CNBC this week.
At Kimberly-Clark, which reported slightly better-than-expected earnings on Friday, Chairman and CEO Thomas Falk said, "Our international emerging market business did great. We had double-digit top-line there. Markets like China — our China diaper business was up 50% in the quarter." Brazil was up 10 percent. The company's brands include Huggies and Scott.

The BRICs (Brazil, Russia, India and China) were also a bright spot at Procter & Gamble, which announced profits on Friday that handily topped Wall Street estimates. P&G is behind brands like Tide and Pampers.
"Our developing market business is very healthy," said P&G Chief Financial Officer Jon Moeller. "Over 20 percent [growth] in Brazil and India" and high single-digits in China, which he predicted will accelerate. "So that continues to be where a disproportionate amount of growth is coming."

Both P&G's Moeller and Kimberly's Falk, who appeared on "Squawk Box" right after their companies reported earnings, see the American consumer as a bit wary.
"It feels a little bit like the consumer's going sideways," Falk said. "So CEO mom is still shopping from a list. She's still careful."
Moeller of P&G said, "The [U.S.] consumer is definitely hanging in there. We haven't seen an inflection point in the market growth rates yet, but we also haven't seen any deterioration. So it's reasonably good."
Meanwhile, Procter & Gamble and Kimberly-Clark predicted commodity prices and foreign exchange fluctuations would affect their operations in opposite ways.
"Commodity costs in 2012 were a tail wind, but we had currency that was a headwind. And they've basically just about offset each other," Falk of Kimberly said. "In 2013, we see that flipping around a little bit" because of pulp and fiber related costs.
At P&G, Moeller said, "There are other tailwinds related to the broader macro environment. Much more benign commodity environment than we saw in the last two years. Certainly a better environment from a foreign exchange standpoint."
Both companies also stressed the importance of how product innovation can create value for their consumers, who can find similar off-brands for less money.
