Two years after the recession officially ended, U.S. shoppers are still pausing before spending more on items from updated toothpastes to the latest lipsticks as food and gasoline prices have risen.

The North American market is only worth roughly 18 percent of sales at both Avon and Colgate, excluding the latter company's Hill's pet food unit. Latin America, meanwhile, accounts for 47.2 percent of Avon's revenue and 29 percent of Colgate's sales.
Colgate earned $622 million, or $1.26 per share, in the second quarter, up from $603 million, or $1.17 per share, a year earlier. Sales rose 9.7 percent to $4.19 billion.
