Tide Detergent is being stolen from store shelves nationwide..... In Orange County, an attempted Tide theft led to a high-speed chase that included the thief crashing his SUV into an ambulance. Last year, for the first time, detergent made the National Retail Federation’s list of most-targeted items. Says Joseph LaRocca, founder of the trade group RetailPartners, who helped compile the report: “Tide was specifically called out.”

What do thieves want with so much laundry soap? . Tide bottles have become ad hoc street currency, with a 150-ounce bottle going for either $5 cash or $10 worth of weed or crack cocaine. On certain corners, the detergent has earned a new nickname: “Liquid gold.” The Tide people would never sanction that tag line, of course. But this unlikely black market would not have formed if they weren’t so good at pushing their product.

Shoppers have surprisingly strong feelings about laundry detergent. In a 2009 survey, Tide ranked in the top three brand names that consumers at all income levels were least likely to give up regardless of the recession, alongside Kraft and Coca-Cola. That loyalty has enabled its manufacturer, Procter & Gamble, to position the product in a way that defies economic trends. At upwards of $20 per 150-ounce bottle, Tide costs about 50 percent more than the average liquid detergent yet outsells Gain, the closest competitor by market share (and another P&G product), by more than two to one. According to research firm SymphonyIRI Group, Tide is now a $1.7 billion business representing more than 30 percent of the liquid-detergent market.
