This seems to be a certainty. Detergents are chemical surfactants derived from crude oil. With one exception, the basic building blocks of surfactants are all derived from crude oil. Unless detergent manufacturers choose to reduce their profit margins to keep the cost of detergent low, you will pay more and more for detergent, just as you pay more and more to fill up your car with fuel. As the cost of raw materials for detergent rises, so too do the costs for end users. Furthermore, their plastic containers (which are made from just 25% recycled plastic) are made from petrochemicals, and shipping these bulky and heavy bottles costs more due to record-high fuel prices. These additional costs are ultimately passed on to the end user as well.
