All Nellie’s products are biodegradable, keeping the environment as spotless as your clothes. The entire Nellie's line is free of harmful toxins, phosphates and synthetic fragrances. We take the bad stuff out, not put it in. Our products are HE machine-certified and made with no fillers. Nellie’s is more concentrated than other detergents so only one tablespoon is needed for a regular load. The fact is, more cleaning power can be packed into powder! Fabrics need to rub against each other in your machine to effectively clean. It’s this friction, combined with a surfactant, that helps penetrate dirt and stains – too many bubbles will prevent this from happening. Nellie’s rinses completely clear, leaving nothing behind. No perfumes, no optical brighteners, no solid synthetics. Your skin, environment and machine are left naturally clean!
