• Soap Berry Liquid Detergent: Efficacy Test

NaturOli’s soap nut liquid detergent goes toe to toe with leading chemical detergents in independent laboratory testing to compare cleaning power. This is the first time in history an independent US laboratory detergent comparison included soap nuts.

Recently documented (June, 2009) via laboratory efficacy studies, soap nuts and saponin are proved equivalent in cleaning power to the some of the most popular mainstream synthetic chemical detergents on the market. The testing was for cleaning power only. There is no consideration given to the “mile long” list of additional benefits (either health or environmental) from the use of soap berries and saponin. For most, soap nuts sound to good to be true – but this is real. These are the facts. Here is the proof.

In June of this year, a diluted version of NaturOli’s Extreme 18X concentrated laundry soap was provided to Specialized Technology Resources (STR) in Canton, Massachusetts for comparative testing and analysis. The dilution of the 18X was done to approximate a one-ounce to one-ounce single load comparison. One ounce of “pure” Extreme 18X will wash approximately six to 12 loads. A full ounce of Extreme 18X would not make for a realistic comparison. It was diluted to equate to a single load dosage to compare apples to apples.

Comparisons were made against Tide 2X Ultra, Tide Free 2X Ultra, Seventh Generation Free and Clear 3X Concentrate and Method’s 3X Detergent Concentrate. Tests were conducted using a cold water (70F), normal wash cycle and used top loading vertical axis washing machines.

In the final analysis it is quoted by STR, “At approximately a 35% lower Use Level than both the Tide and Seventh Generation products and at the same Use Level as the Method product (NaturOli’s liquid soap nut detergent) demonstrated approximately 98% Tide’s, Seventh Generation’s and Method’s Overall Soil Removal Capability.”

That’s using 35% less product in the comparison with Tide and Seventh Generation. The tests were conducted using cold water with vertical agitation – one of saponin’s most difficult scenarios for maximum effectiveness. Amazing! Of the numerous tests, even with additional enzyme boosters by the competitive brands, the very lowest comparative results proved 91-93% effectiveness. There are currently no enzyme boosters whatsoever added in NaturOli’s Extreme 18X saponin laundry soap. This is a due to NaturOli maintaining the product’s purity.

Virtually across the board in every single test the results were comparable. The tests compared soiling by dust, clay, coffee, cosmetics, grape juice, grass, blue ball point pen, spaghetti sauce, motor oil and more. Test evaluated results on fabrics such as cotton, polyester and blends.

Hands down, this is a major victory for saponin over synthetic chemical detergents. Please don’t think that the supposedly “green” products that the saponin detergent was compared are actually “green”. Read the ingredients for yourself. They are far from it. SLS is still a primary ingredient.

Bottom line: The first of NaturOli’s saponin-based detergents went head to head with the leading detergents on the market and the jury called it a draw. Given that the emphasis of saponin-based products is placed on purity from all hazardous chemicals, this is a monumental achievement.
