CLEMSON UNIVERSITY – Tests to determine the rinseability differences between WONDER WASH and Liquid Tide. The graph was obtained from testing rinseability of cotton diapers during numerous wash cycles. Detergents were WONDER WASH and Liquid Tide. Also cycles were completed using water only (control). Conditions during the wash cycle were determined by AATCC Test Method #61. Observing the graph you will note that cotton diapers washed with Liquid Tide gained nearly 2% in weight in only 8 washings while the weights of cotton diapers washed in WONDER WASH and water remained basically unchanged. WONDER WASH rinsed out completely and Liquid Tide did not.

CLEMSON UNIVERSITY – The measured effect of multiple washings on the Flammability of Children’s Sleepwear in accordance with the Consumer Product Safety Commission’s Test 16 CFR 1615/1616 and ASTM Test D4723 Clemson University test results showing char length measured in centimeters after a three second exposure to an open flame, after the given number of washings. WONDER WASH improves the flame retardant properties of children sleepwear. After 17th wash and dry cycle, the samples only melted with no residue. Even when the flame was held longer than the specified three seconds, there was still no burning or charring – only melting. Four other products were tested – Ivory Snow, Tide, Baby Soft and Dreft – but only WONDER WASH improved and continued to improve the flame-retardancy of the fabrics tested.

Procedure: Test fabrics submitted by Carter Manufacturing © were washed with various detergents, dried and exposed to open flame for 50 cycles. Results were measured by char length at each cycle.

Results: Charlie’s Soap continued to improve the flame retardant properties after each washing to the point where the fabric would not catch fire at all. No other detergent tested improved the flame retardant properties of children’s sleepwear at all.

This test was performed with 100% cotton cloth diapers. Poor rinsability was indicated by a weight gain after controlled washing and drying.

Diapers washed in Tide Liquid (at recommended levels) gained nearly 2% in weight after only 8 washings. Those washed in Charlie’s Soap (at recommended levels and 4 times recommended levels) gained no measurable weight at all.

It is reasonable to assume that hypo-allergenic fabrics washed in Charlie’s Soap Laundry Liquid, which is shown to leave no irritating residues, will surely remain so when washed with Charlie’s Soap.
