BIO-SOFT® N91-6 is an approved ingredient on www.cleangredients.org. For further information,
visit www.cleangredients.org. BCI = 68. Total BCI (Biorenewable Carbon Index) was calculated
only for the Stepan surfactants used in this formulation. For further information on Stepan's BCI,
visit www.stepan.com. This formulation does not meet the California Air Resource Board (CARB)
VOC regulation for Consumer Products. "Consumer" is defined by CARB as any person who
seeks, purchases, or acquires any consumer product for personal, family, household, or
institutional use. For U.S. formulators, STEPOSOL® MET-10U is a low vapor pressure VOC
(LVP-VOC), therefore its contribution to the VOC calculation is zero. STEPOSOL® MET-10U does
not contribute to the VOC calculation because of its high boiling point and low vapor pressure.
Before using on plastic, hard or painted surfaces, spot test on an inconspicuous area first.
