ECOS Free & Clear is for people with strong sensitivities to fragrance, fabric softeners, or cellulose optical brighteners. The Ph for ECOS Free & Clear is neutral. No coloring is added. Because natural ingredients are used color and consistency may vary. ECOS Free & Clear can be used in front loaders and high efficiency wash machines. ECOS Free & Clear can be used in grey water systems and is septic system safe.
