<p>A process for forming a fabric conditioning composition includes the steps of providing a fabric conditioning concentrate; providing water; and providing preneutralized 1,1-hydroxyethane diphosphonic acid. The fabric conditioning concentrate, water, and the pre-neutralized 1,1-hydroxyethane diphosphonic acid are combined in a mixer to form a fabric conditioning composition having a conductivity of from about 700υS/cm to about 3,000 υS/cm. The fabric conditioning concentrate includes a hydrolyzable fabric conditioning active, while the pre-neutralized 1,1-hydroxyethane diphosphonic acid is pre-neutralized to a pH of from about 2.1 to about 2.4. The fabric conditioning composition formed by this process possesses significantly improved viscosity and phase stability.</p> |
