Liquid fabric conditioner composition and method of use

Method of conditioning fabrics, comprising:

• (a) washing cotton fabric with a wash pH greater than 9,
• (b) contacting the washed fabric with a composition consisting of an amino-functional silicone, an amidoamine quaternary ammonium, water, salt, viscosity controlling agent and fragrance;
• and
• (c) drying said fabric so that the fabric temperature is 200 degrees F. or greater, wherein the delta b* of cotton fabric is greater (more negative) than the delta b* of a control when subjected to at least 15 cycles, a cycle is comprised of a wash step according to step (a) followed by a conditioning step according to step (b) and drying step according to step (c) and the softness of the fabric does not decrease.

A method of treating fabric, the method comprising:

• (a) allowing cotton fabric to contact a liquid fabric conditioning composition, wherein said composition consists of:
• (i) an amidoamine quaternary ammonium compound;
• (ii) an amino-functional silicone compound;
• (iii) water;
• (iv) salt;
• (v) viscosity controlling agent and (vi) fragrance;
• and (b) subjecting said conditioned fabric to the inside of an industrial dryer during a drying operation wherein the fabric temperature is 200 degrees Fahrenheit or greater, and the delta b* of said fabric is greater (more negative) than the delta b* of a control after 15 cycles, wherein a cycle comprises a wash step, a treating step according to step (a), and a drying step according to step (b).

Method of conditioning fabrics, comprising:

• (a) washing cotton fabric in a high alkaline detergent;
• (b) contacting the cotton fabric with a liquid composition consisting of an amino-functional silicone, and amidoamine quaternary ammonium, water, salt, viscosity controlling agent and fragrance;
• and
• (c) drying said fabric at a temperature of greater than 200 degrees F., wherein the delta b* of cotton fabric is greater (more negative) than the delta b* of a control when subjected to at least 15 cycles, a cycle is comprised of a wash step according to step (a) followed by a conditioning step according to step (b) and drying step according to step (c) and the softness of the fabric does not decrease.

Method of conditioning fabrics, comprising:

• (a) washing cotton fabric with a wash pH greater than 10,
• (b) contacting the washed fabric with a composition consisting of an amino-functional silicone, an amidoamine quaternary ammonium, water, salt, viscosity controlling agent and fragrance;
• and
• (c) drying said fabric at a temperature of greater than 200 degrees F., wherein the delta b* of cotton fabric is greater (more negative) than the delta b* of a control when subjected to at least 15 cycles, a cycle is comprised of a wash step according to step (a) followed by a conditioning step according to step (b) and drying step according to step (c) and the softness of the fabric does not decrease.
