2. Jaypol™ HN70 polymer for Laundry Detergents
Overview
Manufacturers of powder laundry detergent may inhibit mineral salts from
adhering to fabrics in the wash cycle with Jaypol HN70 polymer.
The polymer works by modifying the tendency of mineral salts to crystallize in water
Particularly in powder laundry detergent, where sodium carbonate builder reacts with calcium in the wash water to form calcium carbonate, Jaypol HN70 polymer may be used to inhibit fabric encrustation
Including Jaypol HN70 polymer in powder laundry detergent formulations enables formulators to use builder such as sodium carbonate and virtually eliminate problems such as mineral salts encrustation, loss of color vibrancy, ‘graying’ of clothing and loss of texture

3. Jaypol™ HN70 polymer for Laundry Detergents
Overview
A maleic-based copolymer, Jaypol HN70 polymer is designed to
function well in stressed wash water conditions that may include
high pH/alkalinity, high levels of electrolytes and minerals.
Helps to maintain the original look and feel of clothing
Is compatible with common laundry detergent additives
Substantially reduces mineral encrustation in the wash cycle without negatively impacting surfactant functionality

Function
A stable polymer technology in cold, warm and hot water wash conditions, Jaypol HN70 encrustation inhibitor generally outperforms polyacrylate technology. Typical Properties Appearance Clear colorless liquid Bulk viscosity About 60 cP (Brookfield RVT sp 50 rpm, 25°C) Water soluble Solids content About 40% pH About 8.4 Molecular weight Very low

Efficacy tests
Factors such as hard water conditions and in situ formation of calcium carbonate in the wash water can be detrimental to clothing. In tests with black cotton knit fabric washed in hard water conditions using a standardized detergent formulation containing Jaypol HN70 encrustation inhibitor, the polymer helped to substantially maintain both original look and feel.

Efficacy tests - protocol
Fabrics:
Black cotton knit fabric (Testfabrics 460B) was scoured in 400 ppm nonionic surfactant prior to use.
The fabric was cut to 5” x 5” swatches and 5 swatches were included in each test. The total weight of
the swatches was approximately 20 g.
Water:
Hard water was prepared by dissolving calcium chloride and magnesium sulfate in distilled water. A
3:1 molar ratio of Ca to Mg was used.
Detergents:
Detergents were prepared with concentrations of the following: 10% NaLAS, 5% Tomadol 25-7, 5%
Sodium silicate 2:1, soda ash as noted, and 0, 0.5, 1, 2.5, and 5% active polymers with the balance
being sodium sulfate. The detergent was dissolved at 10% prior to addition to the Terg-o-tometer
buckets. The polymers were diluted to 10% and added to the detergent just prior to addition to the
bucket. The detergent was added at a concentration of 2 g/liter of the active detergent.
Washing conditions:
1 L of water
80 RPM
10 minute wash, 5 minute rinse
Addition order: water, cloth, detergent
Wring to 100% water pickup after rinse cycle, air dry between cycles
5 cycles

Summary
Modifies crystal habit of mineral salts in wash water to substantially reduce encrustation onto fabrics
Maleic rich copolymer technology generally offers better inhibitor performance than polyacrylate technology
Is ideal for use in powder laundry detergent containing carbonate builder
Helps to substantially maintain the look and feel of fabrics washed in hard water “stressed” conditions
