🧴 Whitening Additive Detergents for Washing Machines – Production, Formulation and Properties
Overview:
Whitening Additive Detergents for Washing Machines are specialized booster products developed to intensify the whitening effect of conventional laundry detergents.
These formulations enhance brightness, stain removal, and optical clarity by introducing additional bleaching, brightening, and anti-graying agents into the washing process.
They are designed for automatic washing machines and can be used alongside standard detergents, particularly for white cotton, linen, and mixed fabrics.
Modern whitening additives are phosphate-free, enzyme-compatible, and safe for both fabrics and washing machines, providing brilliant whiteness without fiber wear or yellowing.
Production and Formulation:
The Whitening Additive Detergent Manufacturing Process involves blending oxygen-releasing bleaching agents with stabilizers, builders, and optical brighteners under controlled conditions.
The resulting powder dissolves rapidly in both hot and cold water, releasing active oxygen and optical enhancers during the washing cycle.
Typical formulation components include:
-
Active Oxygen Source: Sodium percarbonate or sodium perborate – for oxidative whitening.
-
Activator: TAED – enhances oxygen release at low temperatures.
-
Optical Brighteners: Stilbene or coumarin derivatives – for bright, reflective whiteness.
-
Builders: Sodium carbonate, zeolite, or citrate – improve cleaning and water softening.
-
Anti-Graying Agents: CMC or acrylic copolymers – prevent dirt redeposition.
-
Stabilizers: Sodium silicate or magnesium silicate – increase storage stability.
-
Perfume and Dye (optional): For fragrance and product identity.
Manufacturing steps:
-
Dry Mixing: All powdered raw materials are uniformly blended.
-
Liquid Addition (optional): Perfumes or colorants may be lightly sprayed.
-
Granulation and Screening: Ensures even particle size and free-flowing texture.
-
Quality Control: Tests for active oxygen content, moisture, and whitening performance.
-
Packaging: Packed in moisture-resistant containers for long shelf life.
