Wool washing powder is engineered to clean woolen fabrics while preserving their softness, elasticity, and color. Wool fibers are delicate and prone to felting or shrinking when exposed to harsh chemicals or extreme temperatures, so the powder uses gentle, low-foam surfactants and a slightly acidic pH (typically 3.5–5.5) to match wool’s natural acidity. This helps prevent fiber swelling and damage during washing. The formula often incorporates lanolin or plant-based conditioners to replace the wool’s natural oils, keeping the fabric supple and reducing static. Enzymes may be included to break down protein-based stains like sweat without harming the fibers. Wool washing powder is designed for use in cool water and gentle cycles, and it rinses completely to avoid residue that could cause stiffness. It’s ideal for cleaning wool sweaters, blankets, and accessories, maintaining their luxurious feel and preventing pilling or deformation.
