Liquid sodium silicate used in detergents primarily leverages its properties such as alkaline buffering, water softening, anti-redeposition, and corrosion inhibition; it serves as a crucial functional additive in laundry powders, liquid detergents, and soaps.
When selecting liquid sodium silicate for detergent applications, the most critical parameter is its modulus.
The modulus represents the molar ratio of silicon dioxide (SiO₂) to sodium oxide (Na₂O) within its chemical structure, and it determines the product’s performance characteristics and pH value.
For detergent manufacturing, the modulus of liquid sodium silicate typically falls within the range of 1.3 to 4.0; however, the specific range you choose depends on whether your final product is a liquid detergent or a powdered detergent.
Modulus Ranges
I: High Modulus (Approx. 3.0 – 4.0)
3.2 – 3.4: Possesses strong alkaline buffering capacity, enabling it to stably maintain the pH level of the washing solution.
3.41 – 3.70: Exhibits excellent anti-redeposition properties, effectively preventing removed soil and dirt from re-adhering to clothing fibers.
Recommended Applications: Laundry powders, soaps, and other powdered or solid detergents.
II: Medium-to-Low Modulus (Approx. 1.5 – 3.0)
2.2 – 2.64: Offers superior water solubility and fluidity, making it easier to blend uniformly with other liquid ingredients.
2.8 – 3.4: Possesses strong water-softening capabilities, effectively chelating calcium and magnesium ions present in the water.
1.5 – 2.4:
Recommended Applications: Liquid laundry detergents, dishwashing liquids, and other liquid-based cleaning products.
✅ How to Make a Quick Decision?
Manufacturing Laundry Powder: Prioritize high-modulus products (e.g., 3.0 – 3.4).
Manufacturing Liquid Detergent: Prioritize medium-to-low modulus products (e.g., 2.2 – 2.6).
Manufacturing Phosphorus-Free Eco-Friendly Products: Consider products within the 2.8 – 3.4 range, as these are frequently utilized in phosphorus-free additive formulations.
Purchasing Tip: When contacting manufacturers, in addition to the modulus, do not forget to verify the Baumé degree (concentration) and impurity levels (such as iron content and water-insoluble matter); these factors significantly impact the final quality of the detergent.
Do you primarily manufacture liquid laundry detergents or laundry powders?
