    Product Description

    Calcium Lignosulfonate CAS 8061-52-7 is a water-soluble calcium salt derived from lignin.

    Synonyms: Calcium lignosulfonate; calcium lignin sulfonate; lignosulfonic acid calcium salt.

    CAS: 8061-52-7.

    Molecular formula: Not specified (lignosulfonate polymer).

    It is supplied as powder or liquid, with grades specified by solids and pH.

    It is used as a dispersant, water-reducing admixture, binder and processing aid.

    In concrete, it adsorbs onto cement particles, improving workability and reducing water demand.

    Depending on dosage and cement chemistry, it can also provide a mild set-retarding effect.

    It is also used in mineral, carbon, ceramic and fertilizer granulation, and in dust-control or soil-stabilization programmes.

    Calcium lignosulfonate differs from sodium lignosulfonate by the counter-ion.

    The calcium form is often reported to resist hard-water precipitation better.

    Powder and liquid grades are defined by solids basis, pH and impurity controls rather than by name alone.

    For selection, specify powder or liquid form, solids basis, pH, water-insoluble matter, reducing sugars, calcium level and target application.

    Store in closed containers and follow the applicable SDS for handling.

    Use suitable PPE when handling to avoid dust exposure and skin or eye contact.

    Confirm solids, pH and physical consistency on the COA.

    Confirm grade, packaging, and specification as required.

    FAQ - Technical & Supply Chain

    • Q:

      What is Calcium Lignosulfonate CAS 8061-52-7?

      A: Calcium lignosulfonate is a water-soluble calcium salt derived from lignin. It is used as a dispersant, water-reducing admixture, binder and processing aid in construction and industrial applications.
    • Q:

      How does calcium lignosulfonate work in concrete?

      A: It adsorbs onto cement particles and disperses them, improving workability and reducing water demand. Depending on dosage and cement chemistry it can also provide some set-retarding effect, so the response should be checked in a mix trial.
    • Q:

      How does calcium lignosulfonate differ from sodium lignosulfonate?

      A: The two products belong to the same lignosulfonate family but have different counter-ions. Calcium lignosulfonate is often reported to resist hard-water precipitation better, while sodium lignosulfonate may show different dispersion flexibility and solubility behaviour.
    • Q:

      What are the non-concrete uses of calcium lignosulfonate?

      A: It is used as a binder or dispersant in mineral, carbon black, ceramic and fertilizer granulation, and in dust-control or soil-stabilization programmes. It can also serve as a pellet binder in feed or bulk-material processing.
    • Q:

      What should a calcium lignosulfonate specification include?

      A: State powder or liquid form, solids basis, pH, water-insoluble matter, reducing sugars, calcium level, moisture for powder grades and the target application. Dosage should be confirmed in the actual cement or process system rather than copied from a general reference.
