    Product Description

    Dimethicone (PDMS) CAS 9016-00-6 is an inert silicone fluid with the repeat formula [Si(CH3)2O]n.

    Synonyms: Dimethylpolysiloxane; Polydimethylsiloxane; PDMS.

    CAS: 9016-00-6.

    Molecular formula: [Si(CH3)2O]n.

    It is supplied in a range of viscosities for formulation use.

    It is also called polydimethylsiloxane or dimethylpolysiloxane.

    It is mainly used as an emollient, slip agent, spreadability enhancer, and sensory modifier in skin care, hair care, creams, lotions, and personal care formulations.

    It is a raw ingredient for formulated products, not a finished cosmetic.

    In skin care it is used as an emollient and sensory modifier where compatibility and viscosity matter.

    In hair care it is used as a slip agent and spreadability enhancer depending on grade and formulation design.

    In creams and lotions it contributes to spreadability, slip, and sensory feel.

    It is also used in specialty personal care formulations subject to cosmetic-grade confirmation and regulatory review.

    Store in a cool, dry, well-ventilated area in tightly closed containers, away from strong oxidizers and extreme heat.

    Use appropriate PPE and prevent spills or contamination.

    Confirm the offered package, net weight, lot traceability, and transport requirements before dispatch, and follow the current SDS.

    Every batch is checked for appearance, viscosity at the specified temperature, refractive index, specific gravity, volatile content or non-volatile residue, and residual cyclosiloxane or heavy-metal data, with COA/TDS/SDS supplied per grade.

    Confirm appearance, viscosity grade, refractive index, specific gravity, packaging, and cosmetic or industrial grade as required.

    The page is an RFQ entry point and does not state stock, price, MOQ, or fixed lead time.

    For an RFQ, state the intended application, required grade, viscosity, quantity, packaging, destination, and document needs.

    FAQ - Technical & Supply Chain

    • Q:

      What is Dimethicone, and how is it identified?

      A: Dimethicone, also called polydimethylsiloxane or dimethylpolysiloxane, is an inert silicone fluid identified by CAS 9016-00-6 and repeat formula [Si(CH3)2O]n. It is supplied in a range of viscosities for formulation use. Confirm the CAS number, viscosity grade, appearance, and offered cosmetic or industrial specification before ordering.
    • Q:

      Where is Dimethicone mainly used?

      A: It is mainly used as an emollient, slip agent, spreadability enhancer, and sensory modifier in skin care, hair care, creams, lotions, and personal care formulations. It is a raw ingredient for formulated products, not a finished cosmetic. Confirm viscosity, compatibility, dosage, and the target sensory profile.
    • Q:

      Which specifications should be checked before ordering?

      A: Confirm appearance, viscosity at the specified temperature, refractive index, specific gravity, volatile content or non-volatile residue, and any residual cyclosiloxane or heavy-metal data. Cosmetic and industrial grades differ, so the target viscosity and end-use grade should be specified before sampling.
    • Q:

      How should Dimethicone be stored and handled?

      A: Store it in a cool, dry, well-ventilated area in tightly closed containers, away from strong oxidizers and extreme heat. Use appropriate PPE and prevent spills or contamination. Confirm the offered package, net weight, lot traceability, and transport requirements before dispatch.
