What is Dimethicone, and how is it identified?

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.

Where is Dimethicone mainly used?

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.

Which specifications should be checked before ordering?

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.

How should Dimethicone be stored and handled?

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.

Dimethicone CAS 9016-00-6

Dimethicone CAS 9016-00-6 is a silicone-based formulation ingredient widely used in personal care and cosmetic systems where smooth skin feel, lubricity, spreadability, and water-resistant sensory performance are required. Where a hydroxyl-terminated silicone gum is specified, Dimethiconol is a related formulation raw material to evaluate. As a supplier and manufacturer, we support bulk supply for dimethicone used in creams, lotions, hair care, skin care, and related formulation systems. Standard packaging, document support such as COA, TDS, and SDS / MSDS, as well as sample discussion and sourcing support, are available based on project requirements. Its application suitability should be confirmed through formulation evaluation according to the target system and performance expectations.

Typical Applications

Dimethicone CAS 9016-00-6 is commonly used in:

skin care formulations where improved slip and a soft after-feel are needed
hair care products where conditioning and lubricity are important
creams and lotions requiring better spreadability and sensory balance
cosmetic and personal care systems where silicone-based texture adjustment is desired
formulation systems designed for smoother application and reduced tackiness

Application suitability should be confirmed through formulation testing, especially when viscosity, compatibility, and target sensory profile are critical.

Functional Role in Formulations

In formulation systems, dimethicone is commonly selected for functions such as:

emollient effect
improved slip and lubricity
enhanced spreadability
smoother skin feel
support for formulation aesthetics and sensory profile

The exact performance depends on grade selection, viscosity, dosage, and compatibility with the rest of the formulation system.

For silicone systems requiring reactive Si-H functionality rather than an inert silicone fluid, Hydrogen Silicone Oil is a separate material used in crosslinking and modification formulations.

Packaging

Available in standard packaging for bulk supply.
Packaging options can be discussed based on grade selection, order quantity, and transport requirements.

Storage

Store in a clean, dry, and well-ventilated area in tightly closed original packaging.
Avoid contamination during handling.
Detailed storage and handling guidance should follow the applicable SDS and product documentation.

Documents Available

Documents for Dimethicone CAS 9016-00-6 can be supported upon request, including:

COA
TDS
SDS / MSDS

Public supplier product pages for this CAS also indicate routine document support such as COA and safety documentation.

Supply Ability / Custom Support

We supply Dimethicone CAS 9016-00-6 for customers seeking silicone-based formulation ingredients for personal care and related industrial sourcing projects. Support can be discussed for:

bulk supply
standard packaging
sample evaluation
grade and viscosity discussion
formulation-oriented sourcing support
export documentation coordination

The final product selection should be based on the intended formulation type and technical requirements.
