Basic Information

Product Description

Product Name：Octamethylcyclotetrasiloxane  

CAS No: 556-67-2

Form: liquid

Product Application

Synthesis of Silicone Polymers (Primary Application):

D4 is the basic raw material for producing linear polydimethylsiloxane (PDMS). Under strong acid or base catalysis, D4 can undergo ring-opening polymerization to form PDMS silicone oils, silicone rubbers, and silicone resins with different molecular weights.

Cosmetics & Personal Care Products:

Skincare Products:​ Such as creams, lotions, sunscreens, hand creams, etc., as an emollient, softening agent, and solvent, imparting a smooth, non-greasy feel to the skin while helping disperse other ingredients.

Haircare Products:​ Such as shampoos, conditioners, hair masks, styling products, etc., as a smoothing agent and antistatic agent, improving combability, shine, and anti-tangling properties of hair.

Antiperspirants & Deodorants:​ As a carrier and solvent, helping distribute active antiperspirant ingredients evenly.

Color Cosmetics:​ Such as foundations, eyeshadows, lipsticks, etc., as an emollient and solvent, improving product texture and application.

Textile Industry:

Softener:​ Used in fabric finishing to impart a soft, smooth hand feel, reduce friction, and improve wearing comfort.

Coatings & Inks:

Leveling Agent:​ Improves the leveling of coatings and inks, preventing cratering and orange peel effects.

Defoamer:​ Suppresses foam generation during coating production and application.

Additive:​ Enhances scratch resistance, abrasion resistance, and hand feel of coatings.

Electronics & Electrical Industry:

Insulating Oil:​ Used for impregnation of transformers, capacitors, and other electronic components, providing insulation, cooling, and moisture protection.

Mold Release Agent:​ Used in molding plastic, rubber, and other products to facilitate demolding.

Defoamers:

D4 and its derivatives can be used as defoamers in industries such as papermaking, fermentation, wastewater treatment, and oil extraction to suppress foam.

Other Uses:

Polishes:​ Used in automotive, furniture, and other polishing applications to provide gloss and protection.

Lubricant:​ As a base oil or additive for greases, providing lubricating properties.

Pharmaceutical Intermediate:​ Used in the synthesis of certain drugs or drug carriers.
