Product DescriptionProduct Introduction:1. Chemical name: Octamethylcyclotetrasiloxane2. Alias: D4Product Description:1. This product is clear, tasteless, odorless, non-greasy and non-irritating. Cyclotetrasiloxane is a volatile polydimethylsiloxane, mainly composed of cyclotetrasiloxane.It has good spreading and lubricating properties as well as unique volatility, and is widely used as a base oil in personal care products.It is also an important intermediate for silicon materials, which can be ring-opened and polymerized into organosilicon polymers under acid-base catalysis. It is an important raw material for silicone products.Product Features:1. Colorless oily liquid, sensitive to moisture; miscible with organic solvents, insoluble in water, volatile carrier, compatible with various cosmetic ingredients, low surface tension, anti-sticking, good spreadability, no oil residue or sediment.Viscosity(cSt at 25°C)2.4AppearanceColorless and transparent liquidSpecific Gravity (25 ℃)0.95Cyclotetrasiloxane(D4) content (%)> 96Flash Point (℃) - Closed Cup55Refractive Index (25℃)1.3960-1.3970Applications:1. Application of personal care products (as the basic liquid of personal care products, it has excellent spreading, lubricity and special volatile properties): it can be used for anti sweat and antiperspirant, deodorant, skin cream, lotion, bath oil, tanning and shaving products, cosmetics, nail polish, etc. In hair spray, drying time is faster.In cleaning products, it can remove dirt without leaving oil residue or tingling sensation.2. Industrial application: It is an important intermediate in the silicone industry, mainly used for ring-opening polymerization to form silicone oil, silicone rubber, silicone resin, etc. These polymers are further processed into products widely used in various fields such as construction, electronics, textiles, automotive, personal care, food, mechanical processing, etc., with a small amount of direct application.It can also be directly used as a rubber filler treatment agent.3. This product can be used alone or mixed with other liquid cosmetic ingredients;it has good compatibility with absolute ethanol and other cosmetic solvents;when mixed with cyclic silicone oil, the difference in volatility can adjust the residual time of the silicone oil on the skin;this product has low thermal evaporation energy, and compared to other volatile carriers, it does not cause cold feeling on the skin during use.4. For other uses, the dosage varies from a few PPM to 100% depending on the specific application object and application environment.Storage And Transportation:1. The temperature of octamethylcyclotetrasiloxane storage sites should be between 20°C and 40°C, and insulation and antifreeze work should be done when the temperature is below 17°C.Under the conditions of packaging, transportation, and storage in accordance with standard GB/T 20435-2006.2. During transportation, octamethylcyclotetrasiloxane should be protected against fire, rain, moisture, sun exposure, and the mixing of impurities such as acids and alkalis.3. The shelf life is 6 months.Re-inspection is available after the expiration date, and if the inspection results meet the requirements, it can still be used.PackagingThis product is packaged in 200L iron drums or 1000L IBC drumsZhumao New MaterialsZhumao New Materials, formerly known as Zhumao Organosilicon, is located in Dongguan, China, a well-developed international manufacturing city.Since its inception, the company has long focused on the research, production, and sales of silicone raw materials and their derivatives.It has a research and development center, a marketing center, and three production bases.With a high emphasis on R&D innovation, product quality and talent cultivation, and long-term investment, after nearly 15 years of rapid development, it has quickly become one of the world's leading suppliers of silicone materials, with more than 80% of its products exported and sales covering more than 100 countries around the world.Our experienced staff is committed to strict quality control and thoughtful customer service, and are always available to discuss your requirements and ensure customer satisfaction.We also welcome OEM and ODM orders.Whether you choose current products from our product catalog or seek engineering assistance for your application, you can contact our customer service center to understand your purchasing requirements.Team StyleTravelingBirthday party for employeesDomestic sales teamManagement TeamForeign trade sales teamCustomer VisitsInspection and ShipmentFAQQ1: Are you a trading company or a manufacturer?A: We are a silicone manufacturer with 20+ years' expertise.
