Products Description: What are Cyclomethicones? Cyclomethicones are silicones that possess a cyclical structure rather than the linear structures of dimethyl silicones. Low heat of vaporization and the ability to select a desired vapor pressure has led their use in cosmetic formulations as base fluids and carrying agents.

Cyclomethicones evaporate quickly and are miscible with a wide array of cosmetic oils, silicone oils, waxes, esters and hydrocarbons. They are excellent carrying agents for both cosmetic and industrial applications.

Cosmetic Applications include: body sprays, room sprays, antiperspirants, deodorants, hair sprays, cleansing creams, skin creams, lotions and stick products, bath oils, suntan and shaving product, make-up and nail polishes.

Cyclomethicones are being more widely accepted for industrial applications due to their exemption from Federal VOC regulations including California VOC (CARB) and OTC regulations. Due to their varying rates of evaporation and solvency power, they are excellent replacements for non-VOC petroleum-based solvents. D5 is an effective solvent for dry cleaning application that will not degrade fabrics or make colors run.

Clearco Volatile Silicones have excellent low temperature stability and unique volatility characteristics. They are used in a variety of personal care products.

Cyclo-2244 Cyclomethicone (D4) Fluid

Chemical Name: Octamethylcyclotetrasiloxane

INCI Name: Cyclotetrasiloxane

CAS No:: 556-67-2

Product Equivalent: Dow Corning® 244 Fluid & GE SF1173

Use: Clearco Cyclo-2244 (D4) Cyclomethicone is a volatile polydimethylcyclosiloxane that is composed mainly of octamethylcyclotetrasiloxane (CAS#556-67-2). The product is clear, tasteless, essentially odorless, non-greasy and non-stinging.

Due to their volatility (varying rates of evaporation), low surface tensions (high spreadability), and non-greasy feel, Cyclomethicones are used as base fluids, carrying agents and wetting agents in a wide range of personal care products. Cosmetic applications include: room sprays, body sprays, antiperspirants, skin creams, skin lotions, suntan lotions, bath oils, hair care products etc. see also Cosmetic Grade Silicones

Cyclomethicone Fluids are exempt from Federal VOC regulations, including California VOC Regulations (CARB) and OTC. They do not contribute to ozone-depletion and global warming, and are being widely accepted as replacements for Non-VOC compliant petroleum-based solvents. As carrying agents, Cyclo-2244 and Cyclo-2245 have comparable evaporation rates to naptha solvents, odorless mineral spirits (OMS) as well as some of the isoparaffinic solvents. They are compatible with most substates, including metals and plastics.

Properties:

  • Clear, colorless, odorless fluid
  • Cosmetic grade…excellent for base fluids in cosmetic formulations
  • Volatile carrier (100% evaporation at room temperature)..leaves no residue
  • Low heat of vaporization..non-stinging and will not cool the skin when it evaporates
  • Excellent lubricity before evaporation
  • Low surface tension fluids (high spreadability)
  • Easy Rubout
  • Exempt from Federal VOC regulations (including CARB and OTC)…excellent replacement for petroleum based solvents that are not VOC Compliant
  • Miscible with virtually all polydimethylsiloxane fluids and most petroleum based fluids
  • Soluble in most anhydrous alcohols, waxes, oils (except castor), hydrocarbon oils, esters and silicone fluid.
  • Insoluble in water

Cyclomethicone Fluids are exempt from Federal VOC regulations (including CARB and OTC) and will not contribute to ozone-depletion and global warming. They are being widely accepted as replacements for non-VOC complaint petroleum-bases solvents as both carrying agents as well as for cleaning solvents. Cyclo-2245 is especially effective for applications where low to medium solvency power is desireable. As carrying agents, Cyclo-2244 and Cyclo-2245 have comparable evaporation rates to naptha solvents, odorless mineral spirits (OMS) as well as some of the isoparaffinic solvents. They are compatible with most substates, including metals and plastics.

In addition, D5 Cyclomethicone is being used as a Federal VOC Exempt cleaning agent in dry cleaning applications. It serves to act as a carrying agent for the detergent and will not degrade the fabric or colors of the linens and clothing like other stronger solvents.

Unlike D4 Cyclomethicone (Cyclo-2244), Cyclo-2245 (D5) has a much higher pour point and does not present the freezing concerns that D4 presents.
