Hexamethyldisiloxane (HMDSO)

Description

Product code : SC-201,0.65 CST

Chemical name ：Hexamethyldisiloxane

Other name : HMDSO

Equilavent products : Andisil® SF 0.65，BRB DM 0.65

Hexamethyldisiloxane is a volatile fluid with an appreciable vapor pressure at ambient temperature and commonly used as a base fluid in personal care products due to its excellent spreading and unique volatility characteristics. It is clear, tasteless, essentially odorless and non-greasy. Unlike other volatile carriers used in the personal care industry, this volatile silicone fluid does not cool the skin when it evaporates, a consequence of its unusually low heat of vaporization.

Features

Good dielectric properties                                            

• High water repellency                                                      

• High shearability without breakdown                                                

• High compressibility                                             

• High spreadability                                                      

• Low surface tension                                                        

• Low reactivity                                                                

• Low vapor pressure                                                       

• Good heat stability                                                             

• Good leveling and easy rubout                                             

• Essentially odorless                                                     

• Soluble in a wide range of solvents                                            

• Volatile carrier                                                            

• Compatible with a wide range of cosmetic ingredients For personal care: • Soft feel and subtle skin lubricity                                           

• Excellent spreading                                                        

• Leaves no residue or buildup                                                      

• Transient effect                                                        

• Nongreasy feel For industrial applications:                                       

• Little change in physical properties over a wide temperature span – a relatively flat viscosity-temperature slope, and serviceability from -40°C up to 200°C                                                            

• Low surface tension – readily wets clean surfaces to impart water repellency and release characteristics

Physical properties 

Applications

• Personal care products such as hair sprays, cleansing creams, skin creams, lotions, bath oils, suntan products, and nail polishes
