Cyclomethicone can be used as a volatile carrier and is compatible with a wide range of cosmetic ingredients.

It helps to improve the rubin and spreadability of creams and lotions. Table 1 illustrates the heat of vaporisation for several compounds cyclopentasiloxane takes less energy to evaporate compared to water and ethanol.Ĭyclomethicone with low heat of vaporisation and low viscosity imparts a transient, non-greasy and non-cooling effect on skin. The term of cyclomethicone refers to a series of cyclic silicone compounds (Fig. Volatile silicone fluids consist of cyclic and linear molecules having a viscosity of less than 5 cst. With these unique properties, silicones make an ideal choice for a multitude of personal care applications. This leads to ultra low surface tension values compared to organic polymers. The Si-O (silicon-oxygen) bond and Si-C (silicon-carbon) bond allow freedom of rotation, which enables these molecules to adopt the lowest energy configuration at interfaces. Silicone is the term used for materials in which silicon is bonded to oxygen in a linear polymeric matrix.

Often manufacturers and consumers mistakenly believe that silicones are oil-derived petrochemicals, whereas, they are actually synthetic products prepared from sand or quartz, among the most abundant minerals on earth.

Silicon (Si) is the second most abundant element on Earth it chemically bonds to oxygen, as silica, that is SiO2, the natural basis of sand. Silicones are available in numerous formats providing the formulator with endless possibilities to introduce luscious softness and shine to hair care products, luxurious texture to skin preparations with excellent spreading, long-lasting and protecting effects. A unique and multifunctional set of properties combine to ensure silicones stay at the top of the formulator’s toolkit, delivering superior aesthetics and unmatched, cost-effective, sensory benefits. Silicone chemistry is playing an increasingly important role in modern personal care and cosmetic formulations.
