Silsesquioxanes in the Cosmetics Industry—Applications and Perspectives

Abstract

The rising demand for innovative and sophisticated personal care products is a driving factor for manufacturers to obtain new formulations that will fulfill the customers’ preferences. In recent years, silsesquioxanes have attracted the attention of the cosmetics industry. These compounds have been proposed to be used in novel cosmetic formulations as emollient, dispersant, and viscosity modifiers. Therefore, this publication aims to review the main important aspects of polyhedral oligosilsesquioxanes as ingredients of personal care formulations, taking into consideration different types of products. The methods of obtaining these compounds were also presented. Additionally, the detailed analysis of patents dedicated to the application of silsesquioxanes in cosmetic formulations was also performed.

Synthesis of Vinyl-Containing Polydimethylsiloxane in An Active Medium

“…Polysiloxanes are extensively applied in many fields, including the cosmetic industry, electronics, biomedicine, artificial muscles, etc. [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Such a diversity of applications is owing to the unique properties of polysiloxanes: a wide range of working temperatures, weather resistance, inertness, hydrophobicity, chemical stability, low dielectric permittivity, etc.…”

Preparation and Utilization of a Comb‐Like Polycarboxylate Dispersant for Organic Pigment

“…Dispersants can uniformly disperse inorganic or organic particles in a dispersion medium and stabilize the suspension by hindering the agglomeration of particles. Dispersants have been broadly used as a common type of surfactant in multiple applications, including but not limited to pigments, [1] inks, [2] cosmetics, [3] ceramics, [4] medicine, [5] and concrete [6] . The quality and performance of the product in the abovementioned fields are directly affected by the application of the dispersant [7–10] …”

The Effect of Various Polyhedral Oligomeric Silsesquioxanes on Viscoelastic, Thermal Properties and Crystallization of Poly(ε-caprolactone) Nanocomposites

“…Various POSS particles have been incorporated into thermoplastic polyolefins [ 28 , 29 ], polylactide [ 30 ], elastomers [ 31 , 32 ], elastomeric blends [ 33 ], epoxy resins [ 34 ], polysiloxane foams [ 35 ], leading to the enhancement of various properties. Polyhedral oligomeric silsesquoixane particles are commercially applied in the cosmetics industry [ 36 ]. The low cytotoxicity of POSS allows their application in medicine [ 37 , 38 ].…”
