Silicone materials have become an essential part of modern cosmetic formulations. From skincare and makeup to sun care and hair care, silicone oils play a critical role in improving texture, stability, and overall sensory performance. Compared with traditional oils, cosmetic-grade silicones offer excellent design flexibility, stable performance, and a wide range of sensory effects.
Based on structure and functionality, silicone oils used in cosmetics can be broadly classified into the following categories.
Volatile silicone oils, such as cyclic silicones and low-molecular-weight linear silicones, are widely used in cosmetic formulations. Their key characteristic is rapid evaporation after application, leaving little to no oily residue on the skin or hair.
They are commonly used to:
Improve spreadability and slip
Provide a light, dry, and non-greasy skin feel
Act as carriers for active ingredients
In foundations, primers, sunscreens, and color cosmetics, volatile silicones help create smooth application and even film formation before evaporation.
Non-volatile silicone oils mainly include polydimethylsiloxane and various modified silicones. Unlike volatile silicones, they remain on the skin or hair surface and form a lubricating, protective layer.
Their main functions include:
Reducing friction and improving softness
Delivering long-lasting smoothness
Enhancing shine and manageability in hair care
Functional modification with amino, polyether, or alkyl groups allows these silicones to provide targeted performance such as conditioning, hydrophilicity, or improved adhesion.
Silicone elastomers are crosslinked silicone materials that often appear as gels or soft powders. They are highly valued for their unique sensory and visual effects.
Key benefits include:
Soft-focus and wrinkle-blurring effects
Oil absorption without dryness
Improved skin surface smoothness
As a result, silicone elastomers are widely used in primers, foundations, oil-control products, and high-end makeup formulations.
Silicone resins are highly crosslinked materials, typically with MQ or MT structures. Their primary function in cosmetics is film formation and adhesion.
They are used to:
Improve long-lasting wear
Enhance water and sweat resistance
Increase film integrity and gloss
Silicone resins are essential components in lipsticks, mascaras, and sunscreens where durability and performance are critical.
Silicone emulsifiers are modified silicones with both hydrophilic and lipophilic groups, enabling the formation of stable emulsions, especially water-in-silicone (W/Si) or silicone-in-water (Si/W) systems.
Their advantages include:
Lightweight and fresh sensory profiles
Improved stability in complex formulations
Better compatibility with high-SPF systems
They are widely used in BB creams, cushions, and modern sunscreen formulations.
Silicone emulsions consist of silicone oils or elastomers dispersed in water as fine particles. They are easy to use and suitable for water-based formulations.
Main advantages include:
Easy incorporation into aqueous systems
Reduced greasiness with good conditioning effects
Cost-effective and formulation-friendly
Silicone emulsions are commonly found in skincare lotions, shampoos, and conditioners.
From volatile silicones and elastomers to resins and emulsifiers, cosmetic silicone oils form a highly versatile and customizable material system. They play a crucial role in determining product texture, stability, and consumer experience. As cosmetic formulations continue to evolve toward higher performance and better sensory appeal, silicone materials will remain a core technology driving innovation in the cosmetics industry.
