Dow Corning’s New Approach Citycare Helps Protect Skin from Particulate Air Pollution

« Air pollution levels in the world’s fast-growing urban centers are rising – as are consumer concerns about the damaging and aging effects pollution can have on the skin.


Consumers are increasingly concerned about the damaging and aging effects particulate air pollution can have on their skin. They want – and need – effective skin-protection solutions. Dow Corning develops an innovative approach that mirrors the natural pollution-protection properties of the lotus leaf.

Introducing a Nature-inspired Approach to Skin Protection

The leaves of the lotus plant (Nelumbo nucifera) naturally remain clean and free from particulate matter.
This is due to specific surface properties (low surface energy plus a microroughened structure) that combine to prevent both water and solid particles from attaching strongly to the leaf.

With their unique ability to mirror these properties, silicone film-formers from Dow Corning can help create multifunctional cosmetic, skin care and sun care formulations that:

• Provide a barrier effect against particulate air pollution
• Help reduce the detrimental impact of pollutants on skin
• Are smooth, comfortable and flexible to wear

For real Beauty with impact, silicone innovations from Dow Corning offer new levels of performance – tested and validated.
Dow Corning has investigated the potential of a variety of Dow Corning® silicone film-formers in three different formulation types – water-in-oil, hydrogel and oil-in-water.

The conclusion?
Reduced particulate-adhesion properties can be achieved in major cosmetic formulation systems when the appropriate silicone film-forming technology is used.

New formulations include:

• Oil-in-water cream for pollution protection
• Water-in-oil skin cream for pollution protection
• Hydrogel for pollution protection

Formulating for Citycare

Building effective Citycare anti-pollution skin care formulations relies on the interaction between a specific silicone technology and the non-volatile fraction of the formulation.
With the right silicone technology for your system type, it is possible to create a protective film with a level of microroughness that reduces the tendency of particulate matter to adhere to it. »
