Gransil SIW Technology

The simple (and effective) way to load silicone elastomers into water-based formulations; water-coated GRANSIL SiW ELASTOMER GELS are the new vehicle of choice for creating personal care products. Technically GRANSIL SiW ELASTOMER GELS offer formulators the ideal opportunity for loading high levels of Polysilicone-11 elastomer into water-based gel structures with minimal use of emulsifiers (at levels below 0.5%), and by cold processing methods. Stable formulations achieved with such low levels of emulsifiers also serve as excellent delivery-bases for active ingredients.

The challenges of dispersing standard silicone elastomers in water are well known. Standard silicone elastomers can be very difficult to disperse uniformly in external water phase emulsions or aqueous gels due to their inability to fit into o/w micelles, and general hydrophobic incompatibility with water. Often when processing, excessive levels of surfactants and high shear energy is required to disperse and maintain particles to a stable state. High concentrations of surfactants (which coat particles to maintain a dispersion) unfortunately reduce the elastomer sensory properties by creating tackiness. Surfactants are also more likely to cause skin irritation or some level of barrier disruption. The unique design of versatile GRANSIL SiW ELASTOMER GELS resolves these challenges.

GRANSIL SiW ELASTOMER GELS can be formulated to offer unique sensory benefits with a water-topowder break on application. The outer water phase cools, soothes and hydrates skin on contact, while seconds later silicone elastomer particles release from a gel matrix to fill lines and even complexion with soft powder-like texture. GRANSIL SiW ELASTOMER GELS can also be used to improve sensory aesthetics of existing emulsions with easy post-addition. Grant Industries offers a wide range of gels from high volatility to non-volatile meeting the sensory and regulatory requirements of any formulation project. Applications include skin care, daily wear, color cosmetics, sun care, body care, and hair care.

Highlights of Gransil SiW technology

Challenges of dispersing standard silicone elastomers in water:

  • Silicone elastomers can be very difficult to disperse uniformly in external water phase emulsions or aqueous gels due to their inability to fit into o/w micelles and general hydrophobic incompatibility with water
  • Often excessive levels of surfactants and high shear energy is required to disperse and maintain particles to a stable state
  • High concentrations of surfactants (which coat particles to maintain a dispersion) unfortunately reduce the elastomer sensory properties by creating tackiness. Surfactants are also more likely to cause skin irritation or some level of barrier disruption and TEWL

Objectives for silicone elastomers in water:

  • Offer a highly uniform and concentrated dispersion of elastomer particles in water with minimal use of surfactants
  • Offer a formulation dial to maximize sensory performance
  • Allow the possibility for cold process and energy saving applications
  • Improve material cost and efficiency
    • By increasing sensory performance
    • By reducing cost of emulsifiers in a formulation
    • By reducing cost of high energy/heat manufacturing

Gransil SiW Technology: Formulation Benefits, Energy Savings, Applications and Suggested Uses

Formulation Benefits:

  • Ease of use in formulation and manufacturing scale up
  • Minimal use of emulsifiers offers great bio-compatibility
  • Highly compatible with commonly used rheology modifiers; natural, mineral or synthetic thickeners as well as emulsion stabilizers
  • Totally unique and elegant sensory profile; “wet-to-powder” transition
  • Ideal vehicle for the delivery of active materials
  • Enhances the feel of basic O/W emulsions; add 5-15% to existing emulsions
  • Outer aqueous design (SiW) allows simple addition of silicone elastomers into formulations
  • Cold process/energy cost savings, great stability, easy handling

 

Energy Savings:

  • To reduce overall manufacturing costs, simply combine phase B to A, no heat required

 

Applications and Suggested Uses:

  • Mainly designed for silicone-in-water dispersion systems; 5-70% application dependent
  • Can be used to improve sensory aesthetics of existing emulsions; 5-15% application dependent
  • Skin care, daily wear, color cosmetics, sun care, body care, hair care
