Olefin Graft for Hair Care

  •   Olefin Graft Polymer Technology  

 

Interpolymer's Olefin Graft Polymers Currently Include:  

 

This is a view of a graft polymer showing how the different segments extend along different planes.  Depending on where this interaction occurs, the olefin section will effect the position of the styrene/acrylate portion.  The rate and amount of migration is controlled by the selection of monomers and olefin.

 

Olefin graft polymers were developed by grafting an amorphous functional acrylic polymer section onto a crystalline olefin backbone. The crystalline portion provides barrier, moisture retention, elasticity, and tactile attributes such as lubricity and feel. The amorphous graft polymer portion slows down the migration of the low density olefin which ascends to the surface during drying resulting in a more uniform film formation. The result is better and more predictable performance attributes such as flexibility, adhesion and substantitvity (as depicted in the following graph).

 

FORMULATING TIPS USING SYNTRAN POLYMERS

 

 

 

 

 

Syntran olefin graft multi-functional polymers enhance hair care formulations by providing volumizing and texturizing attributes.  They can improve hair strength, luster, comb-out, gloss, and thermal restorative capabilities.  In skin care, they may improve film elasticity and provide moisture barrier protection. 

 

Benefits of Olefin Graft Multi-Functional Enhancing Polymers For Hair Care Formulations

  • High level of texturizing
  • Better hair strength, luster, comb-out
  • Thermal restorative capabilities
  • Excellent "feel"
  • Compatible in relaxer systems
  • Increased gloss
  • Barrier properties
  • Film Elasticity

Curl Retention

  • The swatches were sprayed with a polymer containing formula and curled prior to drying for 12 hours.
  • The swatches were hung vertically and curl retention (droop) was measured initially and then hourly for the next seven hours.
  • Variables such as temperature and relative humidity were controlled  in order to stress test polymer performances.

 

 

Thermal Restyling Results

  • Curl Retention is measured @ the initial and @ 4 hours.
  • The hair is then brushed 5X with a wide toothed comb and CR is again measured.
  • The hair is then restyled with an iron without additional application of fixative.
  • CR is again measured (against original curl) at restyling, and again @ one and two hours.

 

 

 

Evaluation of Hair

 

 

 

 

 

 

 

Olefin graft multi-functional polymers are designed to accentuate hair care formulations.  They can increase color retention when formulated into a variety of products including shampoos, conditioners and reactive dye formulas.  These products act to limit the migration of molecules in and out of the hair shaft, and thereby contribute to vivid initial dye characteristics.

 

Because of the unique combination of acrylic and olefin chains, this polymer can also offer a formulator the opportunity to incorporate some soft hold characteristics to a color enhancing formulation. 

 

Benefits of Olefin Graft Polymers For Improved Color Retention

  • Improved Dye Receptivity--Lower Raw Materials Cost
  • Excellent "Feel"
  • Increased Gloss
  • Styling Potential
  • Barrier Properties
  • Film Elasticity

 

Color Retention Study - Semi-Permanent Dye

  • Swatches, other than control conditioner, are treated with a spray on conditioner containing 3% Olefin Graft polymers (PC 5208 or PC 5205).
  • Swatches washed with color retention shampoo were treated with control conditioner.
  • The swatches were oven dried for one hour at 35° C.
  • The above cycle is repeated 12 times, with measurements taken at 4, 8 and 12 intervals.
  • The hair samples were evaluated for color loss using a spectrophotometer.
