SoBind™ Harmony soy polymers

Raising the performance bar for naturally derived ingredients

At DuPont, we see a multifunctional, renewable and sustainable ingredient as a way to make personal care products safer and better for the environment

DuPont Soy Polymers is the leading global supplier of soy-based specialty polymers for various applications including Personal Care.  SoBind™ Harmony soy polymers are derived from soybeans. Soybeans are a biodegradable, renewable and sustainable resource. 

DuPont Soy Polymers invented a unique Structural Peptide Architecture™ manufacturing process that allows the highly compact protein molecule structure to unfold, exposing active amino acids chains for interaction with other molecules in the formulation.

Such interaction allows “bonding” of side chains of the protein to the polar species such as oils, fragrances and pigments. Better bonding between ingredients enhances their efficiency, prolongs the desired functionality and stabilizes formulation. Our molecule is not only functional, but is also of natural origin, having strong sustainability profile.

SoBind™ Harmony: multiple benefits for the formulator 

Pigment Dispersion: SoBind™ has a strong affinity for pigments – it places them in a matrix, creating a structured film. Soy polymers help wet, disperse and stabilize pigments such as metal oxides, zinc and titanium dioxides in sunscreens and color cosmetics

Stabilization & Emulsification Properties: soy polymers particles can reduce surface tension & stabilize oil in water emulsions due to their amphophyllic behavior.  Some amino acids present in the structure of soy polymer have the chelating ability , which helps to stabilize the formulation. 

Rheology Modification: These soy polymers are colloidal suspensions, and build viscosity by hydrating or swelling. They also provide texture and sensory enhancements to formulations.  

Cost benefits: due to their multifunctional abilities, soy polymers can provide numerous cost saving opportunities. Usage of pigments, fragrances, emulsifiers and other ingredients can be reduced .


SoBind™ Harmony: multiple benefits for the consumer
  

SoBind™ Harmony can be applied in various hair, skin or color cosmetics applications. The end user benefits include, but are not limited to sensory benefits, unique textures, natural conditioning effect, color protection & expression , skin appearance enhancements.
