Ease of use - Because Structure ZEA starch is an agglomerated, pre- gelatinized starch, it will dissolve in cold water almost instantly allowing for flexibility in manufacturing and formulation. The mixing of powdered dyes and bleaches with aqueous components is also made much easier for the end user. One can observe the effects of agglomeration (see below) by measuring the dissolution time the of Structure ZEA starch against a non-agglomerated version of the same modified waxy maize starch base.
Starch Dissolution time (sec)
Structure ZEA starch 173 Non-agglomerated Structure ZEA starch 606 Rheology - Structure® Zea starch is extremely shear-thinning, with rapid viscosity recovery. This is an ideal property for hair and skin treatment products where good workability is desired, yet the formulation must set up instantly when shear is removed.Graph below shows a hysteresis loop of a 5% Structure® Zea starch solution. The near overlap of the increasing and decreasing shear sweeps demonstrates the pseudoplastic nature of this rheology modifier. A gap between the two curves would have indicated a longer viscosity recovery time, leaving a formulation prone to dripping when shear is removed.
