Texture
Structure Solanace starch provides formulations with a light, creamy texture, when compared to competitive products.

Stability in Emulsion Systems
Study shows simple cream base pH 4.5 with Structure Solanace starch is the most stable after four weeks under 50°C.

Broad pH range
Structure Solanace starch can be used over a broad pH range. The recommended range is from pH 3.5 to pH 11. It allows the formulation of low pH emulsions containing alpha hydroxy acid (AHA) or dihydroxyacetone (DHA) that exhibit exceptional skin feel, and excellent pH and viscosity stability.

Stability in Emulsion Systems
One of the important properties of the Structure Solanace starch is its effect on emulsion stability. The starch functions to reduce the particle size of an emulsion and increase the stability of a formulation. Figure 4 shows the particle size of a TEA/Stearate emulsion evaluated by micrOscopy analysis. With no starch, the formula exhibits a large particle size, about 50 microns, and poor shelr stability. AS the amount of starch Is increased, the particle size of the emulsion decreases and the formulation stability increases. Figure 5 shows the same emulsion containing 2% Structure Solanace starch. The particle size is <<10 microns, but more importantly the formula exhibits excellent stability under ambient and accelerated aging condi- tions of the starch.
