Structure® Xl is a starch-based rheology modifier designed for emulsion stabilization in personal care products. Delivered as a powder, it offers ease of use with immediate cold-water dispersibility, ideal for continuous manufacturing processes. It enhances emulsion stability across a broad temperature range (-30°C to 50°C), builds viscosity, and imparts a conditioning after-feel. Structure® XL can be added to the oil phase or used to adjust batch properties during production. Its nonionic nature and broad compatibility enable formulation flexibility across a wide pH range, accommodating up to 20% mono- and polyvalent salts and various raw materials.

Formulation Guidelines

Because Structure® Xl starch is a specially processed pregelatinized starch, it will disperse in cold water instantly without requiring sifting or premixing. This allows for flexibility in manufacturing and formulation. Within 3 minutes at room temperature, 90 % of the viscosity of an aqueous Structure® Xl starch dispersion is built.

Compatibility with other ingredients - Structure® Xl starch is compatible with salts (mono and divalent), cationic and anionic ingredients, and other ingredients common to personal care emulsions (oils, emollients, silicone, UV filters, AHA, DHA). It can aid in the speed of dissolution of other powder ingredients, and will not contribute to dusting. The Structure® Xl starch can be considered eco-friendly. It is naturally derived and biodegradable. It offers the potential for production by cold process, and thus can significantly reduce energy requirements as well as manufacturing costs. It should not be over extensively homogenized due to potential breakdown of the particles.
