Structure XL
Hydroxylpropyl Starch Phosphate Ester (Proposed)
STRUCTURE XL is a starch-based rheology modifier that provides excellent stabilisation in emulsion products. This starch, delivered as a powder, is a new concept to simply create and process elegant and stable personal care emulsions. The ease of use and immediate dispersability in cold water make it ideal for use in continuous manufacturing processes. In any type of emulsion for the Personal Care market, STRUCTURE XL can aid in emulsion stabilization, aesthetics enhancement and viscosity build. An emulsion containing STRUCTURE XL will have outstanding stability over a broad temperature range (-30'C up to 50'C). It also brings body to the formulation and a conditioning after feel. STRUCTURE XL is readily cold water dispersible so that no pre-mixes are needed. STRUCTURE XL can be added to the oil phase or at the end of a production, so a ¡°one pot process¡± is possible, leading to major savings in
production costs. Emulsions made with STRUCTURE XL do not require homogenization. Because of its nonionic character and broad compatibility, STRUCTURE XL provides the formulator with the flexibility to formulate over a wide pH range with high amounts of mono- and divalent salts (up to 20%) and a large variety of raw materials.
* Features:
-Cold water-swellable: Outstanding dispersibility in cold water improved efficiencies can be achieved in manufacturing and formulation development.
-Nonionic: Compatibility with other ingredients offers formulation flexibility. Can be used with a wide range of other raw materials like oils, emollients, cationic as well as silicones, UV filters, vitamins, botanical extracts, alpha and beta hydroxy acids, dihydroxy acetone, mono-and divalent salts, fragrances and dyes.
-Shear Thinning: Extremely shear thinning, with rapid viscosity recovery, suitable for emulsion in spray or pump delivery.
-Modified corn starch:
Naturally-derived
Biodegradable
Emulsion stabilizer at any temperature. Simplifies the emulsion formulation procedure.
Aesthetic enhancer bringing conditioning after-feel to emulsions.
-Large particle size: Very low dusting compared to typical powder ingredients.
-Salt tolerant: Stable in the presence of high electrolyte levels (20 %), mono- and divalent salts
-pH stability: Useful in emulsion systems from pH 3 - 9.
Form: Free-flowing coarse powder
Color: White to off-white
Moisture: 12 % max.
pH (10% solution): 4.5-7.5
