Polymers for Rheology and Conditioning in Hair and Skin
Posted: December 19, 2011
DKSH’s Performance Materials business unit has collaborated with a polymer manufacturer to launch two polymer lines to its Luna range of products. Luna-mer, is a line of rheology modifiers while Luna-care is a range of conditioning polymers can be used as standard materials or can be individually customized according to each formulator’s need.
Luna-mer is a line of pre-neutralized rheological modifiers and emulsifying-thickening polymers used in a wide variety of personal care applications. They can be added at any time in processing under hot or cold temeratures under very moderate shear. The polymers offer thickening, suspending (due to high yield value), stabilizing and emulsifying (oil droplets are held in the hydrated polymer network) properties.
The polymers are offered in four versions: liquid thickener (LT ), a ready-to-use liquid (Luna-mer 50 LT (INCI: Polyacrylamide (and) C13-14 Isoparaffin (and) Laureth-7); concentrated liquid thickener (CLT), a concentrated (57% polymer), ready-to-use liquid (Luna-mer 10 CLT (INCI: Sodium Polyacrylate (and) Hydrogenated Polydecene (and) Trideceth-6), Luna-mer 20 CLT (INCI: Acrylamide/Sodium Acrylate Copolymer (and) Mineral Oil (and) Trideceth-6), Luna-mer 40 CLT (INCI: Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer (and) Mineral Oil (and) Trideceth-6), Luna-mer 12 CLT (INCI: Sodium Polyacrylate (and) Mineral Oil (and) Trideceth-6), Luna-mer 37 CLT (INCI: Polyquaternium-37 (and) Mineral Oil (and) Trideceth-6) and Luna-mer 37 CLT G (INCI: Polyquaternium-37 (and) Propylene Glycol Dicaprate/Dicaprylate (and) Trideceth-6); thickener powder (TP), a 100% active polymer powder (Luna-mer 10 TP (INCI: Sodium Polyacrylate), Luna-mer 40 TP (INCI: Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer) and Luna-mer 37 TP (INCI: Polyquaternium-37)); and washed powder (WP), a transparent gel formulation (Luna-mer 10 WP (INCI: Sodium Polyacrylate) and Luna-mer 37 WP (INCI: Polyquaternium-37).
The rheology modifiers can be used to formulate highly stable o/w emulsion regardless of the oil type and the HLB value, and in many cases in a wide range of pH values. Emulsions can be made at RT with low shear process. The line imparts a non-greasy and non-sticky after feel. Their particular rheology profile aids in spreading high viscous products. The line is recommended at 0.2-4.0% in skin care and hair care products.
