Rheocare HSP-1180 is a polyacrylamidomethylpropane sulfonic acid homopolymer of acrylamidomethyl-propane sulfonic acid. Rheocare HSP-1180 has been designed to provide cosmetic formulations with a high degree of lubricity both during and after use even at low concentrations. In this manner, its effect is two-fold. First, the consumer perceives an elegant, aesthetically pleasing slip during the application, and second, a talc-like residual feel later on. Additionally, Rheocare HSP-1180 will act as an auxiliary-thickening agent particularly in hydro alcoholic systems that are resistant to viscosity build-up. Furthermore, because Rheocare HSP-1180 contains, as part of its molecular structure, sulfonic acid groups, it is soluble in strong acids and strong bases (where it can be effectively neutralized by a host of alkaline cations).

Rheocare HSP-1180 is ideally suited for application in creams and lotions, liquid (i.e. roll-ons) antiperspirants, shaving creams, nail polish removers, liquid and bar soaps, after-bath splash, and other areas where lubricious effects and/or viscosity effects are desired.

Aesthetically pleasing slip during application and has a talc-like residual feel later on. It is soluble in strong acids.

Example of use
RHEOCARE HSP-1180 is a polyacrylamidomethylpropane sulfonic acid homopolymer of
acrylamidomethyl -propane sulfonic acid. RHEOCARE® HSP–1180 has been designed to
provide cosmetic formulations with a high degree of lubricity both during and after use even at low
concentrations. In this manner, its effect is two-fold. First, the consumer perceives an elegant,
aesthetically pleasing slip during application and second, a talc-like residual feel later on.
Additionally, RHEOCARE® HSP–1180 will act as an auxiliary-thickening agent particularly in
hydro alcoholic systems which are resistant to viscosity build-up. Furthermore, because
RHEOCARE® HSP–1180 contains, as part of its molecular structure, sulfonic acid groups, it is
soluble in strong acids and strong bases (where it can be effectively neutralized by a host of
alkaline cations).
RHEOCARE® HSP–1180 is ideally suited for application in creams and lotions, liquid (i.e. rollons)
antiperspirants, shaving creams, nail polish removers, liquid and bar soaps, after-bath
splashes, and other areas where lubricious effects and/or viscosity effects are desired.

Poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) displays interesting properties
that may lead to many potential applications. Such properties arise from the strongly ionizable
sulfonate groups in its chemical structure, its pH-responsiveness and its swelling behavior [1–3]
AMPS-containing polymers have been successfully applied in polyelectrolyte membrane fuel
cells [1], as catalytic membranes for biodiesel production [4] and in medical applications due
to their low toxicity, hydrolytic stability and antimicrobial activity against microorganisms [5,6].
Moreover, they are used in a wide range of industrial products such as cosmetics, coatings and
adhesives, amongst others [7]. Homo- and copolymers of this monomer have been synthesized
straightforwardly by free radical polymerization [8–10]. However, it is well known that it is
nearly impossible to obtain predetermined molecular weights through the conventional radical
mechanism due to chain termination reactions [11]. On the other hand, atom transfer radical
polymerization (ATRP) has emerged as a robust technique for synthesizing well-defined polymers
with predetermined molecular weights, low dispersity and with dierent compositions, topologies
and functionalities [12,13]. A literature review indicates that in the polymerization of PAMPS by
the ATRP technique with copper catalysts, neutralization of the acid groups is required to prevent
protonation of the amino-based ligands, which can lead to the decomposition of the copper/ligand
catalytic system and to avoid subsequent side reactions [14–19]. In many cases, the characteristics of
a quasiliving ATRP have not been observed, despite the use of AMPS in its salt form.
