New opportunities to improve hair conditioning are emerging due to the increased frequency of hair damage resulting from various grooming techniques, demographic changes in age and ethnicity and affluence in both developed and emerging markets. Silicones are commonly used in conditioning shampoos to improve wet and dry combing, hair feel, shine and manageability. Cationic conditioning polymers are used in combination with silicone in high performance formulations to enhance hair conditioning. One of the primary functions of cationic conditioning polymers is to increase the amount of silicone deposited on hair during the shampoo cycle via the formation of coacervates. Coacervates formed during shampoo dilution can effectively deposit silicone and otheringredients onto hair fibers.

Carbopol® Aqua SF-2 Polymer
Laureth Sulfate (SLES) and Cocamidopropyl Betaine (CAPB) has been studied via a design of experiments (DOE). Statistical models have been established to predict performance for a given formula or to offer a starting formula to achieve desired performance. A comprehensive understanding of the formulation behavior has been developed. Increasing polymer concentration raises formulation clarity, viscosity and yield value and improves flow texture. Adding more surfactant boosts clarity, viscosity and yield value, but does not necessarily improve flow texture. Raising the level of the secondary surfactant, CAPB at a fixed total surfactant concentration, enhances viscosity and yield value, but reduces formulation clarity and worsens the flow texture.

N-Octyl-D-gluconamide (C8-DGlu) is known to form hydrogels; however, as is the case with many low
molecular weight gelators, C8-DGlu crystallizes from the gel state within a few hours. Thus, in order for
such gelators to find uses, e.g. as viscosity modifiers, potential methods to increase their lifetime
stability by significantly delaying or altogether preventing the onset of the crystallization need to be
investigated. We show herein the effect of various nonionic surfactants, primarily those from the
Laureth-n series, on the lifetime stability and mechanical properties of C8-DGlu gels. In contrast to
previous literature work using anionic surfactants, the use of nonionic surfactants allows gels to be
formed in a much wider composition range of the two components (gelator and surfactant) yielding the
ability to systematically tailor the mechanical properties of the gels across several orders of magnitude.

From Mumbai to Mexico City, from Shanghai to Sao Paulo, skin whitening, in all application forms is a significant trend. In fact, according to Euromonitor, 2010, the global skin lightening market is predicted to reach $10 billion by 2015 driven by new market development in the west and sustained growth in Asia Pacific. Fairer skin in these cultures equates to beauty, power and success. There are many options for formulators to deliver skin whitening systems that delight consumers, and encourage repeat use. However, there are also significant challenges to stabilizing the actives and achieving the right product aesthetics to reach market sensory targets. The purpose of this paper is to share with formulators some concrete and simplified information that will help them achieve their formulating goals.

Formulation composition has a dramatic infl uence on coacervate formation in conditioning shampoo. The purpose of this study is to correlate the amount of coacervate formation of novel cationic cassia polymers to the corresponding conditioning profi les on European brown hair using silicone deposition, cationic polymer deposition and sensory evaluation. A design of experiments was conducted by varying the levels of three surfactants (sodium lauryl ether sulfate, sodium lauryl sulfate, and cocamidopropyl betaine) in formulations containing cationic cassia polymers of different cationic charge density (1.7 and 3.0m Eq/g). The results show formulation composition dramatically affects physical properties, coacervation, silicone deposition, cationic polymer deposition and hair sensory attributes. Particularly, three parameters are of importance in determining silicone deposition: polymer charge, surfactant (micelle) charge and total amount of surfactant (micelle aspect ratio). Both sensory panel testing and silicone deposition results can be predicted with a high confidence level using statistical models that incorporate these parameters.

Cassia gum is a natural, vegetable-based carbohydrate based on mannose and galactose sugars. A member of the galactomannan family of polysaccharides, Cassia grows wild in tropical zones around the world, such as India. It has been used for more than a thousand years in Ayurvedic and Chinese medicine to treat skin ailments, indigestion and pain, and is used today as a gelling agent in pet and human food applications.
Polysaccharide derivatives have a long history of use in personal care applications as thickeners, conditioning polymers, deposition aids and film formers. Cationic derivatives of guar gum, another galactomannan, have been successfully used in conditioning shampoos in combination with silicones to impart improved combing and sensory properties. Compared to other polysaccharide derivatives, cationic derivatives of cassia gum offer distinctly different levels of performance and sensory properties in hair care formulations.

Novethix™ L-10 Polymer
The associative behavior of a new Hyper-HASE polyelectrolyte (INCI: Acrylates/Beheneth-25 Methacrylate Copolymer) in surfactant solutions was studied. Viscosity data indicate that the polymer, which contains a high level of hydrophobic cilia groups, exhibits a unique combination of polyelectrolyte and associative properties. The polymer forms hydrophobic junctions with the surfactant micelles, giving rise to a diversity of polymer-surfactant mesophases. The data indicate that salts such as NaCl or NH4Cl affect the overall structure of the mesophases resulting in 2 to 4 orders of magnitude increase in viscosity with respect to the viscosity of the neat surfactant solutions. Understanding the interplay between the polymer and surfactants is important since the polymer may affect the rheology and performance of personal care cleansing formulations.

Novethix™ L-10 Polymer
The association of a new Hyper-HASE polyelectrolyte (INCI: Acrylates/Beheneth-25 Methacrylate Copolymer) in water and in aqueous surfactant solutions has been studied. Viscosity data indicates that the Hyper-HASE polyelectrolyte, which contains a relatively high concentration of hydrophobic cilia groups in its backbone, exhibits a unique combination of typical polyelectrolyte and associative properties due to its charged backbone and hydrophobic cilia groups. At pH 7 the polymer exhibits an unusual viscosity response which is the result of the balance of electrostatic repulsive forces and hydrophobic attractive forces. In surfactant solution containing a nonionic, low HLB surfactant, the Hyper-HASE polyelectrolyte exhibits a transient associative behavior which is strongly dependent on surfactant concentration under certain conditions of shear. In particular for the Hyper-HASE association with Laureth-2, steady state viscosity data at low, mid and high shear rate indicates that the polymer forms stable hydrophobic junctions with the surfactant micelles giving rise to the development of an extended polymer-surfactant network.

Fixate™ Superhold Polymer
A novel approach is taken to understand the mechanical performance of fixative-treated hair tresses. Polymer composite principles are applied to explain the performance. Examples are given for polyacrylate-2 crosspolymer that show that the choice of neutralizer affects the film properties of anionic acrylic polymers by plasticization or by hardening through ionic (physical) crosslinking. The effect of these changes in the polymer film on the composite properties was determined by mechanical stiffness and high-humidity curl retention testing. It is shown that both adhesion to the hair and polymer cohesion are important in determining fixative polymer performance. The implications of the results for the formulation of fixative systems are discussed.

Carbopol® Aqua CC Polymer
Formulators seeking to modify the rheology of their product compositions at low pH, especially emulsions, are limited to choosing between nonionic thickeners (such as nonionic surfactants) and cationic thickeners. the former are uncharged and thus are assumed to be less reactive to cationic components than anionic thickeners, but they tend to inactivate preservatives and may promote microbial growth. To meet the growing demand for thickeners suitable for low pH formulations, we introduce Carbopol® Aqua CC polymer to our Carbopol® polymer family.

Carbopol® Aqua CC Polymer
In many cases, high performance formulations are designed to deliver enhanced conditioning for hair or skin through the use of cationic ingredients, the delivery of actives, or the use of ingredients offering anti-aging benefits at low pH levels. Traditionally, these challenging formulations have limited the choice of rheology modifiers which can be used. Typical anionic thickeners may not be well suited in a low pH or cationic containing environment, and non-ionic options may provide undesirable aesthetics. Now, Carbopol® Aqua CC polymer, the newest member of the Carbopol® polymer family, overcomes these limitations and creates new formulating possibilities. This premier cationic compatible liquid rheology modifier was specially designed for use in low pH personal care applications where low to medium viscosity is desirable. This patent-pending new polymer offers high clarity, a smooth feel and excellent suspension capabilities, properties for which Carbopol® polymers have long been the preferred choice in other applications.

Aesthetic properties are some of the most important features of personal care products. While any shampoo can cleanse the hair, those that look attractive at the point of sale, and are more pleasant to use, are the ones that ultimately win market share. Thus, the need to enhance the
sensory experience, beyond focusing solely on product functionality, is a critical challenge facing formulators. This is why, for example, surfactants are not used solely for cleansing, but also to deliver richer, more billowy lather and to minimize the risk of irritation. Similarly, rheology control agents are not used solely for thickening. Today’s rheology modifiers must offer not only the functional aspects of thickening, suspension and stabilization, but must also provide enhanced appearance to the finished product; superior flow and pour properties; a smooth, light, cushiony feel in use and a pleasant after-feel. This article presents three novel technologies designed to exceed expectations for functionality as well as sensory attributes: Acrylates Copolymer, for use in surfactant cleansing systems, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, for use in surfactant-cleansing or aqueous based systems, and Polyacrylate-14, for use primarily in aqueous-based systems.

A fundamental study of the stability of hydrogen peroxide-based gels, thickened using crosslinked polyacrylic acid polymers, will be presented. Recent systematic experiments will demonstrate that excellent long-term stability of such gels can be achieved. The study evaluates different types of crosslinked polyacrylic acid polymers (as well as an associative acrylic polymer), several commercial sources of hydrogen peroxide, hydrogen peroxide concentrations and the effect of pH.
