“…With the increase in molecular weights of polymers, interactions were also increased to enhance deposition of silicone [55]. After that, Faucher, Hannah and Goddard [56][57][58] reported the application of cellulosic polymer called quaternized hydroxy ethyl cellulose (polymer-JR) and Woodard [59] employed polyethyleneimine (PEI) to improve silicone deposition on hair. The polymers with different molecular weights were studied.…”

Synopsis Silicone oils have wide range of applications in personal care products due to their unique properties of high lubricity, non‐toxicity, excessive spreading and film formation. They are usually employed in the form of emulsions due to their inert nature. Until now, different conventional emulsification techniques have been developed and applied to prepare silicone oil emulsions. The size and uniformity of emulsions showed important influence on stability of droplets, which further affect the application performance. Therefore, various strategies were developed to improve the stability as well as application performance of silicone oil emulsions. In this review, we highlight different factors influencing the stability of silicone oil emulsions and explain various strategies to overcome the stability problems. In addition, the silicone deposition on the surface of hair substrates and different approaches to increase their deposition are also discussed in detail.

“…The polymer JR study involved bleached hair. These data suggest that penetration is limited to about 10% of the hair after 7 days and about an order of magnitude less in unaltered hair [25]. Sorption of a higher-molecular-weight JR polymer (average molecular weight of 600,000) by bleached hair is similar to the smaller polymer by unaltered hair.…”

“…Faucher et al [25] demonstrated that desorption of a polymeric cationic cellulose (polymer JR) (see Table 8.2) from hair is slower than would be expected from a simple diffusional release predicted by the square root of time law [26]. These scientists suggested that desorption of a polymer occurs only after all sites of attachment are broken.…”

“…Charge density is the residue molecular weight per unit of positive charge. This type of polymer has been studied in three different molecular weight versions -250,000, 400,000, and 600,000 -in several excellent publications by Faucher, Goddard, and Hannah [23,25,[31][32][33]. The chemical structure for polymer JR in Table 8.2 approximates the structure of this polymer and is based on information in the CTFA cosmetic ingredient dictionary [34] and the charge density value of approximately 670 [33].…”

Polymers have become increasingly important components of cosmetics over the past few decades. The original uses of polymers in hair care were as fixative agents and viscosity controlling additives; however, new polymers today are also used for hair conditioning and for the development of new style control products. Polymer substantivity to hair fibers increases with molecular size, with an increasing number of polar group attachments and especially with an increasing number of cationic groups for attachment to the negatively charged surface of hair fibers. From an anionic shampoo medium the cationic charge on polymers is neutralized and the adsorbing species is essentially a neutral or negatively charged species. The most successful silicone conditioning polymers for hair care have been used in both shampoo and conditioner compositions. Dimethicones in shampoos condition undamaged or lightly damaged hair better than they condition highly damaged, bleached hair or even tip ends because neutral hydrophobic conditioning agents adsorb more readily to an undamaged hydrophobic surface than to a damaged highly polar hair surface. New block co-polymers and a fairly large number of new cationic polymers have been introduced into hair care recently, while fractal polymers (highly irregular shapes) and nanoparticles have been developed and are receiving attention for potential use in hair care.

“…Coacervate can effectively deposit onto the hair surface, providing multiple benefits to hair [10][11][12][13][14][15]. Most conditioning shampoos depend on deposition of polymer-surfactant coacervate to confer good wet combing and manageability [16,17].…”

The purpose of this study was to examine the correlation between physical properties of dried coacervate films and dry feel for shampoo composition. Simple shampoo compositions were made of two different cationic charge density polymers in the same surfactant compositions. The simple shampoo compositions were diluted with distilled water to make coacervate. Formed coacervate was collected by centrifuge (3,000 rpm, 30 min). Coacervate was coated on the glass plates and dried in drying oven (for 1 h, 50 ℃) to make the thin film. We carried out an experiment on measurement of contact angle, moisture loss ratio and SEM image analysis of the dried coacervate film. Dry feelings of the shampoos were evaluated by panel using hair tresses. Results show that the properties of dried coacervate films affect the dry feel of the after shampooing.
