Today’s consumers are increasingly discerning and demanding when it comes to the products they’ll use to create hairstyles that look good, last long and feel great. The development of hair styling products that meet performance and cost requirements is further complicated by the consumers’ desire for products that contain naturally derived or sustainable ingredients.
To meet these requirements, formulators must move beyond the traditional portfolio of synthetic polymers that have long been employed as the hair fixative ingredients in gels, mousses and styling aids. AkzoNobel Personal Care has developed a new hair fixative polymer that features an improved sustainability profile compared to traditional styling polymers, such as PVP (polyvinylpyrrolidone) and VP/VA (vinyl pyrrolidone/vinyl acetate) copolymers. Innovation in natural polymer modification has enabled the development of this new polymer, which can be used to create styling products with a more sustainable and renewable ingredient profile while still maintaining the formulation attributes and performance characteristics desired by the consumer.
Styling Gel Basics
Hair styling gels and related styling products are designed to help create unique styles and hold the style in place. A well-formulated gel will remain flexible when initially applied to the hair but will become stiff as it dries. The primary ingredient that makes a styling gel hold the hair in place is the fixative polymer. These polymers are typically based on synthetic vinyl monomers such as PVP or VP/VA copolymer. They give good hold while remaining sufficiently hydrophilic to be easily washed out of the hair. The other ingredient that is critical in a styling gel is the rheology modifier. There are countless cosmetically-acceptable rheology modifiers or thickening agents that can be used for styling applications. The most common styling gel rheology modifier is carbomer, a synthetic acrylic polymer that is acidic when put into a water solution. When the polymer is neutralized with a base such as triethanolamine, it causes crosslinking within the polymer, which in turn creates the distinctive gel rheology and texture that is popular with today’s consumer.
Other ingredients, including colorants, solubilizers, solvents, emollients, spreading agents, preservatives and conditioning agents, have varying degrees of effect on the overall performance of the styling product. But the fixative polymer and the rheology modifier are the main determinants of the overall attributes of a hair gel.
A common gel format is PVP and carbomer. This gel system, while well known and widely used, is also completely synthetic in nature. As today’s formulators get pressured to develop and introduce products with a more sustainable and renewable profile, the need for alternative gel ingredients has become more pronounced. The introduction of Maltodextrin/VP copolymer* allows the formulator to make cutting-edge styling formulations with a more naturally derived product profile. Gels formulated with Maltodextrin/VP copolymer feature equivalent fixative polymer performance as compared to gels based on market-leading synthetic polymers, thereby allowing the development of more naturally derived gels and styling products without compromise on performance or product aesthetic properties.
Chemistry and Properties
Consumer interest in naturally derived styling products continues to grow, but efficacy remains paramount. Consumers want more natural products that strike the right balance of performance and value. By utilizing the naturally derived oligosaccharide maltodextrin as a starting material, scientists at AkzoNobel Personal Care have created a styling polymer that features a more renewable profile versus traditional PVP or VP/VA copolymers.
This unique polymer is produced via polymerization of n-vinyl pyrrolidone in the presence of maltodextrin. This new hybrid technology has been assigned the INCI name Maltodextrin/VP copolymer. The polymer is nonionic, supplied as a 25% solids solution in water, and contains a globally accepted preservative. The proposed structure of Maltodextrin/VP copolymer is shown in Figure 1.
When incorporated into hair styling formulations, Maltodextrin/VP copolymer provides exceptional clarity and consumer-preferred rheology. These features are typically associated with synthetic fixative polymers, and to date have not been achievable with more naturally derived starting materials. Maltodextrin/VP copolymer contains more than 50% naturally derived content, resulting in an improved sustainability profile compared with traditional synthetic nonionic fixative polymers. Maltodextrin/VP copolymer is the first more sustainable hair fixative polymer in the marketplace to provide excellent clarity, carbomer compatibility and desirable on-hair performance.
Performance Summary
Maltodextrin/VP copolymer provides the benefits that meet today’s formulating needs by offering styling performance similar to that achieved with well-known and widely used polymers such as PVP (having a K value of 30) and VP/VA copolymer. Hair styling gels formulated with Maltodextrin/VP copolymer were compared to PVP (having a K value of 30) and VP/VA copolymer gels. Results show that Maltodextrin/VP copolymer has:
Gel Formulation Properties
Maltodextrin/VP copolymer provides the formulator with a new option to satisfy customer and consumer demands for more natural styling products without any compromise on performance. Maltodextrin/VP copolymer can be used in a wide range of products such as gels, mousses, lotions, creams, pomades, spritzes and other styling aids. Recommended Maltodextrin/VP copolymer use levels range from 4-25% (as supplied) in hair gels, 8-24% (as supplied) in mousses and 4-24% (as supplied) in styling creams and lotions.
Maltodextrin/VP copolymer features excellent gel clarity, stability and aesthetic properties. As shown in Table 1, when gels containing carbomer rheology modifier are neutralized with aminomethylpropanol (AMP) or triethanolamine (TEA), the Maltodextrin/VP copolymer gel shows a slightly higher viscosity (at equal polymer use levels) compared to gels formulated with PVP or VP/VA copolymer.
The Maltodextrin/VP copolymer gels feature very low turbidity and clarity similar to gels based on traditional, synthetic-based polymers. Earlier styling polymers that were more naturally derived were typically cloudy to opaque when incorporated into gel systems. This high turbidity, along with unusual rheological properties, resulted in limited consumer acceptance in styling products.
On-Hair Performance
On-hair performance testing was performed on a simple hair styling gel containing 3% active polymer and 0.5% carbomer. A gel formulated with the Maltodextrin/VP copolymer was compared to a gel containing PVP (having a K value of 30) and also to a gel containing VP/VA copolymer. An eight-person trained panel evaluated for subjective properties of gloss, stiffness, dry comb, flaking, static and dry feel. All testing was done on European virgin brown hair tresses. The results are reported at a 95% confidence level.
As shown in Table 2, the hair gel formulated with Maltodextrin/VP copolymer had superior dry feel compared to the PVP gel-treated hair tress. No detectable differences in on-hair performance properties were seen when comparing hair tresses treated with the Maltodextrin/VP copolymer gel to tresses treated with VP/VA copolymer gel.
Formulators can easily and confidently substitute Maltodextrin/VP copolymer for the commonly used synthetic nonionic polymers at equal active polymer levels. The test results indicate very little difference in on-hair properties between the Maltodextrin/VP copolymer and the synthetic nonionic polymers.
High Humidity Curl Retention
High-humidity curl retention is a well-accepted indicator of the humidity resistance of a product and is used as a gauge for overall hold. In high-humidity curl retention evaluations, virgin brown European hair tresses are treated with the gels, rolled in curlers and allowed to dry in a constant temperature and humidity room. These tresses are then subjected to 21°C, 90% relative humidity conditions and the rate that the curl “falls out” of the tress is measured.
As shown in Figure 2, Maltodextrin/VP copolymer has similar humidity resistance (at the 95% confidence level) to PVP and VP/VA copolymer after two hours.
Compatibility and Uses
Maltodextrin/VP copolymer is supplied as a low-viscosity aqueous solution, making it easy to incorporate into a variety of styling products. It is nonionic and has excellent compatibility with other commonly used personal care ingredients. Maltodextrin/VP copolymer is soluble in water as well as hydroalcoholic solutions, tolerating up to 15% ethanol. In addition, it is compatible with most common gel additives, including, but not limited to, panthenol, silicones, sorbitol, EDTA, GLDA, polyethylene glycols and polypropylene glycols.
Good gel clarity and viscosity are achieved in conjunction with carbomer. Maltodextrin/VP copolymer is also compatible with other rheology modifiers, including ethyl hydroxyethylcellulose, hydroxyethylcellulose, acrylates/steareth-20 itaconate copolymer and acrylates/C10-30 alkyl acrylate crosspolymer. It is compatible with many other nonionic, anionic or cationic polymers, which permits its use where different performance characteristics or product formats may be desired.
Formulation Suggestions
When using Maltodextrin/VP copolymer with carbomer, Maltodextrin/VP should be added to the batch after the carbomer has been neutralized. For optimal clarity in carbomer gels, the formulation pH should be adjusted with the selected base to a pH of 6.0-6.5.
Improved Sustainability
Cradle-to-grave life cycle analysis of hair gels containing different styling polymers was also conducted.The styling polymers included Maltodextrin/VP copolymer and PVP.Primary energy use, material resource use, emissions to air, emissions to water, and land use were the factors considered for the analysis. Experimental evidence and literature published data were used to assign values to these factors. Environmental impact of the different cases was assessed using four different weighting scenarios based on current best practices in life cycle analysis (LCA).
Hair gels based solely on PVP have the highest environmental impact.Replacing PVP with Maltodextrin/VP copolymer significantly reduces the environmental impact in all four different weighting scenarios.The cradle-to-grave life cycle analysis serves to verify and validate the claims of improved sustainability that can be associated with the use of the Maltodextrin/VP copolymer in styling products.
Conclusions
A new hybrid polymer of maltodextrin and vinyl pyrrolidone enables the optimization of styling product formulation performance, properties and economics while simultaneously providing a more naturally-derived product composition. This new polymer allows the formulator to make styling aids that are more naturally derived and renewable without any compromise on cost, gel clarity, product aesthetics or on-hair performance.
This robust polymer is easy to use, has broad ingredient compatibility, and wide formulation latitude to allow for the creation of a variety of high-performance hair styling products, including styling gels, spray gels, mousses, creams, waxes and pomades with a more sustainable profile.
