emerGinG trenDS are ChanGinG the WayFormulatorS thinK aBout, anD Formulate,SurFaCtant CleanSinG ProDuCtSToday’s consumers are more cognizant than ever of the health and safety aspects of the personal care products they buy.At the same time, changes in the world economy have made these consumers more value-conscious. Thus, formulators findthemselves challenged to change the way they formulate surfactant cleansing systems.FIGURE 2: Pearlescent cleansing formulations thickenedwith Carbopol ® Aqua polymers and NaClrefreshingcleansing.Aged 3 months @ 45ºCA. No PolymerB. Carbopol ® AquaSF-1 PolymerC. Carbopol ® AquaSF-2 PolymerCarBoPol ® aQua SF-2 PolymerINCI Name: Acrylates Crosspolymer-4Many traditional preservatives used in surfactant cleansing products havecome under scrutiny as they have been linked to potential health issues.As a result, formulators have begun using food-grade preservatives, suchas sodium benzoate, to preserve cleansing formulations. These naturalpreservatives require a pH near 5.0, which sacrifices desired formulationclarity and flow properties when using currently available rheologymodifiers. Carbopol ® Aqua SF-2 polymer enables formulators to buildattractive surfactant cleansing systems at low pH.FIGURE 1: Carbopol ® Aqua SF-2 polymer performance in a11.2 wt% TS SLES / 2.3 wt% TS CAPB surfactant systemKey Benefits of Carbopol Aqua SF-2 Polymer• Excellent clarity and suspension in low pH surfactant systems• Elegant rheology with a smooth, honey-like flow• Highly compatible with most common surfactants and sodiumbenzoate• Good salt synergy• Can be post-added to batches, increasing processingflexibility and decreasing likelihood of out-of-spec batchesthe BeneFitS oF merQuat PluS 3330PolymerS in SKin CleanSinG FormulationSINCI Name: Polyquaternium-39Merquat PLUS 3330 polymers are widely used in body wash,facial wash and hand cleansing formulations to enhancefoaming and lathering properties, as well as to mitigatesurfactant irritation for improved skin suppleness and afterfeel– all benefits desired by today’s discerning consumer.FIGURE 3: Reduction of irritation provided by 1 wt% TSMerquat PLUS 3330 polymer in a formulation comprisedof 12 wt% active Disodium Laureth Sulfosuccinate,5.5 wt% active Sodium Cocoamphodiacetate, 3.5 wt% TSCocamidopropyl Betaine, and 1.5 wt% activeIsostearamidopropyl Morpholine LactateCarbopol Aqua SF-2 polymer was designed specifically as a rheologymodifier and suspension aid in formulations with pH below 6.0. Figure2 shows the performance of Carbopol Aqua SF-2 polymer in a SLES/CAPB surfactant system (13.5 wt% TS surfactant, 2.5 wt% TS polymer).Carbopol Aqua SF-2 polymer efficiently builds viscosity while maintainingclarity at low pH.Another benefit of Carbopol Aqua SF-2 polymer is its ability to suspendinsoluble particles, allowing the formulator to make visually appealingpearlescent cleansing formulations (Figure 2).Mean Primary DermalIrritation Score5.04.54.03.53.02.52.01.51.00.5048 Hours 72 Hours 120 HoursShower Gelwithout PolymerShower Gel withMerquat PLUS3330 PolymerKey Benefits of Merquat PLUS 3330 Polymer• Delivers rich, creamy lather in cleansing formulations• Enhances the mildness of cleansing formulations bymitigating the irritation of common surfactants• Conditions the skin, leaving it soft and supple• Ideal for use in cleansing formulations where mildnessis desired

Novethix L-10 PolymerINCI Name: Acrylates/Beheneth-25 Methacrylate CopolymerMany formulators are struggling to find ways to reduce product costs bydecreasing certain ingredient levels in formulations. However, formulatingat reduced surfactant levels can make it difficult to thicken the formulationwith salt while maintaining clarity.formulate clear systems with them. Glucamate VLT thickener is a highlyefficient associative thickener for building viscosity in amino acid-basedsurfactant systems (Figure 6).FIGURE 6: Associative thickening of 15 wt% TS amino acidsurfactant systems with Glucamate VLT thickenerAnother trend in the market is the move toward sulfate-free surfactants,which deliver a desirable blend of mildness and pleasant sensory toformulations, but can be very difficult to thicken using salt. Novethix L-10polymer has been shown to thicken sulfate-free surfactant formulationsefficiently, producing elegant cleansing formulations (Figure 4).FIGURE 4: Viscosity performance of Novethix L-10 polymer in asulfate-free, non-ethoxylated surfactant systemKey Benefits of Novethix L-10 Polymer• Delivers efficient thickening in low surfactant, economy formulations• Depending on the surfactant system, 0.5 to 1.0 wt% TS of NovethixL-10 polymer is sufficient to obtain elegant rheology• The synergy of Novethix L-10 polymer and salt provides formulationflexibility and excellent viscosity control• Is a liquid emulsion polymer; no heating is required and allows foreasy addition to the formulation• Maintains stable viscosity, even at elevated temperaturesNEW Glucamate VLT thickenerINCI Name: PEG-120 Methyl Glucose Trioleate (and) PropanediolGlucamate VLT thickener builds viscosity in surfactant systems through anassociative mechanism. By forming bridges between surfactant micelles,Glucamate VLT thickener reduces the critical micelle concentration(CMC) of surfactants, decreasing the amount of free surfactant monomerand reducing the irritancy of the formulation (Figure 5).FIGURE 5: Glucamate VLT thickener reduces the dermal irritancyof an SLES-2/SLS/CAPB surfactant blendKey Benefits of Glucamate VLT Thickener• Naturally derived from corn• Improved sustainability and cost-in-use• Efficient viscosity builder• Designed for anionic, amphoteric and nonionic surfactant systems• Synergistic thickening with surfactants and salt• Excellent clarity• Exceptionally mild and non-irritating to eyes and skin• Very light, pleasant skin feelChemoryl SFB-10SK SurfactantINCI Name: Disodium Laureth Sulfosuccinate (and) SodiumCocoyl Isethionate (and) Cocamidopropyl BetaineChemoryl SFB-10SK surfactant is an alkyl and alkyl ether sulfate-free,amide-free, mild multi-purpose surfactant concentrate. Its gentle, richformula is ideally suited for premium shampoos and body washes. At 47%by weight dilution, it forms an easily rinsed shampoo with exceptionalfoaming. Shampoos formulated with Chemoryl SFB-10SK surfactant leaveall hair types clean, soft and lustrous. Premium quality body washes maybe formulated with 40-50% by weight dilution, which produces a bodywash with clean rinsing, rich, thick lather.INCI DescriptionDisodium Laureth SulfosuccinateSodium Cocoyl IsethionateCocamidopropyl BetaineFunctionPrimary foaming andcleansing agentMild foam builder andcleansing agentFoam booster, cleansingagent, irritation reducerIn an effort to formulate milder products, formulators are looking atusing amino acid-based surfactants.
