Compared with extensive microemulsion phase-behavior studies, HLD reduces the number of experiments needed by capturing surfactant–oil interaction through empirical parameters. Detergency tests show an optimal HLD range for a given fabric surface, with evidence that the approach can translate to enhanced oil recovery and to ionic/nonionic blends. When paired with appropriate assumptions, experiments, and parameterization, HLD functions as an effective screening tool across surfactant applications.","Received: 15 August 2022 Revised: 27 December 2022 Accepted: 7 January 2023  \nDOI: 10.1002/jsde.12660  \nREVI EW  \nReview: Implementing the hydrophilic–lipophilic deviation model when formulating detergents and other surfactant-related applications  \nParichat Phaodee 1  | Javen Weston 2  \n1RD&E/Handcare Anchor, Ecolab Research Center, Eagan, Minnesota, USA  \n2College of Engineering and Natural Sciences, University of Tulsa, Tulsa, Oklahoma, USA  \nCorrespondence  \nParichat Phaodee, RD&E/Handcare Anchor, Ecolab Research Center, Eagan, MN 55121, USA.  \nEmail: [parichat.phaodee@ecolab.com](parichat.phaodee@ecolab.com)  \nAbstract  \nWhen designing surfactant formulations using ionic and nonionic surfactants, the hydrophile lipophile balance (HLB) is a generalized surfactant characterization parameter that has shown to be useful when designing surfactant formulations, in the case of both ionic and nonionic surfactants (Davies’ and Griffin’s methods) . Microemulsion phase behavior studies have been extensively used to optimize surfactant formulations, but these studies can cover a very wide phase space and can often encounter troublesome non-equilibrium issues such as coacervation. Detailed phase behavior studies can be time-consuming and difficult to apply beyond the specific surfactant-oil system studied. The hydrophilic–lipophilic deviation (HLD) provides a method to help expedite surfactant formulation research by reducing the number of phase behavior studies required to optimize a given formulation. Detergency experiments have indicated that there is an optimal range of HLD for a given fabric surface. This appears to apply to other applications, as well, for example, surfactant formulations used in enhanced oil recovery have been optimized using the HLD method. These studies found that the HLD can reflect total oil recovery, even if the surfactants were derived from different alcohol feedstocks (e.g., HLD of 0 would describe optimum conditions regardless the type of surfactant) . Also with additional parameterization, the HLD method can also be applied to nonideal surfactant mixtures, specifically ionic/nonionic blends. Overall, the HLD framework has shown to be an effective screening tool for a wide range of surfactant-related applications when appropriate experiments, assumptions, and understanding of surfactant and oil interactions are used to generate the HLD parameters.  \nKEYWORDS  \nanionic surfactants, application of surfactants, cationic surfactants, detergent formulation, non-ionic surfactants  \nINTRODUCTION  \nDrs. David Sabatini and Jeffrey Harwell have made significant contributions and inspired numerous researchers in the area of applied surfactant science during their times at University of Oklahoma. In honor of their retirement from teaching and researching, this article compiles previous work on the use of the hydrophilic– lipophilic deviation (HLD) model when formulating detergents and other surfactant formulations. The HLD  \nhas been an important part of their work across a wide variety of applications.  \nHydrophile lipophile balance (HLB), phase inversion temperature (PIT), and microemulsion phase behavior have been adopted in surfactant research and development for detergents, enhanced oil recovery, and consumer products (Boza Troncoso & Acosta, 2019; Chenget al. , 2020; Griffin, 1949, 1954; Ilec et al. , 2009 ; Mankowich, 1964; Storm et al. , 1976; Whanget al. , 2001) . However, these approaches have their own  \n2  \nJOURNAL OF SURFACTANTS AND DETERGENTS  \ndrawbacks and limitations. For example, the HLB for ionic surfactants does not allow for the inclusion of some surfactant structural features (i.e., tail branching; Do et al., 2009) . Meanwhile, phase behavior studies are timeconsuming experiments and very dependent on the specific surfactant-oil systems studied. The HLD concept has gained wide interest as an alternative to these approaches and has the ability to expedite surfactant research and development.
