“…Generally, a suitable combination of at least two nonionic surfactants should be used at a minimum level of 2% and up to 5% in a skin moisturizer 7,57 . The final HLB value of the combination should be between 8 and 15 to assure a stable O/W emulsion.…”

“…Emulsifiers Generally, a suitable combination of at least two nonionic surfactants should be used at a minimum level of 2% and up to 5% in a skin moisturizer. 7,57 The final HLB value of the combination should be between 8 and 15 to assure a stable O/W emulsion. This value is generally achieved by combining one part of a medium HLB (9-15) emulsifier, three to six parts of a high HLB emulsifier (>16), and two to six parts of a low HLB emulsifier (<8).…”

“…Because quality factors are sometimes qualitative or subjective, performance metrics need to be established. To improve the traditional trial‐and‐error procedure during this phase, many authors have developed a knowledge basis for the identification of the consumer needs, the inclusion of suitable categories of ingredients, and the desired end‐use properties, particularly in the case of cosmetics and personal care products 7‐14 . In the context of emulsions, Mattei et al 14 proposed such a knowledge basis, including consumer needs, categories of ingredients, and product properties with target values and intervals of acceptance.…”

However, one of the main challenges still to be solved is the formalization of the consumer needs and their translation into measurable properties, namely for product attributes whose assessment is inherently subjective, such as those related to human senses.…”

Design of formulated products integrating heuristic knowledge and consumer assessment

This work proposes a systematic approach for the design of formulated products incorporating consumer assessment and heuristic knowledge. The methodology is divided into two main phases: Consumer assessment and product realization. In the first part, product attributes valued by consumers and their interactions are identified through usability tests performed on a reference product, and fuzzy integral analysis. In the second phase, alternative product formulations are generated using a mixedinteger optimization approach, which incorporates heuristic rules regarding the choice of ingredients and their amounts. The results from the consumer assessment phase are transformed into additional heuristics and incorporated into the design. Different alternative formulations are generated at a lab-scale, by using two commercial skin moisturizers as references. Those formulations that included additional heuristics are shown to be more similar to the references. As a result, the incorporation of consumer preferences significantly reduced the time and resources spent on the design process.

“…To improve the traditional trial-and-error procedure during this phase, many authors have developed a knowledge basis for the collection of the consumer needs, their translation into necessary categories of ingredients, and the desired end-use properties, particularly in the case of cosmetics and personal care products. [6][7][8][9][10][11][12][13] In the context of emulsions, Mattei 13 proposed such a knowledge basis, including consumer needs, categories of ingredients, and end-use properties with target values and boundaries of acceptance. However, one of the main challenges still to be solved is related to the formalization of the consumer needs and their translation into physicochemical properties, namely for product attributes of which assessment is inherently subjective, such as those related to human senses.…”
