Chlorine-stable machine dishwashing products

The increasing use of active chlorinecontaining compounds in machine dishwashing has led to the need for chlorine-stable, low foaming detergent formulations. To avoid oxidative degradation of nonionic surfactant and simultaneous loss of available chlorine, a new basic formulation process has been devised. This obviates the need for modifying nonionic surfactants. The process requires a preferred order of addition and the use of tetrasodium pyrophosphate builder as an integral part of the composition. The detergent product is free-flowing, granular, readily soluble and exhibits no tendency to cake on storage. A suggested machine dishwashing formulation is given, and data are presented which show good chlorine stability and excellent dishwashing performance. Presented at the AOCS-AACC Joint Meeting, Washington, D.C., April 1968.

An Integrated Approach for the Design of Emulsified Products

Consumer-oriented chemical-based products, including emulsified ones, are structured products constituted by numerous chemicals, and they are used every day by millions of people. They are still mainly designed through trial-and-error-based experimental techniques. A systematic approach, integrating model- and experiment-based techniques, for design of these products could significantly reduce both time and cost connected to product development by doing only the necessary experiments and ensuring chances for innovation. In this work, we present an integrated methodology for the design of emulsified formulated products. The methodology consists of three stages: the problem definition stage, the model-based design stage, and the experiment-based verification stage. In the problem definition stage, the consumer needs are translated into a set of target thermophysical properties and into a list of categories of ingredients, which are to be included in the formulation via a robust knowledge base. In the model-based design stage, structured databases, dedicated algorithms, and a property model library are employed for designing a candidate base case formulation. Finally, in the experiment-based verification stage, the properties and performances of the proposed formulation are measured by means of tailor-made experiments. The formulation is then validated or, if necessary, refined thanks to a systematic list of actions. All these tools have been implemented as a new template in our in-house software called the Virtual Product-Process Design Laboratory and have been illustrated via a case study (a hand wash detergent) where the complete methodology (all three stages) is for the first time applied. © 2018 American Institute of Chemical Engineers AIChE J, 65: 75–86, 2019     

Coacervates as a Modern Delivery System of Hand Dishwashing Liquids

Hand dishwashing liquids can be produced in a coacervate form. Such a delivery system can be readily mixed with water and, in the initial dilution stage, may exhibit a high viscosity. This makes it feasible to formulate concentrated products which can be diluted by consumers. The surfactant concentration in the starting formulation is found to affect the possibility of producing hand dishwashing liquids in coacervate form. Hand dishwashing liquids in coacervate form are produced by the separation of the upper phase under the effect of sodium chloride, whose concentration is a key parameter. An increase in the concentration of anionic surfactants in the starting formulation, requires a slight increase in the concentration of sodium chloride to start coacervation and this results in an increase in coacervate volume. The properties of the coacervate, i.e. viscosity, washability, emulsifying power and foamability, are reported and found to be similar to those of typical commercial products.
