Testing and Developing a Sugar-derived Surfactant Blend for Delicate Skin

Jul 1, 2014Luigi Rigano, PhD, and Nicola Lionetti, Rigano Industrial Consulting and Research, Milan, Italy; Adriana Bonfigli, PhD, ISPE Srl, Milan, Italy; Giambattista Rastrelli, PhD, Kalichem Italia Srl, Botticino Sera, Brescia, Italy; and Andrea Baratto, Unifarco Srl, Santa Giustina, Belluno, Italy

Vegetable-derived, mild and sustainable skin cleansing ingredients are in demand, and this has led to the development of new detergent structures. Described here is a combination of two mild surfactants that fulfils these requirements using the concept of “interrupted soap” to impart mildness. Studies to verify the functional, sensorial and mild characteristics of the new blend are detailed.

Measuring and Pre-selecting Functional Filler Pigments

May 1, 2012Miriam Becker, Christoph Schmidt, PhD, Veronika Hochstein and Xenia Petsitis, Merck KGaA, Darmstadt, Germany

Functional filler pigments play an important role in adjusting optical properties such as transparency and soft focus effects in cosmetics. However, their suitability for specific formulas is not apparent until time-consuming tests using many different fillers have been conducted. Therefore, a new method to predetermine the soft focus effects of functional filler pigments is described here.

Evaluating Hair Conditioning with Instrumental Combing

Aug 1, 2011Trefor Evans, PhD, TRI/Princeton

When formulating a hair care product, there is often a need for testing that validates the product’s technical performance. This testing provides guidance to create formulas with appropriate performance, while also communicating the product’s message to the consumer. This article discusses the use of instrumental combing measurements when formulating hair conditioning products.

Evaluating the Physiochemical Properties of Emollient Esters for Cosmetic Use

Dec 1, 2010Mihaela Gorcea and Donna Laura, International Specialty Products (ISP)

This study assesses the physicochemical properties of four known cosmetic emollient esters in vitro to predict their sensorial benefits and correlate their properties with in vivo sensory attributes. This evaluation serves as a guide to selecting specific emollient esters for various cosmetic applications and to predicting their sensory attributes.
