Adequate lather is an important factor to consumers when they select toiletries. Another preference is long-lasting and weak acidity (pH 4.5–6.0) on the skin and scalp, which maintains healthy normal skin conditions while suppressing the growth of undesirable microbes and skin irritation. These preferences are met by a noticeable trend in product development to formulate silicones, higher alcohols and a variety of functional materials into toiletries. However, such ingredients, along with primary surfactants, generally suppress lather, and their use can result in slow foaming or reduced volume of foam.1 Thus, there are strong demands from the industry for an ingredient such as an adjuvant surfactant that is compatible with the complicated and diverse formulae necessary to meet consumer demands for both long-lasting, weak acidity and lather. The author describes efforts to develop such a surfactant here.
