Silicone polymers have the unique ability to lower the surface tension of organic oils and thereby present a different aesthetic effect in cosmetic formulations. This allows silicone polymers to be added at less than 10% concentration and often less than 5% concentration and provide a different customer experience than achieved by standard silicones.
Since the formulation is 90%+ identical to the starting formulation, the time and work needed to evaluate change is minimised. Likewise, the toxicology of the formulation, the need for many raw materials and the cost change is minimised.
In 2015 we have started using a concept we refer to as minimally disruptive formulation (MDF) as an effective approach to product development.1 This approach depends upon the ability of personal care formulators to provide products that have consumer perceptible differences that meet a market need. Since product aesthetics are a key attribute of personal care products, the ability to alter product aesthetics to provide a different consumer perception with minimal change to the formulation is a very cost effective way to develop new products.
This article will show the concept in a moisturiser that will be transformed into a cationic moisturiser. As silicone polymers continue to rise in price, using low levels of these materials added to a formulation is the best approach to get the benefit of silicone at a cost effective level.
