Personal Care Solids & Concentrates – How to Formulate Waterless Beauty Products

Webinar | Distributors


Water is found in some 80% of all cosmetic products. A closer look at the list of ingredients will show you that in most cases, water is the first thing mentioned, i.e. water is usually the main ingredient.

There are sound reasons for this. Water is extremely cost-effective and an excellent solvent for a great many ingredients. It also gives formulations a light and fresh feel.

This runs counter to the current trend for waterless products. These formulations are supplied either as a solid or as a concentrate and do not require any water.

A major advantage of solid cosmetics is that they are seen as being more environmentally compatible. Thanks to their solid consistency, you can either do without plastic packaging entirely or you can greatly reduce the amount needed, unlike with liquid products. Another positive environmental aspect is that solid or highly concentrated cosmetics are lighter in weight and are therefore easier to transport.

There are also various technical factors that speak in favor of solids and concentrates, however. A formulation that contains water always runs the risk of microbiological contamination. That is why preservatives are added to keep the formulation totally hygienic. Despite their many benefits, some of these preservatives are the subject of heated debate, especially as regards their potential skin-sensitizing action. Waterless cosmetic formulations, in contrast, often do not need any preservatives whatsoever.

Yet from the point of view of cosmetics manufacturers, cosmetic solids and concentrates pose a real challenge. The product form is not at all new, though. Take the example of solid soap, which has been in use for thousands of years. Of course, consumer demands have changed enormously over time. Today, we expect a solid cosmetic formulation to have the same properties as their water-containing counterparts.

A solid shampoo must therefore disperse quickly and form a dense foam while you wash your hair. After the shampoo has been applied, your hair should feel nice, be easy to comb and look naturally glossy. What’s more, there shouldn’t be any annoying soap marks left in the bathroom.

A solid body-lotion stick should glide gently over your skin while applying a defined amount of lotion. The product should be easy to spread over the skin and have a nurturing and moisturizing effect. The stick itself should in turn be very stable and exhibit consistent properties over a broad range of temperatures.

For this reason, there is a precisely defined requirements profile for each grade of cosmetic solid and concentrate.

We will use this online seminar to offer you product recommendations and formulation advice regarding technical support. Based on specific formulation examples developed in a wide range of WACKER laboratories around the world, the seminar aims to give you a grounding in discussing the “Solids & Concentrates” trend with customers.
