Fresh ideas for the development of a stain-free deodorant.
In the manufacture of cosmetics, the focus is on the interaction of product and skin, often without considering how cosmetics and textiles react with each other. This may result in unpleasant stains or discolourations on garments.
Antiperspirants should primarily prevent the development of unpleasant odours. They also contribute to the pleasant feeling of having dry armpits. It is not just the odour of sweat that is unwanted - it can also cause unwelcome wet patches on clothing. Using an antiperspirant on the skin can even leave white residue from the product on the textiles. Worse, however, are stains which are often yellow and which are formed during washing by the chemical reactions between bodily substances and the ingredients in antiperspirants or their accumulation on the textile surface. These look unattractive and are often so stubborn that they cannot be removed by regular domestic washing. A well-known cosmetics manufacturer recognised that, in addition to chemical knowledge, textile and textile chemical expertise was also needed to resolve this problem. So they turned to us.
Experience that does not make us break out in a sweat.
By means of a stain-removal seminar and cooperation within the scope of small projects, Hohenstein became a textile expert for this cosmetics manufacturer and also a competent contact partner for issues relating to the interaction of textiles and cosmetics. This interdisciplinary knowledge from the fields of stains, washing, comparative product tests, wearer studies on test subjects, colour measurement and in-vitro experiments in the laboratory significantly helped us to be able to develop solution approaches. After all, the right conclusions can only be drawn when the interactions of all components have been considered.
An impressive result – because it cannot be seen.
Our research was characterised by lively discussion and quick decisions. We thus created a unique test environment which reproduced the problem stains as realistically as possible – by means of wearer trials on people and in the laboratory. In doing so, we discovered new approaches to stain prevention which were both skin and textile-friendly. We thus contributed to the development of the product, which was not yet available on the market in this form: a high-performance antiperspirant with visibly fewer residues and stains. Whether on light or dark clothing. Hence the name: “Black&White”.
The chemistry is right. For the next stages too.
Hohenstein has been a dedicated contact partner for this company since the development of the antiperspirant whenever questions arise on the interactions of cosmetics with textiles. The response to the “invisible deodorant” was so good that follow-on projects were launched. For example, for a new sun cream we developed a textile-chemical solution approach which helps to reduce the intensity of sun cream stains after washing.
We think of ourselves as solution providers who make available expertise at each point in the textile value creation chain. In this case, our customer also benefitted from the services listed here. Since textiles are an integrated part of our life and are also constantly developing, we are happy to work with you on new solutions which are tailored to your individual application case.
