Evonik solutions for deodorant and antiperspirant formulations:
- Rheology related effects such as thickening or stabilization
- Nature-identical ingredient
There is no compromise when it comes to deodorants and antiperspirants: Only a product that reliably protects against body odor is a good product. To fulfill this task, all ingredients must be of high quality and, above all, work together effectively in the formulation. In addition to reliable effectiveness, consumers value easy-to-use products that feel pleasant and dry on the skin and do not stain clothing.
Adding AEROSIL® fumed silica to antiperspirant and deodorant formulations can help to achieve the desired consistency for sticks, roll-ons and gels, as well as for aerosol or pump sprays. Evonik silica and silicate products also ensure an even distribution, suspension stability and re-dispersion of active ingredients such as antiperspirant salts. Moreover, silica meet the expectations of low-whitening formulations and the growing demand for products with natural or nature-identical ingredients.
In liquid formulations, dedicated silica types are used to adjust the rheology, so that roll-on antiperspirants and deodorants are fluid enough and easy to apply. In antiperspirants and deodorants sticks, AEROSIL® thickens the oil phase of wax/oil stick formulations and can improves its thermal stability by retaining an excellent pay off on skin. In the case of pump spray emulsions, special AEROSIL® types are available for stabilizing either oil-in-water (o/w) or water-in-oil emulsions (w/o).
Another type of silica, ZEOFREE® precipitated calcium silicate might curb the growth of odor-forming bacteria by influencing the pH-value by providing a very pleasant sensory on skin.
Silica for sustainable deodorant formulations
Silica is a multi-purpose raw material that has limited impact on the environment through its sourcing and production. As a naturally derived mineral ingredient complying with ISO 16128, it is an ingredient suited for organic and natural cosmetics. Moreover, the silica product range offers solutions for formulating deodorants and antiperspirants with a low-water approach, such as powders, sticks, bars and other solid products. Also, hydrophilic grades come with a COSMOS certification. In addition to that, all silica made by Evonik allows for vegan formulations.
