The main goal is to find a technology to jellify a fluid without using macromolecules or concentrated surfactant systems. The fluid in question may be water or oils (eg. hydrocarbons, triglycerides, fatty acids and esters - mostly saturated). The concentration of the gelling agent should be below 5% w/w. (preferentially < 2% w/w).
Details of the Technology Call
SHOULD HAVE (we are open for your ideas, so proposals slightly out of these limits are also welcome):
- The desired thickening/jellifying agent should be a small molecule (molecular weight below 1000 g/mol) or inorganic particles that are able to increase the viscosity of water or oils.
- The formulations are to be used in skin care products, so a toxicologically safe profile is mandatory.
- Preferentially, toxicology, genotoxicity, ecotoxicity and degradability data for the proposed agent should be available.
- Sensibilization and skin compatibility data would also be appreciated
MUST NOT HAVE:
- Polymeric molecules should not be used.
Technical requirements
SHOULD HAVE (we are open for your ideas, so proposals slightly out of these limits are also welcome):
- The concentration of the gelling agent should be below 5%, and preferentially below 2%.
- The gelling agent should preferentially work in a range of pH from 4 to 9.
- The gelling agent should also be effective in the presence of electrolites (up to 2% wt. NaCl).
- The gelling effect should be visible at room temperature (25ºC).
- Storage modulus (E') is expected be higher than the loss modulus (E'') by at least one order of magnitude at low shear rates (1 to 10 1/s).
- The resulting gel should flow under higher shear rates - however, the structure must be recovered when the material is again at rest.

All around the world we at Beiersdorf follow the same ambitious goal: Being the number 1 skin care company. Throughout our history we have continuously built trust by staying close to our consumers and developing innovative skin care products that are tailored to their needs. As we head into the future, our global brand icons, such as NIVEA, Eucerin, Labello and Hansaplast, ensure that globally over 500 million people feel good in their skin.
We are skin care.
And when it comes to research and development, we at Beiersdorf have relied on the integration of external knowledge for many years. Our open innovation activities are collected under the motto “PEARLFINDERS – We Open Innovation.” Different forms of trusted and close collaboration with strategic partners were developed within and with the Beiersdorf Research Center. In addition to maintaining our network with leading research institutes, universities and suppliers, we have systematically expanded our activities in this area. A central element since 2011 is our open innovation platform TRUSTED NETWORK (trusted-pearlfinders.beiersdorf.com).
