Organization from Germany posted this Technology CallSeeking multifunctional ingredient with antimicrobial properties for personal care applicationsPreservatives added to personal care product to control microbial spoilage, extend product shelf life and prevent infection in humans. Microbiological control is critical in the beauty industry because microbial spoilage will cause product degradation, leading to potential human health hazard. In recent years, due to growing human health concerns with traditional preservatives like paraben and Isothiazolinones (MIT/CMIT), consumers are drawn toward “’preservative-free’ or ‘self-preserving’ personal care formulations. Here, the company is seeking multifunctional personal care ingredients which apart from delivering its primary property also exhibits a certain level of antimicrobial activity. The ideal ingredients can be emollients, surfactants, rheology modifiers, solubilizer or bio-active. compounds/extracts that can also control microbial spoilage for skin and haircare applications.
Organization from Germany posted this Technology CallSeeking effective ways to combat malodours on surfaces in household areaMalodour is defined as an olfactory stimulant that when detected is considered to be offensive to the individual. Common malodours are often attributed to poor personal hygiene including halitosis, damp dog smells, tobacco smells, bathroom odours as well as damp clothing. Depending on the type and source of odour, specific solutions against it are necessary. The fight against malodours in the household area is time and energy consuming. For many consumers common ways e.g. masking of odour with fragrance are no longer adequate and more effective solutions are required. The company is searching for solutions that can be applied to consumer products to ensure long-term effectiveness in malodour control, especially focusing on new and effective means of eliminating malodours on soft surfaces (e.g. prevent the smell from lingering on clothes or fabrics), as odours can be deposited and easily trapped in materials. The company is specifically looking for a solution which contains active molecules that attract and eliminates malodours completely and permanently.
Organization from Germany posted this Technology CallSeeking eco-friendly bleaching and oxidative cleaving process for waxesWaxes are typically make up of linear or branched-chain hydrocarbon chains and can contain polar functionalities like e.g. ester or amide groups. Their importance has been well recognized, especially with the growing demand of modern consumer products like packaging, cosmetics and pharmaceutical. Plant-based or renewable waxes are also gaining favor in recent years due to higher sustainability compared to fossil based waxes. We are seeking sustainable green oxidative cleavage process that can convert renewable ester waxes, like rice bran wax and sugar cane wax, to similar end products obtained by conventional processes. Many oxidative cleavage processes are already established in the industry, but not many are eco-friendly. Furthermore, with the shifting focus from fossil waxes to plant-based waxes, alternative oxidative technologies do result in chemically different products from different plants. Here the company is keen to explore modern bleaching technologies or to work with technology-partners with bleaching experiences on renewable materials. The company is open to partners from any country and to a variety of cooperation. Research cooperation agreements with research organizations might yield into publications or consequent R&D contracts. Depending on the stage of technology readiness, an out-licensing of the process is possible or a joint venture might be a way to further develop for feasibility studies for a pilot scale up.
Organization from Germany posted this Technology CallSeeking hyperbranched, non charged, short molecules/dendrimers able to be coupled to keratinous surfacesWe are seeking for molecules/compounds/materials which are chemically composed of two opposite parts (see Fig.). The first part of such molecules has a hyperbranched/dendrimer-like/fork shape. The second part (which is geometrically opposit to the first) is a moiety which will favour attachement. The attachment on the skin or hair surface could be generated by adhesion, covalent bonding, electrostatic attachment etc. For instance such latter moieity could react with free amines present on the hair fibers (more attachment points on the skin and hair could be considered, e.g. hydroxyl groups). Lactone groups are an example reported in literature of a reactive moiety which upon heat application can bound to the free amine of the hair. Once bounded to the skin/hair such molecules will work as molecular spacers. The molecules need to be neutrally charged, rigid, branched and have a low particle density (number of atoms in a physical volume). They will therefore decrease the interaction (e.g. Van der Walls attactions) between external particles (such as sand or dust) and the functionalized surface. Example: N-Glycans are an example of such molecular spacers and an example of desired geometrical structure. Glycan with 5 Mannose units for instance will occupy a Volume of 2.25 x 1.65 x 1.24nm with 162 atoms, which lead to a particle density of 35 x 10(^27) atoms/m^3. Such lower particle density will lead to a reduction of the Hamaker-interaction coeffiecint between the funcitonalized surface and an approaching particle. Such molecule will therefore lead to a decrease of the friction coefficient and adhesion forces.
Organization from Germany posted this Technology CallSeeking coatings/materials to alter the wetting features of surfaces (e.g. Superhydrophobicity, Superamphphilicity etc.)We are interested in depositing a coating/primer/material on a soft/flexible surface (ideally the surface is a biological surface) in order to generate non conventional wetting behavior. The coating will impart to the surface one of the following effects: superhydrophobicity, superamphiphobicity or superamphiphilicity. The material composing the matrix of the coating will not be solubilized by water or oils (a small degree of swellability upon water or oil absorption, could be accepted) and will have good adhesion to the surface. The materials should leave a transparent/colorless and elastic/flexible and ideally non-occlusive coating.
