Abstract: Combinatorially generated peptides are provided that have binding affinity for polymethylmethacrylate (PMMA). The peptides may be used to deliver benefit agents to various PMMA surfaces.

Abstract: Combinatorially generated peptides are provided that have binding affinity for polyethylene (PE). The peptides may be used to deliver benefit agents to various PE surfaces.

Abstract: Combinatorially generated peptides are provided that have binding affinity for nylon (NY). The peptides may be used to deliver benefit agents to various NY surfaces.

Abstract: Peptide-based organic sunscreens, formed by coupling a skin-binding peptide with an organic sunscreen agent, are described. The skin-binding peptide part of the peptide-based organic sunscreen binds strongly to the skin, thus keeping the organic sunscreen agent attached to the skin for long lasting protection. Sunscreen compositions comprising the peptide-based organic sunscreens are also provided.

Abstract: A method for identifying shampoo-resistant hair-binding peptides is described. The shampoo-resistant hair-binding peptides bind strongly to hair from a shampoo matrix and are stable therein. Peptide-based benefit agents, such as peptide-based hair conditioners and hair colorants, based on the shampoo-resistant hair binding peptides are described. The peptide-based hair conditioners and hair colorants consist of a shampoo-resistant hair-binding peptide coupled to a hair conditioning agent or a coloring agent, respectively. Hair care and hair coloring product compositions comprising these peptide-based hair conditioners and colorants are also described.

Abstract: This invention relates to a bioprocess engineering solution for a product removal process for use in a biofermentation. The invention discloses a process for withdrawing an aliquot of broth from a biofermentation vessel during at least a portion of the biofermentation, removing biocatalyst and water, chromatographically separating biofermentation products from the withdrawn broth using water as an eluent, and returning the remaining components of the broth back to the biofermentation vessel. Process chromatography permits highly selective separation of the target molecule, preventing feedback inhibition of the biofermentation.
