NON-REWETTING O/W (OIL IN WATER) EMULSIFICATION SYSTEM FOR HYDROPHOBIC COMPOUNDS
An emulsified liquid composition is disclosed comprising a hydrophobic phase, an emulsifying composition of a protonated amide and a protonated amine having defined carbon to nitrogen atom molar ratios and water. The compositions optionally comprise at least one of a defoamer, a coalescent agent, a preservative, a co-emulsifier, chain extender, crosslinker and a rheology modifier. The compositions are useful for application to induce hydrophobicity to inorganic, organic or fiber based materials without undesirable backwetting or re-wetting effects.

MODIFIED NATURAL MATERIAL AND USE THEREOF
An oil repellent agent including a modified natural product having at least one hydroxyl group, wherein a hydrogen atom of the hydroxyl group is replaced with an R group represented by —Y—Z, wherein Y represents a direct bond, —C(═O)—, —C(═O)—NR′— or —C(═S)—NR′—, where R′ represents a hydrogen atom or a C.sub.1 to C.sub.4 alkyl group); and Z represents a hydrocarbon group having 1 to 40 carbon atoms and optionally having a substituent or a polysiloxane. The natural material is a natural product other than starch and preferably is a monosaccharide, a polysaccharide, glycerin or polyglycerin. Also disclosed is a textile product to which the oil-resistant agent is attached, an oil-resistant paper and a method of treating paper with the oil-resistant agent.

Insect-Resistant Fabrics Including Micellar Systems
The present disclosure is directed to insect-resistant fabrics or garments and methods for making the same. The insect-resistant fabrics or garments include an insect repelling composition containing a micellar system and optionally an insecticide composition. As an example, an insect-resistant fabric in accordance with the disclosure can include a base fabric (e.g., polyester) having been treated to include an insect repellant composition containing a micellar system. The micellar system may include one or more insect repelling agents (e.g., essential oils) contained within one or more micelles (e.g., saponins) in a first region of the fabric, and optionally an insecticide (e.g., permethrin) in second region of the base fabric. The inclusion of a micellar system in an insect repellant composition is shown herein to provide improved insect-resistant efficacy. Additionally, certain insect-resistant fabrics disclosed herein can also demonstrate durability when exposed to wear such as laundering the garment.
FLUOROCARBON-FREE AND BIOBASED OIL AND WATER BARRIER MATERIALS COMPRISING POLYELECTROLYTE COMPLEXES
The present invention relates generally to compositions comprising polyelectrolytes complexes (PECs) of anionic and cationic biopolymers capable of forming barriers on fiber based materials. Also disclosed is a fibre based material with a barrier coating against oil and water, wherein the material is provided with a barrier from at least two layers formed from at least one composition comprising a polyelectrolyte complex (PEC) of a cationic biopolymer and an anionic biopolymer, The two layers result in improvements in both oil resistance and water resistance compared to the same material provided with a single layer of said at least one composition.
