摘要:
A process for producing an oxidized nanofibrillar cellulose hydrogel is disclosed, wherein the process comprises oxidizing cellulose pulp fibers in the presence of hypochlorite as an oxidant and a heterocyclic nitroxyl radical as a catalyst; and disintegrating the oxidized cellulose pulp fibers to obtain a nanofibrillar cellulose hydrogel; wherein all steps of the process after oxidizing are performed under aseptic conditions. An oxidized nanofibrillar cellulose hydrogel and a system for producing the same are also disclosed.

摘要:
Pre-moistened wiping articles are provided comprising a fibrous web impregnated with a liquid cleaning composition including an unstable dispersion of water, surfactant, and water insoluble polysaccharide particles such as natural starch and/or microcrystalline cellulose. Due to the instability of the dispersion the particles primarily reside on the surface of the fibers forming the fibrous web and are freely released from the web as a result of the mechanical and hydraulic forces associated with use of the article. The pre-moistened wiping articles are suitable for use in personal care applications including use as perineal wipes. Embodiments of the invention further include methods of making pre-moistened wiping articles comprising a fibrous web impregnated with the unstable dispersion.

Absorbent fibrous structure containing a polymeric fluid containing a polymer, including for example a copolymer and/or terpolymer, soil adsorbing agent, and absorbent fibrous structures containing such polymer soil adsorbing agents, and methods for making same.
摘要:
Disclosed herein are personal care compositions having at least one oligopeptide self-assembled into nanofibers or macrostructures, wherein the oligopeptide is 2-20 amino acids in length, and wherein the oligopeptide has at least one 0- to 10-amino-acid block of hydrophobic amino acids alternating with at least one 1- to 10-amino-acid block of hydrophilic amino acid residues. The composition may further include a dermatologically acceptable carrier and at least one cosmetic skin care agent.
摘要:
The present invention provides threads of hyaluronic acid, and/or derivatives thereof, methods of making thereof and uses thereof, for example, in aesthetic applications (e.g., dermal fillers), surgery (sutures), drug delivery, etc.
摘要:
There is provided a dissolvable film polymer matrix that includes a plurality of magnetically responsive kertin-like fibers for application to an individual's face or head. The dissolvable film polymer matrix product includes hairs that are magnetically oriented in a non-random plain to be applied on an individuals face or head to simulate the appearance of the individual's natural hair. Methods of manufacturing and applying the dissolvable polymer matrix product are also disclosed.
