Disclosed is a method of crosslinking hair or other keratin fibers by (i) providing a crosslinking agent comprising an oxidized sugar having at least two aldehyde groups; and (ii) infiltrating a plurality of non-crosslinked hair or other keratin fibers with the crosslinking agent under conditions effective to cause protein molecules contained in the non-crosslinked hair or other keratin fibers to become crosslinked, thereby yielding a population of crosslinked hair or other keratin fibers. The protein molecules include amine groups that react with the aldehyde groups of the oxidized sugar to yield the crosslinked hair or other keratin fibers. Also disclosed are formulations for crosslinking hair or other keratin fibers and methods of using the formulations to treat human hair to maintain a desired three dimensional structure. This formulation includes a crosslinking agent having a plurality of oxidized sugars having at least two aldehyde groups or mixture thereof.

Peptide-based systems containing hydrophobic amino acids (e.g., tryptophan), charged amino acids (e.g., arginine), and/or sulfur-containing amino acids (e.g., cysteine), which can be used either alone or in combination with nanoparticles (e.g., gold or silver nanoparticles) for siRNA delivery into living cells are disclosed.

A degradation product produced by degrading a composition containing a hyaluronic acid and a protein with a protease has a pain relieving effect, a joint function ameliorating effect, a cholesterol-lowering effect, a hypoglycemic effect and a diastolic blood pressure-lowering effect.

A cosmetic composition exerts a high improving effect on a texture of hair of a head or a scalp. The cosmetic composition includes nucleic acid, succinic acid, alanine, citric acid, and glycine. An amount of the nucleic acid is 6.6 to 11.5% by mass based on a total mass of the composition, and an amount of the citric acid is 7.1 to 17.4% by mass based on the total mass of the composition. The cosmetic composition is allowed to contain at least one member selected from, for example, histidine, arginine, proline, isoleucine, serine, valine, aspartic acid, threonine, phenylalanine, pyrrolidonecarboxylic acid, sodium pyrrolidonecarboxylate, sodium lactate, and water to prepare a cosmetic.

A three-part method of cleaning a user's teeth and/or gums is disclosed. First, a user applies a tonic of essential oils to the user's teeth and/or gums by either brushing, rubbing, rinsing and/or flossing with the tonic thereby destroying harmful bacteria. Second, the user brushes with a toothpaste having nano-hydroxyapatite being particles of 50 nanometers or smaller. The nano-hydroxyapatite is absorbed into the surface opening inside dentinal tubules of the teeth. Third, the user seeds their mouth with an oral probiotic having beneficial bacteria. The third step must come after both the first and second steps.

A natural edible shampoo and preparation method thereof, the components comprises fatty acyl lactyl-lactic acid, arginine, vegetable oleic acid monoglyceride, plant phospholipid, ε-polylysine, ethyl lauroyl arginate hydrochloride, inulin, polyol and so on. It resist static electricity, improve the smoothness of hair, prevent pore clogging, and has good flowability at a low temperature. The shampoo overturns the classic concept of existing cationic hair care (large irritation), uses nearly non-irritant natural anionic wash and care main ingredients, relies on a non-enclosed protein peptide/low HLB value oiliness agent film-forming smoothing system, avoids a cationic polymer/silicone oil hair-care pattern with intensive negative effect, and protects the original ecological environment of hair and scalp, so that a final product gains the smooth experience feeling of organic silicone oil, thereby creating a new path for research and development of food and cosmetic-type wash and care two-in-one shampoos.

Methods and aqueous compositions for styling or reshaping keratinous fibers such as human hair are provided. An aqueous styling composition includes (a) 0.5 to 15.0% by weight of at least one disaccharide; and (b) 0.01 to 20.0% by weight of at least one alkali salt and/or alkaline earth salt, wherein the composition is free of synthetic film-forming polymers.
