The component of molecular weight 10,000 or less (A) ratio 3 - 46 mass % is new hyaluronic acid and/or that salt, andPROBLEM TO BE SOLVED: To provide hyaluronic acid and/or its salt excellent in an absorption property into a living body using a cosmetic, a pharmaceutical composition, ...
Themolecular weightof a solvent is a standard but underutilized component of the information on properties of solvents. Many solvent properties depend directly on theirmolecular weights. The hypothesis of Hildebrand-Scratchard states that solvent-solute interaction occurs when solvent andpolymer segmenthave...

Although a slight variation is observed between the peaks of the higher molecular weight component, the agreement is quite satisfactory. However the resolution of GPC is not suf- ficiently high to enable the two peaks in the chromatogram of sample No. 11 to be distin- guished. Sedimentation ...
(referring to either the entire biopolymer or a biopolymer segment) interact with each other by electrostatic attraction, and ultimately form polyelectrolyte microdroplets termed the complex coacervate phase. Coacervation can also occur by an inter-molecular association of a single component, known as ...

According to the four-component method of asphalt, asphalt can be divided into the saturate, aromatic, resin, and asphaltene [17]. Because asphalt was extremely complex [18,19] and the molecular weight of a single molecule was large, it was not easy to calculate using real asphalt molecule;...
