Abstract
The present invention relates to a parenteral bioactive substance delivery composition and a bioactive substance carrier using a micelle based on low molecular weight methyl cellulose with a weight average molecular weight of 6 to 9.5 kDa. The low molecular weight methyl cellulose with a weight average molecular weight of 6 to 9.5 kDa resolves a problem of excretion to outside of the body to improve safety and form a micelle to solubilize poorly soluble bioactive substances, and thus is very useful for sustained release parenteral bioactive substance delivery.
