Title:
SWAB WITH SOLUBILIZED COLLAGEN FIBERS
Document Type and Number:
WIPO Patent Application WO/2011/149113
Kind Code:
A1
Abstract:
Disclosed is a novel swab with solubilized fibers: that are crimped and do not have fiber separation defects (adherence of fiber bundles); within which the amount of water content and the amount of hydrophilic organic solvent are evenly distributed; and that dissolve instantly and uniformly when used. The swab with solubilized fibers has a composition comprising 66 to 87 wt% solubilized collagen, 2 to 6 wt% buffer salt, 10 to 22 wt% water content, and a trace amount to 6 wt% residual hydrophilic organic solvent (the total of the aforementioned is 100 wt%), and is 3 to 25 mm in diameter, weighs 3 to 20 mg, has an average fiber size of 3 to 10 dtx, and a length of 1 to 20 cm. The swab, which has a wavy shape and comprises uniform bundles of solubilized collagen fibers formed in a spherical shape, has a bulk density of 4.0 to 8.0 mg/cm3, and a swab diameter of 3 to 25 mm. The solubilized collagen fibers inside the swab are entangled in areas and are separated in other areas.
