Problems solved by technology

However, while increasing the amount of certain components in the composition can improve the composition's odor suppression ability, this often results in a compromise of other desired properties of the composition, such as centrifuge retention capacity (CRC) and absorbency against pressure (AAP )

example

[0056] The following examples are presented to aid in the understanding of the disclosed embodiments and should not be construed as specifically limiting the embodiments described and claimed herein. Such changes in the examples including substitution of all equivalents now known or later developed and changes in formulation or minor changes in experimental design within the purview of one skilled in the art are considered to be incorporated herein within the scope of the examples.

[0057] Unless stated otherwise, the measurements of the following examples were carried out at an ambient temperature of 23±2° C. and a relative air humidity of 50±10%. Mix the water-absorbent polymer particles well before performing any measurements.

[0058] The following method was used in each of the following examples to determine bacteria-induced ammonia release. Brain heart infusion (BHI) medium was inoculated to OD=0.1 with Proteus mirabilis ATCC 14153 and incubated in a 10 mL test tube ...

example 1

[0079] in 5L In a plowshare mixer, 1 kg of HySorb T6600 superabsorbent (brewed to have 0.35 wt% Compound A) was mixed at 265 rpm. While mixing, a solution of 10 parts of molten 1,2-decanediol (Aldrich Chemical Company) was added by means of a spray tip syringe over 5 minutes. This gives 1.0 wt% 1,2-decanediol loaded T6600.

example 2

[0081] The procedure of Example 1 was repeated substituting 5 parts of molten 1,2-decanediol for 10 parts of the solution. This gives 0.5 wt% 1,2-decanediol loaded T6600.

Abstract

Disclosed herein are embodiments of odor-inhibiting compositions and hygienic articles incorporating the same. In some embodiments, an odor-inhibiting composition comprises water-absorbing polymer particles; a first odor control agent comprising a chelation agent; and a second odor control agent.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 779,453, filed December 13, 2018, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] Water-absorbent polymer particles, also known as superabsorbents, are used in odor control compositions for diapers, tampons, sanitary napkins and other hygiene articles. The properties of the water-absorbing polymer particles can be adjusted in various ways, eg by adjusting the amount of crosslinking within the polymer matrix of the particles. However, while increasing the amount of certain components in the composition can improve the composition's odor suppression ability, this often results in a compromise of other desired properties of the composition, such as centrifuge retention capacity (CRC) and absorbency against pressure (AAP ). Contents of the invention [0004] The following presents a s...
