Abstract
Official abstract text for this publication.
To provide a composition for wet indicator which is excellent in discoloration performance and is suppressed in odor. What is disclosed is a composition for wet indicator comprising: a hydrocarbon oil (A), at least one selected from saturated fatty acids having 16 or more carbon atoms and derivatives thereof (B), and a wet-sensitive colorant composition (C), wherein the component (B) is contained in an amount of 2 to 85 parts by mass based on 100 parts by mass of the total amount of the components (A) to (C).
First claim
Opening claim text (preview).
The invention claimed is: 1 . A composition for a wetness indicator, the composition comprising: a hydrocarbon oil; at least one saturated fatty acid selected from saturated fatty acids having 16 or more carbon atoms and derivatives thereof; and a wet-sensitive colorant composition comprising a colorant and a surfactant, wherein: the at least one saturated fatty acid is present in an amount of from 2 to 85 parts by mass, based on 100 parts by mass of the total amount of the composition, the hydrocarbon oil and the at least one saturated fatty acid are in the form of a crosslinked gel, the colorant undergoes discoloration in the presence of protons, and the surfactant releases protons in the presence of water. 2 . The composition of claim 1 , wherein the at least one saturated fatty acid is selected from 12-hydroxystearic acid and metal salts of 12-hydroxystearic acid. 3 . The composition of claim 1 , wherein the colorant is a leuco dye. 4 . The composition of claim 3 , wherein the wet-sensitive colorant composition further comprises a pH indicator. 5 . A wetness indicator having the composition of claim 1 . 6 . An absorbent article having the wetness indicator of claim 5 . 7 . The composition of claim 1 , wherein the surfactant is a nonionic surfactant. 8 . The composition of claim 1 , wherein the surfactant is an anionic surfactant. 9 . The composition of claim 8 , wherein the anionic surfactant is a linear alkylbenzene sulfonate. 10 . The composition of claim 1 , wherein the hydrocarbon oil has a weight average molecular weight of from 200 to 2000. 11 . The composition of claim 1 , wherein the hydrocarbon oil is present in an amount of from 5 to 90 parts by mass, based on 100 parts by mass of the composition. 12 . A composition for a wetness indicator, the composition comprising: a hydrocarbon oil; at least one saturated fatty acid selected from saturated fatty acids having 16 or more carbon atoms and derivatives thereof; and a wet-sensitive colorant composition comprising a leuco dye, wherein: the at least one saturated fatty acid is present in an amount of from 2 to 85 parts by mass, based on 100 parts by mass of the total amount of the composition, and the hydrocarbon oil and the at least one saturated fatty acid are in the form of a crosslinked gel. 13 . The composition of claim 12 , wherein the wet-sensitive colorant composition further comprises a pH indicator. 14 . The composition of claim 12 , wherein the wet-sensitive colorant composition further comprises a surfactant. 15 . The composition of claim 14 , wherein the surfactant is a nonionic surfactant. 16 . The composition of claim 14 , wherein the surfactant is an anionic surfactant. 17 . The composition of claim 12 , wherein the hydrocarbon oil is present in an amount of from 5 to 90 parts by mass, based on 100 parts by mass of the total amount of the composition. 18 . The composition of claim 12 , wherein the wet-sensitive colorant composition is present in an amount of from 0.05 to 5 parts by mass, based on 100 parts by mass of the total amount of the composition. 19 . The composition of claim 12 , further comprising a rosin-based tackifier resin.
