Abstract

Abstract The present invention relates to absorbent articles which provide improved protection against skin overhydration. A particularly preferred embodiment of an absorbent article of the present invention comprises a body contacting surface having a skin care composition thereon that, when at least a portion of the composition is transferred to a wearer's skin by normal body motion or body heat, the material is effective in providing a skin condition benefit and a liquid impermeable, breathable backsheet having a mass vapor transmission rate value (MVTR) of at least about 1300 g/m2/24 hr and an absorbent core having a post acquisition collagen rewet method value (PACORM) with a PACORM:MVTR ratio is less than 0.05 mg/(g/m2/24 hr).

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 139 words
An absorbent article for absorption of bodily fluids deposited by a wearer, said absorbent article comprising: a. a body contacting surface having a skin care composition that is transferred from said body contacting surface to said wearer's skin by contact, normal wearer motion and/or body heat at a level effective in providing a skin condition benefit to said wearer's skin; b. a liquid impermeable backsheet, wherein said backsheet comprises a first zone having a mass vapor transmission rate value of at least about 1300 g/m 2 /24 hr; and c. an absorbent core positioned between said body contacting surface and said backsheet, wherein said absorbent core has a post acquisition collagen rewet value and the ratio of said post acquisition collagen rewet value to said mass vapor transmission rate value is less than about 0.05 mg/(g/m 2 /24 hr).
Claim 2
Dependent Claim 139 words
An absorbent article for absorption of bodily fluids deposited by a wearer, said absorbent article comprising: a. a body contacting surface having a skin care composition that is transferred from said body contacting surface to said wearer's skin by contact, normal wearer motion and/or body heat at a level effective in providing a skin condition benefit to said wearer's skin; b. a liquid impermeable backsheet, wherein said backsheet comprises a first zone having a mass vapor transmission rate value of at least about 1300 g/m 2 /24 hr; and c. an absorbent core positioned between said body contacting surface and said backsheet, wherein said absorbent core has a post acquisition collagen rewet value and the ratio of said post acquisition collagen rewet value to said mass vapor transmission rate value is less than about 0.05 mg/(g/m 2 /24 hr).
Claim 3
Dependent Claim 42 words
An absorbent article according to claim 1 wherein said backsheet comprises two or more zones, and at least one of the remaining zones has a mass vapor transmission rate value greater than said mass vapor transmission rate value in said first zone.
Claim 4
Dependent Claim 15 words
An absorbent article according to claim 1 wherein said body contacting surface comprises a topsheet.
Claim 5
Dependent Claim 17 words
An absorbent article according to claim 1 wherein said body contacting surface comprises an elastic leg cuff.
Claim 6
Dependent Claim 17 words
An absorbent article according to claim 1 wherein said body contacting surface comprises an elastic waist feature.
Claim 7
Dependent Claim 37 words
An absorbent article according to claim 1 wherein at least about 0.07 mg/cm 2 of said skin care composition is transferred from said body contacting surface to said wearer's skin by normal wearer motion and/or body heat.
Claim 8
Dependent Claim 37 words
An absorbent article according to claim 1 wherein said absorbent article has a normalized integrated vapor flux and said skin care composition provides a reduction in said normalized integrated vapor flux of at least about 5 percent.
Claim 9
Dependent Claim 27 words
An absorbent article according to claim 7 wherein said skin care composition provides a reduction in said normalized integrated vapor flux of at least about 27 percent.
Claim 10
Dependent Claim 43 words
An absorbent article according to claim 1 wherein said absorbent core has a post acquisition collagen rewet value and said skin care composition causes said post acquisition collagen rewet value of said absorbent core to be reduced by at least about 35 mg.
Claim 11
Dependent Claim 19 words
An absorbent article according to claim 1 wherein said ratio is less than about 0.04 mg/(g/m 2 /24 hr).
Claim 12
Dependent Claim 19 words
An absorbent article according to claim 1 wherein said ratio is less than about 0.03 mg/(g/m 2 /24 hr).
Claim 13
Dependent Claim 19 words
An absorbent article according to claim 1 wherein said ratio is less than about 0.019 mg/(g/m 2 /24 hr).

Claim 15
Dependent Claim 138 words
An absorbent article for absorption of bodily fluids deposited by a wearer, said absorbent article comprising: a. a liquid permeable topsheet having a lotion disposed on a body contacting surface thereof, wherein said lotion is transferred from said body contacting surface to said wearer's skin by contact, normal wearer motion and/or body heat at a level for reducing skin overhydration; b. a liquid impermeable backsheet, wherein said backsheet comprises a first zone having a mass vapor transmission rate value of at least about 1300 g/m 2 /24 hr; and c. an absorbent core positioned between said body contacting surface and said backsheet; wherein said absorbent core has a post acquisition collagen rewet value and ratio of said post acquisition collagen rewet value to said mass vapor transmission rate value is less than about 0.05 mg/(g/m 2 /24 hr).
Claim 16
Dependent Claim 138 words
An absorbent article for absorption of bodily fluids deposited by a wearer, said absorbent article comprising: a. a liquid permeable topsheet having a lotion disposed on a body contacting surface thereof, wherein said lotion is transferred from said body contacting surface to said wearer's skin by contact, normal wearer motion and/or body heat at a level for reducing skin overhydration; b. a liquid impermeable backsheet, wherein said backsheet comprises a first zone having a mass vapor transmission rate value of at least about 1300 g/m 2 /24 hr; and c. an absorbent core positioned between said body contacting surface and said backsheet; wherein said absorbent core has a post acquisition collagen rewet value and ratio of said post acquisition collagen rewet value to said mass vapor transmission rate value is less than about 0.05 mg/(g/m 2 /24 hr).
