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
