The present invention relates a method for improving skin condition by repeatedly applying lotion-treated absorbent articles to a wearer. When applied with sufficient frequency, the skin in the area covered by lotion-treated absorbent articles shows improvement in skin smoothness, relative to skin covered by untreated absorbent articles that do not comprise a skin care composition. The present invention also relates to methods for assessing skin smoothness in the area covered by an absorbent article.

A tampon according to claim 13 or 16 wherein said wetting agent is selected from the group consisting of glycerol, polyethylene glycol (PEG), polypropylene glycol (PPG) and surfactants with an HLB ranging from 10 to 18. 19. A formulation according to claim 1 further comprising an anti-inflammatory agent. 20. A delivery system according to claim 7 further comprising an anti-inflammatory agent. 21. A tampon according to claim 13 or 16 further comprising an anti-inflammatory agent. 22. A delivery system according to claim 6 wherein said lactide is DL-lactide or L-lactide. 23. A tampon according to claim 13 wherein said lactide is DL-lactide or L-lactide. vatives or salts thereof. aim 1, wherein the volume increments withdrawn from the reaction vessel are analyzed for concentration of reactants and product. 18. The method of claim 1, wherein the volume increments withdrawn from the reaction vessel are pooled and subsequently analyzed to provide cumulative data. 19. The method of claim 1, wherein the volume increments are withdrawn from the reaction vessel by positioning a probe at a predetermined level within the reaction vessel and withdrawing reactor fluid until no further fluid can be withdrawn by the probe at the predetermined level. 20. The method of claim 1, wherein after the reaction is allowed to proceed for a time interval the volume increments are withdrawn and added simultaneously. 21. The method of claim 1, wherein after the reaction is allowed to proceed for a time interval volume increments are added before being withdrawn. 22. A method of producing a chemical reaction between phenol and acetone to produce bisphenol A in a batch reactor emulating the conditions of a continuous flow reactor by incremental flow, the method comprising the steps of: a) providing a reaction vessel and reactants; b) placing at least one of the reactants in the reaction vessel; c) allowing the reaction to proceed for a time interval; d) withdrawing a volume increment of the reaction mixture comprising at least one of the reactants from the reaction vessel; e) adding a volume increment of at least one of the reactants to the reaction vessel; and f) selecting the time intervals and the volume increments to obtain a desired space velocity. 23. The method of claim 22, wherein the added volume increment comprises phenol. 24. The method of claim 22, wherein the added volume increment comprises acetone. 25. The method of claim 22, wherein the reaction vessel further contains an ion exchange resin. 26. The method of claim 22, wherein the added volume increment further comprises a reaction promoter. 27. The method of claim 22, further comprising the step of selecting the reactor residence time of at least one of the reactants by controlling the time interval between additions. 28. The method of claim 22, further comprising the step of selecting the reactor residence time of at least one of the reactants by controlling the size of the volume increments added and withdrawn from the reactor. 29. The method of claim 22, wherein the desired space velocity is obtained by selecting the time intervals and the volume increments in accordance with the following relationship: 30. The method of claim 22, further comprising the steps of: adding a sample volume increment, the volume increment being larger than the volume increment added in step d); withdrawing volume sub-increments from the reaction mixture at appropriate subintervals within the time interval, such that the sum of the volume sub-increments is equivalent to the sample volume increment; and analyzing the volume sub-increments to provide data regarding the concentration gradient during a time interval. 31. The method of claim 22, wherein the size of the volume increments are chosen to minimize concentration gradients between time intervals. 32. The method of claim 22, wherein the volume increments withdrawn from the reaction vessel are analyzed for concentration of reactants and product. 33. The method of claim 22, wherein the volume increments withdrawn from the reaction vessel are pooled and subsequently analyzed to provide cumulative data. 34. The method of claim 22, wherein the volume increments are withdrawn from the reaction vessel by positioning a probe at a predetermined level within the reaction vessel and withdrawing reactor fluid until no further fluid can be withdrawn by the probe at the predetermined level. 35.
