Enhancing the efficacy of feminine hygiene sanitary napkins by developing a super absorbent polymer based on methyl methacrylate and methacrylic acid

Abstract

Super absorbent polymer based on methyl methacrylate (MMA), methacrylic acid (MAA) has been prepared during the present work for coating the top layer of feminine sanitary napkins. Synthesized polymers were coated on the needly punched cotton and adjusted as the top layer of the sanitary napkins, which has been prepared. The samples were evaluated by means of absorbency capacity, rewet back, strike through, and pH by the comparative study with commercially available sanitary napkin. The most suitable ratio of monomers (60 g MMA, and 40 g MAA) for synthesizing polymer was suggested. Absorbency capacity of the said ratio is competing with commercial sample with 63.68 g absorbent capacity. Specially, pH of prepared polymers suggested the acidic value and those are more preferable for maintaining the acidic pH of vagina at the menstrual time. Present work suggests the polymer, which can be utilize for coating the feminine napkin by the comparative result suggested by absorbency capacity, rewet back, strike through, and pH.
