Not only are incontinence pads expensive, nothing says old like having to buy them instead of menstrual pads. Pads are not something you want to talk about in the first place, so when you spot the date next to the UPC, you\u2019re not going to head to the pharmacy and ask if that\u2019s an expiration date, are you? <\/p>\n\n\n\n
Incontinence pads do expire. Manufacturers add expiration dates for two reasons. First, most pads consist of a combination of natural and human-made ingredients. Second, there is a risk of fungus or bacteria growing on incontinence pads since the packaging is not airtight. <\/strong><\/p>\n\n\n\n
If you don\u2019t want to talk about incontinence, you\u2019re not alone. Only 45% of women who suffer from incontinence<\/a> ever seek treatment for it. In this post, you will learn why incontinence pads expire and whether it is safe to use pads past their expiration date. <\/p>\n\n\n\n
In this post, we'll cover:<\/p>\n
Incontinence pads consist of a combination of textiles and polymers. The textiles will be woven fabric, cotton, or wood by-products, while the polymers will be human-made products, including various kinds of plastics and other resins. <\/p>\n\n\n\n
The polymers used in incontinence pads are designed for their ability to absorb liquids. Once water encounters these polymer crystals, they turn into a gel to absorb the urine. Because of their ability to absorb large quantities of fluids quickly, they are used in incontinence pads but not most menstrual pads.<\/p>\n\n\n\n
One gram of a superabsorbent can absorb<\/a> up to 500 grams of water, or 500 times its weight. Because of their ability to hold water, similar superabsorbent polymers<\/a> are used in horticulture. They keep water from penetrating underground cables and make the artificial snow you see in movies.<\/p>\n\n\n\n
Superabsorbent polymer crystals are often used in science projects, such as this one from an educational site<\/a>. Another example is this pdf from Evonik<\/a>, a significant producer of superabsorbents. <\/p>\n\n\n\n
