If you prefer to wear a panty liner each day or just during your period, or when travelling, it makes sense to choose a panty liner that is made only from plastic-free, non-chlorine bleached natural materials. Many gynaecologists have advised women with sensitive skin to use natracare products to reduce their contact with chlorine-bleached materials, and products containing synthetics and super absorbents made from petrochemicals. We never add fragrances to any of our liners. Natracare chemical free panty liners are high quality products made from only pure and natural materials that are derived from plant cellulose. They are not chlorine bleached and are free of rayon, plastics and other similar synthetic materials that have a negative impact on our environment. The curved liner is more of an hourglass shape for a slimmer fit.
