Costa Californica's goal is to eliminate one plastic bottle at a time when possible. However, there are claims against the alternative replacements for plastic bottled body wash. There is this belief that bar soap carry bacteria from one person to the next, since at times people share the same bar of soap. According to recent studies, bacteria levels on previously used bar soaps are slightly higher than on unused soaps, however, there have been no detectable levels of bacteria left on the skin's surface after using the soap used by others . Bar soap users who are still worried about spreading germs can always make sure that each person has his or her own soap.
After careful thought, we have concluded that bar soap remains a greener choice than liquid soap. Because bar soap is typically packaged in paper or cardboard, its packaging materials are not only recyclable, but they also break down more easily in landfills than the plastic packaging liquid soaps, and don't require as large of a carbon footprint and extra polymers to recycle .
At the end of the day, using liquid soap or bar soap is truly a personal choice. More than the method of delivery, the most important thing for you to be aware of is how you react to certain additives, such as fragrances and moisturizers. All of our soaps are made with vegetable oils and do not contain detergents that dry skin. We only recommend to "wash away the day" and not to forget behind the ears!
