Solid Soap: A New Wave of Popularity

Solid Soap: A New Wave of Popularity

Why does the demand for solid soap and related products (such as shampoo bars, facial soaps, and shaving soaps) continue to grow year after year?

1. Water Conservation
   Liquid cosmetic products are made up of 70–90% water, and clean water is becoming an increasingly scarce and valuable resource. According to UN estimates, 1.8 billion people are already facing water shortages.
2. Reduced Transportation and Storage Costs
   By removing water from the formulation, manufacturers significantly reduce the volume and weight of their products, which lowers transportation costs and decreases their carbon footprint. For consumers, solid soap is travel-friendly—lightweight and not subject to airline liquid restrictions.
3. Packaging Reduction
   Liquid and semi-liquid products require large amounts of plastic for leak-proof packaging. Unfortunately, the cosmetics industry is one of the major contributors to single-use plastic waste, much of which ends up in landfills and can take hundreds of years to decompose. Water-free cosmetics align better with zero-waste principles, as they require minimal packaging and can be wrapped in biodegradable materials like paper, cardboard, wood, or natural fibers.
4. Biological Safety
   Bacteria cannot thrive in dry environments, so preservatives—which can increase costs and potentially irritate the skin or disrupt its natural microbiome—are not necessary in solid formulations.
5. Versatility and Enhanced User Experience
   While soap’s primary function is to cleanse the hands and body, high-quality, naturally scented soap can elevate your self-care routine. For instance, foam massage—a hallmark of a traditional Turkish hammam—can be recreated using a solid soap bar, a bowl of water, and a firm wash mitt.

Solid soap is also beneficial for facial care. Start by lathering the soap in your palms for several minutes (ideally using a mesh washcloth) until a dense, fluffy foam forms. Apply the foam to your face and perform a gentle patting massage—your fingers should only press on the foam, not the skin. Rinse thoroughly with warm water and pat your face dry with a soft paper towel. Follow with your usual skincare routine: toner, serum, and cream. You’ll notice how easily your products absorb into the freshly cleansed skin. This technique offers a gentle lymphatic drainage effect, leaving pores tightened and the skin glowing. It’s especially beneficial for those with normal, oily, or thick skin with enlarged pores.

Soaps containing pure essential oils also offer aromatherapeutic benefits, helping to set the mood. For example, lemon or grapefruit scents invigorate and awaken, while lavender or Valeriana celtica (speick) promote evening relaxation.

Here’s a timeless tip: place a piece of fragrant soap in your wardrobe to subtly scent your clothes. Soaps with lavender or lemongrass essential oils are ideal, as they also help repel moths.

When choosing solid soap, always check the ingredient list and sourcing. The best soaps are made with sustainably sourced palm or coconut oil, ensuring no harm to untouched tropical forests. Premium formulations may also include extra-virgin olive oil, organic essential oils, plant-based glycerin, and natural additives like milk, honey, or beeswax.
