Liquid Soap or Bar Soap?

Liquid soap or bar soap

Do you prefer the look and feel of a solid bar of creamy soap? Or do you enjoy dispensing a pearl of hand wash that transforms into a luxurious lather? We’ve just launched our first liquid hand wash, as part of the Royal Botanic Gardens, Kew Collection. So now feels like the perfect time to explore liquid soap or bar soap. 

We’ve taken a look at both the formulation and the main benefits of both liquid and bar soap, to help you decide which is right for you.

How do you make liquid vs. bar soap?

Soap is a very clever substance. It’s essentially made by mixing a fat or oil with an alkali substance known as lye. This triggers a molecular reaction called saponification. In bar soapmaking, the lye used is sodium hydroxide, and in liquid soap, it’s usually potassium hydroxide – this makes the end product more water-soluble. Saponification transforms the lye so that there’s little or none of it left in its pure form in the final product.

Washing with Soap

Which type of soap is more softening?

Both our liquid and bar soaps are scented with one of our exquisite fragrances and benefit from added softening ingredients to ensure your hands feel cared for.

Our bar soaps are enhanced with rich shea butter, which deeply moisturises and protects the skin.

Our new hand washes contain aloe vera and vitamin E to leave your hands feeling clean, pampered and nourished.

What soap should I use for shared or public spaces?

We get asked about this a lot. Our team feel that it depends on the individual, and where the soap will be placed. We had the hospitality industry firmly in mind when we developed our new hand washes because we understand the growing demand for a product that feels ultra-hygienic, is a joy to use and looks striking on the sink. 

When it comes to busy homes, it depends on what your preference is. Experts reassure us that a solid bar of soap is equally as hygienic as liquid hand wash once lathered. But for your guest bathroom or downstairs toilet, you may prefer the convenience of a pump-action bottle.

Is the packaging eco conscious?

The obvious perks of bar soap are that it just needs a paper wrap to keep it safe. This is why we’ve meticulously developed the packaging for our hand washes, using amber-hued post-consumer resin (PCR), that is also able to be recycled again! PCR is made from a mix of previously recycled plastics and is a fantastic alternative to virgin plastic. 

The labels for our Kew Hand Wash Collection have been designed by our in-house illustrator, inspired by the plants in the gardens at Kew, and in the style of heritage botanical illustrations. These generously proportioned bottles will look beautiful when displayed in your bathrooms or ensuite, making handwashing feel like an absolute treat.
