Soap Types and Sustainability Compared

Bar soap is a popular choice for its simplicity and minimal packaging, but it's often made with harsh chemicals like sodium lauryl sulfate, which can be detrimental to the environment.

Liquid soap, on the other hand, is often formulated with more eco-friendly ingredients and comes in refillable containers, reducing waste and the need for single-use plastics.

Some soap types are made with natural ingredients like coconut oil and olive oil, which are biodegradable and gentle on the skin.

These natural ingredients also make soap more sustainable, as they can be sourced locally and require less processing, reducing the carbon footprint of the soap-making process.

The history of soap dates back thousands of years, with the earliest recorded evidence of soap-like materials dating back to around 2800 BC in ancient Babylon.

The ancient Babylonians discovered that by heating a mixture of oil and wood ash, they could create a soap-like substance used for washing woolen clothing.

A Sumerian clay tablet from around 2500 BC contains a formula for making this soap-like substance, showcasing the ancient civilization's understanding of chemical reactions.

The Ebers papyrus from Egypt, written around 1550 BC, indicates that the ancient Egyptians used a soap-like product as a medicine and created it by combining animal fats or vegetable oils with trona, a soda ash substance.

This soap-like product was also used in the preparation of wool for weaving, highlighting the importance of cleanliness in ancient Egyptian culture.

In the reign of Nabonidus, a recipe for a soap-like substance consisted of uhulu ashes, cypress oil, and sesame seed oil, specifically for washing the stones used by servant girls.

These ancient civilizations' use of soap-like substances for various purposes demonstrates the significance of cleanliness and hygiene in their daily lives.

Our soap ingredients are carefully selected to ensure they're not only effective, but also gentle on the skin.

We use a combination of organic oils, including coconut oil, which gives our soaps their copious, thick lather.

Coconut oil is also Regenerative Organic Certified and fair trade, which is a great way to support sustainable farming practices.

Our soaps also contain palm oil, which is another key ingredient that helps create a rich lather.

Sodium hydroxide, or lye, is used to saponify the oils into soap and glycerin. Don't worry, none of it remains in the final product.

We also add a touch of mentha arvensis and mentha piperita, which give our soaps a refreshing and invigorating scent.

Here's a breakdown of some of the key ingredients:

Soap production involves a process called saponification, where an alkaline solution is used to split fat into its components, resulting in soap and glycerin. This process can be done using various fats and oils, including vegetable and animal sources.

The type of fat used can greatly affect the final product, with different fatty acid contents resulting in distinct feel and properties. For example, soap made from pure olive oil is known for its mildness, while soap made from coconut oil is often firmer.

Here's a breakdown of the fatty acid content of various fats used for soapmaking:

Making soap is an ancient process that's still used today. Early soapmakers likely used ashes and animal fats to create their soap.

Animal fats containing free fatty acids were used by the Celts, which helped to start the soap-making process. This method was used until the end of the Middle Ages.

To make soap, you need to saponify triglycerides, which are vegetable or animal oils and fats. An alkaline solution, often lye, induces saponification, breaking down the triglycerides into salts of fatty acids and glycerin.

Glycerin can be left in the soap product as a softening agent or separated. Handmade soap often uses an excess of fat or coconut oil, known as "superfatting", which makes the soap more skin-friendly.

The type of alkali metal used determines the kind of soap product. Sodium soaps are firm, while potassium soaps are softer or often liquid.

Here are some common fatty acids found in various fats used for soapmaking:

Liquid soap was invented in the nineteenth century, with William Sheppard patenting a liquid version in 1865.

B.J. Johnson developed a soap derived from palm and olive oils in 1898, which became the popular "Palmolive" brand that same year.

This new brand of soap became so popular that B.J. Johnson's company changed its name to Palmolive.

Liquid soaps made cleaning easier, not just for skin, but also for other surfaces like clothing, floors, and bathrooms.

Companies like Pine-Sol and Tide introduced their own liquid soaps in the early 1900s, expanding the convenience of liquid soap.

Toilet soap is a type of soap that's commonly used for household and personal cleaning. It's technically called a toilet soap because it's used for cleaning, and its formula is (RCO2)M, where M is Na (sodium) or K (potassium).

Soap solubilizes particles and grime, making it easy to separate them from the article being cleaned. This is because soap forms micelles, tiny spheres with polar groups on the outside and a lipophilic pocket inside.

Using toilet soap in hard water can be a problem, as it doesn't lather well and instead forms soap scum. This is related to metallic soaps, which are a different type of soap.

Toilet soap can also kill microorganisms by disorganizing their membrane lipid bilayer and denaturing their proteins. This is why it's effective at killing germs when used in hand washing.

Adding compounds like triclosan or triclocarban to toilet soap can make it antibacterial. However, there's some concern that using antibacterial soaps might encourage antimicrobial resistance in microorganisms.
