What is Soap Made Of? Chemical vs. Natural Ingredients (and Soap History!)

Soap is a staple in most households, but how much do you really know about it? From the ingredients to the history, there is a lot to learn about this everyday item. In this detailed soap guide, we will cover everything you need to know about soap, including the low-down on chemical vs. natural ingredients, soap history, and more.

First and foremost, what is soap? At its most basic level, soap is a combination of oils or fats and an alkali, such as lye. These ingredients undergo a chemical reaction called saponification, which creates soap. However, the ingredients used and the process of making soap can vary greatly depending on the type of soap being produced.

When it comes to soap ingredients, there are two main categories: chemical and natural. Chemical ingredients are typically synthetic and can include additives such as fragrances and dyes. Natural ingredients, on the other hand, are derived from plants, animals, or minerals. Both types of ingredients have their pros and cons, and it's important to understand the differences in order to choose the right soap for your needs.

Key Takeaways

  • Soap is made from a combination of oils or fats and an alkali, which undergo a chemical reaction called saponification.
  • Soap ingredients can be categorized as chemical or natural, each with their own advantages and disadvantages.
  • Understanding the differences between chemical and natural soap ingredients can help you choose the right soap for your needs.

What is Soap?

Soap is a substance that has been used for centuries to clean and sanitize the skin. It is made by combining fats or oils with an alkali, such as lye. The chemical reaction that takes place between the fats and the alkali is called saponification, which produces soap.

There are two types of soap: natural and chemical. Natural soaps are made from plant-based ingredients, while chemical soaps are made from synthetic chemicals. Natural soaps are often preferred because they are gentler on the skin and do not contain harsh chemicals.

Soap has a long and interesting history. It is believed that soap was first discovered by the ancient Babylonians around 2800 BC. They found that combining fats with ashes produced a substance that could be used to clean the skin. Soap-making techniques were later refined by the ancient Egyptians, Greeks, and Romans.

Today, soap is used for a variety of purposes, including personal hygiene, cleaning, and even as a decorative item. With so many different types of soap available, it is important to choose the right one for your needs. Whether you prefer natural or chemical soap, there is a wide range of options available to suit your preferences and budget.

Chemical Ingredients in Soap

Saponification Process

The saponification process is a chemical reaction that occurs when oils or fats combine with an alkali, such as sodium hydroxide or potassium hydroxide. This process creates soap and glycerin. The soap is made up of the salts of fatty acids, while the glycerin is a natural byproduct of the reaction.

Common Chemical Ingredients

Many soaps on the market contain chemical ingredients, some of which may be harmful to the skin or the environment. Here are some common chemical ingredients found in soap:

  • Sodium Lauryl Sulfate (SLS): SLS is a surfactant that creates lather and helps to remove dirt and oil from the skin. However, it can be irritating to the skin and may cause dryness or redness.

  • Triclosan: Triclosan is an antibacterial agent that is often added to soaps and other personal care products. However, it has been linked to hormone disruption and may contribute to the development of antibiotic-resistant bacteria.

  • Artificial Fragrances: Many soaps contain artificial fragrances to enhance their scent. However, these fragrances can be made up of hundreds of different chemicals, some of which may be harmful to the skin or the environment.

  • Parabens: Parabens are preservatives that are often added to personal care products to extend their shelf life. However, they have been linked to hormone disruption and may contribute to the development of breast cancer.

Overall, it is important to read the ingredient list on soap products and choose ones that are made with natural, non-toxic ingredients to ensure the best care for your skin and the environment.

Natural Ingredients in Soap

Soap made with natural ingredients has become increasingly popular in recent years due to the benefits they offer. Natural ingredients are gentle on the skin and do not contain any harsh chemicals that can cause irritation or dryness. Here are some of the most commonly used natural ingredients in soap:

Essential Oils

Essential oils are concentrated plant extracts that are used to provide fragrance and therapeutic benefits to soap. They are extracted from various parts of plants, such as flowers, leaves, and roots. Some of the most popular essential oils used in soap making include lavender, peppermint, tea tree, and eucalyptus. Each essential oil has its own unique properties and benefits, such as calming, energizing, or purifying.

Natural Exfoliants

Natural exfoliants are added to soap to help remove dead skin cells and promote healthy skin renewal. Some of the most commonly used natural exfoliants in soap include oatmeal, coffee grounds, and sea salt. These ingredients are gentle on the skin and provide a natural way to exfoliate without the use of harsh chemicals.

Overall, natural ingredients offer a great alternative to traditional soap ingredients and provide numerous benefits for the skin. When selecting a natural soap, be sure to read the label carefully and look for ingredients that are free from synthetic fragrances, preservatives, and other harmful chemicals.

Soap History

Ancient Times

Soap has been around for thousands of years and was first created by ancient civilizations such as the Babylonians, Egyptians, and Greeks. They used a mixture of animal fat and ashes to create a soap-like substance that was used for cleaning and medicinal purposes.

The ancient Romans also used soap, but they made it with a mixture of tallow and ashes. They were the first to add fragrances to soap, making it a more enjoyable experience to use.

Modern Soap

In the 19th century, soap making became more industrialized and the process was refined. Instead of using animal fat, soap makers began using vegetable oils such as palm, coconut, and olive oil. They also started using lye, a strong alkaline solution, to create a more consistent and effective soap.

Today, there are two main types of soap: chemical and natural. Chemical soaps are made with synthetic ingredients and can be harsh on the skin. Natural soaps, on the other hand, are made with plant-based ingredients and are gentler on the skin.

Soap making has come a long way since its ancient beginnings, but the basic process of mixing fats or oils with an alkaline solution remains the same. Whether you prefer chemical or natural soap, there are plenty of options available to suit your needs.

Chemical vs. Natural Soap

Soap can be made using either chemical or natural ingredients. Chemical soaps are usually made using synthetic ingredients, while natural soaps are made using plant-based ingredients.

Chemical soaps often contain harsh chemicals such as sodium lauryl sulfate, which can strip the skin of its natural oils and cause irritation. On the other hand, natural soaps are made using ingredients such as coconut oil, olive oil, and shea butter, which are gentle on the skin and provide nourishment.

One advantage of chemical soaps is that they often have a longer shelf life than natural soaps. However, natural soaps are better for the environment, as they are biodegradable and do not contain harmful chemicals.

When choosing between chemical and natural soap, it is important to consider your skin type and any sensitivities you may have. If you have sensitive skin, natural soap may be a better choice as it is less likely to cause irritation.

Overall, both chemical and natural soaps have their pros and cons. It is up to the individual to decide which type of soap is best for their needs.

Environmental Impact of Soap

Soap has a significant environmental impact, both in terms of its production and disposal. Here are some key factors to consider:

Chemical Ingredients

Many commercial soaps contain synthetic chemicals that can be harmful to the environment. For example, some surfactants used in soap production can be toxic to aquatic life. Additionally, the production of these chemicals can generate pollution and contribute to climate change.

Natural Ingredients

Soap made with natural ingredients, such as vegetable oils and essential oils, can be a more environmentally friendly option. However, it's important to note that even natural ingredients can have an impact on the environment if they are not sustainably sourced or if they are overused.


The packaging of soap can also have an environmental impact. Plastic packaging, for example, can contribute to pollution and take hundreds of years to decompose. Choosing soap that comes in minimal or recyclable packaging can help reduce this impact.


When soap is washed down the drain, it can have an impact on the environment. Chemicals in soap can harm aquatic life, and excess soap can contribute to water pollution. Choosing biodegradable soap and using it sparingly can help reduce this impact.

Overall, the environmental impact of soap depends on a variety of factors, from the ingredients used to the way it is produced and disposed of. By choosing natural, sustainably sourced soap and using it responsibly, consumers can help reduce their impact on the environment.

How to Choose the Right Soap

Choosing the right soap can be a daunting task, especially with the wide variety of options available in the market. Here are some tips to help you choose the right soap for your needs:

  1. Consider your skin type: Different skin types have different needs. If you have dry skin, look for soaps that contain moisturizing ingredients such as glycerin, shea butter, or coconut oil. If you have oily skin, look for soaps that contain ingredients such as tea tree oil or charcoal that can help absorb excess oil.

  2. Check the ingredients: It is important to read the label and understand the ingredients used in the soap. Avoid soaps that contain harsh chemicals such as sulfates, parabens, and phthalates. Instead, look for soaps that use natural ingredients such as essential oils, herbs, and plant extracts.

  3. Consider the scent: Soap comes in a variety of scents, from floral to fruity to earthy. Choose a scent that you enjoy and that suits your personality.

  4. Look for eco-friendly options: If you are concerned about the environment, look for soaps that are made with sustainable ingredients and packaging.

By considering these factors, you can choose a soap that not only cleans your skin but also meets your individual needs.
