What Is Natural Soap? Ingredients, Benefits, and How to Choose the Best One
Walk through the personal care aisle and you'll see the word "natural" everywhere.

But the truth is that the word "natural" has no universal definition in cosmetics. That means two products sitting next to each other on the shelf may both claim to be natural, while being made in completely different ways.
Understanding what makes a soap truly natural requires looking beyond marketing language and focusing on ingredients, formulation, and how the soap is actually made.
The Basics: What Soap Really Is
At its core, soap is created through a process called saponification.
This is the chemical reaction that occurs when oils combine with an alkaline solution, transforming the oils into soap molecules.
Traditional soap typically begins with simple ingredients such as:
- Plant oils
- Mineral ingredients
- Naturally derived fragrance components
When these ingredients react together, they form the cleansing bar we recognize as soap.
This traditional approach has been used for centuries and remains the foundation of many high-quality soaps today.
Why the Word "Natural" Can Be Confusing
Because cosmetic regulations do not strictly define the word natural, brands may use the term in different ways.
For example, some products labeled natural may still contain:
- Synthetic detergents
- Stabilizers
- Artificial colorants
- Complex fragrance blends
In some cases, the product may technically qualify as a cosmetic cleanser rather than traditional soap.
This doesn’t necessarily mean the product is harmful, but it does highlight why understanding ingredient lists matters.
The Ingredients That Define Natural Soap
When people search for natural soap, they are typically looking for products made with simple, recognizable ingredients.
These commonly include:
- Plant oils such as coconut oil, olive oil, or shea butter
- Mineral ingredients used for structure or color
- Natural fragrance components or essential oils
These ingredients allow the soap to perform its cleansing function without requiring complex stabilizers or detergent systems.
Many consumers prefer this simplicity because it aligns with a broader movement toward more transparent personal care products.
How Soapmaking Methods Influence Quality
The way soap is made also plays an important role.
One of the most respected methods is cold process soapmaking.
This traditional technique allows oils to react slowly during saponification and the soap is then cured over several weeks.
Cold process soapmaking is valued because it:
- Preserves the integrity of the oils used
- Naturally produces glycerin
- Requires relatively little energy during production
These characteristics are one reason cold process soaps are often associated with premium natural soap brands.
Natural Soap vs Synthetic Cleansers
Another important distinction is between traditional soap and detergent-based cleansers.
Many liquid cleansers and body washes rely on detergent systems designed to create foam and maintain stability in water-based formulas.
Traditional bar soap, however, is typically concentrated and water-free, which can simplify both the formulation and packaging.
This is one of the reasons many people returning to bar soap describe the experience as simpler and more straightforward.
The Role of Responsible Ingredient Sourcing
Natural soap also involves how ingredients are sourced, not just what ingredients are used.
For example, certain plant oils used in soapmaking - such as palm oil - can be produced responsibly when sourced through certified sustainability programs.
Many soapmakers today rely on programs such as RSPO (Roundtable on Sustainable Palm Oil) to ensure palm oil is produced under environmental and ethical standards.
Responsible sourcing allows natural soap brands to maintain both performance and environmental responsibility.
Packaging Matters Too
Another factor that increasingly defines natural personal care is packaging impact.
Liquid cleansers are commonly packaged in plastic bottles, which contribute significantly to global plastic waste.
Bar soap, by contrast, allows for minimal packaging.
Many modern soap brands now package bar soaps in paper-based packaging systems that reduce reliance on single-use plastics.
This shift toward bar soap has become part of a larger movement toward more thoughtful consumption.
Why Consumers Are Rediscovering Traditional Soap
In recent years, more people have started reconsidering the products they use every day.
They are asking questions like:
- What ingredients am I putting on my skin?
- How was this product made?
- What happens to the packaging after I use it?
For many people, traditional soap provides a simple answer to those questions.
It represents a product that has existed for centuries, built on straightforward chemistry and familiar ingredients.
Inspired by Nature
For some soapmakers, nature is not just an ingredient source - it is the inspiration behind the entire product experience.
At Crate 61, many of our scents are inspired by landscapes that remind us why stewardship matters: alpine forests, cedar groves, and mountain air.
Our National Park Collection celebrates some of North America’s most iconic wilderness areas, translating those environments into scent experiences that bring the outdoors into everyday rituals.
Just as park rangers protect the natural places people love, we believe personal care should respect the natural ingredients and ecosystems that make these products possible.
The Bottom Line
A truly natural soap is defined by more than a label
It reflects the combination of:
- Thoughtfully chosen ingredients
- Traditional soapmaking methods
- Responsible sourcing
- Minimal packaging
When these elements come together, soap becomes more than just a cleansing product.
It becomes a small daily ritual that reflects a deeper respect for both skin and the natural world.
