What Is Goat Milk Soap Made Of?

🐐

Goat Milk

INCI: Caprae Lac

The signature ingredient. Goat milk soap is a gentle, moisturising soap suitable for sensitive skin. It contains naturally occurring fatty acids, including caprylic acid, which can help support the skin's natural moisture barrier. In soap form, goat milk also contributes to a creamy, smooth lather. "Caprae Lac" is simply the Latin name for goat milk.

💧

Water

INCI: Aqua

Water is used during the soap-making process to help combine the oils and other ingredients. Most of the water evaporates as the soap cures, which is why handmade soap bars are firm and long-lasting by the time they reach you.

🌸

Fragrance

INCI: Fragrance

We use fragrance oils to scent our soaps. Each scent, from lavender to eucalyptus to cherry blossom, is chosen for its aroma. Unlike the generic "parfum" found in commercial products (which can contain dozens of undisclosed compounds), our fragrance oils are listed transparently.

Skin-Safe Colour

INCI: CI 77891

The subtle colours in our soap come from cosmetic-grade colourants that are specifically tested and approved for skin contact. CI 77891 is titanium dioxide, one of the most widely used and well-studied cosmetic colourants in the world. It rinses away cleanly and won't stain your skin or bathtub.

The Full INCI List , Decoded

Here's what a typical ingredient label on our goat milk soap looks like, with the everyday name next to each INCI term:

📋 Typical Goat Milk Soap Ingredients

Sodium Olivate , Saponified Olive Oil
Sodium Cocoate , Saponified Coconut Oil
Caprae Lac , Goat Milk
Aqua , Water
Fragrance , Fragrance Oil (varies by scent)
CI 77891 , Titanium Dioxide (Skin-Safe Colour)

Ingredients listed in descending order per Australian cosmetic standards. Exact formulation may vary slightly between scents.

That's it. Seven ingredients. Every single one serves a purpose, and every single one is something you can research and understand. Compare that to a typical commercial soap bar, which may list 15-30 ingredients including synthetic detergents, preservatives, and undisclosed fragrance compounds.

If you can't understand what's in your soap, how can you know whether it's right for your skin? Transparency isn't a marketing feature, it's the bare minimum.

What About "Saponification"?

You'll notice the oils are listed as "Sodium Olivate" and "Sodium Cocoate" rather than just "olive oil" and "coconut oil." That's because they've been through a process called saponification, which is simply the chemical reaction that turns oils into soap.

During saponification, oils are combined with an alkali (sodium hydroxide, also known as lye) to produce soap and a byproduct. The sodium hydroxide is completely consumed in the reaction, none remains in the finished bar. This is why you won't see "sodium hydroxide" on the final ingredient list, even though it's used during production. It's the same process soap makers have used for thousands of years.

What's NOT in Our Soap

Sometimes what a product leaves out is just as important as what it puts in. Here's what you won't find in our goat milk soap:

No SLS or SLES

Sodium lauryl sulphate is a synthetic detergent used in most commercial soaps and body washes to create foam. It's effective, but it can strip your skin's natural oils. Our soap foams naturally through saponification, not synthetic detergents.

No Parabens

Parabens are preservatives used in liquid and cream-based products to prevent bacterial growth. Bar soap doesn't need them, the solid format and low moisture content naturally resist bacteria. No preservatives needed.

No Synthetic Dyes

FD&C and D&C colour codes indicate petroleum-derived synthetic dyes. We use cosmetic-grade, skin-safe colourants instead. They rinse away cleanly and don't stain.

No Undisclosed "Parfum"

In commercial products, the word "parfum" or "fragrance" can hide dozens of undisclosed chemical compounds. Our fragrance oils are a straightforward scent ingredient, what you smell is what you get.

No Plastic Microbeads

Our exfoliating soaps use natural scrubs, coconut shell, walnut shell, and apricot kernel, not plastic microbeads. They're biodegradable and break down naturally after washing.

How to Read Any Soap Label

Whether you're looking at our soap or anyone else's, here are some tips for reading ingredient labels on soap and bath products:

Ingredients Are Listed in Order

By Australian cosmetic standards, ingredients must be listed in descending order of concentration. The first ingredient is present in the highest amount, the last in the lowest. If SLS or "parfum" appears near the top of a commercial soap's list, it's a significant component of the product.

Shorter Is Usually Simpler

A 7-ingredient soap is easier to evaluate than a 25-ingredient one. Fewer ingredients means fewer potential triggers for sensitive skin, and it's easier to identify what might be causing a reaction if one occurs.

Watch for Umbrella Terms

"Parfum," "fragrance," and "natural flavour" can all be umbrella terms covering multiple undisclosed compounds. In the EU, 26 specific allergens must be declared if they're present in fragrance. In Australia, the rules are less detailed. Reading labels carefully is your best defence.

INCI Names Are Universal

INCI (International Nomenclature of Cosmetic Ingredients) is used worldwide, so "Sodium Olivate" means the same thing whether the product comes from Australia, Europe, or the US. If you ever want to look up an ingredient, searching its INCI name will give you reliable information.

It can look intimidating at first, but once you know the common translations (which this article covers), it becomes easy to read.
The base ingredients (olive oil and coconut oil, goat milk, water) remain the same across all our goat milk soaps. What changes between scents is the specific fragrance oil and sometimes the skin-safe colourant used. Each product page lists the exact ingredients for that particular scent, so you can check before purchasing.
Many people with sensitive skin choose goat milk soap because of its short, natural ingredient list and the absence of SLS, synthetic fragrance, and parabens. That said, everyone's skin is different.
