You May Not Be Looking for Unscented Soap—You May Be Trying to Avoid “Fragrance”
Searches for unscented soap and fragrance-free soap are far larger than searches for fragrance-oil-free soap, but those terms don't necessarily mean the same thing. A product labeled “unscented” may still contain fragrance ingredients used to mask the natural odor of the formula. And under U.S. cosmetic labeling rules, complex fragrance mixtures can often appear on an ingredient list simply as “fragrance” or “parfum,” rather than disclosing each component individually.
So if strong artificial scents are what you're trying to avoid, the better question may not be “Does this soap have a scent?” but “What was used to create that scent?” At Bogue Milk Soap, our scented soaps get their botanical aromas from pure essential oils rather than synthetic fragrance oils. Our No.5 "Walk in Solitude" unscented goat milk soap is the exception for those who prefer a bar with no added scent at all.
That distinction—essential oils vs. fragrance oils—is where reading the ingredient label becomes important.
Fragrance isn't limited to soap. Shampoo, conditioner, body lotion and other everyday bath products frequently use added fragrance to create a strong or lasting scent. If you're searching for “unscented” bath products because heavily fragranced products bother you, it may be worth looking more closely at the ingredient label. The distinction you're actually looking for may be essential oils vs. added fragrance—not simply scented vs. unscented.
Essential Oils vs. Fragrance Oils: What's the Difference?
Fragrance Isn't Just in Soap
Added fragrance is found throughout the bath and body aisle, including shampoos, conditioners, lotions, body washes and other products used every day. For people who are sensitive to heavily fragranced products, that exposure can extend well beyond the soap dish. In a U.S. population study of fragranced consumer products, participants reported adverse effects including migraine headaches, respiratory symptoms and skin problems following fragrance exposure. The study included personal-care products such as soaps, shampoos and lotions among the sources of fragranced-product exposure. Read the published study on PubMed Central.

Why Can Fragrance Be So Hard to Identify on an Ingredient Label?
Reading the ingredient list should tell you what's in a bath product, but fragrance is an unusual exception. Under U.S. cosmetic labeling rules, the individual ingredients that make up a fragrance mixture do not always have to be listed separately. Instead, the entire mixture may appear on the label simply as “fragrance” or “parfum.” The FDA explains that fragrance formulas can be complex mixtures containing natural and synthetic ingredients and are often treated as proprietary formulations. This means a shopper looking at a shampoo, conditioner, lotion or other cosmetic may not be able to determine every ingredient used to create its scent from the label alone. Read the FDA guidance on fragrance ingredients and cosmetic labeling.

That matters because fragrance isn't necessarily a single ingredient. A 2024 scientific review of fragrance contact allergy describes fragrance mixtures as formulations containing multiple chemical substances and notes that more than 150 fragrance materials have been confirmed through laboratory or clinical research to have the ability to sensitize skin. The review also points to the complexity of fragrance mixtures as one reason identifying individual fragrance exposures can be difficult. Read the 2024 review published in Acta Dermato-Venereologica.
This is one reason we believe the words on the front of a bottle or bar tell only part of the story. Terms such as handmade, goat milk, botanical or natural don't necessarily tell you what was used to create the scent. Turn the product around and look at the ingredient list: does it simply say fragrance or parfum, or does it identify the botanical oils used to scent the product?
Why Do Some Fragranced Products Cause Headaches?
If you've ever opened a strongly scented soap, shampoo or lotion and felt a headache coming on, you're not alone. In an international population study of 4,435 adults across the United States, Australia, the United Kingdom and Sweden, 12.6% reported migraine headaches when exposed to fragranced consumer products. In the United States, that figure was 15.7%. Read the international population study.
That's worth remembering when comparing products described as natural, handmade, botanical or goat milk. Those words don't tell you what creates the scent. Two handmade goat milk soaps can sit side by side while one is scented with a formulated fragrance oil and the other identifies the plant essential oils used to create its aroma.
Essential Oils vs. Fragrance Oils: Read Beyond the Front Label
Ultimately, that's the distinction we think matters. A beautiful scent name (or words like natural and handmade) doesn't tell you how a product was scented. Turn it around. If the ingredient list says simply fragrance or parfum, the individual components of that fragrance mixture may not be disclosed. If it names lavender, rosemary, bergamot, frankincense or other essential oils, you can see the botanical ingredients being used to create the scent.
At Bogue Milk Soap, we choose the second approach. Our scented goat milk soaps and bath products get their aromas from pure essential oils rather than synthetic fragrance oils. So whether you're comparing essential oils vs. fragrance oils, searching for unscented soap, or simply trying to understand what's creating the scent in a product, start with the ingredient list—not the fragrance name on the front.
