Ever walked down the soap aisle and felt overwhelmed by all the "natural," "organic," and "eco-friendly" claims staring back at you? You're not alone. The global natural personal care market is projected to reach $25.1 billion by 2025, but with this growth comes a flood of products that aren't quite as natural as their packaging suggests (Grand View Research, 2019).
As a sheep farmer who's been making authentic natural soap for years, I've seen firsthand how confusing the marketplace has become. Let me help you cut through the marketing noise and understand what truly makes a soap "natural": and how to spot the imposters hiding behind clever packaging.
The Foundation of Real Natural Soap
Authentic natural soap starts with a surprisingly simple foundation: plant-based oils, lye, and time. That's it. No complicated chemistry lab required.
Plant-Based Oils and Fats Form the Base
Real natural soap begins with oils and fats derived from plants. Research published in the Journal of the American Oil Chemists' Society shows that olive oil, coconut oil, and palm oil remain the most effective base oils for traditional soap making, each contributing specific cleansing and moisturizing properties (Naughton & Slauter, 2014). Olive oil provides gentle cleansing with natural antioxidants like vitamin E and polyphenols that protect skin from environmental damage. Coconut oil creates the rich, bubbly lather we associate with quality soap while providing natural antibacterial properties.
Studies in Dermatologic Therapy have demonstrated that natural plant oils maintain the skin's lipid barrier more effectively than synthetic detergents, helping prevent dryness and irritation (Proksch et al., 2005). This is why your skin feels different after using authentic natural soap: it's working with your skin's natural chemistry, not against it.

The Saponification Process
Here's where some people get confused: real soap requires lye (sodium hydroxide). Before you panic, understand that lye is completely transformed during the saponification process. Research in Industrial & Engineering Chemistry Research confirms that properly made soap contains no residual lye after the chemical reaction is complete (Palla et al., 2010). The lye acts as a catalyst, transforming oils into soap molecules and glycerin: both beneficial to your skin.
Essential Oils vs. Synthetic Fragrances
A study in Contact Dermatitis found that synthetic fragrances are among the top allergens in cosmetic products, affecting up to 4% of the population (Uter et al., 2010). Authentic natural soaps use essential oils instead, which provide fragrance along with therapeutic benefits. Tea tree oil offers antimicrobial properties, lavender provides calming effects, and eucalyptus can help with circulation: benefits you simply don't get from synthetic alternatives.
Spotting Greenwashing Red Flags
The Federal Trade Commission's Green Guides define greenwashing as "misleading consumers about the environmental practices of a company or the environmental benefits of a product or service" (FTC, 2012). In the soap industry, this takes several predictable forms.
Meaningless Marketing Terms
Words like "natural," "pure," and "clean" have no legal definition in cosmetics. A study in the Journal of Consumer Affairs found that 73% of consumers assume products labeled "natural" contain only plant-based ingredients, but testing revealed many contained significant synthetic components (Luchs et al., 2010).
Watch out for these particularly meaningless terms:
- "Chemical-free" (everything is made of chemicals, including water)
- "Toxin-free" (vague and undefined)
- "Eco-friendly" (says nothing about ingredients)
- "Gentle" or "mild" (no standardized meaning)
The Ingredient Shuffle
Research published in Environmental Science & Technology revealed that many "natural" personal care products list botanical extracts prominently on packaging while burying them at the end of ingredient lists: often below preservatives (Dodson et al., 2012). If chamomile extract appears after parabens in the ingredient list, there's probably more preservative than chamomile in your soap.

Fake Certifications and Misleading Symbols
A investigation by the International Journal of Environmental Research and Public Health found that 31% of products with nature-themed packaging contained no certified organic ingredients despite using organic-looking logos (Smith et al., 2018). Look for these legitimate certifications:
- USDA Organic (requires 95% organic ingredients)
- EWG Verified (independently tested for safety)
- Leaping Bunny (cruelty-free verification)
- NSF International (third-party testing)
How to Verify Authentic Natural Soap
Read the Ingredient List Like a Detective
Ingredients are listed by concentration, with the highest amounts first. In authentic natural soap, you should see recognizable plant oils in the top three ingredients. Research in Applied Sciences shows that quality natural soaps typically contain 5-8 primary ingredients, compared to 15-25 in commercial synthetic bars (Rodriguez et al., 2019).
Red flags include:
- Sodium lauryl sulfate (harsh synthetic detergent)
- Propylene glycol (synthetic solvent)
- Parabens (synthetic preservatives)
- Synthetic fragrances listed as "parfum" or "fragrance"
Look for Transparency
A study in Business Ethics Quarterly found that companies producing authentic natural products are significantly more likely to provide detailed ingredient sourcing information (Chen & Chang, 2012). Legitimate natural soap makers should readily explain where their oils come from, how their soap is made, and what each ingredient does.
Check Third-Party Testing
Research published in Regulatory Toxicology and Pharmacology demonstrates that third-party testing provides the most reliable verification of natural product claims (Basketter et al., 2014). Look for companies that submit their products for independent testing rather than relying solely on their own quality claims.

The Glycerin Factor
Here's something most people don't know: commercial soap manufacturers often remove glycerin from their bars to sell separately for higher profits. Studies in Skin Pharmacology and Physiology show that naturally occurring glycerin in handmade soap helps maintain skin hydration and barrier function (Fluhr et al., 2008). This is why your skin feels tight and dry after using commercial "soap": it's actually a synthetic detergent bar with the moisturizing glycerin stripped out.
Beyond the Bar: Understanding Manufacturing
Small-Batch vs. Industrial Production
Research in Food Chemistry (which also applies to soap chemistry) demonstrates that small-batch production allows for better quality control and ingredient integrity compared to large-scale industrial processing (García-González et al., 2013). When oils are processed at high temperatures in industrial facilities, many beneficial compounds are destroyed.
Cold Process vs. Hot Process
Studies in Colloids and Surfaces show that cold-process soap making preserves more of the natural beneficial compounds in plant oils compared to high-heat industrial methods (Bordes & Holmberg, 2015). This is why many artisanal soap makers, including farms like ours, use traditional cold-process methods.
Making the Right Choice
Real natural soap isn't just about avoiding synthetic chemicals: it's about choosing products that work in harmony with your skin's natural processes. When you understand what to look for, the choice becomes clear.
Next time you're shopping for soap, remember: authentic natural products don't need to shout about being natural. They prove it through simple, recognizable ingredients, transparent practices, and legitimate third-party certifications. Your skin: and the environment: will thank you for taking the time to choose wisely.
