Natural hand soap ingredients vs. toxic sulfates and dyes

By Sara Niec Carnahan, Founder, Sara N.C. Beauty January 5, 2023

If there’s one thing we’re all too familiar with nowadays, it’s handwashing. Whether it’s for germ-killing or removing remnants after cooling, the importance of hand soap has not gone unnoticed. But with dry skin abound, we have to wonder: are our go-to sources making our hands happy?

Many conventional hand soaps contain irritating ingredients that can quickly deplete hands of their protective moisture barrier. This could lead to painful, cracked hands and a pathway for infections. We’re identifying the best natural hand soap ingredients, and uncovering the dirty secrets of what we should avoid.

Why It’s Important to Check All Forms of Hand Wash

Routinely washing your hands is about as important as breathing these days. We’ve become so programmed to wash-wash-wash that we may have overlooked what’s really in those hand soaps we picked up from Target. When I say ‘hand soap’ I’m talking liquid, foam, and bar soap.

When looking at long-term use, certain hand soap ingredients could create or worsen skin irritations in hard-working hands. It’s time to lather up a few hand soap ingredients that can keep hands soft, happy, and healthy.

The Pros and Cons of Hand Soap Ingredients

With plenty of different hand soaps on the market, it can be a slippery slope to decide which one is best for your skin. It’s tempting to buy whichever product has the most appealing scent, color, label, or simply the cutest packaging. But how do you really determine what’s behind that label? Let’s look at some of the high-level pros and cons of common hand soaps.

Foaming Hand Wash

I love the feeling of squeaky-clean victory achieved with a foaming hand wash. These foam hybrids of synthetic and natural ingredients can clean without entirely stripping your hands of moisture – but washers beware!

A few natural ingredients might provide some hydration while hand washing, but the synthetic ingredients will sneak up on you. The foaming action created by most hand wash foams is from sulfates. Sulfates can leave hands parched and prone to dry and cracks. Sulfates can also cause irritations like redness or itching and contact dermatitis.

Hand Sanitizer Gel

When you’re on the go, hand sanitizers are the best way to keep your hands germ-free. They're a great go-to in the absence of soap and water. Depending on the formula, emollients may help protect the skin from major drying effects.

But some of these concentrations can irritate the skin barrier, leading to the loss of its natural oils. Other times the skin might become dry and develop dermatitis, a skin inflammation that can appear as red, itchy, cracked, or sore skin. This could create an entry point for germs and infections.

What Hand Soap Ingredients Should You Avoid?

There is an increasing awareness that certain toxic ingredients have the capacity to sneak into your bloodstream with prolonged use. For health-conscious consumers, it is more important than ever to be aware of these hidden dangers.

Let’s explore the top offenders to fend off from our daily hand-washing routine:

  • Dyes

You may recognize these as a bunch of numbers and colors like Blue No. 1, Red No. 40, and Yellow No. 5. Soap companies use these color imposters or FD&C artificial dyes to give their products a bright, unnatural color. The dyes are derived from petroleum and might contain harmful contaminants such as heavy metals. Color me bad!

  • Sulfates

Get into ingredient detective mode and look for ingredients such as SLS or sodium lauryl sulfate. Though sulfates create that oh-la-lather we like, they can sap skin of its natural oils and disrupt barrier function. Beware of these sneaky, skin-stripping cleansing agents!

  • Perfumes

Most hand soaps contain fragrances (read: a mix of cosmetic ingredients in the formula not regulated by the FDA). The FDA even acknowledges that phthalates are commonly used in the fragrance industry. Who knows what other toxic ingredients could be lurking under the term “fragrance”?

  • Animal Fats

The sad truth is many animal byproducts from the meat industry are used in soap making. Rendered animal fats are essentially cooked-down parts of animals like cows and pigs. These fats are referred to as “tallow”, and are precisely the reason we don’t want to wash our hands with certain soaps.

What Non-Soap Ingredients Should You Look For?

All things considered, it’s important to note that hand soap seldom stays on our hands alone. We may be washing away impurities and germs, but soap residue remains. Toxic ingredients have the capability to not only enter the bloodstream but to be ineffective against fighting germs or illnesses.

Since we use our hands to do pretty much everything – from eating to holding our kids – it’s important to stick with washing our hands with nourishing, natural hand soap ingredients.

Glycerin

This intensely hydrating ingredient acts as a humectant, preserving and pulling essential moisture into the skin. Vegetable glycerin forms a moisture-locking barrier on the surface of the skin and is proven to leave skin feeling smooth and healthy.

Aloe

Aloe vera’s well-known soothing properties, antioxidant and mineral contents, and obvious hydration benefits make it a popular addition to natural hand soaps. Aloe’s healing effects have been recognized for thousands of years, making it perfect for all skin types – especially skin that tends to be on the drier end of the spectrum.
