7 Most Common & Most Dangerous

Soap Ingredients

We always hear about cancer causing ingredients, or chemicals, but we usually seem to disregard them. At Bomb Body Shop, we do the research for you, and in this article you will learn about seven most-common dangerous soap ingredients to avoid.


Formaldehyde, and the are chemicals that release formaldehyde (e.g. diazolidinyl urea), are commonly found in soaps. Formaldehyde is known to weaken the immune system, leading to a reduced resistance to disease, and can also cause respiratory disorders, frequent headaches, chronic fatigue, and an irregular heartbeat.



Parabens (such as methylparaben and propylparaben) are preservatives that are a common ingredient in soap. However, scientific studies have repeatedly shown that being exposed to parabens boosts a woman’s risk of developing any form of breast cancer (because parabens mimic the action of the hormone estrogen). Further studies have demonstrated that parabens can also cause neurological problems by way of nervous system toxicity.



Triclosan is a pesticide with antibacterial properties. Often found in soaps because it helps to get rid of potentially dangerous bacteria that have built up on your skin during the day. This antibacterial action makes triclosan one of the worst contributors to the growing problem of antibiotic resistance (which encourages the evolution of resilient bacteria that are extremely difficult to kill). Another important reason to avoid the toxic soap ingredient triclosan is that it is what is called an endocrine disruptor.  Hormonal changes caused by triclosan can dramatically increase the likelihood of developing breast cancer.



Since dioxane is a synthetic derivative of coconut, some people mistakenly assume that it must be an innocuous ingredient in personal care products. However, it is actually a carcinogenic chemical that is also toxic to the brain, liver and kidneys. Like the other toxic soap ingredients in this list, dioxane should be avoided.


Sodium laurel sulfate (SLS)

Sodium lauryl sulfate (or SLS) is one of the most common toxic soap ingredients added to soaps and shower gels. One of the reasons SLS is so dangerous is that it permeates your skin very easily. Further, tests on animals show that SLS causes skin irritation, leads to organ toxicity, promotes hormonal disruptions and increases your susceptibility to mood disorders.


 Diethanolamine (or DEA)

Diethanolamine (or DEA) is also extremely easily absorbed through your skin, and it combines with the nitrate preservatives commonly added to soaps to create nitrosodiethanolamine (or NDEA). A wide range of studies have shown that NDEA is a potent carcinogenic, and it is most strongly linked to the development of kidney and liver cancers. 



PEG-6 is another one of these extremely common toxic soap ingredients. Studies show that exposure can cause a large increase in your likelihood of developing breast cancer.
