Sodium Lauryl Sulfate Is a Safe Toothpaste Ingredient  -Roger Mason

Sodium Lauryl Sulfate, also known as SLS, is a natural foaming agent derived from the lauric acid in coconut oil. From coconuts. Because of its proven safety, good foaming action, and versatility, it is found in many different products such as shampoos, toothpastes, shaving cream, and lotions. SLS is used in nearly all toothpastes, because there is simply no good substitute for it. It is effective at a mere 1% concentration. Low foaming toothpastes using SLS substitutes have very limited popularity in the market place. People just don’t like them. SLS has been safely used by billions of people around the world for over six decades now. Over sixty years of worldwide proven safety.  There is no better proof of safety than this. It was approved by the FDA for human use sixty years ago. Sixty years of proven safety can’t be argued with. Criticism of SLS is simply scientifically unfounded.

There have been Internet scare stories circulated saying SLS is not safe nor natural. These are completely without merit, not factual, and totally ficticious. Please do not get your scientific information from these uncited and unscientific articles. Most all the natural toothpaste manufacturers, and all the major regular toothpaste manufacturers, have been using this with a complete record of safety since the 1950s.

Most companies believe this is the best choice for foaming action. Countless toothpastes  use SLS  such as Aquafresh, Nature’s Gate, Thursday Plantation, Arm & Hammer, Colgate, Crest, Gleem, Mentadent, Tom’s of Maine, Desert Essence, Vicco Ayurvedic, Sensodyne, Close Up, Pepsodent, Rembrandt, and Ultra Brite. Puritan’s Pride is the largest natural supplement company in the world, and uses SLS in their toothpaste line.  Kingfisher is the most popular natural toothpaste in Europe, and uses SLS. India has the most sophisticated and varied natural tooth-pastes on earth. Their Pearl-32 is the leading brand, and uses SLS with Ayurvedic herbs, especially neem (miswak). SLS is found in every type of toothpaste including regular toothpaste, toothpaste for sensitive teeth, all natural toothpaste, childrens toothpaste, and whitening tooth-paste.  It’s found in 99% of all the toothpaste on the market.

Young Again offered our very own all natural toothpaste until 2016. We discontinued them as the are expensive, hard to make, and didn't sell well. We offered 1% Beta Glucan, 0.5% CoQ10, Peppermint, and Tea Tree Oil.

The FDA has found SLS to be safe for toothpaste, shampoos, and various lotions and creams. Cosmetic Ingredient Review in Washington, DC has also certified it’s safety. A mere 1% concentration of SLS in toothpaste has been proven repeatedly worldwide to be safe and effective. Toothpaste was never meant to be swallowed or consumed like food. Toothpaste only comes in contact with the gums for seconds at a time, and then is quickly and completely  rinsed off. 

Some companies who sell SLS-free toothpaste have tried to claim that SLS is not safe. Yet, many of these same companies will put fluoride, saccharine, sucralose and other chemical abominations in their products. Some companies try to claim that people with recurrent aphthous ulcers (canker sores) should not use toothpaste with SLS, as they have chronic open sores in their mouths. In fact, such people should stop brushing their teeth completely with anything until they are cured. Mechanical brushing just irritates and opens these sores. They should rinse their mouths out with herbal mouthwash several times a day and brush their tongues to remove the deposits there until they are healed.  St Bartholomew’s Hospital in London (Oral Diseases v 5, 1999) did a double blind crossover study with 47 real people aged 10 to 62 with canker sores. They concluded, “None of the parameters measured was significantly affected by the use of the SLS-free dentifrice as compared with the SLS dentifrice.” The University of Oslo (European. J. Oral Science v 104, 1996) tried to claim canker sores had a slight relation to toothpaste with SLS. However, they clearly admitted, “The model used is not directly relevant to normal toothbrushing with toothpaste…” Unbelievable! This is science? What a disgrace!

You can get natural toothpastes online for about $6.00. It is worth the small price.
