Sodium Lauryl Sulfate - Enemy or Victim?

All right kids, let’s start this debate.

Does it, or doesn’t it?

For those unfamiliar, Sodium Lauryl Sulfate (SLS) is a chemical

surfactant that is added to products such as toothpaste, shampoo, and

detergents to help it foam and lather.  It’s a salt compound (hence

the “sodium”) and is highly effective at removing oils and stains.

It’s also irritating to the skin if left on it for long periods of time.

So let’s see… in toothpaste… ground against teeth, gums, tongues, and

other mouth skin… highly irritating if left on skin… combined with

people whose mouths break out in open sores if they breathe in

wrong…

Yeah.  Not so good.

A study in 1996 was performed and states it like so:

The aim of the present clinical double-blind crossover study was

to investigate the effect of two different toothpaste detergents, sodium lauryl sulfate (SLS) and

cocoamidopropyl betaine (CAPB), as compared with a detergent-

free paste, on 30 

patients with frequent occurrences of recurrent aphthous ulcers. The study consisted of three 6-week

periods during which the patients brushed twice daily with the

different test toothpastes. The localization and number of new

ulcers were assessed. A significantly higher 

frequency of aphthous ulcers was demonstrated when the patients brushed with an SLS- than with a CAPB-containing or a detergent-free placebo paste. An SLS-free

toothpaste may thus be recommended for patients with

recurrent aphthous ulcers.

And luckily, sodium lauryl sulfate is in EVERYTHING!  It’s the high fructose corn syrup of the oral health care world.  They make

toothpicks out of the damn stuff.  The feeling of being totally

screwed.  I has it.

I certainly won’t argue with science.  However, I will say that

I tried an SLS-free toothpaste once and didn’t see any

difference at all.  I looked high and low for a toothpaste that

didn’t have

 it and at the time there wasn’t much to go by.  I wound up using a Tom’s natural toothpaste.  For me anyway,

the ulcers continued unabated.

But I’m trying it again.  On the advice of a reader, I’m giving Biotene a try. 

I’ve just started using it, and I have to say, I miss the foaming stuff. 

This just feels like I’m brushing my teeth with Play-Doh (and believe me,

I know what that’s like).  But I’m going to test this one more long-term

and see if it makes any kind of difference.
