I've been using Olay daily facials clarity toner for awhile and am really happy with it. On the bottle it says it has a "dual hydroxy complex". It has salicylic acid for sure, and I was hoping the other was glycolic acid (even though it wasn't on the label, I thought it might have some wierd chemical name I didn't recognize).
So I emailed the company to ask. First they said they needed the full name of the product (which I had already put in the subject line-duh) Then they just emailed me a list of the ingredients and said "see, idiot, glycolic acid is not on the label" and ignored the question about the "dual hydroxy complex". So I wrote back AGAIN and finally got this reply:
I've checked into this further, and the Dual Hydroxy Complex in our
Olay Daily Facials Clarity Purifying Toner is made up of Salicylic Acid
and Sodium Dehydroacetate. Together, these ingredients provide acne
treatment, skin exfoliation, and unclog your pores.
Was that so hard?  So, thanks for letting me vent, and my actual question is what the heck is this stuff (Sodium Dehydroacetate). Does it have another name I might recognize? I've googled it, and it seems to be some sort of antioxidant? Most of the sites were selling chemicals, so they weren't very helpful. Anyone? Thanks! |

From the book Skin Care & Cosmetic Ingredients Dictionary written by Natalia Michalun
Sodium Dehyroacetate
A preservative against bacteria and fungi that is used in concentrations levels of 1.0 percent or less. It is useful in combination with parabens. May cause skin irritation.

The stupid lady said it was part of the "dual hydroxy complex"! That doesn't sound like a hydroxy acid to me! I wonder how a preservative is helpful to "provide acne treatment, skin exfoliation, and unclog your pores"? Either it's false advertising or she doesn't know what she's talking about.
Thank you for the information, it does help.  |

| You're welcome! It's her ineptness that caused her to give you and many others the "supposed definition". I highly recommend the aforementioned book for anyone who is interested in skincare. Try ebay and amazon.com for used copies. |

| Can you list the eintire ingredient list? I'd be interested to see what type of acid the other AHA is also! Lifeplyr01 is correct, sodium dehydroacetate is a preservative. |

Here's the ingredient list:
Water, SD alcohol 40-B, sodium dehydroacetate, aloe barbadensis leaf juice, salvia officinalis (sage) leaf extract, camellia sinensis leaf (green tea) extract, panthenol (pro-vitamin b5), fragrance, isoceteth-20, disodium EDTA, green 5, red 33
Also, the 'active ingredient' is listed as Salicylic Acid 2%.
At least it seems like it's mostly natural stuff (besides alcohol as the 2nd ingredient ) I know it's bad, but I like the tingly, anti-oily effect of alcohol in a toner.
Maybe someone can spot the other 'hydroxy'
Thanks for all your help, guys! |

Well, alcohol is a must in a salicylic product, unles it is an emulsion, where it can be dissolved in the oil phase. I have to say, I am stumped. I see no other hydroxy acid in this. And I am surprised that the sodium dehydroacetate is the 3rd ingredient. Maybe it has an exfoliating effect at high concentrations? But it still is not an AHA. Very odd!  |

| Why is alcohol a must in salicylic products? |

I believe it is necessary to help aid in the penetration or delivery of the SA. Not sure on this though.
I'm stumped as well on the "other hydroxy" in the cleanser..I just don't see anything in the ingredient list. Maybe it's just false advertising. |

Salicylic acid is soluable only in alcohol or oil.
SA is also more effective dissolved in alcohol. If you have a 10% solution in alcohol and a 10% solution in oil ... the 10% solution in the alcohol is going to be stronger than the one in the oil as the oil also acts as a buffer.

| I believe Sodium Dehydroacetate is a skin active but also has a dual property as a preservative due to its anti-bacterial properties. |
