That's a very valid point there.Thanks for pointing that out, Peri. Good point! Here's what I think:
It may be a trade-off situation, since the ascorbyl palmitate is only "slightly less potent" than L-ascorbic and is more stable. So, while we would use the less stable/more potent L-ascorbic in DIY formulas and just make a new batch every 2 weeks or so, in a ready-made serum the more stable/less potent ascorbyl palmitate might be better for use in a serum that sits on the shelf for 2 weeks before being shipped.
This is just my thinking on it....What do you think? I'm not trying to sell this stuff! LOL - Just trying to sort out what might be the better ready-made for ppl who are not interested in DIY.
Gymrat,And what is the deal with the Vit C serum. Someone on another forum said there is going to be some news coming out on it. What kind of news? Anyone know? It's all a bunch of BS and our faces are going to melt? Lol, let me know if you guys know.
Wow, I did not see that.Hi Peri
How did you get the Infopack to download? I'm still hassling around trying to provide them a website in order to be able to do it!!
I looked at that House of Deming website. Sure enough, their Cetic-16 C serum contains l-ascorbic acid, but look at what they have to say about it:
"Vitamin C (Ascorbyl Palmitate/Palmitic acid ester - Vitamin C) a natural antioxidant derived from Vitamin C and Palm oil. Most skin care products contain the most common form of Vitamin C, L-absorbed Acid, which is only water soluble (& not Fat soluble) meaning it will never penetrate into your skin, and thus it's ineffective. Only Vitamin C as Ascorbic Palmitate is both fat and water soluble, and able to be absorbed by the skin. All of PureDeming's products that include Vitamin C use only this form of Vitamin C. This form of Vitamin C is essential for the production of collagen and it also assists in healing inflammations and promoting the growth of collagen, which in turn, firms the skin. Additionally, it is essential in the prevention of collagen break down, resulting in combating the signs of aging. There is much confusing over which form of Vitamin C to choose: L-ascorbic acid or Ascorbyl Palmitate. L-ascorbic acid is sensitive to formulary concerns, including concentration as well as the pH level needed for it to remain stable, thus most topicals containing Vitamin C in this from are ineffective [they are not high unstable and inconsistent, thus you do not receive the benefits of topical Vitamin C. Though it is most often used as it is much more inexpensive then Ascorbyl Palmitate]. Ascorbyl palmitate, which is stable, has none of the product degradation concerns that L-ascorbic acid does, this is, also, why our products use this form of Vitamin C. Note: in our Cetic-16 we use pure Vitamin C, in the form of L-ascorbic acid. There are no stability problems given when the consumer gets the product, they add the Vitamin C powder to the premix base, thus ensuring its effectiveness."
What's up with that???
Yes, I'm hoping it will keep me warmer in the winter.Thanks Peri,
Is propylene glycol (anti-freeze) another example of an absorption agent? I'm pretty dumb about all these other chemicals....are they harmful?
