L (+)-Lactic Acid, 90%  USP
CAS: 50-21-5

New and Improved!  We're now offering Lactic Acid 90% -- made to Pharmaceutical Grade standards!  

L (+) Lactic Acid is the natural form of this ingredient often used as a milder alternative to glycolic acid in cosmetic formulations. Alpha hydroxy acids have been shown to promote smoother, younger looking skin by increasing the rate of cell renewal, improving skin texture and tone.

Lactic acid is often used as a natural pH adjuster in formulations.  Produced by the fermentation of carbohydrates, this product does not contain bovine, ovine, or caprine materials of any type.

Please note, we are not estheticians or doctors and we are unable to offer advice on formulating lactic acid peels or other information regarding its use as such.  Please consult a professional, as using lactic acid as a chemical peel or at an inappropriate strength can seriously burn your skin! 

Caution: Do not directly apply Lactic Acid 90% onto your skin. It is strongly acidic. This will BURN!  This product should be added to a formulation at the recommended usage rate.

CIR Review of Lactic Acid indicates it is approved for use at 10% or less, at a final formulation pH no less than 3.5, when formulated to avoid increasing sun sensitivity or when directions for use include the daily use of sun protection. Because products formulated with AHAs can increase sun sensitivity, the FDA requires specific labeling of products which contain AHAs and do not include sunscreens. This information and much more is contained in the FDA document USFDA on Labeling for Topically Applied Cosmetics Containing Alpha Hydroxy Acids as Ingredients. The link to this FDA document is also readily accessible in our Reference Room  (please consider it required reading).

Our Lactic Acid 90% is a USP (Pharmaceutical) Grade material, but it becomes Technical/Cosmetic Grade when we repackage it as we are not a pharmaceutical repackaging facility.

Our Customers Say...
The Shea Nilotica is awesome! Thanks for the sample... that sold me. You have been so helpful and I get so much great information from your site. Your formulary has prompted me to try a few new things. Love it! I'm a new customer but have already referred several people to you. Don't change a thing! I'm counting on you! lol
Karin Vinci, (Balance of Nature Bath & Body)

WOW. OUtstanding service.
this was my first order and i am amazed at how quick it went from ordering to processing to delivery to me.
My order was processed and shipped within just a few hours. I ordered early afternoon 12/16/2011 Friday and it was at my door before noon 12/19/2011 monday before noon. (i paid regular shipping) i have ordered my supplies from other companies and have not been so impressed. i will be ordering here from now on. thanks

A great experience. Prompt service, delivery in 2 days, box carefully packed with a thank you item, and when shipping costs turned out to be less than estimated, a partial refund. Email communication throughout the transaction really makes this company exceptional... Will definitely recommend to others. Thanks so much!

We had a small problem with our recent order and called customer support today. They apologized profusely for the issue and said they would call back with a resolution. They called back quickly with an excellent resolution. I absolutely couldn\'t be more happy with them. If they carry what I need I will NEVER buy it from anyone else. I am sold on LotionCrafter!
Vicky Anglin(

Wow, I can't say enough about my experiences with this company.
I have been happy with everything I've ordered and their pricing is very competitive but it is the customer service that sets Lotioncrafter apart from other companies.
Orders are processed and shipped quicker than any other company I've ordered from & each time I've received a refund for lower shipping costs before I even noticed!
Any questions I've had were answered right away & even received a phone call to explain things more personally.
Thank you so much for the great work!
