Croda, and Purac to name two. What are you suggesting? I did a search of the Croda formulary. And you are right. Actually " Lactic Acid " appears in 5 different formulas and none of them are AHA products. For the record: ---- Clear Shampoo with ANCRINE SH-105 http://www.crodausa.com/formulations/Clear_Shampoo_with_ANCRINE___SH-105.pdf Here Lactic Acid is used to adjust the pH to 6.0 to 6.5 ---- Synthetic Liquid Soap BP-46 http://www.crodausa.com/formulations/Synthetic_Liquid_Soap_BP-46.pdf Here Lactic Acid is used to adjust the pH to 7 ---- Wrap Lotion HP-169 http://www.crodausa.com/formulations/Wrap_Lotion_HP-169.pdf Here Lactic Acid is used to adjust the pH to 4.3. This product is used after a relaxer treatment. ---- Ceramide A2 Shampoo SH-100 http://www.crodausa.com/formulations/Ceramide_A2_Shampoo_SH-100.pdf Here Lactic Acid is used to adjust the pH to 6.5 to 7 ---- Moisturizing Cream with CRODAROM HYGRODERM SC-289 http://www.crodausa.com/formulations/Moisturizing_Cream_with_Crodarom_Hygroderm_\ SC-289.pdf The only reason Lactic Acid appears in this formula is because it is a component in Crodarom Hygroderm (Cabbage Rose ( Centifolia) Extract (and) Sodium Lactate (and) Sorbitol (and) Glycerin (and) Lactic Acid (and) Serine (and) Urea (and) Glycine (and) Glucose (and) Allantoin) ---- Does it make any sense for inexperienced formulators to make and sell a potentially dangerous AHA cream or lotion without making any claims? I don't think so. Maurice -------------------------------------------------------- Maurice O.

Guest guest Posted July 8, 2004 Report Share Posted July 8, 2004 As for your question about inexperienced crafters making potentially dangerous products, what is your position on (said)using Sodium Hydroxide? ----- Sodium hydroxide is not sold as an anti-aging ingredient to be used in AHA products. It is not active in topical applications like the so-called AHA ingredients. In soap, once the oils are saponified, there is no radical lye waiting to sit on your face and eat it up. Unless you use a bar of that soap I made way back when we started, that could be a problem... Angie Quote Link to comment Share on other sites More sharing options...

I can't see inexperience formulators making hair relaxers using Sodium Hydroxide. Too dangerous. I've seen many people get hurt doing that. In the case of soap, the Sodium Hydroxide reacts with the fatty acids and the resulting product is not dangerous. Maurice -------------------------------------------------------- Maurice O.

Guest guest Posted July 8, 2004 Report Share Posted July 8, 2004 Just to add my two cents - I have been at this for under 5 years, which makes me a novice as far as I am concerned. While I am happy to see some of the more hard-to-find products becoming available to home-crafters, I believe it is up to us to really, really know what we have in our cabinets and are using (or selling). Personally, I wouldn't use Sodium Hydroxide or any of the AHAs to make hair relaxers, face peels, creams or whatever. Just the word ACID is enough to turn me off to it. Simple is best, IMO. The big manufacturers have labs and chemists at their disposal, I have my kitchen and Maurice ;-) haha... oh and Google... 8-) I'll leave it to the professionals. JMO!
