  • any reply will be greatly appriciated.
  • The best option is high molecular weight hyaluronic acid. It’s natural, acts like a humectant and performs well in presence of high concentration of active ingredients. Downside-price. If you don’t care about ‘natural’ label try seppuplus 400, great sensory, electrolite resistant. You won’t need more than 0.5% for a serum.
  • does hyaluronic acid be claimed as natural??

    Define "natural." (There is no legal definition in the US or EU).

    Using the term blithely as if it has objective meaning is an obstacle to the R&D process.

  • Disclaimer, when I said it's "natural" I was referring a common perception of the consumer, rather than any legal or scientific definition.HA is mainly produced via bacterial fermentation (or could be animal origin). It is occured in human bodies, and as such, often marketed as "natural" whatever meaning it has for the end user. Xantham gum and hyaluronic acid are made by bacteria, sepiplus 400 (which I absolutely love) is synthesised in the lab. That is why I said, "if you don't care about it being labeled as natural". You can claim hyaluronic is "natural", but I can't imagine there is a way to justify that label for a polymer like sepiplus 400. The main reason why I like HA in serums, is it's resistnace to a high concentration of active ingredients. It will gel anything at 0.3-0.5. 
  • By the way I noticed that The Ordinary recently replaced Sepimax Zen to Sodium Hyaluronate Crosspolymer in several formulations. One of examples is low pH 30% AHA peel. It is very diffucult to gel something with a low pH and so, they were using Sepimax Zen, which is rather sticky (and they were getting complaints). When I looked at their LOI last time, I noticed they replaced it to Sodium Hyaluronate Crosspolymer. I have not worked with this form of HA, but I believe that it must be acting as a gel maker, because they don't have any other ingredients that can form a gel in the formula. Which is bringing me back to the point that HA, is pretty nice gel maker.

    A couple of questions before I can answer.

    Why do you want to replace Carbomer?  Why not just add an additional ingredient to get whatever benefit you're looking to get?


  • @Perry want to replace carbomer because it gives bit sticky feeling. abd due to it when somebody with bit oily skin applies serum on face than due to stikyness of the product they get pimples on face. thats why want some ingredient which doesnot provide stickyness or provide least stickyness. 
  • If I could deduce what was in your formula I might be able to be more use.

    Carbomer isn’t sticky if you use the right amount Consider adding PEG-8 Dimethicone.  It will improve the sensory.
