The common names of them are crioprotectors or anti-freezers…Or do you need exact examples of them?

Yes, it would work alone.

Possibly DMDM Hydantoin…

I guess the TS means the sculpting gels for fingernails based on acrylic oligomers and UV polymerization.

Interesting discussion! From the scientific or clinical/dermatological point of view my answer for the primary question is “waste money and resources” unless a customer(marketing or salesmen) wants to get a fancy (“natural”) formulation or merely get up the price for the final product.
I’ve been working a lot with HA and FA and I can’t tell they really work as they are advertised if we compare to other trivial ingredients.. There are plenty approaches to formulate a really working product without spending such big money and using the above mentioned petrolatum is just an example. Just try to combine it with glycols, urea, some salts and gelling agent and you get really nice product.I still don’t see any convincing data or evidence of advantages of the topical use of HA or FA. -
What do you mean exactly?

I doubt amino acids are able to penetrate the skin barrier and even it may be possible - what are they supposed to do in the skin layers? However, I have got an experience of working with them in some formulations using their properties. For instance, L-Arginine appears to be a nice neutralizer for Carbopols giving the final products very pleasant sensorial feeling and additional conditioning effect especially in nail and hair formulations. It’s also widely known as a functional ingredient in acid based peels for the professional cosmetic practice. Glycine is able to improve the quality and some properties in hand made soaps.

Again, thank you Bill_Toge for the advise. I have tried lavender EO and it’s work great. However, I have tried EOs of Litsea Cubeba and Black pepper. I have to admit, the mix of Black Pepper EO ( From India) and DMAE salts works the best way masking the smell. Mix of those two odors yields the absolutely beautiful smell of cedar wood. Excellent! It’s interesting that Black pepper EO from Brazil doesn’t work the same way at all. I also have to note, that any synthetic mixtures don’t work…

@Bill_Toge Thanks a lot for your advise. I’m going to try it and come back to share what I get. I like all your comments here - they always “work”

Simple and very true article

I guess, apparently it is Salycilic Acid a culprit. 1% would be too high for mask form. Try to cut the % to 0,3 -0,5% I believe it helps.
-
I guess, big guys have begun to show there is no fear in using PEGs
That’s really looks like a trend against all those fear mongering -
I’m sorry - there is no glycerin formation in this reaction: KOH + myristic and stearic acids.

@EyeLovedMakeUp, hello! Have you tried Dermablend? It seems they have got everything that match to every possible skin tone? I admit it would be interesting idea

Eurovetrocap offers the packaging for mascara, etc Probably they don’t put everything at their website. We have ordered their catalog.

hello! here are all FDA permitted colors and color additives

@The_Microbiologist, Thank you so much for interesting and important information!
@Bobzchemist , Well if you develop medical/hospital grade product, you may try the following options:
- Phenoxyethanol
- Sorbic acid
- Citral, which bring additionally the pleasant citrus smellAll of them are highly compatible with surfactants in liquid soaps.
-
@cossci21, You may want to try L-Arginine for this purpose.

I’m really not sure about FDA requirements for the antiseptics. I’d like just to mention that in almost all American nail products manufacturers use “Sanitizer” instead of the term “Antiseptic” both in sprays and the soaps (liquid or regular).
As alternatives to Triclosan I have successfully used Thymol. It works great as an antiseptic in a wide range of products I have created. Consumers like it also, since it has a “green” background and considered to be “natural” which is relevant nowadays.
Another option would be Hexamethylenetetramine, but it’s Formaldehyde releasing stuff.
And finally you may try quite original twist in such products with regular mixture of preservatives used in higher %%% in purpose to give antiseptic effect. (I have used Phenochem by Sharon Lab.)
What else - guess the regular KOH or NAOH (depends on the soap formulation) at up to 3,0%. It yields some skin drying effect which could be conquered by additional glycols or other possible moisturizers in your formulation -
Bobzchemist, David, that’s some kind of insights and many things has become absolutely clear for me - those details are so important to know. Thank you for your help!
David I do appreciate your help with share the information you’ve got - I will e-mail you shortly. Again, thank you
Cheers
-
David, that’s interesting experience, thank you!
Bobzchemist, It was nice purple prose
-idiomatic and simple explanation -
I have noticed many times that adding PEGs or even Alkyl PEG Ethers help to solve the problem in some formulations.
-
David, Bobzchemist, Thank you for your thoughts. Indeed, it looks like we have to ask for help with some consultant to register. Despite of tons of information at FDA website, all the data is too ambiguous and really confusing. Though I couldn’t find any pricing for their services at all and I guess it’s enormously high.
It’s still unclear - should I register as a manufacturer in a case when I order the product at some contract manufacturer.
