    With no information as to the constitution of these products it is not possible to give any meaningful response.

    The Amazon link you gave does not reveal the LOI. From where did you obtain this?

    As it is a Bulgarian product, it is possible that some pertinent information had been lost in translation e.g a strong oxidising agent like peractic acid seems a strange ingredient to have in the presence of panthenol (which is sensitive to oxidising agents).

    Ah! I see. As it is a new material with little information available. again the answer would best be given by Showa-Denko.

    I would be inclined not to experiment too much with different mixtures at this stage until you have a “feel” for the material.

    I always see a cost problem with using sclerotium gum in a product like this but they are synergistic so it could be worth investigating.

    Xanthan gum is stable in alkaline systems.

    Also most clay thickeners such as Laponite, Veegum and hectorite/bentonite.

    You are requesting development work for a new product. This normally demands a fee.

    This thread is becoming very confused with several distinctly different questions being posed.

    May I suggest that each party asking advice start a new thread.

    The declared LOI is: Water, Sodium Trideceth Sulfate, Sodium Lauroamphoacetate, Cocamide MEA

    Knowing that, there is no need to pay their high prices for a mixture of common surfactants

    I’ve just followed my own advice and Googled Majestic Pure and found that they are not, as you intimate, major suppliers af anything at all but are, in fact, small time oil and aromatherapy materials suppliers to the domestic market.

    So, what I consider “bulk” or “large” would be something of a misnomer to you.
    My understanding of bulk quantities are amounts in excess of 200kg -and I’m now certain that your requirements are nowhere near that.

    In regard to Majestic Pure, I note that they have some very bad press being accused of selling fake materials - perhaps that is where your grassiness-free peppermint oil originates.

    What is your definition of “bulk”?

    The problem you will find in trying to source large quantities of peppermint oil is that most of the world’s supply for many years ahead is already bought and (perhaps even) paid for by the large users - for use in flavouring dental products (toothpaste etc.) and a smaller amount in foods.

    Anyway, that aside, but again depending on your meaning of “bulk” your best approach would be to contact the agencies in the countries where you think the best product comes from. Trade magazines and our friend Google can help enormously here.

    I am surprised that your current supplier is unwilling to help you. Even if they are unable to supply themselves they ought to be able to buy material in or put you in touch with another supplier.

    Does anyone know the price? Hopefully it’s compatible with glyoxilic acid.

    The way to find out the price is to ask the manufacturer/marketer. In most countries it is being marketed by Azelis.

    In regard to compatibility with glyoxilic (sic) acid, do you mean pricewise or chemically/physically? In the first case I doubt it, in the second case I have no idea but, I don’t see the relevance of that query.

    A bit of advice.

    Remember that sterility is lot almost as soon as you open the container. If you are not using the whole of the contents in one go I suggest that you add whole whole quantity of the preservative you will be using in your product to the water.

    If you are making different products with different preservatives, do the same with each bottle you open and mark them carefully.

    Natrosol may be cheap but you should also factor in the added production costs (particularly time) involved in dispersing/dissolving the material.

    April 22, 2017 at 6:40 am in reply to: Concentration of Emulsifier?

    Very rare is the cosmetic emulsion that comprises only three ingredients (oil, water and emulsifier). Additions such as solvents, emollients, electrolytes, different types of oily material and many others will profoundly influence the formation and stability of an emulsion product. This is where the knowledge and experience of a cosmetic chemist or formulator is invaluable. If cosmetic formulation were as simplistic as you seem to want or expect, most members here and lots of others would be unemployed.

    The singular example you gave:

    I only found one laboratory/manufacture of cosmetic supply ingredients
    that mentioned an “optimal” amount would be 10 percent matching the
    Lipids phase - for example if you have 30% lipid phase, then they
    recommend using 3% emulsifier(s), which should be a blend of high-HLB
    and low-HLB emulsifiers.

    shows little knowledge of the real world and I suggest it should be ignored - similarly with the next sentence in your post.

    The product itself may be OK but the problem with most, if not all, eBay sales is that they are here today, gone tomorrow. If you want continuity of supply you would  be better looking elsewhere. The same product is available from several sources - with probably a more consistent supply chain.

    A few % of ethanol may help with the soaping - and give a slightly faster drying product.

    I have seen the outline of the ingredients of the Seppic idea and I can say that the whole purpose of providing that information, Seppic are promoting the sale and use of their own raw materials. Practicability, performance and, very importantly, cost are way down their list of requirements.

    With all due respect, you are not in the market to promote innovative products like that and to even think about selling something so different without a huge marketing backup is doomed.

    nabil, have you noted the date of this thread?

    If you are just querying the feasibility of adding Natrosol to the formula, I recommend that you do not do this but adjust the viscosity by some other means such as salt.

    There is a new product recently introduced by Showa-Denko called Spiera.

    It is intended as a gentle permanent wave active. Please don’t reject it as an associate did recently because it is for permanent waving as, by the same process, permanent straightening can be achieved just as easily.

    The cost of the solubilisers suggested is tiny compared with the cost of a fragrance compound.

    Bonnerja, you ought to start a new thread - it will give you a better response.

    When you do that, send more details of your formulation as the information you have given is incomplete and it is difficult to determine exactly what you are doing.

    I am also curious about soap free shaving creams. Can you name some, please?

    As people seem to think I am writing rubbish here, I have also found this:

    DRBOB, I agree with your observation but isn’t it better to avoid any humiliation by having a product that is effective before it reaches the marketplace

    The ultimate arbiter in marketing any product is the buyer and repeat sales.

    If a product doesn’t work there won’t be many more sold after the initial purchase and you may even get complaints - with a diminution of reputation.
