    There are two sellers of SCI on eBay as well. I use eBay UK but these suppliers are in the USA and will export.

    I think SCI is the nearest you will find available in small quantities.

    Completely agree with Bill.

    Regarding the grade of Carbopol, 940 is specifically designed to give very transparent gels and to do this it sacrifices some other properties -like tolerance to electrolytes. If you want to continue to use the original Carbopol types, 934 is the one to use in emulsions although I should point you in the direction of the more modern versions which are much more versatile.

    Not a direct answer to your problem, merely an observation, but I would never use Carbopol in a formulation like that - especially Carbopol 940 which is designed for “sparkling clear” gels.

    Because of the legislative restrictions on these products it is a very small market. It worth anyone’s time and effort to formulate anything new and for any marketer to sell them?

    The two Allured magazines Perfumer & Flavorist and Cosmetics & Toiletries are livelier now than they ever were and everyone who qualities to have them should do so.

    It isn’t necessary to completely neutralise all of the fatty acids present in beeswax to form an emulsion - it’s probably best not to do so.

    The degree of neutralisation will, in most cases, depend on the formulation itself and the effects you want to achieve.

    There are lots of companies which repack ingredients into small amounts for the small/home user.

    All you need to do is seek these out via Google (or other search engine).

    This is far too wide ranging for anyone to be able to give a meaningful answer.

    There are thousands of potential ingredients for cosmetics and perfume.

    This is a very old thread which was brought to the fore by a troll advertising anti-cancer something or other and which I complained about. The post from markfuller must have been made just before the troll post was deleted.

    What is this obsession with borate compounds?

    As I remarked above, there is nothing magic about using borates as emulsifiers.

    There are plenty of other, better, materials that can be used as emulsifiers and sodium hydroxide in a suitable aliquot, can directly replace borax quite successfully in almost all instances.

    March 7, 2017 at 8:15 am in reply to: The first formula I ever made was………

    The first thing I made was a supposed knock off of Brylcreem from a formulation I found in a boys book of practical chemistry. I was about age 14 and was lucky enough to have a local pharmacy (they were called chemists shops at the time) with a helpful pharmacist who obtained the ingredients for me.

    The resultant emulsion was quite successful but the resemblance to Brylcreem was minimal.

    Later, as a college student, I obtained a part-time job at the pharmacy where I learned a huge amount about formulation. In those days it wasn’t a case of the pharmacist doling out preformulated, prepacked items from a shelf, lots of medicines were actually made from scratch. It was also the days when prescriptions were handwritten in dog-latin in ounce (and fractions thereof) measurements - grains, mimims, scruples, drachms, ounces, pints etc. with all their associated strange symbols derived from alchemy and all designed to disguise from the patient what medication they were actually receiving.

    I doubt there are any aqueous systems that will dissolve zinc ricinoleate that don’t result in its total decomposition. If there were, I’m sure it would have been done by now.

    Zinc ricinoleate will dissolve in NaOH solution but it is completely decomposed into sodium zincate and sodium ricinoleate.

    As you are a beginner, I don’t think you should be venturing into more than one project at a time (noted and responded to your perfume post).

    A lot of members here are in this business as their main employment and require to make a living. It is, I feel, unfair of you to request formula information without giving any input yourself.

    There is a lot of manufacturers and suppliers literature online which will give at least some information to start you on your quest.

    There is a huge amount more in the creation of perfumes than mixing essential oils together.

    Perfumers train for many years before they are able to create an item that can be described as a perfume (and not a random mixture of essentail oils and odorous chemicals).

    Bearing that in mind, it is not possible to state which fixative you should use.

    4-10 hours, I would think, is long enough for a perfume to last on the skin.

    with regards to worldwide restrictions on borax do you have any brief
    info on this? i know there are restrictions in place under the EU here,
    but only on the sale of it, not the use of it in products (there may be a
    limit to % allowed in a product, but i am only using it at <1%)

    The amount of information available on this subject is too large for me to give a reasonable précis. Remember that Google is your friend and your access to it is the same as mine.

    Please note also my earlier reply:

    the large maufacturers of beeswax/borax products have been busy
    reformulating to remove borax e.g Unilever have reformulated Pond’s Cold
    Cream and replaced borax with sodium hydroxide.

    gregwhite There are some occasions when the questions posed in enquiries are new and for whatever reason there is currrently no answer.

    It is apparent to me that what you are are asking is one of those questions and nobody that has read this thread has tried to carry out the procedure you want to know about - hence the reply from Belassi

    It will help fill the pool of world knowledge if you do try it yourself and report your findings on this forum.

    Whatever you think about the properties of borax, there are worldwide restrictions on its use. Those of us with commercial interests must heed this, no matter what their personal view - hence my own comments.

    March 4, 2017 at 7:30 am in reply to: Rosacea actives

    I can assure you the xylometazoline and every other drug with vasoconstrictive properties has been tried for this end use!

    I think this query should be directed to the rosacea forum (link as above) where there are a number of experts (and sufferers) who will be able to give meaningful responses.

    Rosacea and its associated conditions make up one of the areas of my R&D work. Thus I am unable to offer any practical help.

    Was the coffee prepared in the same manner each time? If you made the coffee in bulk and saved for different batches, was it adequately protected from microbial attack/other decomposition (hydrolysis of one or other component)?
