MemberNovember 24, 2020 at 2:39 am in reply to: What preservatives do you use most often?Formaldehide.
We have no restrictions, so, in our country drinking water also contains formaldehide.
Less than 1$/kg, and works like a charm.

@Pharma thanks you very much for your input, do you know any supplier that sells diluted gluthatione?, i mean i put on the web “glutarhione supplier” and i cant find anything in usa, but Just pilla and oral suplements. Btw there are a lot of supliers in Alibaba and india, but i need in usa.

Im making a Dean-stark alike aparatus for a 100l reactor to make some esters, my problem right now is that i cant buy Sulhpuric Acid, i Will try with phosphoric an see. I Will try Benzyl and n-propyl acetate .
Im pretty sure that you cant Achive a Esterificacion in normal conditions. You Will need to Heat and mix the product, the pressure Will rise a little although you need to use a reflux condenser and a wáter trap
You also need a catalyst as h2s04 to beging the reaction

@belassi hello my friend, the past week i make my first destilliation of some esencials oils. Im waiting some Sulhpuric Acid to start the estereificarion of some fragances , i Will coment the results

@Pharma thanks you very much for your input, all your informatión gives me a start, i can buy any of all the products i listed. I just cant afford yo buy all of them. So listening to tour recomendation i Will try:
Methyl,ethyl and isopropil Benzoate
Methyl,ethyl and isopropil PropionateI have a Dean-stark alike aparatus to remover excess wáter, buying Sulhpuric Acid and/or chlorhidric was a pain, and It has so Many regulations on my country because they are used un the production of cocaine, is a good news to know that i can use phosphoric

I mean i just want a tip ti beging sterification. I mean i cant afford buying all those rawmaterials Just to try all the mixes, for example there are a lot of esters that smell like Banana for example, nobody wanta banana smell on the floor. On the other Hand according to a little of research on internet It seams that there are a lot of esters that smell like cherry, well if someone can help me to select an Acid and alcohol ti beging i Will vevery grareful.
I was aiming to make Benzyl acetate, It seams to have a pleasant jazmín odor.

@Belassi hello how are you?, Well, im not trying to compete with giuvadan, im only aiming to make some esters for simple products like floor desifentants, im not aiming to sell they, Just to use use for my own products, in your country is easy and maybe cheap to buy fragances, but in my country there almost no way to buy fragances locally, and the shipment are very expensive, we are blocked from Usa and their allies.
I have made esters in lab, and i have the equiment yo make 150kg batch, a small stainless steel 200l reactor with, mixing reflux, condenser and heating capabilities. Im ussing it right now to destil Orange and lemon oil.

MemberJune 24, 2020 at 2:06 am in reply to: Dishwashing Liquid Clouding and Precipitates AppearHello, as @Chirag sugested, you need to measure the ph, over neutralized or an acid liquid soap could be cloudy, your formulation is very much the stardar for a cheap liquidsoap

Cafe33 said:What do you mean H2SO4 is illegal in your country? There is no way you can outlaw such an important industrial chemical. Buy it with the proper paper work. You won’t need much for fischer esterfication considering it is a catalyst.
Yes h2s04 needs a very very special paper work, because its used un the cocaine manufacture. You can find small dilutions for LAB propourses but they arent cheap.

@Pharma Hf is legal in My country, can’t Buy fresh battery acid, sulphuric acid is very ilegal arround here, i Will try phosphoric
-
Thanks You @Gunther for your answer, it is about 30% more expensive buying 28% sles, it takes 2.5 more volumen to tove shipped My country, i can’t afford that.
There must be a suitable pump, i’m buying sles from LG household and they are selling a Lot 70% drums, so i’m wonfering what kind of pump are ussing the industries, worm, gear, pistón pumps.

Im ussing 3% ctac and 3% cetyl/stearyl alcohol n 50:50 and works fine in a standard condiciones, i ussed pq7 and 1000cps dimethicone but i didnt notice any difference
-
@Pharma thanks you for allí the input, sulphuric Acid os forbbiden un my country, It is ussed for making cocaine so is banned, what about ussing hidroflourhydric Acid?, Is strongest and more reactive than phosphoric.
-
Belassi said:I’ve done that reaction but only with sulphuric acid, you will have to try it for yourself.
HI belassi, como estas?. Thanks you very much
-
Pharma said:It is possible but you have one main problem, water! Esterification only works in anhydrous systems and HCl comes at <35% aqueous solutions. Trying to remove said water by evaporation will evaporate HCl first whilst chemical or adsorption strategies (such as anhydrous Epsom salt or molsieve) will turn HCl into a gas and then you’ve got to run. You may want to try phosphoric acid or acetic anhydride
. In the latter case, you have to gently neutralise the excess acetic acid before solvent extraction or distillation.
Im thinking in use an aparatus like dean-stark water separator, but it would be awesome that i could use phosphoric acid, have you made an experimento ussing phosphoric?

talking about powder detergent, im ussing:
20% Methyl ether sulphonate
40% pulverized SOAP
20% Sttp
10% sodium sulphate
0.5% CMC
Rest aditives, fragance, colorants, others.The foam is very good, but soap tents to make scum and some times MES and SOAP are hard to dissolve, does the Sodium sulphate in your formula its cappable to abdsorb your liquid labsa-sles-betaine with out making a cake ?

Hey @Gunther i have Made a 18% Labsa dishwash as sole surfactantes And i havent cloudiness issues, i’m fact above 16% the viscosity is very good, check And control the rise of temperature, And try without other Labsa suppliers
The experiment where Made when There our supplier runout of sles.

MemberDecember 25, 2018 at 10:11 pm in reply to: Should I dilute sulfonic acid before neutralizing it with Sodium hydroxide ?Gunther said:I wonder if 15% LABSA is too much15% isnt too much, i have used 18% labsa with naoh alone to get a viscosity similar to a famous brand in my country, and worked exccelent, it was clear and light yellow.
Today im ussing arround 8%, ussing sles / betaine to build viscosity.
I have found that mixing and avoiding the mixture to heat helps to get a lighter color and clearness

Indeed 99% of my little knowlwdge was adquired making trial and error, i have a degree in “oil-chemical proccess”, in fact in my country cosmetic-chemist degree doesnt exist and bassically there arenot cosmetic manufacturers, alll the products that are used here are imported, its a pain to find someone that barely understand cosmetic chemistry, our country its mainly oil/gas exporter, despite that i strongly belive that a chemestry background its a must.
The same way a doctor can say thar all hes knowledge was adquiered over the years, i will no feel confidence if a lawyer is going to make a surgery althought he claims that he has done it for 10 years or so.
