    I bought from both places. I don’t think it’s anything special though.

    Hey Ngarayeva :) I didn’t know that you make a purchases from “Theformulary” I always thought that this site is a kinda fake. There are some interesting things there, and also the prices are reasonable.

    I use pure Inulin (Inutec) in my lotions at 2 - 3% and I’ve never noticed any traces of stickiness.

    Hi swaikstan, I live in Bulgaria and I understand the Russian language almost perfectly. I was visiting some russian and ukrainian forums for homemade cosmetic in the past, and I think the information there is quite misleading in general. If you want to gain your knowledge into the cosmetic formulations you’d better read the threads in this forum. Guys like Perry have a lot of experience in the proffesional industry, so their comments could be very useful. And ofcourse you should make some personal experiments to find out the answers of your questions.

    I’ve been using the Gosulin IL from the Gracefruit.co.uk, but honestly it is not my favourite emollient. I’ve found it a bit heavy and slow absorbing, also the skin tends to shines, especially on the face. The strange thing is that it contain about 95% Isoamyl Laurate, but i’ve been using pure Isoamyl Laurate (Esteroil from Alexmocosmetic) and it was quite different. The pure Isoamyl Laurate is light and actually a great emollient, but the Gosulin IL is not.

    In addition to the ngarayeva001‘s suggestions I would add Pentylene Glycol, Sucrose Stearate, Inulin. I am in love in the Inulin, ofcourse I can’t prove its efficacy, but the feeling when in the emulsion has the Inulin is fantastic!

    June 23, 2020 at 10:44 am in reply to: Homogenizer or Stirrer?

    @Graillotion And would $300 be affordable for a homogenizer?

    I would say that is very affordable. But unfortunately you’d still be stuck with the 300ml minimum volume you should use the homogeniser with. That’s the reason I didn’t go for the Dynamix + homogeniser attachment in the end. Otherwise it looked great.

    That’s not true at all! I’ve seen you already mentioned that in several places at the forum, but you can mislead the users which are interested in this device. Dynamix with the homogenizer attachment could cope with 100ml of lotion perfectly. I am doing a lot of experiment at my home and my base volumes are always 100ml. I’ve never had a problem with this volumes.

    I think 2-3% would be enough, but keep in mind that Cyclomethicone is volatile oil, so you have to add it to the cool down phase.

    June 17, 2020 at 12:07 pm in reply to: Sucrose Stearate Cold Process Emulsion

    There is a detailed explanation of how to use Olivem 1000 on the Hallstar website. There are two ways in general - to add it to the water or into the oil phase. If you add it to the water phase the soaping effect could be moderated very well. I have never had this effect yet, even if I use only vegetable oil and no any silicones. The important thing here is the viscosity of the emulsion, which is more liquid than these made with Olivem into the oil phase. However I find the Olivem 1000 quite stable emulsifier, with exceptional ellectrolyte tolerance.

    I know a lot of people which don’t like Olivem 1000, but I can’t imagine why? I like it a lot, and some of my best lotions are based on it. Olivem 1000 gives a deep moisturizing feel on the skin by itself, but I always combine it with other emulsifier. My best men’s moisturizer which has fantastic sensorials on the skin is based on Olivem+Emulprot.
    With Olivem 1000 is possible to make that so called “water gel” which is only Olivem + water. If you add a little Dimethicone you will get a great summer moisturizer, which is breathable, light with fantastic softening properties.

    June 16, 2020 at 7:55 pm in reply to: Sucrose Stearate Cold Process Emulsion

    I tried a few combinations : SS + GMS SE, SS + GMS Citrate, SS + Olivem 1000. I have used 2-3% SS + 2-3% from the others. From my point of view the most pleasant combination was SS+GMS SE, and the second best was SS+Olivem 1000 (both at the water phase). SS+GMS Citrate was a kind of heavy and draggy for me. Just to notice, that i’ve used SS not only as a coemulsifier, but as a moisturizing agent! I think you can’t use SS instead GMS Citrate because they are quite different by their nature. You can use both instead.

    I used to be use SS HLB 15 as a secondary emulsifier in the water phase, but to be honest I didn’t like its sticky feeling. About your formulation, I think the amount of SS is too small! Also as far as I know SS behaves better if it is pre-dissolved in water and left to rest for an hour or two before emulsification.I think, but maybe i’m wrong that at the second picture you have an emulsion fail. If you leave it for a couple of days it is possible to separate the water from oil.

    It’s a natural oil thickener, but also could be used as a substitute of the fatty alcohols.

    I think the Rotilabo homogenizer could be useful for for small volumes, under the 100ml for example. Dynamix should be used for volumes of 100ml and above. It’s head is too massive, and in a small beaker it will cause a “storm” then the half of the emulsion will go outside the beaker, and also it will put too much air in the emulsion. In my practice, when I test a new recipe I usually use my old Bosh CleverMixx with the baby attachment. With it i can mix properly small volumes under the 100ml.

    You are right, this lady has extremely unpleasant voice and pronunciation, but the English language isn’t her native language, so I think we should be more tolerant. My English is awful either, but I think you can understand me? Anyway, this video is very usefull espesially if someone is planning to buy this device. As you already noticed the information about this device is quite insufficient, and that’s very strange. I mean this device is quite expensive, and the lack of information is huge. At least this video can help the customers to figure out how this device work, and is it worths in general.
    By the way this device is very powerful, and after 5 minutes of work it getting very hot. I’ve been worried about that, and she helped me a lot. She told me that is completely normal and even the proffesional homogenizers can’t work very long. The same information i’ve got from the manufacturer. They told me that’s normal and the device will not broke if it’s getting hot.

    Yes….that is my plan B….
    Hehehe…..but I had in my mind….that I could find a reasonably priced unit….that did both steps…. Homogenize…and stir.

    I have a 6.5 Qt. Kitchenaide, and was just going to buy the paddle with the (bowl) scraper.

    Sounds like an opportunity for an enterprising individual! :):smiley: 

    If you take a look at the article you will understand that the paddle mixer and the homogenizer are different things. They are not equal, but as the author of the article said - the paddle stirrer is “must have devise” and more universal, and the homogenizer is a kind of lux.

    You can check this device https://www.carlroth.com/com/en/units/agitators-rotilabo-speed/p/n372.1 It’s much cheaper than Dynamix.
    You can see the comparison between Kai Blendia and Dynamix by the same author.

    Like this?

    Yes that’s my device! By the way the homogenizing unit is made by high quality metal and it’s very easy to be cleaned. You don’t even need of dishwashing gel, the metal surface doesn’t hold anything so you can clean it with just a water.
    Well i don’t know what’s the problem with the link, but however you can paste the title of the article in Google.

    Take a look at this article. It seems that the homogenizers for home use like Blendia, but the Dynamix is quite similar, so they can’t achieve a stable and finer emulsions compared to the professional devices.

    My “stirrer” is actually a plain kitchen mixer by Bosch. Since I am cosmetic formulation hobbyist I can’t afford for myself a professional propeller mixer. The idea is that after the homogenization, the emulsion is getting thick, so the homogenizer can’t work properly. I’ve bought my Dynamix at Ebay uk in an auction. It happened quite accidentally. By the way I can’t tell the real difference between my Dynamix and my Bosh immersion blender which I have used before. The Dynamix works by completely different way, and it does the job faster. I mean if I need to emulsify the emulsion for a 5 minutes with my Bosch blender, the Dynamix takes only 2 minutes. Also the emulsions made by Dynamix have a bit lower viscosity.

    I think you are in a big mistake! You can use Dynamix homogenizer only at the first 2-4 minutes of emulsification, then you should switch to propeller type of mixer, because the emulsion need of different type of mixing. Also the Dynamix does not have 0 rpm-s, so at the lower level the rotor stator head is moving but slower.

    May 27, 2020 at 10:48 am in reply to: Stickblender makes hair product too foamy! Help!

    The trick is to keep the blending/emulsifying head beneath the emulsion.If there is a contact with the air, it will bring it into the emulsion. I have the DYNAMIX DMX 160 homogenizer which I bought from Ebay, and I am very happy with it, but if I am not carefull it can put an air into the emulsion. However you can remove the air during the cool down mixing. You cannot use the homogenizer for more than 3-4 minutes, because it’s getting hot. You have to switch to propeller mixer after the homogenization, and then it can remove the air.

    May 13, 2020 at 5:50 pm in reply to: Soaping and dimethicone….. 6 or 350 CST.

    I have two types of Dimethicone at home - 50cs and 1000cs. The last one I’ve bought it from Gracefruit.uk. The difference between both is huge. The 50cs is liquid like water and could be substitute of the lightest oils. However, it is suitable for male cosmetics and oily prone skin. I’ve tested it for a couple of women, and they said that the product is too light and their skin “needs more”. That’s dependant not only of the Dimethicone of course! On the other side the 1000cs is more viscous and gives a kind of consistency of the product. I guess the 350cs stays somewhere between.

    May 6, 2020 at 9:40 am in reply to: Is there a go to emulsifier for premium lotions?

    Don’t waste your time and money with the Montanov 202. I have been used it in the past, and have to say that it is a bit tricky emulsifier with unpredictable stability.

    May 5, 2020 at 7:55 pm in reply to: Creams breaking/curdling in the cooling phase

    Well, that’s a question of personal taste. Me personally prefer to make a lotion like emulsions, because I am concerned about the safety of the products. Basically I use airless dispensers, so me and my clients are not able to touch the whole emulsion with the fingers. I noticed that the GMS SE is able to thicken the emulsion too much, so I carefully dose it’s amount. I don’t know, but I think that too much consistency modificators could make the emulsions hard to absorb. I guess it’s a question of tryouts to get the proper proportion.

    I use GMS SE in my lotions and have to say that it’s fantastic coemulsifier. It’s anionic by nature, so it benefits the main emulsifier and makes the emulsion more thick and stable. I have a recipe that is combination between Olivem 1000 and GMS SE and would say that is one of my favourite formulas. I always put Olivem at the hot water phase, and GMS SE at the fat phase. 8% of Olivem is way too high. Also the amount of the butter is too high for me. In most cases the amount of Olivem which I use in general is not more than 3%, and the amount of the GMS SE is not more than 2%. Just keep in mind that the GMS SE is an emulsion thickener, so you need to reduse the amount of butters at all. Also I process my emulsions with Dynamix homogenizer which is high speed shear process, but my emulsions are stable even after an year.
