Professional Chemist / FormulatorFebruary 8, 2019 at 7:35 am in reply to: Machinery for a start upI use a custom made filling machine made by Universal Filling Machine Company in the UK. It is very well engineered, precise, and hand operated. http://www.universalfilling.comPart of the process was that I sent samples of our liquids to them for testing before they released the machine. To-date, after four years of solid use, the results have been excellent. It covers bottle sizes 30 mL to 250 mL +Price ex-works in 2004 was £3,450.00. I’m very happy with this machine. -

And if you’re a new brand one of these guys might buy you up if you get big enough.Yes, indeed. This happened to Le Labo, founded in 2006 by a couple of French guy who initially had trouble attracting investors who just couldn’t get fired up with the business plan. So they went ahead on their own.In 2014 they were purchased by Estée Lauder. Worry now is with this corporate backing, Le Labo will lose its indie appeal and all the exclusive qualities that made it. I guess time will tell.We have had approaches, but I’m simply not interested. Love making things and not having others telling me what to do.

Professional Chemist / FormulatorDecember 28, 2018 at 10:56 pm in reply to: Question about starting a cosmetic linedeannaji said:Hi everyone,I have a question about starting a new cosmetic production line (from home, for starter). Do I need to be cleared by HDA, FDA or any other organizations if Iam planning to sell online. I do line in CA, US.Cheers!It can be done, but you need to be realistic and have a plan. I started out working on a few recipes using a corner in the premises of another business. When things started to look promising I took over the premises, hired staff, and then worked on the GMP, and product registration with the cosmetics authorities, etc etc.As things progressed, we then moved country where we had better international air and sea shipping facilities. And again built a premises that is GMP and Halal Certified.In my experience, starting at home is a good starting place. If you see potential, then you MUST be prepared to invest in proper GMP facilities and the required staff. Yes, GMP id expensive, and you need the staff. NEVER expand too much without the GMP facilities. If you do, it can turn into a disaster if you are caught.Follow your dreams. I did, and you can read about it here: https://indochinenatural.com/the-indochine-natural-brand-story/ -

Professional Chemist / FormulatorDecember 3, 2018 at 1:51 pm in reply to: Question about starting a cosmetic lineMicroformulation said:Honestly, under cGMP standards you should have a separate space for Cosmetic manufacturing, to start. I would recommend using a manufacturer and dedicating my time to brand management. A Cosmetic Manufacturing Facility and a Cosmetic Line are very different Business models and it is not sustainable to do both over time.Agree 100%. We started as a brand manufacturing our own products, and within a short time we were doing 80-90% OEM/Private Label. Our own brand suffered as a result.If we were to do it again, a clear decision would be made. Do we want a production facility, or our own brand? Make the decision. Then stick to it. -

ThanksHave looked at this article. In my opinion ‘Dermatology Times’ does not appear to be a legitimate scientific journal. After 40 years as a scientist, I have a fair idea of what a scientific paper looks like.Have I missed anything? It’s always possible. -

I think it is an outdated technology though.We make and sell a lot of traditional cold-process soap. Outdated maybe, but it sells. Is there any other reason to make new or old technology soap?Agreed, its a niche market.Effects of long term use? For me 30+ years. Plus thousands of customers. No one is compaining of the symptoms described by @Belassi -

Professional Chemist / FormulatorNovember 11, 2018 at 7:41 am in reply to: Is this a real ingredient list?Crikey, our manufacturing is based in a developing country and the cosmetics compliance would never allow us to produce this legitimately. I thought Amazon was vetting cosmetics these days? How do they get away with it?

Professional Chemist / FormulatorNovember 10, 2018 at 6:18 am in reply to: Soap base face wash problemPerry said:I’d say the problem is using old technology like soap when you could be using better technology like less harsh surfactants..With great respect Perry, our business is built on cold process bar soap and liquid soap. Our certified GMP & Halal production facility is designed to produce old fashioned soap. We have our own brand, and 90+ % of our business is manufacturing for other brands locally and internationally. There is consumer demand for these products. If there wasn’t, we would not have invested the money we have to-date.The pH of our products is around 9.5 - 10. No complaints from customers. That pH should be below 8 is rubbish. Check out this table here of soap pH, includes both syndets and soap. -

Professional Chemist / FormulatorNovember 9, 2018 at 7:04 am in reply to: Stake in the business“They are asking of 15% ownership“….for that I would be setting some clearly defined and quantified sales outcomes as a result of their marketing activities. In my experience to date, a lot of there marketing characters steer well clear of measureable marketing outcomes.We have one of our private label customers asking to buy a stake in our production facilility business. The difference here is that they are “buying” shares. -

Professional Chemist / FormulatorOctober 26, 2018 at 9:24 am in reply to: liquid soap compositionWe do a lot of liqiud soap the classic way (oil + KOH). In response to some of the comments:“the foam is not that rich” - different oils have different characteristics and level of foam. For example olive oil = low foam, coconut oil = high foam. We blend a few oils to get the characteristics we want.“the pH is only reduced up to 9.” - ours are usually around 9.5 and we do not adjust with citric acid etc. Bring the pH down too far and you may then need to consider using a preservative. Will also tend to cause some seperation.“Classsic soaps are drying.” - a sign of poor saponification methods/calculation. Our customers say different. With many recipes we super-fat.” it is not a stable product.” - not in our experience. As part of our compliance requirement we retain product samples. After 4-5 years, products are still OK.“the traditional way- is that my clients want a natural (as far as it gets) liquid soap.” - our experience exactly. We also produce for other brands as well./“You can give your clients an inferior product based on tradition” - then I wonder why this inferior product is in such high demand. I will add however, this tradition is not easy. -

Professional Chemist / FormulatorOctober 26, 2018 at 8:59 am in reply to: “pH Balanced” wash-marketing hoax?We make soap, so I guess my opinions will be dismissed. Anyway, my tuppence worth.(1) I’m old scientist guy (pushing my 70’s) and in my time there was credible published research supporting the typers of claims made by Vermont Soap. This research is old, and has not been digitalised, so you will not find it on scientific literature databases. (wow, that now totally discredits me)(2) You may be surprised at the pH of many commercial soaps as shown in this extract below. We make cold process soap and they are usually around pH 9.5.(3) Old science: (i) a higher pH with soap facilitates the cleaning process (you know, one end attracts water, the other end dirt), (ii) the mantle regains its normal pH fairly quickly, and (iii) no long-term affects of high pH soap with normal skin. I have seen recent published research covering (ii) and (iii).(4) The higher pH does not require preservatives to be used, see ISO 29621 Low microbial risk cosmetics(5) So where does that leave me? We produce cold process soap for our own brand and other brands, and it sells well. These products have large long-established customer bases. The demand is there, so we keep producing. -
