    Hi Mike,

    Are you guys specialized in natural cosmetics sector? As I mainly work with natural ingredients like candelila wax, honey powder, oatmeal protein etc.
    And can you send me your price quote as well as shipping rate from Malaysia to US? Thanks !

    Yes, we are specialised in natural cosmetics. You can read more on this link:
    I cannot quote until I know more about your formulation, and we agree on MOQ.
    Shipping is dependent on weight and volume. Therefore I cannot quote until we have more detail of product, container type, weight etc, plus destination address and postcode.

    And look at the bottle type and colour of this so-called essential oil. This should tell you something straight away.

    August 7, 2021 at 12:31 am in reply to: preservative when is it needed

    I usually refer to ISO 29621 -

    Cosmetics — Microbiology —
    Guidelines for the risk assessment
    and identification of microbiologically
    low-risk products

    In certain product types, where extreme pH levels are reported, those considered pH ≤3,0 and pH ≥10,0
    do not require microbiological testing, including both challenge-test and end-product testing. At all
    other pH values (>3,0 but <10,0), a combination of pH and other Physico-chemical factors needs to be
    evaluated to determine potential risk.

    Yes, we use Mikrocount dip slides in a lab incubator during the development phases. And if all is OK, it’s then off to a certified lab for Challenge Tests.
    Who has the money to spend on a lab test during product development?

    In our microbial lab we use Mikrocount Combi tubes and a lab incubator for initial product development testing. Later we will send samples out to a certified lab for the preservative efficacy test.
    Over 10 years has worked perfectly.

    45 kg.  Dang.   Supplier contract with the jerks didn’t offer any help?

    No. They sent a follow-up sample, and on evaluation had a very strong and rather unpleasant back note that I think was the result of over-dosing with preservative. Then they blamed issues and contamination with their RO water.

    Been down that track…. no result. 
    That’s why I thinking it may be easier to dot ourselves. But can’t say I have any experience in this type of product…. often it’s the one that appears simplest are the ones that produce problems.
    Anyone here have experience?

    Good question. We operate a GMP certified production facility and most of our business is formulating and producing OEM / Private Label. To-date we keep the IP, but I am not prepared for the day someone wants to purchase a formulation. It seems to be a grey area. Looking forward to some responses.

    Cafe33 said:

    In reality, soap should be limited to cleaning the body. It is not recommended for hair. 

    For years we have been producing a liquid soap made from coconut oil. It’s popular, and sells well. But did take some time to perfect.

    mikethair said:

    My business partner and I have allergies to synthetic fragrances, so in our skin & hair care product business we stick with essential oils only. And we only buy from trusted sources… one I have used for around 30 years, and the newest, 10 years. All batches supplied with CoAs. 

    Are you willing to share your trusted sources?  Do they sell small pack?

    Of all the small pack resellers I have tried, I like New Directions the best.  But always open to a good supplier!  Can never have enough of those.  (Also shipping from Canada to Hawaii….adds up!)

    We are usually buying in around 30 Kg lots, so not “small pack.” Plus in our part of the world SE Asia, the suppliers are not the same as Cananda - Hawaii. Yes, we sometimes use New Directions (Australia) but you need to be careful in your specs…. we have fund they can sometimes tend towards things like “nature identical oils” which are in fact synthetic.

    We have found that many consumers have similar issues with synthetic fragrances. And many have gravitated to our brand because we don’t use synthetics. Same applies to our Private Label/OEM clients, which is now the largest income generator. None of this was planned or calculated. And when we started I was only aware that we could not work with synthetic fragrances due to our own allergic reactions.
    In summary then, there is probably space in the marketplace for both synthetic and essential oil fragrances. Most important I think is transparency.

    Under the ASEAN Cosmetics Guidelines we retain for one year after expiry date. At the same time we run parallel Real Time and Rapid (3 months) Stability Tests.

    Perry said:

    @mikethair - I understand this position and agree that it is nice to be able to communicate with who makes the product. It’s just very easy for an unscrupulous individual to start a beauty product line, cut corners, and produce something that might harm consumers.

    I have no great love for the big guys. But when it comes to safety, I think they are the better bet for consumers. 

    I think that the key is to look at the credentials of the “little guys.” Are they GMP Certified and regularly audited by the cosmetics compliance authorities? The qualifications and experience of the formulators? etc etc.

    We produce a liquid Castile soap made from extra virgin olive oil. We use a saponification vat purchased from the USA. I have experience consulting remotely to companies in Africa on how to purchase, set up, and use the equipment, and also on the formulation.
    Email me at: mikethair@indochinenatural.com      I should be able to assist with both parts of your project.

    September 18, 2020 at 9:26 pm in reply to: Formulas for Zimbabwean villager’s Micro Business
    I have experience working remotely with groups in Ghana, Tanzania, and South Africa. Our speciality in our GMP certified production facility on Penang Island is producing face wash, shampoo and body wash by saponifying commonly found plant oils. The advantage is that these do not require preservatives.
    With a group I’m working with remotely in Ghana, I’ve got them to the stage of producing 84 Kg batches of Body Wash using oils they harvest and produce.
    In my opinion, and from my experience (I’ve worked 40 years in development and poverty alleviation in many developing countries), it would be very difficult for her as an individual to make much progress. Better to think of forming a local collective.

    September 11, 2020 at 10:08 pm in reply to: Essential Oil % limit in leave on formulation

    If you are using essential oils then you should insist on a CoA from your supplier for each batch number you purchase (it’s part of your GMP compliance). The CoA should have an allergens analysis. Using this allergens analysis for each oil, then you should do an analysis of the total allergens for your finished product. Then check if the level of each allergen is below published upper limits.

    September 11, 2020 at 10:01 pm in reply to: Preservative for pH 9-10 liquid soap

    If the liquid soap has a pH 9 - 10, a preservative is unnecessary. Refer to ISO

    29621 “Cosmetics — Microbiology — Guidelines for the risk assessment and identification of microbiologically low-risk products.”
    We have a GMP Certified production facility producing a lot of liquid soap, and export globally. These products are Notified with cosmetics authorities and all the necessary testing is done in our in-house labs and verified by external labs.

    We use Ohaus Troopers and have found them very robust and reliable. And we have a company that services and calibrates them annually. We think this is important.
    If you have someone who can do service and repairs, and are not too expensive, I’d give it a try. From past experience, the issues you have described may be easy to repair, if you know how.

    July 17, 2020 at 8:07 am in reply to: Are preservatives obsolete?
    If you are making true soap (liquid and solid) by saponifying plant oils, then preservatives are not required. ISO 29621 “Cosmetics — Microbiology — Guidelines for the risk assessment and identification of microbiologically low-risk products” covers this.
    We produce these types of soaps in our GMP Certified production facility. As part of our GMP standards for 10+ years, we have performed Challenge Tests on these soap products, and they are always negative. When we export to the EU, they recognize that microbial data is not required for these products.

    In my opinion, it would be a challenge if attempting this if your production area is not GMP certified.  Ours is, and we work with this size container on a daily basis.

    Thank you. How exactly do you do it? What equipment do you use?

    It depends on the ingredient. If liquid, it can be simply poured into a stainless steel pot for weighing. If more solid, use a suitable scoop. You should read up on GMP processes and conditions to understand the conditions under which we operate. After dispensing from these containers we have our In-Process Quality Control room where samples are taken and tested, and of course, before the final product release our QC Manager will do a series of lab tests. These include microbiol tests in our on-site microbiology lab.
