    We are based in Malaysia and can confirm that the best source of info is the ASEAN Cosmetics Guidelines
    In particular, and to answer your question, you should refer to the following Annexes of the ASEAN Cosmetics Guidelines:
    Annex II: List of Substances which must not form part of the composition of cosmetic products
    Annex III: List of Substances which cosmetic products must not contain except subject to restriction and conditions laid down
    Annex IV: List of Colouring Agents allowed for use in cosmetic products
    Annex V: List of Excluded from the scope of the Directive
    Annex VI: List of Preservatives which cosmetic products may contain
    Annex VII: List of UV filters which cosmetic products may contain

    Agree @Perry    We have entered the “Post Truth Era,” and largely fueled by social media. The borders are blurred between truth and lies, honesty and dishonesty, fiction and nonfiction. And especially in the cosmetics industry. As a scientist, it is frustrating, but I guess one has to face the reality and get used to being told you are wrong by an anonymous social media “guru’…. people don’t identify themselves these days.

    And the other side of the story. We produce shampoo by saponifying coconut oil, face wash using olive oil, and body wash using a blend of soya, coconut and palm oils. Yes, the pH is high. No, we see no need to reduce the pH.
    These products sell well, plus we produce OEM/Private Label for a number of brands.
    But the secret to these products is proper saponification. Many have problems getting it right, and the end product suffers as a result.

    From our experience one of the best repellents is Lemon-scented Eucalyptus (Corymbia citriodora) .  We produced a simple effective relellant using Corymbia citriodora.

    Well researched, for example, J Am Mosq Control Assoc. 2006 Sep;22(3):507-14.

    PMD, a registered botanical mosquito repellent with deet-like efficacy.

    “IME more people have issues with EO’s as they’re plant-based, than quality manufactured fragrances. “
    It has not been our experience. We manufacture face oils for our own and other local plus international brands. The market niche we capture includes many customers with issues surrounding manufactured synthetic fragrances. The co-founders of our company fall into this category of being affected by manufactured synthetic fragrances.
    I do not subscribe to the view that “plant-based” is 100% safe. It is clearly not the case. What we do is not accept any EO unless our QC Manager has approved the batch # CoA. The CoAs include an allergens analysis. In formulating we do a thorough analysis of the allergens and check that these fall within safe levels in the formulation.

    January 31, 2020 at 11:18 pm in reply to: Liquid Soap

    We do a lot of liquid soap using various combinations of saponified oils. Once saponified it will be solid, The next step is a dilution. The amount of water used depends on the oils. So for the first batches, it is a matter of trial and error to get the correct dilution. For example, with a coconut oil saponification using 18 Kg of coconut oil, in the dilution phase we use 15 Kg of water. In another recipe using about 12 Kg of olive oil, we dilute after cooking with 43 Kg of water.

    January 24, 2020 at 2:51 am in reply to: Anti-Pollution
    “anti-pollution formulas”…. conceptually, moving a bit away from the definition of a cosmetic in my humble opinion.

    Article 2 of the EU Cosmetics Regulation (Regulation (EC) No.
    1223/2009) incorporates the following definition of a cosmetic product:

    A “cosmetic product” shall mean any substance or
    mixture intended to be placed in contact with the various external
    parts of the human body (epidermis, hair system, nails, lips and
    external genital organs) or with the teeth and the mucous membranes of
    the oral cavity with a view exclusively or mainly to cleaning them,
    perfuming them, changing their appearance and/or correcting body odours
    and/or protecting them or keeping them in good condition.

    The wording “anti-pollution” is simply a marketing trend. Then you tack  “anti-pollution” onto a standard cosmetic formula, then make anti-pollution claims.  Brands who do this, in my opinion, are showing a sign of desperation.

    January 18, 2020 at 3:19 am in reply to: Cosmetic Regulations - EU vs USA

    We are located in Malaysia and our GMP production facility is ASEAN Cosmetics Guidelines compliant. We export to the USA and Europe. From our experience, the ASEAN Guidelines are certainly closer to the EU requirements. Follow the EU regulations, you’ll be compliant in most places around the world.

  • I would suggest you have someone help you with a Business Vision & Brand Guidelines. Based on your target audience and what you come up with in this branding guideline, the questions you ask will be answered. Important to be consistent in your brand messaging.

    November 30, 2019 at 1:44 am in reply to: Body Wash pH
    We saponify oils to produce liquid washes with pH around 9.5. We have been producing for about 20 years for our own label and OEM/Private Label. This pH has never been a problem.
    Going back to my research scientist days a long time ago, I was doing a lot of mathematical modeling for the skin. The mantle recovers quickly. Plus, the chemistry of cleaning favours a higher pH. It’s a wash-off product, so the body wash is not in contact with the skin long.
    Not a popular view. But that’s what we do.

    “Learning to make cosmetics and learning to SELL cosmetics require completely different skill sets. ” Agree 100%. We can make products, which consumes most of our time and resources, but a totally different mindset is required to sell. And, it’s not just the making, what comes with this is all of the compliance around GMP, product registration, etc etc. Go get yourself a god contract manufacturer.

    We make a lot of soap. And from what you have described, I would be looking first at the “fragrance: ‘red berries’ 3% .” Do you have a CoA for the fragrance? Is it the same as the previous CoA?

    We operate under the ASEAN Cosmetics Guidelines, and they have put together a series of modules. Our staff have a monthly working lunch woking through these. Als, it is a component of our GMP inspections, and the GMP inspectors want to see documented proof of staff progress in GMP training.

    Good point.
    As an Australian scientist I could never earn a good living, so moved into other areas. This is one of the issues. Another issue is the source of funding. Often the source will influence findings. And no, it may not be good science. This then raises the question of peer reviews of papers before they are published. What influences are are occuring here?

    Not sure why you are using Sodium Cocoate. We use this in solid soap formulations.
    For liquid shampoo we use Potassium Cocoate (saponified coconut oil).
    We have zero problems with cloudiness with Potassium Cocoate . No, we do not use a preservative because the pH is around 9.0.  Challenge Testing (PET) have demonstrated that preservatives are not required.
    Plus, this is backed up under ISO 29621:2017 covering finished cosmetic products. Identified products in the guideline do not require preseravtives and the application of microbiological International standards for Cosmetics commonly called “challenge test” or ISO 11930.

    We refuse to deal via alibaba. Instead, we buy direct from the manufacturer. It is not difficult to find these companies. Best approach is to ask others in your country for recommendations.

    @Docaashu, are you able to cite scientific literature indicating that “As a doctor, I know the fact alkaline pH is not good for skin. Alkaline property of soaps increase many health risks including fungal infections, eczema and psoriasis”?

    the decision followed to use double sterilized plates (those that are also sterilized in its secundary package) instead. More pricey, but problem solved!
    (Ok, these are a different brand and are plates instead of dipslides, but the medium and use are the same)

    What brand and product are you referring to?
    Thanks

    Thanks @ozgirl    All suggestions done, and all checked out. The sample results quoted in my post are from an SGS lab.
    I need to work through the distributor of Microcount dipslides here in Malaysia. Who then contact the Schulke technical people in China. The answer that came back was:
    In general I think the findings are comparable and reasonable as mikrocount duo is semi-quantitative and fast. The minimum determination limit is ~10^2 cfu /ml level. That means the SGS result 350cfu/ml is also in this minimum range. 
    The result is very related to the sample amount to the agar, that’s why for water testing the minimum determination is higher that high viscosity products such as solid/creams, which can be sampled more to the agar surface.

    Didn’t make a lot of sense to me, given the external lab results.
    Our QC Manager took the water samples for the Microcount dipslides plus SGS lab at the same time. So that eliminates a few variables.
    If I am reading the results correctly, the SGS lab results are well above the ND result from the Microcount dipslides. Others (include he Schulke technical people in China) have said differently. Therefore, I’m now asking here.

    We saponify coconut oil to make a shampoo product. The amount of oil remaining can be controlled via the saponification reaction, or adding oil after saponification.
