I cannot find any information on Euperlan PK 777, but Euperlan PK771 and Euperlan PK 710 both contain sulfates (sodium laureth sulfate) so you might want to check this first.

Sabo is an Italian company

The information came from Kemcare’s .com website. I assume that the Mexican branch of Kemcare uses the same principal suppliers.

On the Kemcare website the pearlisers are called Saboperl and one of their principal suppliers is Sabo. That should help you identify which one it is.

@maddies We do all of our physical stability testing ourselves but there are labs out there that can do this for you. I am not sure what your situation is (homecrafter, small business etc?) but maybe check out New Directions as they offer these services.

I have not tried Geogard Ultra in a conditioner so unfortunately I cannot offer any advice on usage levels.

I also came across the disclaimer in the Euxyl PE9010 literature regarding rinse off products that a high load of ethoxylated surfactants result in a loss of efficacy. I asked one of the sales rep for Schulke about what they consider a high level of ethoxylated surfactants and he told me around 5% was considered high.

The Euxyl K701also contains Phenoxyethanol and Ethylhexyglycerin (along with Benzoic Acid and Dehydroacetic Acid) and is suitable for surfactant preparations so this may be what your competitors are using.

The good thing about Schulke is that they will test the efficacy of their preservatives your formula for you.

Hope this helps

@maddies There are a couple of formulators on this forum that are from Australia (myself included).
Here are some websites that might be of interest in learning about how cosmetics are regulated in Australia.

I would recommend that you check out http://swiftcraftymonkey.blogspot.com.au/
to learn some basics about cosmetic chemistry and emulsions etc before trying to tackle a more difficult product.

We have used Geogard 221 (Benzyl Alcohol + Dehydroacetic Acid) in some of our creams/lotions with good results.

It is very difficult to get a sulfate shampoo to have similar foaming characteristics to a sulfate based formula.

We use Versathix (Croda) to thicken our sulfate free shampoos with good results.

Have you tested your shampoo without the extracts and fragrance to see if any of these are causing the itching?

Thanks @Mike_M

Cetiol Sensoft is a fast spreading emollient (spreading value 1900mm2/10min) with medium polarity and a viscosity of 5mPas @20oC.

We used this emollient a number of years ago when it was made by Cognis but were forced to change as we were unable to meet the high minimum order quantities imposed by BASF. We changed to caprylic/capric triglycerides with only slight difference in the feel of our lotion. You could probably replace the Myritol 318 with Sensoft with not too many issues. Just check out the minimum order requirements with your distributor.

Thanks @Belassi

Thanks Perry.

I am going to try it. I was just wondering if anyone had tried it before and had problems.

[ozgirl]

Just checking in to see if anyone has any experience in this area.

[ozgirl]

What type of product are you making? What is the problem they are causing?

These ingredients are used together in Johnson’s baby lotion (with some other multi-functional preservative/antioxidant ingredients) which strongly suggests that they can be used used together.

Have you tried adding each raw material separately to see if it is just one of the ingredients that causes your problem rather than the combination?

[ozgirl]

As with many of these certifications/marketing tools you could probably get the same  benefit by putting a picture of a leaf (or similar) on your label. It is probably not really worth the money unless you are specifically targeting EWG supporters as customers.

[ozgirl]

I take a similar approach to Bill_Toge and Mark Broussard with lots of research and thinking and less time doing but if I need to make a dozen samples then that is also fine.

I have definitely noticed the trend that most people who have to buy their own raw materials will definitely be resistant to doing more trials.

The availability and size of samples depends on the supplier. I have had some suppliers give me an entire range of samples that might be useful that I didn’t request and then some suppliers will give you 50 grams of a sample you need to use at 5-10% in your formula.

I did have one raw material that we got a sample of and tested. When we were ready to buy it the supplier had discontinued the 20kg pack size and we could only buy it in 200 kg drums. As the product it was going into was a one time product we didn’t have need for that much, we eventually convinced the supplier to just send us 40 x 500 gram samples which they did.

[ozgirl]

Is this supposed to be a clear product or a pearlescent one?

My guess would be the SCI. The solubility of it is temperature dependent and when you cool it down it can become opaque and if your viscosity is not very high it will separate.

Maybe try Sodium Lauroyl Methyl Isethionate instead if you want a clear shampoo.

If you are using pure H2O2 solutions, any hydrometer that measures the specific gravity of a liquid can be used and then you can convert the SG to concentration.
http://h2o2.evonik.com/product/h2o2/en/about-hydrogen-peroxide/basic-information/calculations/pages/calculate.aspx

You can get hydrometers from any lab supplies store. Just get one that matches the range of SG values that you will need.

@”Fastfiller ” We have no problems buying small amounts of tubes.

My comments were just pointing out issues smaller companies and start ups run into with tubes.

[ozgirl]

I did a few trials with Spectrastat in a shampoo and body wash and had good results but in the end decided not to go ahead with it due to cost. I liked this system because it was suitable over a range of pH values.

I would stay away from Spectragard with the isothiazolinones as they are getting a very bad name also. Isothiazolinones are not recommended for leave on products.

Unless all of your products are self-preserved (aka “preservative free”) I don’t think it is is necessary to use a preservative free system. It just usually adds extra costs for less preservation.

We use Geogard 221 (Benzyl Alcohol and Dehydroacetic Acid) in our creams with good results.

[ozgirl]

Absolutely agree with this. There are some so-so ideas out there with brilliant execution that are making lots of money.

[ozgirl]

No issues with preservation but it will probably depend on what preservative you choose.

[ozgirl]

We use that product normally in conjunction with Eumulgin SG (Sodium Stearoyl Glutamate) to make creams and lotions and make batches of 200 to 400L with no problems.

I seem to remember most of the starting formulations for that product included a second emulsifier like Eumulgin SG.  I also think that the Emulgade PL 68/50 is referred to as an emulsion base rather than a complete emulsifying system so you may need an additional emulsifier to get good stability.
