Perhaps you should look at something like Lamesoft PO65 (Coco Glucoside (and) Glyceryl Oleate) instead of oils. It will be much easier to incorporate.

Thanks @MarkBroussard for the reminder about the polysorbates.

Has anyone tried these preservative systems (or similar) with hydrolysed wheat proteins? 

[ozgirl]

What concentration of surfactants are you using? It won’t thicken if you have insufficient surfactants.

Have you also tried adding some cocamidopropyl betaine?

[ozgirl]

Have you tried salt (sodium chloride)?

[ozgirl]

You will need to provide more information if you want help. What surfactants are you using? At what percentages?

[ozgirl]

BASF also have a range of pre-mixed pearlescents (Trade Name - Euperlan). Unfortunately I don’t know where these are available to purchase in the US but someone might be able to help.

Are pearlized products still popular in the US? In Australia they have gone out of fashion and very few of the shampoos actually contain them.

I am also in Australia

You could try http://www.packmyproduct.com.au/

I haven’t used this company but they were suggested to me when I was looking for perfume bottles.

or http://www.plasdene.com.au/

They have pretty basic glass bottles for personal care / cosmetics but you might find something. I am not sure what there minimum order quantities are but I don’t think that they are very high.

Hope this helps

Have you tried Ali express instead of Alibaba. They have heaps of glass cosmetic bottles available with low MOQs. Try searching for refillable glass cosmetic bottles.

Where are you located because that might help people suggest suppliers that are closer to you to help save on shipping costs.

To keep the glycol distearate suspended you will need a reasonably viscous product so you will need to increase your viscosity. As David has suggested above try increasing your surfactant concentration.

Avoid high speed stirring because all you will do is create bubbles.

[ozgirl]

Pearlescent shampoos / body washes need a minimum viscosity and specific gravity to keep the pearlescent suspended. So that might be where the perception that pearlized variants are more viscous comes from.

[ozgirl]

You will probably need to add an ingredient that will help prevent grains forming.

You could consider ingredients such as
Cera bellina (INCI:  Polyglycerol-3 Beeswax),
Lipidthix (INCI Hydrogenated Vegetable Oil) or
Captex SBE (INCI Caprylic/capric/stearic triglyceries)

I work for a small company in Australia and have dealt with a couple of fragrance suppliers.

Most fragrance companies will have at least a 20kg minimum per fragrance and may require part or full payment up-front for fragrances especially since you are just starting out.

Have you tried Scott Aromatics in Sydney or CPL Aromas (distrubuted by Brentagg) in Sydney.

The Cosmetics Ingredients Review (CIR) and the European Commission both limit the amount of formaldehyde in cosmetics to 0.2%.

Have you looked at all of the different formulations and information on the Lubrizol website? There are a number of cleansing formulations with Ultrez polymers available on the website that would give you an idea of what might work.

[ozgirl]

Thanks for sharing.

It doesn’t take much more than a single study and/or some misinterpretation of a study to get something on the “bad” list.

[ozgirl]

Try the Ultrez 20 and see if that works. The quick start guide for the Ultrez 20 mentions using cationics so it should be ok.

Which carbomer are you using? Some are more resistant to electrolytes than others.

[ozgirl]

You can find information about your surfactants at the Cosmetics Ingredients Review website.

@Bobzchemist I have an article with some information on this Lindex system. I can email it to you if you send me a message with your email address.

[ozgirl]

Thanks for sharing! A very interesting article.

[ozgirl]

I have never seen Cocamide DEA used at more than about 2% in this type of formula. You can replace Cocamide DEA with Cocamide MEA.

[ozgirl]

Sorry this has happened to you. I hope you can at least get some of your money back.

@ledude

Only organic chemicals (carbon containing molecules) are tested in biodegradability tests and because water contains no carbon it is not included. Similarly sodium chloride would not be included. DOC means dissolved organic carbon and the measurement of this value is used in one of the tests.

The high cost of testing is another reason why smaller companies will often just claim that certain ingredients are biodegradable because the testing has already been done by the manufacturer. You can often get discounts if you test several samples at one time.

@EliseCortes I am in Australia and have only had to deal with this once to check the environmental claims on our products when were importing them into Canada.

Here is a link to the Environmental Claims Guide for Canada

http://www.bureaudelaconcurrence.gc.ca/eic/site/cb-bc.nsf/%20eng/02701.html

Section 10.3 deals with biodegradability claims and Annex D has a list of biodegradability tests (ISO,OECD and ASTM methods) that could be used.

Hope this helps

[ozgirl]

The claim “biodegradable” is really just a meaningless marketing term unless it is backed up by testing.

If your product passes one of the standard OECD tests (or equivalent) when tested as a complete product formulation you can claim that the product it is “Readily Biodegradable”. The OECD test results are a pass/fail outcome and are not qualified with a percentage value (even though they must meet a certain percentage of degradation to pass the test). The OECD tests do allow for some non-biodegradable material to be present in the sample so it is possible for your product to pass the test even when it contains some non-biodegradable ingredients.

If you have information from your suppliers that all of the ingredients or one type of ingredient are biodegradable according to the appropriate test then you could make a qualified claim like “Contains Readily Biodegradable Surfactants*  (* All of the surfactants in this product are classified as readily biodegradable according to OECD 301E)”. This claim is often used on products such as washing detergent powders where they consist of mostly inorganic salts.Only carbon containing materials are tested in biodegradability tests so water and inorganic ingredients can never be biodegradable.

I would stay away from claiming anything with percentages and just make claims that relate to test data that you have available. Personally, if I see a claim that 92% is biodegradable I would be thinking what is the other 8% of the product but if I saw a claim that the product was readily biodegradable and mention of a test method I would feel confident that the product would be ok for the environment.

Also, I am not sure where you are located but some countries (eg. Canada) have standards that relate to making environmental claims such as biodegradability.
