The GHS regulations allow for the flash point to be calculated and if the calculated flash point is more than 5 C away from the flash point limits it needs not be determined experimentally. This might be a good start to work out if your product is likely to be classified as flammable.However, this calculated method may not be acceptable for transporting dangerous goods.You would need to check the DG regulations. There are also provisions for substances that do not sustain combustion in the DG regulations. -
Check your local regulations because phenoxyethanol is generally limited to a maximum of 1% for cosmetics in most regions of the world.

I haven’t used the Polyox resins for cosmetic purposes but have used them in an industrial product. For this it was recommended to make a slurry of the Polyox resin in isopropanol and then add water to the slurry. This method worked well.According to your TDS (page 6) this method of using alcohols or glycols to create a slurry of the resin should work much better than just using water alone.Hope this helps

You are not using Ritamulse because you have your raw materials for this blend in different phases. Are you trying to recreate this emulsifier?The ratio of glyceryl stearate, cetearyl alcohol and sodium stearoyl lactylate in the Ritamulse SCG emulsifier blend is different to what you have attempted here.

Olivem 300 (Olive Oil PEG-7 Esters) is also recommended for bath oils and cleansing oils and helps to boost rinse off. I haven’t tried it but it might be worth investigating.

Benzalkonium Chloride is not compatible with SLES or any other anionics. You will need to find a different preservative if you want to use SLES.

Have you tried thickening the Potassium Cocoate without adding the CMEA to determine how much salt it takes to thicken. Maybe try looking for information on thickening liquid soap because that is essentially what you are trying to do.What is the active concentration of your potassium cocoate?CMEA is often pearl looking when dissolved in water with no other surfactants.

Have you considered the POLYOX Water Soluble Resins from Dow.Unfortunately I have only trialled them in non cosmetic applications so I can’t really help with which ones might be suitable but your Dow rep should be able to help.
-
My guess would be that you have tried to add too much extra and don’t have enough solid surfactants.Try taking out or reducing the stearic acid, cetyl alcohol, shea butter and coconut oil and replacing these with more of your solid surfactants (SCI and SLSa).Save the cetyl alcohol, shea butter and oils for your conditioner bar.

I would be asking for the marketing team to provide a brand name for the product they are referring to.CeraVe has ceramides in their micellar water but it is a clear product so I don’t think that the ceramides would create a pearl effect.

I recently saw a review (on the Making Skincare Facebook group) of the Dynamix blender for use making cosmetic emulsions. It is technically a hospitality emulsifier but should do the job and is a lot cheaper than the equivalent laboratory emulsifiers.

@CazP How old is your Geogard ECT? It sounds as though the Benzyl Alcohol has oxidised to benzaldehyde which gives it the almond odour.

Unfortunately I don’t know any websites in Europe (I am in Australia) but others may be able to help.You could ask for maintenance logs but they may not be available. It is the same risk as buying a used car. It is cheaper but you don’t always know the history.

Also look for second hand equipment that is often sold off when factories close.If you let us know your location perhaps someone can give better suggestions.

Sodium Lauroyl Methyl Isethionate (Iselux) can be thickened with salt but you need co-surfactants to achieve this. It doesn’t work for SCI Here is some information

I would assume that you would want a body “milk” to have a low viscosity.Fragrance can have a big impact on viscosity. Are you using the same fragrance as the sample with the higher viscosity?

I would recommend subscribing to Swiftcraftmonkey’s blog (http://swiftcraftymonkey.blog/blog) as she has lots of formulas for emulsified sugar scrubs with different emulsifiers. Generally I think most oil in water emulsifiers can be used in these products you just need to give it a try.In these types of scrubs you do not actually make an emulsion because there is no water in the formula instead the emulsifier is present to help with the rinse off of the oils (it may emulsify some of the oils at the point it is washed off with water).Hope this helps

I was intrigued by this as Dimethicone is commonly used in Australian lice treatments as well. The lice treatment kits contain the dimethicone treatment solution and also include a very fine toothed comb. These treatments are all listed as “medical devices” on the Australian Register of Therapeutic Goods rather than as OTC or prescription drugs.I did find one product available in the US that uses dimethicone (https://www.walgreens.com/store/c/licemd-lice-%26-egg-removal-kit/ID=prod6114800-product). Perhaps they are also being sold as medical devices rather than OTC to get around the monograph.

@Perry What a great achievement!My hobbies are Scrapbooking and Tap Dancing.

You definitely need to improve your emulsion stability or you will run into trouble. I am not sure where you are located but in many parts of the world temperatures regularly exceed 40oC especially during transport. It would not be good if customers receive a product that has already separated because the temperature was high during transport.If you post a complete formula for just one of the products that you are having trouble with you may get some help.

I have had success with Geogard 221 (Benzyl Alcohol and Dehydroacetic Acid). Just make sure your pH is less than 6.

Glad to hear that you are back!

It is possible that they are not meant to be there and are just recrystallised shea butter?Shea butter regularly forms grains when used in anhydrous products.
