Are you referring to something like this product?

I’m not sure how it is done but it is very clever.

It depends on the fragrance and on the product type. Generally we use between 0.3% to 0.8% fragrance.

For facial products and leave on products (creams and lotions) we use lower levels of fragrance.

For wash off products like body wash we use higher levels.

[ozgirl]

I would just set it aside and wait for it to settle. You need to look at the mixing equipment you are using and maybe change to something with a slower speed option or preferably variable speed.

[ozgirl]

The regulations will depend on the country and this will also determine if the product is a cosmetic or a drug or both.

You need to determine what type of product you want to make and where you want to sell it to determine your regulatory requirements.

I am not exactly sure what you mean by “slick”

If you are referring to gloss and shine there are gloss meters that can be used to measure this.

If you are referring to if a surface is slippery you could possibly look at using a tribometer (used in determining coefficient of friction for floor surfaces) or similar.

I think the confusion comes from people being lazy and just leaving out part of the word.

If I want to shorten the name I usually just say CAP Betaine to help avoid confusion.

If in doubt when purchasing materials ask for the INCI name and CAS number.

If it is going to be a ready to use then you can use much less surfactant. The Stepan formula is for a concentrated product.

[ozgirl]

Normally raw materials are just tested against suppliers specifications. If the supplier says a 1% solution of the material is 6-7 you should be able to get the same result.

Do your QC methods differ from the ones the supplier uses? This could be the difference for the variances you are seeing.

Since you do not seem to be having any troubles with production and final formulation specifications, I would just record QC results for a period to get an idea of variances in your raw materials.

[ozgirl]

It is definitely looks like an ok starting formula. I personally would swap the sodium hydroxide with a chelating agent such as EDTA or a different alkaline salts such as sodium carbonate or similar

Is this going to be sold as a concentrate or a ready to use product?

[ozgirl]

@noelariel There are plenty of formulations that can be found by googling.

Your main problem is that you are mixing anionic and cationic surfactants.

[ozgirl]

Perhaps it is a translation problem and they mean grain alcohol.

Your best option is to talk to your fragrance supplier and ask for a fragrance that will be suitable in acidic formulations. Any good supplier should have this information.

It is quite difficult to formulate “natural” cleaning products that have the same physical characteristics as traditional cleaning products (foaming, viscosity etc).

First you need to define what you mean by natural? Are you looking for surfactants that are derived from plants and biodegradable? Sodium Lauryl Sulfate and Sodium Laureth Sulfate meet these criteria. What ingredients are you trying to avoid?

If you are looking for good starting formulations I would avoid looking on “natural recipes” websites and start looking on surfactant manufacturers websites.

Perhaps if you share your formula we can assist further.

[ozgirl]

Have you considered increasing the pH.

Do you have access to any non-ionic surfactants? 

[ozgirl]

I am assuming that you are talking about an industrial degreaser.

Have you tried googling for this type of formula. Have you contacted your raw material suppliers because they often have starting formulas.

I suggest looking at Prospector and at the following websites for starting formulas.

The ethanol is the active sanitizing ingredient. You would use a denatured ethanol here.

There is no surfactant included because it is not required. The ethanol is soluble in water so does not need to be solubilized.

Have a look at Lubrizols website for lots of information about hand sanitizers.

Perhaps you should read

https://chemistscorner.com/different-water-used-in-cosmetic-formulating/

Alum is only used to help remove particulate matter from water and you will need to remove the  soluble mineral salts (Calcium, magnesium, iron) for the best results.

[ozgirl]

A solubiliser like polysorbate 20 will improve transparency if the problem is with your fragrance. 

[ozgirl]

You need to use distilled or deionised water rather than tap water.

What is the activity of your triclosan? 15% seems very high. Is it supposed to be 1.5% or 0.15%. I think that Triclosan in hand washes is limited to 0.3%.

If you are having issues with transparency then this is probably caused by your fragrance and you could try adding a solubiliser as Perry suggested. I would suggest making a sample without fragrance and see if that is clear. Then you will know if that is what your issue is.

If it was my formula I would probably increase the Cocamidopropyl betaine.

Hope this helps

I have made a cream using Multifruit BSC (AHA/Fruit acids). The cream was very thick until we added the Multifruit BSC at 1-2% and then it thinned considerably.

Maybe try increasing the viscosity of your base cream and lowering your AHA/fruit acids to get a product that meets your requirements.

[ozgirl]

Not sure about your problem because I don’t make sticks but ethylhexylglycerin is a deodorant active and may help boost the deodorant activity of your product.

[ozgirl]

I always find a blend of solubilisers seems to work better than a single solubiliser when solubilising fragrance or essential oil in water. If you can add some ethanol to your solution you will probably use less solubiliser.

[ozgirl]

Thanks for sharing!

[ozgirl]

What kind of testing do you need for MSDS preparation?

[ozgirl]

The information I have on the Iselux brand of Sodium Lauroyl Methyl Isethionate is that

Iselux solutions thicken easily with electrolytes such as sodium chloride when used in combination with co-surfactants such as cocoamidopropyl betaine and sodium lauroamphoacetate.

So it seems that only a combination of these surfactants results in the salt thickening behaviour.

Cocamidopropyl betaine 30% solutions also contain salt at around 5% so this will contribute to the salt thickening behaviour.
