Have you tried Anthocyanins (grape skin extract) for a purple color? https://www.iacmcolor.org/safety-of-color/natural-colors/anthocyanins/

You could ask your fragrance supplier for longer lasting fragrances but it still is probably unrealistic to have a fragrance last this long in a floor cleaning product because you really don’t want to leave a residue on the floor after it is cleaned.

To make a fragrance last longer you need to slow down the rate of evaporation so fast evaporating solvents like ethanol and isopropanol are not likely to help.

Are you sure it is your fragrance. Ethylhexylglycerin can cause emulsion stability in some cases.

Try a batch without fragrance and see if you get the same problems.

Thanks @DAS and @heraklit

We have already had one raw material impacted by the factory closures in China. We had absolutely no notice that the product which we were buying tonnes of per month would no longer be available. We were lucky that with a small amount of testing we were able to swap to a product with similar specifications.

I haven’t heard about the shortage in the 70’s but would love to know how bad it was?

Any idea what types of products the BASF factory was producing?

Particle size is another specification example that can play a big part in how the product performs for solid products. A very fine particle size for an exfoliant may be great for a face scrub but the exact same ingredient in a coarse particle size could do serious damage if used on the face.

I was looking through a supplier brochure this morning and there were about 8 different ingredients with the INCI of Magnesium Aluminium Silicate and these were all from the same company but had varying properties.

You may be able to incorporate glycol distearate in a cold process system when you use a pearlescent concentrate such as Euperlan PK771.

Wasn’t the “first ever all-natural preservative free face wash” just water? Very natural. 

I really hate these types of claims and marketing because even if this company have managed to create a “self preserving” formulation without traditional preservatives they make people think it is ok to make unpreserved products. This can be very dangerous especially when it gets propagated on the internet by the DIY crowd. (I am happy for people to try DIY - just do it safely)

I prefer to know what is in a product rather than what is not in it. I am looking forward to the ban on free-from claims.

I am having a look at some formulas with Pemulen TR-1 at the moment and quite like the sensorials.  My lubrizol representative suggested that I also have a look at Pemulen EZ4U. You can add fatty alcohols to the EZ4U version which might give you better sensorials. I haven’t had a chance to try it yet.

We have used colloidal oatmeal at 1% and use the same procedure as gld010 describes above (water phase/ fast mixing).

I have only seen it used in cream formulations at up to around 3%.

It depends on the product. Many cosmetics are also considered dangerous goods (e.g. aerosols. flammable liquids) for transport and would definitely require an SDS.

As Bobzchemist has mentioned it is definitely good business practice to have the SDS as you will likely need them at some point. You can usually combine different fragrances of the same product on the one SDS.

Hope this helps.

I would look at food gelling agents and food flavours. This article has a lot of information

I would recommend trying to get some Kaolin clay as this is main ingredient (other than water) in the formula you are trying to replicate.

I haven’t tried making this type of product but I seem to recall that in
clay mask formulas that the bentonite type clays are only used at
around 5% or less and the Kaolin is used in much higher amounts
(10-30%). Bentonite swells more/absorbs more water when compared with Kaolin so it will produce a thicker product. 

You could also try reducing the amount of bentonite clay used if you can’t get Kaolin.

Others may have more suggestions.

Hope this helps

Lotioncrafter has it available in up to 10kg lots. Also try searching for the INCI name as many distributors rename the products.

If you want 10kg or more just go straight to Schulke.

We previously had a deodorant that had cetearyl alcohol in it but no ethanol and we got push back from customers because we claimed it was alcohol-free.

Luckily the FDA has an information page that we could refer customers to regarding alcohol-free claims.

It shouldn’t be too hard to get a stable emulsion but you will have to do some trials.

You will probably have better luck creating a stable product using a combination of emulsifiers/surfactants (a blend of low HLB and High HLB) or even adding some ionic sufactants.

For the record Nonylphenol ethoxylate-9 is not a natural product.

Have you searched for formulas for this type of product?

I would also recommend working in grams and not volumes.

I would think that it is the ethanol in the witch hazel that is helping to solubilise the essential oils.

The reason you see it on a number of blogs is because people copy and paste from other blogs.

Can you use denatured ethanol rather than vodka to get around the restrictions?

I was looking up some old information on betaine today and came across the following information that may be useful to someone.

Betafin BP20 (betaine) is a co-solubilizer for salicylic acid and allantoin.

Salicylic acid

•Use
levels from  2  to 10 
%.

•
Solubility in water is 0.2 % at room temperature

•
Betaine was found to increase the solubility of salicylic acid to 5 %

Allantoin

•solubility
in water 0.7 % at RT

•
Betaine was found to increase the solubility of allantoin to 2 %

@DAS We buy the paste. I think it is a Chem Rez product (We buy through a distributor).

[ozgirl]

@Bill_Toge  and @DAS

Thanks for the information. I think a synthetic fragrance might be easiest in the long run.

[ozgirl]

We have switched to a paste version of Cocamide MEA which can be incorporated in cold process applications with no real problems.  Maybe you could investigate this instead.

[ozgirl]

@zaidjeber Thanks for the information. Unfortunately I don’t think that will work in my current situation but it is always good to remember there are different approaches you can take.

I have definitely seen soaps with “love” listed as an ingredient!  Glad they are finally catching up with some of these companies.

@Microformulation Eeewww!

My previous employer once had a possum fall into and drown in a batch of floor polish over the weekend.

LABSA is usually neutralized during the manufacture of the detergent.

Here is an example
