After about six months, I haven’t see any color change in a shampoo with 0.5% orange oil and 0.1% tocopherol / rosemary antioxidant. Could usual antioxidants solve the problem?
Also citrus oils are very sensitive and need proper storage. -
Have any of you or your companies ever test a finished product to detect dioxane?
-
Thank you!
Here is another: http://nanoparticles.org/pdf/Salager-E300A.pdf -
Oh yes! Thanks Bill.

So what’s the HLB of various stearates (sodium, potassium, tea etc.)?
15? -
It’s advisable first, to sterilize the mud with gamma rays.
-
Usually various muds have tightening properties.

Yes, all the leftovers. We don’t buy any cosmetic - we use only the basics (soaps, shampoo, creams). And now I will start making and colognes also for us.

Why I see in many formula spreadsheets, ingredients in percentages with many decimal digits?
Examples:

Maybe because this counts at huge batches? -
Now my sister (age 49) learned that she is sensitive to beeswax or propolis!
Thats why EU authorities thinking to add about 200 more substances as allergens, that must be listed on our labels! -
Chamomile ess. oil doesn’t have any known allergen. I used a CO2 extract at very low amount. I haven’t see anything so far about allergies from chamomile extracts.

O.k. great article!

I tried 3 different browsers and can’t open the link.

Speaking about natural lip balms, my sister informed me that after she used my balm (olive oil, beeswax, chamomile extract, tocopherol) her lips swelled. She had suffered this also before with a balm from a large company. I searched google and found that this is something well known. It’s from beeswax - maybe the propolis, or ingredients from flowers like linalool?. But EU regulation don’t list beeswax as an allergen: http://ec.europa.eu/health/scientific_committees/consumer_safety/docs/sccs_o_102.pdf

Our difficult fight - perfect tips:
“You need to consider your market position against the herd. As an example of how to do it wrongly, I wasted a lot of time creating a super nice hand soap in a 250mL soap-dispenser (pump) bottle. The minimum price we could sell it at was $4.50 (because of the expensive package) and you can find similar items in a supermarket for around $1. Of course, the contents are SLS/SLeS/CAPB salt thickened and nowhere near as nice, but you know that price will beat customer benefit perception every time. It doesn’t make sense for me to design products like that because I can’t afford to buy 10,000 containers, 10,000 labels and 500 Kg of surfactants or for that matter put all that together and find markets for it - and I can’t get anywhere the price of the big companies.
So, it makes sense for me to design products that use expensive technologies so that the packaging cost is a small fraction of the overall cost and it is easy for us to make small quantities of expensive items as compared with large quantities of cheap items; and niche products that the big companies aren’t interested in.” -
This about Google is absolutely right! I think we are not here just to have company and chat but to ask about our real needs and problems on cosmetics. So if you have a problem, first you must search well the web or your books to find answers and then talk about it to the forum. It’s better to find the answer by yourself than to take it from another person…
Personally, the most of the needs that i have, are about performance of various ingredients in formulas. -
Three essential oils without allergens are Chamomile - Peppermint - Eucalyptus. But isn’t >5% too much?
-
I’m in the same work trying to achieve also these: good foam, thick, lots of slip, long-flow, luxurious hand feel, zero irritation to mucous membranes, kind to the scalp, and leave the hair easy to manage. I’m struggling now with sodium laroyl methyl isethionate - CAPB - Decyl gl.
-
I have tried these glucosides, and the answer is: decyl glucoside.

Thank you very much! ^

For conditioners: Conditioning Agents of Hair and Skin - Randy Schueller and Perry Romanowski
P.S. Chemist 1, could you please help me to purchase small quantities of ISELUX LQ-CLR-SB surfactant from a retailer somewhere?

We have very salty sea water here in my region, and also saltworks. People report relief or even healing of joints and muscle pains, and an improvement of some skin diseases but not anything special about acne. Maybe some reliefs are only temporary.

I combine Geogard 221 with Euxyl 9010 for my home shampoo - 0.4% each.
