Pharma said:Abdullah said:…My question is, does viscosity of lipid phase has any effect on emulsion stability?
…Yes. Purely stability-wise, higher inner phase viscosity makes an emulsion (or rather the oil droplets therein) more stable regarding coalescence and Ostwald ripening.
Thanks.
I am currently using petrolatum+shea butter too. -
@MarkBroussard that is good to know.
As rose absolute as 50% phenethyl alcohol and in my emulsions 0.1% rose FO is enough to fragrance the product i thought 0.2-0.3% phenethyl alcohol would have the same fragrance powder with extra preservative boosting. -
What ingredients does it have?
Does it have water?????
-
For solid ingredients, you can mix them better and easier when they are in liquid form. In solide form you cant mix them very well and it will be very difficult to mix in large scale.
Think of it as 100kg, can make balm in cold process?

@PhilGeis which type of plastic does it migrate more? HDPE or PET?

Graillotion said:Abdullah said:This does NOT carry into the final product, as far as I can tell.
@Graillotion What do you mean by this sentence?
That means….at .35% inclusion rate, I do not smell rose.
Aahhaa
So it will increase the cost a lot because fragrance oil at 0.1% is enough for emulsion smell.Thanks a lot

@Graillotion What do you mean by this sentence?
-
What ingredient does it have and at what percentage?
Also do both of you use the same fragrance?
-
@Graillotion thanks for input.
As it work as preservative booster too and i can remove the word fragrance from LoI but still have a beautiful fragrance, a bit extra cost will be ok.As i will import it from another country, i wanted to have an estimation that what percentage of it will have about the same smell as 0.1% fragrance oil so i can calculate the in use cost better.
Have you used it in an emulsion without fragrance oil?
-
No it doesn’t cause hair loss.
I use 2% and it is completely fine.
The hair loss may be from another ingredient in your shampoo or not from your shampoo and from something else that those customers are using.

Cleanser removes everything from surface of your skin and makes it clean.
Aloe Vera butter and and glycerin will not work as cleanser.Emulsifier makes oil and water combin.
Glycerin will not make oil and water combin.These are your imaginations????

@Pharma thanks a lot

@PhilGeis thanks

emma1985 said:I’ve had to switch the 500 from 350 because I can’t find 350 in stock. Haven’t tried 500 yet but my understanding is higher cps is actually more effective at delivering the properties that we look for in silicones (soaping prevention, increased play time and glide, etc.) I could be wrong though.
Higher viscosity is better only as skin protectant. Lower viscosity is better for everything else.
5 cst is best because lower that that is volatile. -
Thanks all

emma1985 said:DaveStone said:Perry said:Sun damage is not a myth. Just look at the skin of people from Arizona or Florida vs people from Minnesota. If you’re not from the US these are sections of the country that are sunny (Arizona / Florida) and less sunny (Minnesota). People in sunny places have “leathery” looking skin in my opinion.
So, if you care about having skin that doesn’t look aged or weathered, wear sunscreen. Theoretically, sunscreen use should also protect against skin cancer. However, the data on this is much less convincing.
Sunscreens are not regularly added to moisturizers because it would make formulas more expensive without providing a benefit companies could claim. Also, the ingredients are drug actives (at least in the US).
Never been to Florida or Arizona, but I have been to Southern California. I hadn’t noticed anything different about people’s skin other than that it was tanner. If I looked closer, I’d probably see more wrinkles. Tanning is bad for the skin. I always hated when someone would tell me to “get some color”. I would tell them I’d rather look like Casper than the Cryptkeeper.I didn’t mean that sun damage in general was a myth…just damage when out of direct sunlight. But that article helped clear it up.Tanning is literally sun damage, by definition. It is the skin’s physiological response to the trauma of UV exposure. UV induced aging of the skin happens over time. Those tanned Southern Californians will be looking rough as hell in a few decades. That’s how it works.
a few decades? I think in a few decades everyone will become old and look like hell.I’ve been wearing sunscreen every time I leave the house for 7 years. That doesn’t mean my skin is necessarily less wrinkled than those my age currently. so what was the benefit? But it almost certainly means my skin will be less wrinkled, less pigmented, more elastic and more firm than my peers 10 years from now. i think this is just how you want it to be. but in reality after 7 Years of sunscreen use your skin was not different that others in your age so it will not different after 10 years too. Also, my chances of developing skin cancer will be exponentially reduced compared to my peers who didn’t wear sunscreen. how much does sun exposure increase the chance of skin cancer? I mean by what percentage?

emma1985 said:The monk is 30 years older than the Native American woman. Wear sunscreen folks. If you don’t care about visible aging, wear it to protect your skin from skin cancer, which, contrary to popular belief, can be fatal!!
Did (a) use sunscreen? No.
In sun exposure he was like everyone else (most of the time indoors). We are not exposed to direct sun even 30 minutes a day.About (b); most of her life means more than half, means more than 12 hours per day outside. Tht is not how majority of us live.

@Microformulation @emma1985 thanks.
Is this product patented by this company or it has other manufacturers too?

Pharma said:SaraLee said:I’d love to get my hands on some, but as a hobbyist I haven’t been able to find a small batch source. If you know of one I’d be forever in your debt! How about sodium phytate?I’m in the same position ;( .Anyway, phytate is worse. Small amounts of EDTA should work even if there’s some incompatibility.HEC should work.@Abdullah Slow cool down or hold heat for some time (one of the few exceptions where this might pay off for small batches).This is not just due to the (co-)emulsifiers within the oil phase which need to get to the interface but also because coco glucoside is a polymeric and therefore a ‘slow’ emulsifier which needs some time to ‘get in place’ and if the oil has already hardened too much it can’t incorporate into the interface.
@@Pharma thanks
1. Should we keep the temperature the same as it was at start of emulsion for longer or we should cool the batch slowly after emulsion is made to take longer to cool down?
2. During this longer period of cool down after homogenization, should we use homogenizer for longer for longer, slow agitation for longer or it is ok to be still and not mixing?
-
Pharma said:That amount of wax results in solid oil droplets. Depending on the speed of cool-down, the emulsifiers won’t have a chance to organise properly.These solid oil particles will have a positive charge which plays well with honeyquat but not so much with xanthan gum. I suspect that these two polymers will ‘clog’ around the oil particles and allow them to flocculate.Personally, I would use a non-ionic polymer instead of xanthan.Natrasil can go into the oil phase and might help making these less high melting and more flexible.As mentioned above, PEG-100 stearate should also help and you might even use it instead of coco glucoside.
@@Pharma which one is better if an emulsion has solid oil droplets?
Fast cool down or slow cool down?
And cool down to which degree Celsius?
-
EDTA is also incompatible with cationic surfactants

Thank
