PEG-75 Lanolin
Hi All,
I have found decent information on PEG-75 Lanolin hard to come by. Having seen it in a few lotions and cream products I was wondering if anyone knows its main function and why people add it to their formulations?
Thank you so much

It’s an emulsifier with high water holding capacity and it’s “sebum-like”.

The industry mainstay (in the USA) is LANETO-50 from R.I.T.A. Corporation. This surfactant is the original water-soluble lanolin. It supports all the functions of lanolin only disperses in water easily. It would take a 2000 word article to fully explain its uses here.

@Pharma thanks for the information. Have you ever used it before?
@chemicalmatt thank you. I trying to get a full explanation from the supplier.
-
Sorry, nope (I’m not a fan of pegylated stuff).
-
Okay cool. Thanks for all the help
-
@Pharma - just curious, what is the main objections to PEGylated stuff?
-
@Perry Objection is the wrong word, it’s subjectivity.First: If you were to win a horse race in half the time on a farm nag, by avoiding half the obstacles, and without breaking into a sweat, then it takes the fun out of the game and I consider it cheating (even if it was a legal win).Second: Ever tried to reason with a religious person? I’m not religious but I’m telling you, PEGs have no soul.Third: Do I have any hard evidence or reasons holding up to a rational debate other than “It’s synthetic, it’s petrochemistry, it’s not sustainable”? Nope, I don’t.

@Pharma, PEGs are great. As a pharmacist you should appreciate them. PEGs can be used in semisolids and solids, with many good functions! I’m working on a study to increase the bioavailability of a drug. PEGs have soul and give life to other substances.

@em88 I haven’t said they weren’t performing great or anything in this regard, read my above statement once more very carefully
. As a pharmacist, I do use PEGs because of their many advantages but as a hobby formulator, I don’t like them. They feel like cheating because they take out the challenge and hence the fun with creating formulas. Regarding “soul”: As I also stated, there is no point in trying to discuss such matter. If they feel soulless to me, they simply do. If they have one for you, then that’s great for you and I don’t have any objection to your conception of the formulator’s universe. -
@Pharma - Thanks for the explanation. I’m reminded of something similar, there are those in the world who prefer film cameras over digital.
Debate about such things is mostly pedantic.
-
@Pharma you were complaining about PEGs existence as they are a bad thing. Is like saying, water is great and everything, but what’s the fun of surviving without it?
@Perry made a good point, I know of such people so I’m not going to comment anymore regarding this topic. -
@Perry You got it spot on! I wouldn’t call it pedantic but pointless. It’s as much a personal preference as is the taste of lets say durian (which I love BTW).@em88 Complain about their existence? You kidding? I said “I’m not a fan of PEGylated stuff” and then I compared PEGs with a winning horse (and IMHO they don’t have a “soul” but you don’t need souls to make cosmetics if you can use pixie dust instead :smiley: ). Obviously, if you like survival trips, then you don’t go there with a fully equipped trailer, a 4×4, and a machine gun but a tent, some basic equipment, and a fishing rod and that’s exactly the point of a hobby. C’mon dude, don’t play stupid: Not using water is way beyond reasonable!
-
@Pharma, you said “it takes the fun out of the game and I consider it cheating” if this is not complaining then I don’t know what to say.
I’m not so sure if you really understand the meaning of having soul.
Regarding the water expression, it was a hyperbole. Lol
Anyway, have fun formulating peg free products

Although I absolutely adore PEGs, and can’t imagine my formulation life without them, I understand that sometimes people have preferences that are hard to justify. For example I don’t tolerate most of animal derived products in my skincare. No logic behind it but I think that applying sheep’s sebum (talking about lanolin) on my face is super-mega-extra gross. Same about lard, tallow, and emu oil. I know that probably many lipsticks that I have contain carmine but prefer not to think about it. I am not a vegan. I like eating bacon, but I don’t want it on my skin :smiley:
-
Ah yes. I understood what @Pharma really means. I think I am rather similar to him. There are plenty of ready-to-whack stuff but I knowingly and deliberately chose the ‘suffering/stupid’ path kinda, sorta, as though, as if recreating the wheel. This is the “fun”, the thrill.
“Complain” refers to groan, repeatedly comment one’s dissatisfaction.
Complain long enough becomes “whine” or “whinge”.
Some people in my countries take ONE comment overly serious. A friendly suggestion becomes a dire complaint.
Perhaps my understanding of the English language is very bad.
Maybe comment=merely say/state=vent=complain=whine.
Toe-may-toe=Toh-mah-toh. -
Maybe it’s a generation problem? As a kiddo, I used to sweat and gasp for air while pedalling cross country with my mountain bike… today, people, easy-peasy, bolt past me uphill on their e-bikes. Not saying e-bikes are bad but they are like cheating. Got it @em88 ?@Cst4Ms4Tmps4 :smiley: You’ve got it!
