Dear Kendall Jenner fans - which pdrn Kendall do actually use? 😍😍/s
Does Kendall use L'Oréal pdrn or Anua pdrn? 😍😍😍

So, inspired by this u/acornacornacorna comment about "spectrum of education of cosmetic chemists" https://www.reddit.com/r/EuroSkincare/s/LRdO6jIvj0
I want to make callout about lack of education which javon presents , which is included in spectrum of cosmetic chemistry
We know that he is popular, his main point is that "he is cosmetic chemist"
However, as someone who have some knowledge about formulations of home care products (surface cleaning , dishwashing, laundry, and to some extent about biocides)
When I saw video of javon, where he tried to prove "as cosmetic chemist" that dawn powerwash is "dawn dishsoap+ alcohol" ( https://vm.tiktok.com/ZN8rBK2Cg/) and it's overpriced, I already known that he doesn't know what he talk about
Dawn power wash (and fairy power spray skip the soak) are based on :
Surfactants
Solvents,
Chelators
And alkaline pH
It's more like kitchen degreaser than "dish soap with alcohol"
Dawn ingridients are :
Surfactants: c10-16 alkyldimethylamine oxide, hexyl ethoxylate, lauryl glucoside, sodium xylenesulfonate.
Solvents: alcohol, dipropylene glycol butyl ether, ethanolamine, water.
Chelators: sodium citrate, tetrasodium glutamate diacetate,
Texture adjuster: ppg-26
Preservative- phenoxyethanol
And scent
The heavy-duty version of powerwash lacks alcohol in place of bigger amount of dipropylene glycol to my knowledge.
Fairy ingridients:
Surfactants:
Lauramine oxide, undeceth-10, Dodecylbenzene Sulfonic Acid
Solvents: water, dipropylene glycol butyl ether, ethanolamine,
Chelators: none
Ph adjusters: sodium hydroxide/lye, sodium carbonate/washing soda, sulfuric acid
Texture adjuster - polyethylene glycol
Fragrance
The pH of dawn power wash is 10.6 - 11.4 via sds
The pH of fairy power spray is also 10.6 - 11.4 via sds
While pH of fairy max power hand dish soap liquid is 8.4-9.4
And pH of dawn platinum plus power suds liquid is 9
So both power wash and fairy skip the soak power spray ARE MORE ALKALINE, and this DOES make a difference
While fairy lacks one of really important things which are in dawn, chelators, which really help to a- boost surfactant effectiveness due prevention of calcium/magnesium interacting with surfactants
And there is some evidence that suggest chelators helps removing carbonised / burnt off food and grease,
at the same time the another really important ingridients aka solvents are pretty much exactly the same, I'm not mad about lack of ethanol in fairy since dawn power wash heavy duty also lacks ethanol
The surfactant systems in dawn and fairy are completely different
But surfactants in both versions are simmilary effective in removing grease.
So claiming that dawn powerwash is "dish soap with alcohol in spray bottle" is scientifically incorrect, and using cosmetic chemist authority to claim that pisses me off
While dawn power wash have alcohol, it's not the main star of dawn,
The main star is dipropylene glycol butyl ether (brand name dowanol dpnb) and ethanolamine (to be more specific p&g uses monoethanolamine afaik)
This is pretty much basic knowledge in cosmetics chemistry which javon should know "as cosmetic chemist"

First of all, except 5% bemotrizinol it uses 3% avobenzone, 5% octisalate,
And not fda recognised chemical SPF boosters which works simmilar to chemical sunscreen, aka ethylhexyl metoxycrylene, and butyloctyl salicylate
Typical shady UV 🤡
I saw that detergent on biggest bullshit factory, aka TikTok,.
And god, their marketing maked me laughing for hour.
https://www.guestsonearth.com/collections/laundry/products/laundry-detergent
ChElAtOrS aRe ToXiC,
Meanwhile ingridients list: sodium citrate, sodium gluconate aka... chelators.
So you are saying your product is toxic? Since it contains chelators? 🤡
Also - the negative of enzymes is that they can degrade natural fibres so we used corrected blend of enzymes that clean without compromising integrity of fabric.
Ummm, only protease and wool? And too big cellulase dose on cellulose fabrics, but at the same time you use that enzymes which "compromise" integrity of fabric
Also, the dosing- they claim 5 ml is enough to wash whole load.
Yeah, only if you believe in homeopathy, because that's homeopathic dose.
And also - no preservatives: do you wanna be true the laundress 2.0, and also wanna have recall because of lack of preservation and microbial contamination
So, I was looking at my pharmacy for new sunscreens, and I found that uvage had new packaging,
I checked ingredients, and they are different
New uvage have :
Uvinul t150
Avobenzone
Tinosorb s
Mexoryl Sx/xl
Uvinul a plus
From skincare actives:
Lha
Matrixyl 300
And grifola frondosa extract
Still have Netlock technology
Old one was Shaka fluid dupe
Had octisalate, avobenzone, uvinul t 150, tinosorb s, mexoryl Sx / xl
From actives it had 2% niacinamide, rice peptides, viretoscella ferment, and 1% Vit e
Cotton under electron microscope,
One washed in high quality detergent (tide free gentle)
And one washed in "leading free detergent" - aka in all free & clear
Yeah, scrud forming , not washing at all.
Totally useless yet still the most popular 🤡

He claims that in us cold water setting is 30°c/86°f
Meanwhile from p&g study https://aocs.onlinelibrary.wiley.com/doi/10.1002/jsde.12467 : ""Lipophilic soils, including sebum transferred onto fabrics from skin, are more difficult to remove in colder wash temperatures (e.g., 15 °C versus 30 °C), while the rheology of several food greases becomes more similar to that of adhesives at 15 °C (Stenger and Vinson, 2018). In the United States, 44.7% of households wash over 50% of their laundry loads on a cold-water setting (P&G unpublished internal data based on n = 54,136 loads of laundry done in 304 households in the United States from 2018 to 2019). A cold-water setting is defined as 16 ± 4.2 °C (AATCC Committee, 2016 - https://www.scribd.com/document/262242086/Aatcc-Monogram-m06 ). Although washing on cooler water cycles decreases the energy use associated with consumer laundering, it can make odor removal from fabrics more difficult because sebum residues harden (the viscosity increases) at lower temperatures such as 20 °C (Burton, 1970; Butcher and Coonin, 1949). This problem is exacerbated by the fact that 24% of laundry loads are underdosed (P&G unpublished internal data based on n = 37991 loads of laundry done in 340 consumer households in the United States in 2019)"
So, in us , cold water setting IS NOT 30°c/86°c, it's a freaking 16°c /60.8°f
AATCC says that warm water setting in us reality= 30°c /86°f
In Europe 30°c is cold, but let's not forget that all EU washers have built in heater, while in us machines depends on water temperature by mixing cold and hot water, and if even washer have heater built in, it's mostly to keep water temperature.
aka domol quick and cool,
I checked scent, meh, not bad but not my fav
have dnase, mannanase, cellulase
no protease at all
https://ec.europa.eu/safety-gate-alerts/screen/webReport/alertDetail/10118691?lang=en
So
We got safety alert about fake uvmune oil control fluid
Fake uvmune oil control fluid sold on Ali
With no SPF at all (in test SPF lower than 2)
This fake look really fake,
But what about better looking fake products?
To prove that I'm not Loreal shill ;)
Ok so, polish Rossmann now have testers of that toner/essence, I tested on hand, I loved texture, and because was on sale I bought it (26.99 pln/6,50€ , normally it cost 46.99/11euro)
and I started using for about week now.
Some context, my skin is combination into more oily side, with some seb derm around Nose and Brows, acne prone/prone to comedones
And I must say, this essence is REALLY good, hydrates skin REALLY well, calms skin.
Addition of piroctone olamine controls seb derm.
Even though it does have isopropyl palmitate it didn't break me out at all
It totally replaced moisturizer for my skin for now.
So I can cleanse skin (Eucerin dermopure clinical aha bha pha)
Put this essence,
And in am put sunscreen (CeraVe mattifying fluid)
And in ready
For 11€ I wouldn't buy that tbh, but for 6,50? HELL YES.
To this PSA I got inspired by this post https://www.reddit.com/r/laundry/s/VVtRGTmHgl
Where someone used oxygen bleach containing product to wash their blacks on regular basis.
Ok so, oxygen bleach is colour safe, but it safe when u use it on occasional situations, not when used regular
While oxygen bleach (hydrogen peroxide) does not cause bleach spots on color fast things unlike chlorine, and its less strong than chlorine in causing fading
With repeated use it will fade things for 100%
With sodium percarbonate in powdered oxygen bleaches the problem is also carbonate part which leaves residue casuing fading as well (but residues can be removed with rinse refresh/citric acid)
oxygen bleach also works on chromophores (aka color bonds) but more gently than chlorine bleach
And temperature in which u wash blacks with oxygen bleach dosnt matter because in colder water spc still works BUT to some extent, spc still releases hydrogen peroxide but slower.
So even though the release of hydrogen peroxide is slower it's still contribute to fading.
And if u use activated oxygen bleach with TAED, it's even stronger in causing fading than hydrogen peroxide alon,
In general peracetic acid created from reaction of TAED and hydrogen peroxide is stronger oxidiser than hydrogen peroxide and can cause fading/bleaching stains like chlorine when applied undiluted
And thats makes the power of it - u dont need a lot of peracetic acid to work- to remove bleachable stains, disinfect etc
So for darks - no oxygen bleach at all, unless u need to disinfect from pathogens resistant to quats (but here u need to use activated oxygen bleach with TAED which ofc gonna fade them but it's still better than bringing c.diff to home ) or u deal with biological stains like shit vom cum blood piss etc
If u srsly need to use oxygen bleach on colored things to just remove some stains and want lack carbonate residue try clorox colorload liquid which a- lack optical brightners, b its based only on hydrogen peroxide
Someone posted about AI graphics on isana sheet mask.
But is seems that whole Rossmann team is based on AI I just 7 ai generated pics just on start page of polish Rossmann app 💀🤡
So, recent discussion about discontinuation of tide odor refresh and addition of odour removing anti oxidant methyl di-tert-butyl hydroxyhydrocinnamate
To classic version of tide free gentle liquid
https://www.reddit.com/r/laundry/s/h0FcazSGdr
Maked me searching more about this anti oxidant
And than I Finded this https://tide.com/en-us/research/odor-after-washing
And what I Finded interesting (since chelation is one of my fav chemistry topic)
Tide claims except sebum residue, Edna residue
Autoxidation of sebum triggered by copper catalyst contributes to stink from fabric
" '2.2 Pathway B: Catalytic Autoxidation of Sebum:
Even after washing, residual sebum remains on fabric. This sebum, which contains unsaturated compounds like squalene and various fatty acids, undergoes autoxidation. This is a chemical chain reaction that breaks down large, non-volatile sebum molecules into small, volatile, and highly odorous molecules (Miracle et al., 2020). This reaction is dramatically accelerated by the presence of catalytic copper (Cu2+) ions, which are common in household tap water, sweat, and soil (Miracle et al., 2020). The presence of copper significantly increases the generation of malodor molecules on fabric"
https://aocs.onlinelibrary.wiley.com/doi/10.1002/jsde.12467
P&g did this study in which they tested mix of antioxidant (cinnamate) with copper chelator ( diethylenetriamine)
And they compared smell of fabrics washed in this mix to fabrics washed in lipase containing detergent (Persil pro clean 2in1)
And they surprisingly find that this mix was kinda effective at preventing Bo on fabrics
So, it seems except lipase, good quality surfactants in good ammout, heat, mechanical action, antioxidants, oxygen bleach, protease
Chelation of metals such as copper/iron/ manganese
Also contributes to prevention of smell on fabrics
So, more calgon can be one of methods preventing bad smell on fabrics since it's pure chelators
I didn't saw this discussed anywhere so I'm making this post.
I saw that recently (ok not so because this is about year in cw but I saw that now on website) chemist warehouse got Nivea serum .
And to be surprised it's the one with thiamidol
To people who don't know- thiamidol is beiersdorf patended resorcinol derivative, very effective tyrosinase inhibitor.
And in systematic reviews/ meta analysis it has been shown to be very effective (pretty simmilar to hydroquinone) at treating hyperpigmentation,
Without side effects like bleaching skin too much, without irritation etc.
Europe/south America /USA/ Canada had thiamidol products for a while.
But Australia got 1 thiamidol product recently
https://www.chemistwarehouse.com.au/buy/170327/nivea-luminous-630-skin-glow-serum-30ml
So yeah, they gonna probably be first launching formulations on us market
Inspired by recent post about new super "innovative" avene serum I decided to compare prices of this serum now where I live (Poland) to prices in Priceline.
The difference in prices is CRIMINAL
To compare prices I choosed 2 most popular pharmacy chains - Ziko and Gemini .
Gemini now have discount so serum costs 124 pln/ 47 AUD.
Ziko have this serum for 170 pln- 64 aud
Meanwhile priceline- 99 aud/262 pln.
The markup/tax for Australia compared to Europe IS INSANE.
2X more expensive 💀
New account, pretty empty, at the same time promotes dad mode product everywhere
Pure guerilla marketing
Ac*ive brand who?
No messy capfulls 😌
