I thought that she was asking why her acrylic product yellowed not her brush. 
I've never had a brush yellow, my brushes have always been Russian sable and 
I've never seen them turn yellow. Maybe I'm not understanding what you mean. Do 
you mean a contaminated brush causing yellowing acrylic? 

I was not saying that the cause of yellowing acrylic is due to ALL of the 
things listed happening at the same time, it can happen if just one of the 
things listed happens. Cleaning you brush in monomer and then putting a cover 
on it is the same as not cleaning your brush at all. Entity makes a brush with 
a cap that has a hole in the tip so that the liquid can evaporate out of the 
brush so that it should not hold contaminates in the brush. Notice I said 
"should not". I have used the Entity brush for many years with the cap and have 
never had a product contamination problem from the brush. I'm not saying that a 
contaminated brush is always the problem, I meant that it could be the problem.

My list is by no means compleat, this is just a list of what I have experienced 
or what I've been taught at one of the gazillion classes I've taken or what 
other techs have experienced and shared with me.

Katherine,
 I have to disagree a bit.  Although the things you mention *could* attribute 
to the cause of a brush yellowing...I will add...I have used CND monomer (I use 
Moxie but it has happened with retention+ also) and powders forever...and I 
love the way it stays on and looks nice. Anyway... IF I use a brush with a 
cover..the bristles tend to yellow...it depends on the brush also.  I use ONLY 
cnd monomer and never use a different monomer...well if I try one..I use a 
different brush..also..I do not use brush cleaner...haven't in a million years! 
 I clean my brush with the monomer...which I also pour fresh each and every 
time.  I lay my brush on it's side to store...so the monomer does not pool into 
the ferrule of the brush.  I don't know why it happens but it does...

Yellowing acrylics happen because;

Contaminated liquid
- leaving liquid in the dapping dish after doing one set of nails, then adding 
more liquid and never cleaning out the dapping dish. 
-Using one of those pump liquid dispensers, liquid left in the lid can go back 
down into the main liquid chamber resulting in the same thing as not cleaning 
out the dapping dish. 
-Brush cleaner in the acrylic liquid. 

Contaminated sculpting brush
-using the same sculpting brush with more than one product. 
-Not cleaning the brush properly.
- Leaving brush cleaner in the brush, i.e. taking the brush out of the brush 
cleaner dabbing it off then dipping right into the liquid with brush cleaner 
still in the brush.

Expired liquid

Liquid that has been left in the sun or extreme heat i.e. the car.

Sometimes it's the top coat that has yellowed not the acrylic.

Some sealant gels made for acrylics will yellow if they are old or have been 
left in extreme heat.

If I can think of anything else I'll post again. Maybe someone else can think 
of 
more reasons for yellow acrylic. The reasons are legion :-)

Yellow gel? My brand is Light Elegance and the ONLY reason for LE to look 
yellow 
is if the nail is lifted. LE gel will not yellow, well I don't know what would 
happen if it was expired or left in the heat. I go through it so fast it can't 
possibly get old and I never leave it in the car. 

I can't speak for other brands, I noticed that the Shellac French yellowed on 
my 
client who went to the beach for vacation.

Thank you so much Kathryn, That helped out a TON!!!  but I have another 
question, why is it that too much liquid can cause yellowing? That is the only 
thing i can think of that is making my nails yellow. I don't smoke, my products 
isn't old, and I've only had them on for about a week.

and surrounding skin are harmful to your nails. People say that acrylics are 
harmful because they went to a NSS salon and had their nails butchered or they 
ripped their acrylic nails off themselves and damaged their own nails, then 
blamed it on the acrylic. Anyone can do the same amount of damage with gels. 
It's not the product, it's how the product is applied and/or removed. FYI 
acrylic is safely removed by soaking in acetone. Picking, ripping or biting 
them 
off causes damaged nails.
