What is HEMA?

Today, we want to bring the truth to the nail industry and to all of the Manicure Lovers.

To be precise, what we are going to talk about today is "HEMA Free gel polish"

HEMA is one of those words that if you have heard Hema before, It’s kind of those crazy words that’s taken the industry by storm and people will have a huge reaction to it. And a lot of us don’t even know why we have a huge reaction.

Now let’s talk about what Hema is and why Hema could potentially cause problems

Hema, it’s chemical name is 2-Hydroxyethyl methacrylate

• So is Hema a necessary component in gels?

Actually Hema is added because it gives us really good adhesion of the natural nail.

Natural nails are made of keratin and keratin protein likes that are carboxylic acids and Hema is sort of a long-chain carboxylic acid with a hydroxyl group on one end.

The OH group on the Hema allows it to be more miscible with water so if you have water on you fingernails, so it doesn’t reject the Hema. Hema is also really good as its seen it only has one functional reactive site for the UV cured systems or acrylic systems. So because it only has one of those carbon-carbon double bonds on one end that’s the methacrylate, because it only has one of those it only can enter into one portion of a die functional reaction. So it becomes a chain terminator. If chains could get too long they can become too rigid or they can become too brittle or just not good adhesion.

So, Hema isn’t inherently a bad thing because it creates great adhesion to the natural nail plate, it could bonds with that. But one of the downsides of Hema is that it can get out of control if it’s not bound within the formula properly, or if you get it on your skin, and when you are applying things that contain monomeric Hema you want to make sure that you avoid skin contact. And that’s why as you may have see on pretty much every label for nail care products says “avoid skin contact”

• But there are ways that we can make formulas even safer than having Hema added. 

And so if you see Hema on the ingredient list that’s not necessarily a bad thing, but question might come up what’s the concentration of Hema in a systerm. If the product has 40 percent concentration of Hema in a gel polish system, that increases the chance of becoming allergic to the Hema. There is other molecules that we can use that also have good reactions and good adhesion in a natural nail.Take Hema’s sibling HPMA Hydroxypropyl methacrylate has one additional carbon atom in the backbone and that Hydroxypropyl methacrylate is less allergenic. So some products wind up taking something that has 50％ Hema to 25％Hema and 25％HPMA. And there’s other monomers can be added in there as well.

What’s the best solution?

The answer is “oligomers”. So how it compares to a monomer? 

Oligomer is typically molecule has been built based on the backbone of one of the resins so it’s basically Hema but attached to the Oligomer chain.  And oligomer is ten times the size of Hema monomer. As a result, It’s less likely to enter you bloodstream if it comes in contact with your skin, which makes it safer.

So why companies choose to put so much monomer instead of choosing to put more oligomers in their product?

The answer is very simple. Because Hema is very cheap, so with more Hema, the price will be cheaper. Because it reduces the raw material cost. Oligomers on the other hand are mega expensive. Compared to Hema the oligomers are about 10 times the cost.

As for unna, our brand was born with the goal of being 100% HEMA-free, and we tested the most common gel polishes on the market that claim to be HEMA-free. The result is that almost none of them can do so. 

We are willing to accept the test from the market and we are confident that we will become the new standard in the nail industry. We are looking for partners and agents all over the world. If you want to start your own business, please contact us and we will help you get started.

how to remove gel nail polish safe and quick

Gel manicure are all the rage right now. Everybody loves gel nail polish, but you’re probably removing your gel nail polish the wrong way. So today we are going to learn the right way to do it. And you can do it yourself at home.

The first way to do it , you need to prepare the tools that you need to accomplish this task.

 1: Cotton balls

2: Acetone

3: Nail groomer

4: Aluminum foil

• Step 1: take 1 cotton ball, this is going to remove all of your gel polish from both hands. You can break it up to tiny pieces and what you’re going to make sure you do is you divide them into 10 separate little pieces for each nail. The cotton don’t need to be very thick beacuse you need to dip them into your acetone.

  
  

• Step 2: once it’s completely saturated, put the saturated cotton ball onto the top of your nail bed and you want to make sure that you are not wrapping your entire finger with the cotton ball. This will dry out your cuticles and your nails, which is not good.

  
  

• Step 3: take a small piece of aluminum foil and wrap the nail. This will create a heat conducting type of mechanism and help acetone completely goes through the gel polish. After five minutes, you can check if the gel are peeling. If your gel nails has only been on your nails for about a week, you need to wait little more longer, about ten minutes.

• Step 4: after five to ten minutes, take off the aluminum foil. If you see the gel polish actually peeling up off of your nail,them you are ready for the next step. Take your nail groomer or a wooden stick, and start to push off the gel polish very very gently. Starting at your cuticle and ending at your tip. If you do it backwards and start at the tip, you will risk severely damaging your nail, which completely contradicts the whole purpose of removing your gel polish correctly

  
  

• Step 5：after you remove all of your gel polish, you want to take one more cotton ball, and dip it in some acetone. Then swipe over your nail lightly to get rid of any excess polish that is left over. And finally, you may find your cuticles are a little bit dry. All you need is a bit of cuticle oil and even a moisturizer. Then your nails are good to go.
  

Now you know the right way to remove your gel manicure without sanding down your polish or peeling it off.

And sometimes, if the acetone doesn’t work very well, you need to start your process with buffing the gel polish. The more you can take off with the file the less time you are going to spend on soaking.

Make sure you don’t buff your natural nail, because that will cause serious damage to your nails.

Regarding the tools, you can improvise. You don't necessarily have to use aluminum foil, plastic wrap can work just as well.

If you do not want to spend too much time on this. You may also choose not to use cotton balls. Take some Acetone in a cup and sand the surface of your gel polish slightly. You can then dip five fingers into the acetone. This is very unfriendly to your cuticle and the skin of your fingers, but you can remove the nail polish very easily.

We recommend that you stock up some nail removal packs around the house. It is very convenient. All you need to do is peel off the package, cover the surface of your nails with the cotton side, and stick it on your finger. 5 to 10 minutes later, you can easily remove your nail polish.

The history of unna nail

  1. Beginning

unnanail is a brand of Yiwu Best Nail Biotechnology Co. It was created in 2015. unnanail was born to be a color expert. Its founder, Seven, has over 10 years of experience in the nail industry and wanted to create a brand with full color and all effects.

   2. Turning Point

In the beginning, unnanail focused on product development and soon launched the 900-color series of products. However, a problem arose. 900 colors were a lot, but the simple color classification made it yet more difficult for nail artists to choose.

So, unnanail approached the China Color Association and relaunched the second generation of the unnanail 900 color gel series by asking professional color experts for advice.

   3. Innovation

Now, unnanail's color classification is no longer simply dividing the same color into one category. unnanail has divided them into 9 collections according to different styles. Now, nail artists can choose the right color according to the customer's style or even mood.

Now you can see our beautiful color boards. And our visually striking display shelves.

unnanail is not only committed to color. The second generation of unnanail's color gels is the only product on the market that is truly HEMA-free.Many companies claim that their formulas do not contain HEMA, but after our sampling and testing, all other products contain HEMA. 

In addition to the recipe, unnanail also uses top quality ingredients. For example, color powder.

when creating nail art, it is sometimes necessary to apply each color layer very thinly,

with a thin multi-layer color overlay that brings an exceptionally soft visual beauty.

The thickness of each layer is so thin that it can only be counted in microns after the color layer dries,

which requires the particles of the color powder to be very finely ground. unnanail selects German color powder,

processed by ultra-fine grinding process into nano-level color paste, super fine and smooth.

What kind of builder gel is suitable for your nails?

First, when you have curved nails, and your nail surface is relatively flat Then you only need to use hardener.

Hardener has a medium consistency, so it is suitable for micro-construction

Apply a thin layer without curing it under the light.

Then take the gel and brush it back and forth in the middle of the nail surface until it is flat.

Turn the nail upside down and shape it

Three seconds or so, and then cure it immediately. Compared to the natural nail and the build up nail, it is much fuller

The effect will be more obvious after applying color.

If your nails are thin, soft, flat and uneven.

Use a builder gel to build up your nails.

It has a higher consistency and leveling, and most importantly, it does not generate too much heat when curing.

Take a small amount of gel for the first time

apply thinly without curing

Take a large bead of gel for the second time

Put it on the back edge of the nail

Push it out with light circular motion

Let the gel flow smoothly by itself

Note that the pen should not leave the gel

Thin all around, thick in the middle,  avoid touching the skin

Then turn it upside down and use the pen to paint up and down in the middle

Then you will see the difference.
