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.

The ingredients of ordinary nail gel generally consist of two categories, one is composed of solid ingredients, mainly pigments, glossy substances, etc.; the other consists of liquid solvent components, mainly acetone, ethyl acetate phthalate, formaldehyde.

What are the other uses of nail gel?

There are some loose screws, how did you deal with it here? Just remove the square screws, next, apply a coat of clear nail gel to the ends of the screws and quickly screw them into the grooves, the polish will act as an interior trim to glue them together. Aside from bonding, another cool use is polish on outdoor furniture, which prevents rust, prevents rain from scouring, and keeps those screws looking new and good. If there is a torn or punctured window screen, there is no need to replace it, because repairing it is very simple, just apply clear nail gel on the front and back of the torn screen and blow dry it with a hair dryer. Maybe the repair wasn't perfect.

How to choose color nail gel?

Given a whole shelf of nail gel, aside from the color, where do you choose?

Here are some highlights for your reference:

1.When buying, remove the nail gel brush to see if it drips smoothly over the brush in the form of water drops. If the flow is very slow, this means that the nail gel bottle is too thick and not easy to wipe evenly.

2.When the brush is removed, press the bottle opening left and right to test the elasticity of the bristles.

3. Try to choose nail gel with thin bristles that are easier to apply (compare the bristles of different nail gel brands).

4.When the brush is filled with nail gel and removed, the brush still retains a slender shape at the end, indicating that the brush is good and some become very thick.

5. Look at the production date.

How to remove nail gel?

1. Use nail gel remover to remove

Volatile organic solvents in nail gel remover can help dissolve and remove nail gel.

2. Use cleaning oil to remove

To remove the finished nails, we can use cleaning oil. First, apply a thin layer of makeup remover to your lacquered nails, then wait about 3 to 5 minutes before slowly rubbing with something hard. Finally, gently wipe with a cotton pad and wipe off. Rinse your hands with water.

3. Use hairspray to remove

Hairspray and nail gel contain the same chemical ingredients. Do not leave the hairspray on too long, otherwise it will dry out on the nails. It hurts the nails and leaves unsightly marks.

4. Use toothpaste to remove

All you need is a dab of toothpaste and then an old toothbrush or paper towel to wipe off the nail gel. In general, white toothpaste is best for removing nail gel.

What is the method of applying nail polish to prevent "warping"?

When applying, leave a little space (0.5-1 mm) on both sides of the nails. The nail polish applied to the skin must be scraped off, and then sealed with top coat, so that the edges are not easy to warp.

In case the tip is warped, it is not very serious, you can press it back and add a layer of top coat to seal it.

How to apply gel polish that's not easy to fall off?

The nail polish is simple and easy to apply, but it starts to fade after a few days on the fingers. The fading of nail polish is a very troublesome problem for us, so can this problem be avoided when applying gel polish? The answer is YES, as long as girls pay attention to the way of applying gel polish, you can color your nails. Keep it up for a long time!

The factors that affect nail fading are the texture of the nail polish, the method of applying the nail polish, and the follow-up maintenance after the manicure.

First of all, we should choose nail polish with less formaldehyde content. The higher the formaldehyde content, the faster the nail polish will dry and fall off, so be careful when choosing.

Second, pay attention to how you apply it. When applying gel polish, you must remember the principle of secondary coloring, that is, after applying the thinner first layer, you should apply a thicker second layer.

Again, after the manicure, maintenance work should be done well. After finishing the manicure, we can apply a layer of nail protection oil on the nails to make the color of the nails more glossy and durable.
