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.
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.

How to remove 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.
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.
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.

Five nail removal tutorials that don't hurt your nails
Doing manicure is fashionable and beautiful, yet it is easy to apply it, but hard to remove it. If you are not careful, your nails will be thinned and become miserable. Next, we will explain how to remove nail polish, nail gel, Acrylic fake nail, builder gel, and acrylic powder nail.
Nail polish is made from a mixture of volatile chemical solvents and colorants, so it can be quickly broken down with alcohol, which are also solvents. You only need to use the alcohol nail removal pack to gently press and rub to quickly remove it. This is currently the quickest and simplest way to remove nail polish.
Nail polish is mainly a mixture of resin, photoinitiator and color powder. After being exposed to a specific UV light, it will harden quickly. The nail gel material will become strong after curing and will not dissolve easily with the solvent. The best way to remove the nail gel is to sand the surface of the top coat to reduce its thickness, then wrap the nail with a nail remover pack for 3 to 5 minutes and remove it. Just gently push and scrape with a steel pusher. If there is still a small amount of gel left, sand it down with a sanding strip.
Fake nails are thicker and harder than nail gel applied with a single color. Even if you use a nail removal kit directly, it will be very slow and hard. The best way is to use nail clippers to cut it short, then use a polisher to polish off a thin layer of the fake nail, then use a nail removal pack to soften the nail for 5 to 10 minutes. After the time is up, use a steel pusher to remove the residue. Remember, if there is still a large area of un-softened gel residue, do not use tools to push, you should continue to wrap it with the nail removal pack and wait for a period of time to remove it again.
Builder gel nail is the hardest and most difficult type of nail product to remove. If you use the incorrect method or forcefully peel it off, you will cause very serious damage to your own nails and a large area of damage overall. The correct way is to cut it short with a nail clipper first and use a sander to thin the gel as well. (Note: If you still need to do the extensions, you don't need to remove all the gel, just cover it and recreate it.) If you don't want to recreate it, just wrap it with a nail removal pack for 5 to 10 minutes and then use a steel pusher to remove it.
Due to the different material of Acrylic powder, the speed of fusion with nail removal pack is faster than builder gel. After you cut it short and polish it, you can remove it after 3 to 5 minutes by wrapping it with a nail removal pack. If there is any residue left after a light push with a steel pusher, just use a sponge to polish it untill it' s clean.
Why Gel Nail Polish is better than Regular Nail Polish？
Regular nail polish is always tried and true.
This is a necessity for middle school students to spend the night away, and a staple for the working woman’s outfit planning.
But what about gel nails? What can gel manicure give you that regular nail polish can't give you?
Gel manicure has still quickly become the main product of salons.
Nevertheless, for those who are not sure whether to try new gel polishes, we have collected their benefits for you:
Gel nail polish is thicker than regular nail polish.
The main feature that distinguishes it from classic manicure is part of the curing application process
because gel nail polish does not dry naturally.
Curing refers to putting the nails under LED or ultraviolet light to activate the chemical process to dry each layer of nail polish.
Considering that the gel nail application has extra time to repair the nail polish,
you can immediately leave your appointment or home application to completely dry the nail.
Quick-drying, durable formula, gel polish is hardly broken.
Your gel manicure is very resistant to peeling or stains, and the color will be as bright and shiny as the first day.
Gel polish can be used for at least 2-3 weeks, while regular nail polish will not fall off for a week.
In the case of light application, your gel nails last at least twice as long as normal nail polishes,
but in fact, they can make your nails four to six times the standard.
Take the core ingredient color powder as an example:
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. unna selects German color powder,
processed by ultra-fine grinding process into nano-level color paste, super fine and smooth.
The base coat of colored Nail polishes must usually be colorless, i.e. transparent, so that the colored Nail polish on the back can bring out the color better. There are also some base oils with some color, such as light pink and light blue. In fact, this type of Nail polish is almost invisible when applied to the nails, but it is also possible, but do not use the type of Nail polish that is visible when applied, as this will affect the color saturation of the later applied Nail polish.
What should I pay attention to before applying colored Nail polish?
What is the composition of Nail polish?
What colors do the Nail polishes have?
It is best to apply the Nail polish as little as possible to the whole nail, otherwise it will become slightly uneven and affect the shine of the nail.
2.With each application, the amount of Nail polish on the brush should be as equal as possible to make it easier to apply evenly.
3. Be sure to wash the grease off your hands before applying.
The basic components of Nail polish are nitrocellulose, alcohol phenolic resin, ethyl acetate, camphor, ethanol, toluene, dyes, etc. Softeners for Nail polish are dibutyl phthalate, tri-o-tolyl phosphate, etc. Softeners prevent the Nail polish from creasing and twisting when drying Nail polish solvents make 3/4 of the finished product volume out of acetone, ethyl, butyl, pentyl acid salts and various alcohols.
Nail polish is a cosmetic used to modify and increase the beauty of nails. It can form a friction-resistant film on the surface of the nails to protect and beautify the nails. The colorants of Nail polish mainly include inorganic pigments, organic pigments, pearlescent pigments and metallic glitter colorants. Inorganic pigments are opaque; organic pigments are very brightly colored substances that give nails a vibrant color. According to the different properties of its pigments, the color of Nail polish can generally be divided into the following colors:
Red Nail polish: mainly including wine red, pink and other colors;
Green Nail polish: mainly includes dark green, bright green and other colors;
Silver Nail polish: mainly including silver gray and other colors;
Black Nail polish: mainly includes light black, dark black and other colors;

What are the basic ingredients of colored nail gel?
The color of the base coat is transparent or creamy white, and the base coat is applied after the nail is polished. The base coat is selected according to the texture of the customer's nails. If the nails are soft, calcium oil can be added. If the nail gel is needed, the base coat can prevent the nails from turning yellow and play a nutritional role. Note that primer must be applied before nail gel is applied in manicure.
The main method of cuticle oil is to do basic cleaning work first, apply softener to the nail skin at the edge of the nail, wait for 1 to 3 minutes, after the nail skin softens, use a dead skin pusher to push bacl the dead skin, and then use a dead skin scissors to cut off dead skin.
The nail gel is a kind of resin gel; nail gel is general nail gel, different from nail polish, phototherapy gel is thicker than nail gel, both must be irradiated through phototherapy lamp, Unlike phototherapy gel, which can be used to extend nails directly, nail gel glue is not recommended for nail extensions because it is relatively thin. It is only suitable for rubbing the nail surface, or to do nail extensions through nail stickers.
The basic components of nail gel are nitrocellulose, alcohol phenol resin, ethyl acetate, camphor, ethanol, toluene, colorants, etc. Plasticizers for nail gel include dibutyl phthalate, tri-o-tolyl phosphate, etc. Plasticizers prevent the nail gel from wrinkling and twisting when it dries. nail gel solvent accounts for 3/4 of the finished product volume. Commonly used solvents are acetone, ethyl, butyl, pentyl acid salts and various alcohols. The pigments in nail gel are insoluble. Soluble pigments tend to stain the skin around the nails and are difficult to wash off. The pearlescent agent contained in nail gel makes the product bright and dazzling. Natural pearlescent agents are often taken from fish scales, and synthetic pearlescent agents include metal salts such as barium oxychloride.

You can use top coat on ordinary nail polish, Before doing this you must polish the surface of the nail, the human real nail surface is smooth, and greasy, must use sanding hair, or nail polish may not stick firmly, and easy to fall off.
Detailed operation steps are:
After grinding the nail surface, dusting with a dusting brush, and then use a cotton pad with a certain amount of cleaning liquid to clean the nail surface. It is also important to note that if you do the hand care first and then cure it, if you do not apply sunscreen, it is more likely to lead to skin aging.
nail polish is easy to cracking after curing it. The step of applying a layer of top coat is specifically for gel polish, which is difficult to dry in natural conditions, while ordinary nail polish can dry in natural conditions easily. The difference between gel polish and regular nail polish is that gel polish lasts longer and can make more beautiful shapes, and by saving the time to dry by curing, gel polish occupies the majority of the nail art market. It would be a better choice.
The steps to use gel polish for manicure are as follows.
1. First trim the nails, clean the dead skin around the nails, and then use a nail file to polish off the grease layer on the surface of the nails, so that the base gel and nails fit more closely. You can use primer as well.
2. Use the base coat, cure it, then use the color gel, every time you apply it, cure it once, after two times if you think the color is suitable, then you can carry out the top coat, if you think the color effect is not good, you can apply the third time.
3.Choose the type of top coat according to your preference and needs. After applying the top coat, cure it and let the it dry thoroughly so that all the steps are finished. Usually gel polish needs to be removed after 2~3 weeks. When removing, first grind off the top coat and then use nail remover to handle it, avoid picking nails by yourself.
The answers is: No! Clear nail polish can't be used as top coat. Transparent nail polish does not have the ability to fix gel polish and is not as strong as gel polish, gel polish has a strong adhesion after use on the nail, and transparent nail polish generally only has a shelf life of four or five days, so it is not suitable for use as top coat.
The point of top coat is to hold the gel polish in place so that it doesn't layer on the nail and crack easily, but obviously clear nail polish doesn't have that ability. The ingredients contained in the top coat are usually chemical based, so it is very strong, but after applying the top coat you need to cure it.
If it is ordinary clear nail polish in the process of curing, it’s very easy to crack. Clear nail polish can't be used as top coat, these two are not the same kind of product.
