WHAT IS AN ATTRACTIVE NAIL?
.
The ideal nail polish application procedure includes three layers:
L
1.Base coat:
L
2.Nail polish:
L
3.Top coat:
L
This is the first layer to be applied
L
It
is transparent with a strong adhering capability due to higher resin content.
L
It protects the nail plate from staining.
L
A plethora of colors are available,
L
The expertise of
the nail technician provides various styles of nail
polish application, of which the “French nail
manicure” is very popular.
;
This transparent layer contains more of
nitrocellulose and less resin, so as to protect the
varnish from chipping.

2 kinds:
L
The tough material that holds polish together
L
’s a type
of polymer, meaning it is made of large molecules that string
smaller molecules together.
Ll
Nail polish traditionally requires two
types of resin:
.
film-forming
L
adhesive
,
The film-forming
resin gives the dried polish a …… texture, while the adhesive
polymer adds ….., so the lacquer is less brittle.
L
Nitrocellulose
L
polymer
L
copolymer
L
resin
P
Solvent
L
The solvent makes the polish easy to apply and dry relatively quickly.
L
helps the lacquer spread easily over the nail, and as the polish
dries,
L
, it evaporates to leave behind dry lacquer
L
The key is to make
sure the solvent doesn’t evaporate too quickly (which causes
bubbles), but that it evaporates fast enough to allow nails to dry before
getting smudged.
L
Ethyl acetate
L
butyl acetate
L
propyl acetate,
L
isopropyl
acetate
F
Toulene
,
an inexpensive (and formerly common) solvent but
is used less frequently now due to talk of health and environmental
concerns.
G
Plasticizer
K
Added to keep the resin flexible once it’s dry,
L
what help your manicure last longer.
L
Trimethyl pentanyl di-isobutyrate
L
triphenyl phosphate
L
camphor
0
ethyl tosylamide.
L
Colouring agents
L
Often the main reason a polish is chosen is the color.
,
Multiple
ingredients make up that particular shade.
K
Dyes, for one, are
…., while pigments are not soluble in the solvents used.
L
are often organic materials while pigments are not.
K
CL” followed by numbers on the label;
K
Suspending agents
K
These are additives that help pigments mix with the resin and
solvent, slowing the process of the color settling and separating
in the bottle.
J
Stearalkonium hectorite
U
stearalkonium bentonite.

These prevent polish from changing color or fading when
exposed to sunlight.

MANUFACTURE OF NAIL LACQUERS
L
The manufacture of nail
enamels involves following
distinct processes:
K
Grinding of pigments
I
Manufacture of Nail
lacquers
K
Mixing of pigments with
lacquer
K
Safety aspects
K
Manafture of nail lacquers
D
FILLING
S
Since nail lacquers are highly inflammable, filling, capping and packing must be carried out under fire-proof and explosion- proof condition,
K
Proper care and precautions should be followed, for example, good ventilation, proper electrical wiring and prohibition of cigarette smoking in the working area.
L
PACKING & LABELLING:
L
the most conventional container which
is used for the packaging of nail
lacquers.
H
The applicator consists of an air-tight aluminium canister with an acrylic fiber tip or nib which applies polish directly to nails. مزل يش يا لبق يرتشت يعلا هنل مهم دياو 2

Before nail lacquer is packed , the following tests should be carried out as a measure of quality control :
K
Hardness

These may show some harmful effects e.g.
K
irritation

Cuticle remover
D
…… is the parts of the skin where the skin
adjoin the nails
De
Sometimes it become cornified
D
are used when the removal of
excess cuticle by cutting is unsatisfactory
D
They are in the form of liquid, cream or gel,
based principally on alkaline material such as
potassium hydroxide 1-5% in aqueous or
hydroalcoholic solution
K
helps to counteract the irritation,
J
retard
evaporation and to increase viscosity.
K
Humectants such as glycerin or propylene glycol
K
Other additives such as color, fragrance are
added
K
Cuticle softeners
K
Nail bleach
M
Nail strengtheners or hardeners
K
These are creams, facilitate subsequent removal
of the cuticle
A
Their action is the result of their affinity for protein
H
Composed mainly of quaternary ammonium
compounds
G
Are solutions or creams used for the removal of
ink, tobacco, stains from the nails
J
These are based on aqueous solutions of organic
acids such as citric or tartaric acids in water and
glycerin
H
They are creams containing emollients such as oils,
lanolin
H
To strengthen brittle nail and eliminate dryness,
cracking or splitting
H
To counteract the effect of solvents, present in nail
polish removers and improve the adhesion of nail
lacquer applied subsequently
H
often contain formaldehyde as the
active ingredient.
H
FDA does not object to use of formaldehyde despite its irritation and allergic reaction
provided the product:
U
Contains no more than 5% formaldehyde
J
Provides the user with nail shields which restrict application to the tip (and not the nail bed or fold)
