Face pack and masks
1.
2. INTRODUCTION :-
Packs are cosmetics product which have been are since long
ago. Face packs & masks are simple mix of chemicals & natural
ingredients.
colloidal & adsorptive clay & earth which are present
in some packs will absorb grease and dirt from the facial skin. The main
purpose of face packs & masks is to achieve tightening and cleansing
effect. Packs are just not for the face but are used all over the body.
3. NEED OF THE FACE PACKS AND MASKS :-
• The outermost one which is exposed to atmosphere is a horny
layer i.e. stratum corneum & is made up of keratinized dead cell.
• These cells are responsible for maintaining the suppleness of the
skin i.e. maintaining the moisture balance and over all
appearance.
• The cells that have been too long on the surface of the skin are
greyish & dull in tone.
• They may flake & can clog the sebaceous pores
• It may also help to prevent the youthful bloom of the skin.
4. What our skin need is :-
Exfoliation :- This is deep cleansing process helps to unclog the
pores, removes blackheads, whiteheads or dead cells.
Nutrition :- for healthy development & regeneration of new cells
& improvement of skin texture.
This can be achieved by a using suitable face
This rejuvenates to give a smooth blemish free complexion.
5. DIFFERENCE BETWEEN :-
Face packs Face masks
1. These have large amount of solid
particles.
1. The percentage of solid particles is
not more than 5%.
2. It has more prominent cleaning
effect.
2. The cleaning effect of masks are
less as compared to packs.
3.Takes longer time to dry 3. Take less time to dry.
4. The effect of packs is due to
absorbing properties.
4. The effect is a results of the flushing
action produced by masks.
5. They are viscous having paste like
consistency.
5. These are liquid in nature less
viscous & have the consistency of
lotions.
6. It hardens on drying & contract
giving mechanical astringency.
6. They are usually flexible &
impermeable to water even on drying.
6. 7. Removed by cleaning with water or
soaps.
Removed by peeling off.
8. It do not interferes with normal
functioning of skin.
8. It interferes with normal skin
respiration.
9. Constituents are clays or earthy
material.
9. Constituents are gums,
hydrocolloids, rubbers, etc.
7. Purpose :-
1. It is used to draw out the hidden impurities, blackheads and
unclog the pores.
2. Gives immediate toning & revitalization property.
3. Used to induce perspiration.
4. Minimize fine lines & retexturing the skin.
5. Used to skin fresh & make it soft & smooth.
6. It has cleansing effect.
7. Gives youthful glow to skin.
8. Desired properties or characteristics :-
1. Should produced a definite tightening effect after
application.
2. should be free from gritty particles.
3. Must be dermatological non-toxic, non-irritating to normal
skin.
4. It should form adherent coating on the skin.
5. Should posses sufficient absorbent power.
6. Easily & evenly spread on application.
9. Face masks :-
o After application of mask a continuous, elastic &
impermeable film is produced.
o There is rise in temperature, due to retention of heat &
thus, results in increased blood circulation.
o Removal of masks by peeling off produces transient
tightening effect.
o Thus, this effect is of flushing action.
10. Face packs :-
o These are applied in a paste form.
o Water gets evaporated from the skin due to
heat, & eventually hardens & contracts the
skin.
o By giving mechanical astringency effect along
with tightening effect to the skin.
o This is due to absorption by clays.
11. Mechanism of action :-

It can be applied in the form of liquid and
pastes..
If they are in the powder form they are mix
with suitable solvent.
Then applied to the skin in upward and
outward direction.
Allow to dry for 15-20 minutes or as per time
required, but without any facial movement.
Then removed by wet tissue or cloth or by
peeling off.
15. INGREDIENTS :-
1. Powders :- These are used for making face packs & masks are as
follows :-
kaolin or china clay :- It is white to pale cream powders. It has
absorbent property used on oily & acne skin type.
Fuller’s earth :- It is greyish green colored powdered containing
aluminum silicate. It has strongest action than kaolin.
Bentonite :- It is grey-white colored clay containing a minimum
90% hydrated aluminum silicate.
Magnesium silicate :- It is white fluffy powders. It has toning effect
on skin.
Calamine ;- It is pale pink powder containing zinc carbonate &
zinc oxide. It has smoothing effect on the skin.
16. 2. Liquid used for making face packs & masks are as follows ;-
Rose water :- It is a very mild solution. It is used on dry & sensitive skin. It
has smoothing property.
Almond oil :- It has nourishing & soothing effect . Used for mature & dry
skin.
Alcohol :- Ethanol is generally used in packs to decrease the drying time.
It also has an astringent effect.
OTHER INGREDIENTS :-
1. Humectants :- These are used to plasticized the film. Helps to keep skin
moisturized. Glycerin, PG, sorbitol, etc. are used in the range of 2-10%.
2. Film forming agents :-They are used in the range of 10-30%. Film forming
agents are pectin, cmc, cellulose, gelatin, etc.
17. FORMULATION OF FACE MASKS :-
Normal skin :- magnesium carbonate, or kaolin mixed with either rose
water, water or witch hazel.
Dry skin :- oatmeal or calamine mixed with rose water or water.
Oily skin ;- fuller’s earth kaolin mixed with witch hazel extract.
Sensitive skin :- calamine mixed with rose water
Acne skin :- kaolin & fuller’s earth, mixed with hazel extract.
18. CLASSIFICATION OF FACE MASKS
High viscosity or
Paste masks.
Low viscosity or
Liquid masks.
19. 1. High viscosity or paste masks :-
These are generally referred to as clay
packs or mud packs. As they name suggests contains high
of solid dispersed in liquid medium.
Bentonite 15%
Titanium dioxide 2%
Glycerol 4%
Sulfonated
vegetable oil
3%
Water 76%
Preservatives 0.2%
Color & perfume 2-3 drops
20. Uses of ingredients :-
• Bentonite :- gives cleaning effect due to absorption property of it.
• Titanium dioxide :- Increases spreadabilty.
• Glycerol :- As humectant.
• Sulfonated vegetable oil :- Increases cleaning effect & aids in
maintaining the plasticity of product.
2. Low viscosity or liquid masks :-
It is formulated around the film forming
characteristics of one or more hydrophilic colloids. The cleansing
is due to the absorption property. To achieve this a small amount of
clay is added but not more than 5%. This pack is easily removed but
less cleansing effect.
21. Methyl cellulose 10%
Glycerol 7%
Water 83%
Preservatives 0.2%
Color & perfume 2-3 drops
Apart from this, a more simpler & convenient type
of classification is based on the raw material which
is used as a base for any face masks or face packs.
The 5 basic system in which face pack &
masks can be classified are as follows :-
23. 1. Wax based system :-
It consists of paraffin wax or may be the addition of mixture of
waxes. Such as cety & stearyl alcohol.
The use of microcrystalline waxes may assists the continuity of a
suitable wax masks.
These products have the melting point higher than skin
temperature.
Application on skin :-
1. The molten mass is then mixed & molded in a small bowl.
2. Preparation is remelted & brushed on the skin & allow to cool.
3. When the wax get harden, tightness is felt.
4. This form moisture proof barrier, profuse perspiration is induced
that helps to flush dirt & impurities from the follicular opening in
the skin surface.
25. 2. Rubber based system :-
1. The rubber based system is mainly based on rubber latex.
2. It is dispersed in aqueous medium & applied as emulsion on skin.
3.When the water is evaporated the latex form a elastic & water
impermeable film on face.
4. Resulting in rise in temp. & increased blood circulation.
5. Easily removed by pulling off.
6. The skin has become plumped & acquire a rosy or pink hue.
7. To achieve a satisfactory dispersion of latex, high pH is required.
27. 3. Vinyl based system :-
1. This is based on PVA or VAR as film formers.
2. Finished product with PVA can be prepared at pH which can be tolerated
by the skin.
3. PVA is an effective, non-toxic, non-ionic emulsifying agent.
4. The cream or paste type product can be made by addition of kaolin or
bentonite or by use of higher mol.wt., organic thickeners.
5. Various plasticizers may also be incorporated for the flexibility rewet
ability of PVA film.
28. FORMULATION:-
Veegum 0.5%
Kaolin 0.5% Organic thickener
Titanium dioxide 0.3% Good spreading
PVA 12% Film former
PG 8% Humectant, plasticizer
Ethanol 20%
Water 58.7% Vehicle.
29. 4. Hydrocolloids based system :-
1. These can be high viscosity which after application loose water & form
a flexible gel film.
2. The sensation of tightness is produced by the shrinking of gel.
3. Many gums can be used such as, guar gum, acacia, casein, gelatin, etc.
4. The viscosity can be varied with conc. & type of colloid used.
5. They dried out rapidly & have less cleaning effect.
6. Drying time can be increased by adding humectant, but it may cause
precipitation.
7. Cleaning effect can also be increased by adding kaolin & bentonite ,
but not more than 5%.
31. 5. Earth based system :-
1. They are also called as argillaceous masks.
2. They include facial pack & contains high % of solid.
3. As the masks dries on the face it hardens & contract giving the
sensation of mechanical astringency.
4. The presence of absorbent clays such as bentonite, kaolin
produced cleaning effect especially for oily skin.
5. Hydrocolloids such as carrageen gum may be added to stabilize
the suspension of solids.
6. Pharmaceuticals agents like sulphur, astringents, bleaching
agents etc. may be added for some purpose.
33. Anti-wrinkle preparations :-
o The so-called anti-wrinkle preparations which appeared on the market in
the early 1960’s are based on bovine serum albumin, & form an invisible
mask on skin.
o In the manufacturing of bovine albumin, sodium citrate is added to fresh
blood to prevent coagulation, & the blood is centrifuged to remove the
blood cells.
o The anti-coagulation is then neutralized & the serum is defibrinated
spray dried.
o The product is light in color, & completely water soluble.
o Bovine albumin is available from several sources in 3 forms:-
As a 15% sterile soln. containing a suitable preservatives & ready for
immediate use without dilution.
As a 30% soln, to be diluted with an equal volume of water prior to use.
34. And, also in the form of a freeze- dried powder, which before use in
reconstituted with water.
o In fact, a wrinkle smoothing composition disclosed in an American
patent, contains proteins obtained from cow’s milk.
o Namely , α-lactalbumin & some β-lacto globulin.
o Water may be present with the range of 70-90% by weight., together
with 2-4% by wt. of a non-toxic plasticizers such as glycerin or PG.
o The pH should maintained in the range of 5-7.
