Water (or Aqua)
Structural formula: HO
Water is the number one ingredient used in cosmetic
formulations.
Water must be prepared by going through filtering,
distilling, deionizing, and sterilizing before it is usedin cosmetics.
Water is both a vehicle and an active agent.
Had four functions: Solvent, transportant, lubricant and
coolant

Benzoic Acid (C7H6O2)
Structural formula:
Physical form: Solid
Molecular weight: 122.13 g/mol
Benzoic acid is a natural ingredient occurring in many
foodstuffs and in plant extracts.
Benzoic acid, its salts and esters are used as preservatives in
cosmetic products, with a maximum concentration of 0.5 %,
(calculated as acid).

Calcium Chloride
Structural formula: CaCl
It is used in cosmetics as an emulsifier and texturizer.
Alcohol
When the word alcohol is used alone, it refers to ethanol.
Alcohol is used as a fast drying solvent & also preservatives.
When used in products not licensed for drinking, ethanol
is usually denatured.

Fragrance
Fragrance formulas are considered trade secrets,
manufacturers only state fragrance on the label and
do not need to identify the chemical makeup.
Any natural or synthetic substance or substances used
solely to give an odor to a cosmetic product.

Cationic compatibility.
Excellent clarity in low pH
applications (pH < 6.0).
Synergistic with surfactants and salt in thickeningmechanism- cleansing applications.
Suspension of beads, capsules and powders.
Treats blemishes and helps prevent breakouts
without irritating skin.

Phosphate
The phosphate use in cosmetics:Mono- and Di- sodium phosphates
Functions : Buffers
Salicyclic acid Has multifunctional properties to help with a variety
of skin problems, including acne, pimples and
blemishes. Is the key additive in many skin-care products for the
treatment of acne.

It is used in cosmetics as an exfoliant, and is the only
source of beta hydroxy acid (BHA).
BHA also has the ability to penetrate into the pore
(AHAs do not), and can exfoliate inside the pore as
well; it is thus considered effective for reducing
clogged pores and breakouts.
It treats acne by causing skin cells to slough off morereadily, preventing pores from clogging up.

Conclusion
Although this product is useful to reduce blemish
on our face, but what are the sides effect that this
product will produce either to human or to
environment?
And what are precautionary steps should take
when using this product?
Example of sides effect:
a) EDTA i) Attempts to scavenge the tracemetals used and required by body.
ii)Potent eye irritants.

Continueb) Hydroxypropyl cellulose - is quite soluble, and
can be fermented in the large intestine. Large
concentrations can cause intestinal problems,such as bloating, constipation and diarrhea.
Example of precautionary steps:
a) Check with your doctor If you have skin allergiessuch as calcium chloride is an irritant, particularlyon moist skin.
