Glycyrrhetinic acid

Glycyrrhetinic acid is obtained from the hydrolysis ofglycyrrhizic acid.

Its use has been restricted by short lasting actionwith anti-inflammatory and healing properties.

Structural formula of glycyrrhetinic acid

Hydroxypropyl cellulose (HPC)

HPC (cellulose, 2-hydroxypropyl ether) is a derivative

of cellulose with both water solubility and organic

solubility.


9/26

It can be used as:- an emulsion stabiliser and emulsification agent.

- thickening agent.

- suspending agent.

- stabilizing agent.

- water retention agent.

- rheological behavior agent.

- film forming agents.

Thus can be used in all kinds of cosmetic.

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


11/26

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).


12/26

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.


13/26

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.


14/26

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.

Polyacrylate-1


15/26

MAP

Place of origin

China

Molecular Formula:C6H8O6.x(H3PO4).xMg

Molecular structure:

Magnesium Ascorbyl Phosphate

(MAP)


16/26

Characteristics of MAP

Vitamin C derivative.

Very stable and perfectly

anti-oxygen.

Dispel the free radical of oxygen after enteringthe body - resist wrinkle and anti-ageing.

A kind of water soluble whitening agent.

Powerful antioxidants help to protect skinfrom sun damage.


17/26

Continue

Can catch free oxygen radical to accelerate formationof collagen (the protein that forms the structural gridthat gives skin strength).

Co-function with vitamin E.

High stability in quality and

colour.

Non-poisonous and

non-irritating.


18/26

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.


19/26

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.


20/26

Peony root extract

Root of the peony plant have antioxidant properties.

White peony root Peony root extract


21/26

Butylene Glycol

Structure of 1,3-Butylene Glycol

C4H12O2


22/26

Continue

Ability to stabilize volatile compounds in order tofixing them in cosmetic formulations and retard theloss of aroma.

As antimicrobial agent.

a) Inhibiting effect on the growth microorganisms.

b) Preservation of cosmetics against spoilage by

microorganism.


23/26

Trisodium EDTA

(Trisodium Edetate)

Structure of Ethylenediaminetetraacetic acid (EDTA)

C10H16N2O18


24/26

Continue

Chelating agent

a) To decontaminate radioactive surfaces or in metal

cleaning

b) Helps the action of surfactants

c) Links with other minerals to prevent them from

causing microbial growth.

Preservative in cosmetics.


25/26

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.


26/26

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.
