15. Definition
Ideal properties of humectants
Types & examples

16.  Drying of cosmetic may due to:
• Vaporization of water
• Depends o temperature, degree of exposure to air and RH
in the air
16

17.  Hygroscopic material
 Used to reduce the loss of moisture
 Used to keep cream soft: vanishing cream
 Possesses emollient action: vanishing cream
 Forms thin film on skin when applied, influences the texture &
condition of skin, all moisturizing preparation contains
humectants.
 Not only humectants are not responsible to avoid drying of
products but also based on container & closure in which it is
packed.
17

18.  Must absorb moisture from atmosphere
 Should cause a little change only in water content with the
change in RH within normal RH range.
 Compatible with other materials
 Colorless
 Good odor & taste.
 Non-toxic, non-irritant
 Non- corrosive to packaging material
 Not solidify or crystallize at normal condition
 Not be too costly
 Viscosity & temperature curve should be relatively flat.
18

19. Three classes:
• Inorganic
• Metal-organic
• Organic
19

20.  Example: Calcium chloride
 Disadvantages:
• Compatibility problem
• Corrosive nature
 Limited use in cosmetics
20

21.  Example: Sodium lactate
 Advantages:
• Greater hygroscopic power than glycerin
 Disadvantages:
• Compatibility problem, Corrosive nature, Pronounced taste
 Generally used in skin cream as no risk of toxicity
 Admixture of Sodium lactate + lactic acid is used to overcome
pH problems.
 Limited used in cosmetics.
21

22.  Polyhydric alcohols, their esters & ethers
 Widely used in cosmetics
 Most commonly used are:
• Ethylene glycol,
• Propylene glycol,
• Polyethylene glycol
• Glycerol,
• Sorbitol
22

23.  Polyethylene oxide (PEO),
 Polyoxyethylene (POE)
 Available in varying molecular weight
 Based on concentration, effectiveness is depends
 PEG 400 = mol. wt. is 400 Daltons
23

24.  Di-ethylene glycol
 Triethylene glycol
 Di- propylene glycol
 Polyoxyethylene glycerin
 Xylitol
 Mannitol
• Sorbiton
• Polyoxyethylene sorbitol
• Glucose
• Triethanolamine
