Designed to remove all kinds of soilage, including sebum, sweat,
environmental dirt, and hair conditioners, as well as to beautify the
hair and make it easy to handle.
Shampoo
Shampoo are _________-based preparations
surfactant
Shampoo cleaning principle
Emulsification
T/F: you need to lower the surface tension between water and sebum, debris and dirt in the hair scalp so that water can easily wash away the dirt in
the hair shaft and scalp.
True
SHAMPOO FORMULATION
Surfactant
Conditioner
Thickener
Water
Preservative
pH buffer
Chelating Agent
Cosmetic Additives
Active Ingredients
-Aids in cleaning and foaming by reducing surface between two
phases.
SURFACTANT
-Also acts as foam booster and foam stabilizers
SURFACTANT
T/F: It is NOT TRUE that the more it ladders, the more foamy it is, the
more effective.
True
lauryl sulfates, sarcosines,
sulfosuccinates
Anionic surfactants
Anionic surfactants for baby shampoo
sulfosuccinates
polyquaternium-10, hydroxypropyl
trimonium chloride
Cationic surfactants
do not foam well and do not remove grease as
efficiently as anionics; less common, more toxic type
Cationic surfactants
common in everyday shampoos for colored hair
Cationic surfactants
cocamidopropyl betaine,
alkylamino acids
Amphoteric surfactants
Non-irritating to the eyes; foam moderately well
Amphoteric surfactants
poloxomers, amine oxides,
polyglucosides
Nonionic surfactants
Usually used as co-surfactant to ionic surfactants
Nonionic surfactants
Usually used as an adjunct to the either cationic or
anionic
Nonionic surfactants
they are used in combination as cosurfactant to
the other surfactants
Nonionic surfactants
T/F: it is not healthy for our hair to condition it everyday or to apply
condition everyday, that’s why it is separated.
True
-Makes the hair soft, shiny, and easier to manage
Conditioner
Quats quaternary ammonium compounds], humectants
(glycerin), silicones (dimethicone), lanolin
Conditioner
-maintain a certain degree of consistency/viscosity to shampoos
THICKENER
-Provides the necessary rheological properties
THICKENER
Sodium chloride, gums, celluloses, polymers
THICKENER
-Prevent growth of microorganisms
PRESERVATIVE
Parabens, urea derivatives, isothiazolones,
benzalkonium chloride
PRESERVATIVE
-Adjust the pH of the formulation
pH BUFFERS
You have to adjust the pH of the preparation to around_______ to _________ (pH of the scalp and hair)
4.5
– 5
Citric acid, glycolic acid
pH Buffer
are used in shampoos to
eliminate that harmful effect to the scalp and hair
Chelating agents
-Also known as sequestering agents
CHELATING AGENTS
Also contributes to the stability of the product
Chelating Agents
EDTA
Chelating Agents
form a complex (chelate) with the multivalent ions present in
water
Chelating Agents
Polyglycol esters, latex opacifiers,
pearlescent color additives
Opacifiers and pearlescent agents
stimulates/enhances hair growth
Aloe vera
helpful in hair health
Tea tree oil –
Usually, these supplementations are for
antioxidant properties
Vitamins (Vitamin B5)
Head and Shoulders
Zinc pyrithione
has a rotten egg odor due to sulfide; usually
masked with scents, for sever dandruff
Selenium sulfide
anti-fungal
Sulfur and salicylic acid
Nizoral shampoo
Ketoconazole
Examples of AI
Zinc pyrithione
Selenium sulfide
Sulfur and salicylic acid
Tar
Ketoconazole
T/F: shampoos are all antifungal in nature, since basically,
dandruff is a fungal infection
