Types of Cosmetic Product and Their Preparation (Hair Products) Flashcards
(101 cards)
______ is a term used to describe the study of hair and its diseases and care.
Trichology
_______ is the general term for the action taken to help maintain personal hair hygiene.
Hair care
_______ is a staple hair care product that cleanses the hair and scalp.
Shampoo
It is composed of multiple layers of keratinized, flattened cells (scales), which overlap in a roof-tile formation with an intercellular cement to bind them together. Composed primarily of keratin.
Cuticle
Major component of the hair shaft. It contributes to the mechanical properties of the hair fiber, including strength, elasticity and curliness. Presence of melanin in the cortex that gives hair color
Cortex
referred to the core. Viewed as a framework of keratin
Medulla
are 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
Shampoos are surfactant-based preparations. Therefore, their
cleaning principle is _____.
emulsification
Insoluble particulate soil can be removed by _______ assisted by
repulsion between the surfactant molecules adsorbed onto
the hair fiber and those dissolved in the soil
electrostatic
repulsion between the soil and the hair fiber
• Highly effective cleansers & foamers
• Often the main ingredient in shampoo
• Can be irritating depending on the type
Anionic Surfactants (Main Cleansing Agents)
Types of Anionic Surfactants
Alkyl Sulfates (e.g., Sodium Lauryl Sulfate - SLS)
Alkyl Ether Sulfates (e.g., Sodium Laureth Sulfate - SLES)
Alkyl Polyethylene Glycol Sulfates (APES)
Sulfosuccinates
→ Strong cleansers, more irritating
Alkyl Sulfates (e.g., Sodium Lauryl Sulfate - SLS)
→ Gentler than SLS, more mild and foamy
Alkyl Ether Sulfates (e.g., Sodium Laureth Sulfate - SLES)
→ Soluble in water & oil, milder than SLS; for formulations where milder surfactant is desired
Alkyl Polyethylene Glycol Sulfates (APES)
→ Very mild, often used in baby shampoos
→ Monoesters preferred over diesters for better foam & less irritation
Sulfosuccinates
• No charge – gentle and versatile
• Added for foam boosting, thickening, conditioning
Non-Ionic Surfactants (Supporting Agents)
• Lauramide DEA, Cocamide MEA/DEA
• Functions: Foam boosters, thickeners, conditioners
Alkanolamides
• Co-surfactants with anti-static, mild conditioning effects and foam boosting
Amine Oxides
• Change charge based on pH (acidic = positive, basic = negative)
• Common in baby shampoosfor their mildness & low eye
irritation
Amphoteric Surfactants (Mild Co-surfactants)
Gentle cleansing, used in sensitive formulations
Lauroamphoacetate
Reduces irritation, boosts foam
Cocamidopropyl Betaine
• Positively charged
• Not used for cleansing – hard to rinse, can attract dirt/oil
• Main use: Hair conditioners (for static reduction, smoothness)
Cationic Surfactants (Conditioners, Not Cleansers)
Typical Ratio:
10 parts anionic surfactant : 1 part foam booster
e.g., 40% SLES + 4% cocamidopropyl betaine
