Cleanser Flashcards
T/F: Cleansers may solubilize lipids and extract skin components
True
T/F: Cleansers do not damage skin proteins
False; Cleansers damage skin proteins owing to charge density of surfactant aggregates
A lot of cleansing products utilize ________ surfactants
which are generally known to possess alkaline pH
anionic
T/F: Alkaline pH can irritate skin
True; this is due to pH alteration (Skin is acidic)
Cleansers have the potential to cause irritation, itching, ____________, and ___________
inflammation; allergies
T/F: The use of hand sanitizers is as effective as hand washing in infection control.
False
This type of cleansers have amphiphilic molecules, anionic surfactants, alkaline pH of 9.5-10
Soaps
T/F: Skin Cleansers may be oil based
True; skin cleasers can be oil or alcohol based
Synthetic Surfactants are _________ anionics and have a pH of ________
milder; 7
commonly used anionic surfactant
Acyl isethionate
Chemical cleaning is achived through _________ and _________ the dirt
emulsifying; dissolving
The mechanism is usually via emulsification. It is able to mix with the oil as well as water.
Surfactants
The principle is dissolution. Whatever substances can be dissolved in that particular solvent, that is the part that can be removed.
Solvent
Types of chemical cleansers
Surfactants, solvents
Cleansing principle based on abrasion or friction
Physical cleaning
_________ (type of cleanser according to foamility) cleansers are the most common and popular type
Foaming Cleanser
Gives the most refreshing sensation
Foaming Cleanser
Has Surfactant solutions, gels, scrubs, and O/W emulsions with high cleansing power
Foaming Cleanser
Milder to the skin (do not contain anionic surfactants)
Low-foaming Cleansers
T/F: Low-foaming cleansers may contain foam booster
True
Solvent-based or emulsion-based
Non-foaming Cleansers
Facial Cleanser Formulation
Surfactants, Solvents, Thickeners, Skin Conditioning Agents, pH buffers, Abrasives, Colorants, Fragrances, Preservatives, Antibacterial agents, Absorbents, Astringents
Sodium Lauryl
Sulfate (SLS), Sarcosinates, Isethionates, Sulfosuccinates,andmonoalkylphosphates
Anionic surfactants
Amines, Quaternary ammonium compounds
Cationic surfactants
These surfactants are mainly used as conditioners more than cleansers
Cationic surfactants
betaines
Amphotheric surfactants
foam very well. But their cleansing action is not as good as anionics
Amphotheric surfactants
Fatty alcohols
and Amides. Generally they do not foam
Nonionic surfactants
Mild surfactants that can be used in baby care
products
Amphotheric surfactants
