[MIDTERMS] PCOS LAB Flashcards
__________ uses the same cleansing mechanism to get dirt off your skin, but often contains mixture of ingredients meant to help treat common skin conditions.
Body Wash
(T/F): The number of cleansing forms available for use on the body is more limited than for the face, but the range of surfactants used in these products is no less varied.
T
A cleanser used since antiquity, and it remains popular cleanser despite much negative press and the introduction of syndets.
Soap
A method of separating molecules having different densities by spinning them in solution around an axis at high speed.
Centrifugation
A specialized technique used to spin samples at exceptionally high speeds.
Ultracentrifugation
A mild body wash composition. A surfactant component. A structured domain of the mild body wash composition, is measured using graduated cylinder and rotating apparatus.
Lather Volume Test
It is used to determine the percent of structured domain or an opaque structured domain that is present in mild body wash composition that comprises Surfactant component.
Ultracentrifugation Method
Five (5) Components of Surfactants

- Alkyl Polyglucosides
- Polyhydroxy Fatty Acid Amides
Cationic Surfactants
- Benzalkonium
- Benzethonium

(T/F): Shower Gel has firmer, gel-like consistency, while Body Wash is more like liquid soap.
T
__________ is one of the cons of using body wash over bar soap.
Waste
__________ can be an issue whether you choose bar soap or body wash.
Chemical Content
__________ are complex mixtures of chemical agents specially designed to make the external layers of the skin softer are more liable.
Moisturizers / Emollients
__________ can be used to prevent the skin from becoming too dry or oily, such as with light, non-greasy water-base.
Moisturizers
For very dry, cracked skin, __________ are preferable, as they are more lasting than creams and are more effective in preventing water evaporation.
Petrolatum-Based Products
For oily skin, __________ that are specifically non-comedogenic are preferable, as there is less risk of comedo formation.
Water-Based Moisturizers
Appropriate moisturizers to keep aging skin soft and well hydrated are oil-based ones that contain __________ as the base, along with antioxidants or alpha hydroxy acids against wrinkles.
Petrolatum
On sensitive skin (which otherwise is susceptible to skin irritations, redness, itching or rashes), it is preferable to use moisturizers which contain soothing ingredients such as __________, and that minimize potential allergens such as fragrances or dyes, as well as irritants such as acids.
Chamomile or Aloe
It is necessary to blend the water phase and oil phase into an emulsion, but consider the potential effect of the degree of mixing on the product viscosity.
Mixing
(T/F): A high amount of mixing energy, however, can increase the particle size of the dispersed phase and hence affecting the emulsion viscosity.
F / Increase / DECREASE
__________ is generally less of problem in cosmetic processing because the product or phase is usually fluid at elevated temperatures.
Heating
__________ is more commonly the problem with cosmetic emulsion because it generally increases product viscosity. It has more important relationship to final product viscosity because of its effect on crystallite size and dispersion.
Cooling
__________, or the reduction of particles to small and uniform size and their even distribution in medium, is related to shearing in that frequently used to create the particle breakdown.
Homogenization
Eight (8) Components of Mouthwash / Mouth Sprays
- Antibacterial Agents
- Alcohols
- Humectants
- Surfactants
- Flavoring Agents
- Coloring Agents
- Fluorides
- Sweetening Agents
Antibacterial Agents
- Cetyl Pyridinium Chloride - 0.05%
- Chlorhexidine - 0.12%
- Triclosan - 0.03%
- Saline - 0.9%
Present in the range of 10% - 20%. Enhances the flavour, provides sharpness to the taste, aids in masking. Unpleasant taste of active ingredients, functions as the solubilizing agent for some flavoring agents. Acts as the preservative.
Alcohols
5% to 20% of the mouthwash. These agents increases the viscosity of the preparation and enhances the sweetness of the product.
Humectants
They aid in the solubilization of flavors and in the removal of debris by providing foaming action.
Surfactants
It can be carried out against suitable oral microorganisms in suitable liquid media or agar media against control and determining their effectiveness against the growth.
In-Vitro Antiseptic Activity
Done by collecting representative bacterial samples, before and after the use of mouthwash, and culturing and counting colonies on agar plate.
In-Vivo Antiseptic Acivity
Using chemical analysis, surface tension effects.
Deodorizing Effect
