Q

__________ can be an issue whether you choose bar soap or body wash.

A

Chemical Content

17
Q

__________ are complex mixtures of chemical agents specially designed to make the external layers of the skin softer are more liable.

A

Moisturizers / Emollients

18
Q

__________ can be used to prevent the skin from becoming too dry or oily, such as with light, non-greasy water-base.

A

Moisturizers

19
Q

For very dry, cracked skin, __________ are preferable, as they are more lasting than creams and are more effective in preventing water evaporation.

A

Petrolatum-Based Products

20
Q

For oily skin, __________ that are specifically non-comedogenic are preferable, as there is less risk of comedo formation.

A

Water-Based Moisturizers

21
Q

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.

A

Petrolatum

22
Q

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.

A

Chamomile or Aloe

23
Q

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.

A

Mixing

24
Q

(T/F): A high amount of mixing energy, however, can increase the particle size of the dispersed phase and hence affecting the emulsion viscosity.

A

F / Increase / DECREASE

25
Q

__________ is generally less of problem in cosmetic processing because the product or phase is usually fluid at elevated temperatures.

A

Heating

26
Q

__________ 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.

A

Cooling

27
Q

__________, 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.

A

Homogenization

28
Q

Eight (8) Components of Mouthwash / Mouth Sprays

A
  1. Antibacterial Agents
  2. Alcohols
  3. Humectants
  4. Surfactants
  5. Flavoring Agents
  6. Coloring Agents
  7. Fluorides
  8. Sweetening Agents
29
Q

Antibacterial Agents

A
  1. Cetyl Pyridinium Chloride - 0.05%
  2. Chlorhexidine - 0.12%
  3. Triclosan - 0.03%
  4. Saline - 0.9%
30
Q

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.

A

Alcohols

31
Q

5% to 20% of the mouthwash. These agents increases the viscosity of the preparation and enhances the sweetness of the product.

A

Humectants

32
Q

They aid in the solubilization of flavors and in the removal of debris by providing foaming action.

A

Surfactants

33
Q

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.

A

In-Vitro Antiseptic Activity

34
Q

Done by collecting representative bacterial samples, before and after the use of mouthwash, and culturing and counting colonies on agar plate.

A

In-Vivo Antiseptic Acivity

35
Q

Using chemical analysis, surface tension effects.

A

Deodorizing Effect
