Questions and Answers
  • 1. 

    Which of the following is inorganic type of humectant?

    • A.

      Calcium chloride

    • B.

      Sodium Lactate 

    • C.

      Glycerol

    • D.

      Ethylene glycol

    Correct Answer
    A. Calcium chloride
    Explanation
    Calcium chloride is an inorganic type of humectant because it is a salt compound that does not contain carbon-hydrogen bonds. Inorganic humectants are commonly used in various industries, including food and cosmetics, to attract and retain moisture, preventing products from drying out. Calcium chloride is particularly effective as a humectant due to its hygroscopic properties, which allow it to absorb and hold onto water molecules. This makes it a suitable choice for applications where moisture retention is crucial, such as in food preservation or as a drying agent in industrial processes.

      Fungi 

    Correct Answer
    B. Psudomonas 
    Explanation
    Pseudomonas is a type of microorganism that is commonly found in unused cosmetic products. It is known to thrive in moist environments and can contaminate products that have not been properly stored or have expired. Pseudomonas can cause infections and skin irritations if it comes into contact with the skin, making it important to ensure the cleanliness and safety of cosmetic products before use.

  • 3. 

    Which of the following agents are used to prevent spoilage in cosmetic products

    • A.

      Colors

    • B.

      Fragrance

    • C.

      Preservatives

    • D.

      Humectants 

    Correct Answer
    C. Preservatives
    Explanation
    Preservatives are used in cosmetic products to prevent spoilage. They help to inhibit the growth of microorganisms such as bacteria, fungi, and yeast, which can cause the product to deteriorate or become contaminated. Preservatives play a crucial role in extending the shelf life of cosmetic products and ensuring their safety for use. Colors, fragrance, and humectants do not have the same antimicrobial properties as preservatives and are not primarily used to prevent spoilage.

    Rate this question:

  • 4. 

    What is/are the reasons of dryness in cosmetic products?

    • A.

      Vaporization of water

    • B.

      Degree of exposure to air

    • C.

      Relative humidity in air

    • D.

      All the above

    Correct Answer
    D. All the above
    Explanation
    Dryness in cosmetic products can occur due to multiple reasons. One reason is the vaporization of water, where the moisture in the product evaporates over time, leaving it dry. Another reason is the degree of exposure to air, as prolonged exposure can cause the product to lose moisture and become dry. Additionally, the relative humidity in the air can also contribute to dryness, as low humidity levels can lead to moisture loss from the product. Therefore, all of the given options can be reasons for dryness in cosmetic products.

    Rate this question:

  • 5. 

    I am an o/w type of emulsion but after application on skin, sufficient water evaporates and permits a phase inversion to w/o type, who am I? 

    • A.

      Cold cream

    • B.

      Vanishing cream

    • C.

      Cleansing cream

    • D.

      Moisturizing cream

    Correct Answer
    A. Cold cream
    Explanation
    Cold cream is a type of emulsion that starts as an oil-in-water (o/w) emulsion. However, when applied to the skin, the water in the cream evaporates, causing a phase inversion and transforming it into a water-in-oil (w/o) emulsion. This allows the cream to form a protective layer on the skin, helping to retain moisture and prevent dryness.

    Rate this question:

  • 6. 

    Ideal sunscreen should absorb light preferentially over the range of 

    • A.

      240-280 mµ

    • B.

      280 - 320 mµ

    • C.

      320-360 mµ

    • D.

      360-400 mµ

    Correct Answer
    B. 280 - 320 mµ
    Explanation
    The ideal sunscreen should absorb light preferentially over the range of 280-320 mµ. This range corresponds to the ultraviolet (UV)B wavelength, which is known to be harmful to the skin. By absorbing this range of light, the sunscreen can protect the skin from the damaging effects of UVB radiation, such as sunburn and increased risk of skin cancer.

    Rate this question:

  • 7. 

    Which of the following is NOT used as an evaluation of sunscreen?

    • A.

      Erythemal damage

    • B.

      Sun-screen index

    • C.

      Rancidity 

    • D.

      In-vivo skin testing

    Correct Answer
    C. Rancidity 
    Explanation
    Rancidity is not used as an evaluation of sunscreen because it refers to the deterioration of fats and oils, typically caused by oxidation. It is not a relevant factor in assessing the effectiveness or safety of sunscreen products. Evaluation of sunscreen typically involves assessing factors such as erythemal damage (skin redness caused by sunburn), the sun-screen index (a measure of the product's ability to protect against UV radiation), and in-vivo skin testing (testing on human subjects to evaluate the product's performance on the skin).

    Rate this question:

  • 8. 

    Titanium dioxide is commonly present in

    • A.

      Vanishing cream

    • B.

      Sunscreen cream

    • C.

      Aqueous calamine cream

    • D.

      Ophthalmic cream

    Correct Answer
    B. Sunscreen cream
    Explanation
    Titanium dioxide is commonly present in sunscreen cream because it is an effective UV filter. It helps to protect the skin from harmful UV rays by reflecting and scattering them. Titanium dioxide is a mineral that is able to block both UVA and UVB rays, making it a popular ingredient in sunscreens. It is also known for its non-irritating and non-allergenic properties, making it suitable for use in skincare products. Therefore, it is logical for titanium dioxide to be present in sunscreen cream to provide optimal sun protection.

    Rate this question:

  • 9. 

    Which of the following may attract the sun's UV rays to your lips?

    • A.

      Lip Balm

    • B.

      Lip Liner 

    • C.

      High-gloss sheer lipstick

    • D.

      Opaque cream lipstick

    Correct Answer
    C. High-gloss sheer lipstick
    Explanation
    High-gloss sheer lipstick may attract the sun's UV rays to your lips because the glossy finish reflects light, including UV rays, back onto the lips. This can increase the exposure of the lips to UV radiation, which can be harmful and potentially lead to sunburn or long-term damage such as premature aging or skin cancer.

    Rate this question:

  • 10. 

    According to some experts, which product should you replace every three months?

    • A.

      Powder eye shadow 

    • B.

      Mascara

    • C.

      Lipstick

    • D.

      Powder

    Correct Answer
    B. Mascara
    Explanation
    Mascara should be replaced every three months because it can easily become a breeding ground for bacteria. The product comes into contact with the eyes and the wand is repeatedly inserted into the tube, which can introduce bacteria. Using old mascara can lead to eye infections and irritations. Therefore, it is recommended to replace mascara every three months to maintain eye health and hygiene.

    Rate this question:

  • 11. 

    Which of the following promotes bacterial growth in makeup?

    • A.

      Sharing makeup with friends

    • B.

      Exposing makeup to light and heat

    • C.

      Using makeup when you have eye infection

    • D.

      All the above 

    Correct Answer
    D. All the above 
    Explanation
    Sharing makeup with friends can promote bacterial growth because it can transfer bacteria from one person to another. Exposing makeup to light and heat can also promote bacterial growth as bacteria thrive in warm and humid environments. Using makeup when you have an eye infection can introduce bacteria into the product, which can then multiply and contaminate the makeup. Therefore, all of the given options can promote bacterial growth in makeup.

  • 12. 

    Which of the following is the most common injury from cosmetics?

    • A.

      Allergic reaction to foundation

    • B.

      Damaged fingernail with acrylic tips

    • C.

      Scratching the eye with mascara wand

    • D.

      All the above 

    Correct Answer
    C. Scratching the eye with mascara wand
    Explanation
    Scratching the eye with a mascara wand is the most common injury from cosmetics. This can occur when applying mascara, especially if the wand is used improperly or if the person is in a hurry. The bristles of the wand can scratch the delicate surface of the eye, leading to discomfort, redness, and potential damage. Allergic reactions to foundation and damaged fingernails with acrylic tips are also possible injuries from cosmetics, but they are not as common as eye injuries from mascara wands.

    Which of the following preparation is curative? 

    • A.

      Antiperspirant 

    • B.

      Lipstick

    • C.

      Nail Polish

    • D.

      Eye mascara

    Correct Answer
    A. Antiperspirant 
    Explanation
    Antiperspirant is the correct answer because it is a preparation that helps reduce or prevent sweating, typically used on the underarms. It contains ingredients that block the sweat glands and temporarily stop sweating. This curative effect helps control excessive sweating and keeps the user dry. On the other hand, lipstick, nail polish, and eye mascara are cosmetic products used for enhancing beauty and do not have any curative properties.

    Mouthwash is used for refreshing the mouth, as it helps to eliminate bad breath and leave a fresh feeling. It also acts as a deodorant, as it helps to mask any unpleasant odors in the mouth. Additionally, mouthwash has antiseptic properties, which means it can help to kill bacteria and prevent infections in the mouth. Therefore, all of the given options - refreshing, deodorant, and antiseptic - are correct uses of mouthwash.

      True

    • B.

      False

    Correct Answer

  • 17. 

    Using mascara, the wrong way can cause eye injuries and infections, even blindness.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Using mascara incorrectly can indeed lead to eye injuries and infections, and in severe cases, it can even cause blindness. When mascara is applied incorrectly, it can introduce bacteria into the eye, leading to infections such as conjunctivitis. Additionally, if the mascara wand accidentally pokes or scratches the eye, it can cause corneal abrasions or other injuries that can impair vision or lead to blindness. Therefore, it is important to follow proper hygiene practices and application techniques when using mascara to minimize the risk of these complications.

  • 18. 

    If a product is labelled "all natural" or "organic," it's probably not going to irritate your skin.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement suggests that if a product is labeled "all natural" or "organic," it is unlikely to irritate the skin. However, this is not necessarily true. Just because a product is labeled as such does not guarantee that it will not cause irritation. Natural or organic ingredients can still cause allergic reactions or irritation in some individuals. It is important to read the ingredients list and consider individual sensitivities before assuming that a product will not irritate the skin.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    There is no scientific evidence or general rule that states women with wrinkles shouldn't use powder. The use of powder is a personal preference and can be beneficial for reducing shine and setting makeup. It can help to create a smooth and matte appearance on the skin, which can be especially useful for individuals with oily skin or for those who want to minimize the appearance of pores. Therefore, the statement that women with wrinkles shouldn't use powder is false.

    Dark lipstick makes thin lips look fuller.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Dark lipstick can actually make thin lips appear even thinner. Lighter shades of lipstick tend to create the illusion of fuller lips, while dark shades can make them appear smaller and more defined. Therefore, the statement that dark lipstick makes thin lips look fuller is false.

    Rate this question:

  • 21. 

    Hypoallergenic cosmetic products don’t cause allergic reactions.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Hypoallergenic cosmetic products can still cause allergic reactions, despite the common belief that they do not. The term "hypoallergenic" implies that the product is less likely to cause an allergic reaction compared to regular products, but it does not guarantee that it won't cause any reactions at all. People with sensitive skin or specific allergies may still experience adverse reactions to hypoallergenic products. Therefore, the statement that hypoallergenic cosmetic products don't cause allergic reactions is false.

    • D.

      Conditioning agent 

    Correct Answer
    A. Surfactant 
    Explanation
    A surfactant is the prime ingredient in shampoo. Surfactants are responsible for the cleansing action of shampoos by reducing the surface tension between water and oil on the scalp and hair. They help to remove dirt, oil, and other impurities from the hair and scalp, making them an essential component in shampoo formulations. Humectants help to retain moisture in the hair, coloring agents provide color to the shampoo, and conditioning agents help to improve the texture and manageability of the hair. However, the main active ingredient that gives shampoo its cleansing properties is the surfactant.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    HC's (Hydrocortisone creams) and FC's (Fatty creams) are commonly used to treat sunburns because they have soothing and anti-inflammatory properties.

      Resins

    • C.

      Solvent

    • D.

      Pigment 

    Correct Answer

Resins are film-forming substances that help the nail polish adhere to the nail surface and provide a smooth and glossy finish. They also contribute to the durability and chip resistance of the nail lacquer. Plasticizers, solvents, and pigments are important components in nail lacquer, but they do not specifically provide adhesion and gloss like resins do.
