Worked Solution & Example Answer:Skin care products contain a mixture of polar covalent, non-polar covalent and ionic compounds - Scottish Highers Chemistry - Question 8 - 2017
Step 1
Explain the role of water in skin care products
Answer
Water is a polar solvent that helps dissolve other ingredients in skin care formulations. It facilitates the even distribution of active compounds and allows for easy application on the skin. Additionally, water aids in hydration, which is essential for maintaining skin health and elasticity.
Step 2
Explain the role of fats and oils in skin care products
Answer
Fats and oils serve multiple purposes in skin care products. They act as emollients, providing a moisturizing effect that helps to soften the skin. These compounds also form a barrier on the skin to reduce water loss, ensuring that hydration is retained. Furthermore, oils can have beneficial properties, such as nourishing the skin or providing anti-inflammatory benefits.
Step 3
Explain the role of antioxidants in skin care products
Answer
Antioxidants play a crucial role in protecting the skin from oxidative stress caused by free radicals. These compounds help to neutralize free radicals, which can lead to premature aging and skin damage. Common antioxidants used in skin care include vitamins C and E, which not only protect but can also brighten the skin and improve its overall appearance.
Step 4
Explain the role of minerals in skin care products
Answer
Minerals such as zinc and magnesium can contribute to skin health by offering anti-inflammatory and antibacterial properties. Zinc, for example, is often used in sunblocks and healing products for its ability to soothe the skin and promote healing. Additionally, minerals can assist in balancing skin tone and aiding in skin repair.
Step 5
Explain the role of sun block in skin care products
Answer
Sun block is essential for protecting the skin from harmful ultraviolet (UV) rays. It contains chemical or physical filters that either absorb or reflect UV radiation, thus preventing sunburn and reducing the risk of skin cancer. Regular use of sun block is vital in maintaining skin health and preventing photo-aging.
