Creams: Types, Advantages, Disadvantages, Pharmaceutics Notes PDF
Creams are viscous liquid or semisolid emulsions intended for application to the skin i.e. for external use
Creams are of two types, aqueous creams and oily creams.
In the case of aqueous creams the emulsions are oil-in-water type and in the case of oily creams emulsions are of water-in-oil type.
Due to the presence of water-soluble bases they can be easily removed from the skin.
The aqueous creams have a tendency to grow bacterial and mould growth, therefore a preservative must be added in their formulation.
e.g. cetomacrogol cream, cetrimide cream, hydrocortisone cream, zinc cream BPC.
1. Creams are more acceptable to the patients because they are less greasy and are easier to apply.
2. They interfere less with skin functions.
3. o/w type of creams (superior to w/o type) can be rubbed onto the skin more readily and are easily removed by washing. w/o can be spread more evenly.
4. o/w type of cream are less likely to soil clothes.
5. Evaporation of water from o/w type of cream causes a cooling sensation.
6. o/w creams absorb the discharges from the wound (liquid exudate) very quickly.
7. w/o creams (e.g. cold creams) restricts evaporation from the skin, it can be used on non-weeping surfaces to prevent dehydration ( in the dry season), restore suppleness (softness)
Creams like cold cream restrict evaporation from the skin, it can be used on non-weeping surfaces to prevent dehydration ( in dry season), restore suppleness (softness) – this property is said to be ‘emollient’
1. Since it is a semisolid preparation and contains oil in large amounts, some of which are inedible, hence creams are not used for internal use. Basically creams are meant for application onto the skin.
2. The aqueous phase is prone to the growth of moulds and bacteria hence preservatives should be used.
3. Sometimes rancidification of oils take place.
Advantages of cold cream
- Moisturization: Cold creams are renowned for their excellent moisturizing properties. Their oil-based formulation helps lock in moisture, preventing dehydration and dryness.
- Gentle Cleansing: They efficiently remove dirt, makeup, and impurities while being gentle on the skin. This dual action of cleansing and moisturizing is particularly beneficial for dry or sensitive skin.
- Barrier Protection: The thick consistency of cold creams forms a protective barrier on the skin, shielding it from harsh environmental factors like wind and cold weather.
- Versatility: They can be used on various skin types and even as an effective eye makeup remover due to their emollient nature.
Disadvantages of cold cream
- Pore Clogging: The rich texture of cold creams might not suit oily or acne-prone skin, potentially leading to clogged pores and breakouts.
- Heavy Feel: Some individuals find the thick consistency uncomfortable or greasy, especially in warmer climates.
- Potential Irritation: Fragrances or certain ingredients in cold creams could trigger allergic reactions or irritation in sensitive skin types.
Advantages of melaglow cream
- Targeted Action: Melaglow cream is specifically formulated to address pigmentation issues, such as dark spots, uneven skin tone, and hyperpigmentation.
- Active Ingredients: It contains compounds like Kojic acid, Arbutin, and Vitamin C, known for their skin-brightening properties, helping to reduce dark spots and promote a more even complexion.
- Suitability: It’s generally well-tolerated by most skin types seeking to combat pigmentation concerns.
Advantages of Ice Cream:
- Pleasure and Enjoyment: Ice cream is a mood-booster, providing a sensory delight through its taste, texture, and temperature. Its indulgent nature often brings comfort and happiness.
- Nutritional Value: Depending on ingredients, it can offer essential nutrients like calcium, protein, vitamins (such as B vitamins), and minerals, contributing to bone health and overall nutrition.
- Energy Source: Ice cream provides a quick source of energy due to its sugar and fat content, making it a convenient snack for an energy boost.
- Creativity and Variety: The vast array of flavors and combinations allows for creative exploration and innovation, catering to diverse tastes and preferences.
