How do you formulate moisturizer?
The composition below is representative:
- Water (60-75%)
- Humectants (3-20%): Glycerin is most commonly used but can be quite tacky when used over 5%.
- Emollients (5-15%): historically most hand and body lotion formulations used Petrolatum due to its ability to reduce TEWL or skin moisture loss.
What are the evaluation parameters of cream?
All of the prepared formulations of moisturizing cream were evaluated for its physicochemical parameters. Further, the optimized formulation and selected commercial moisturizer compared and evaluated for its physicochemical parameters like pH, particle size, spreadability, viscosity and in vitro occlusivity test.
What is the important characteristics in formulation of lotion?
The key components of a skin care lotion, cream or gel emulsion (that is mixtures of oil and water) are the aqueous and oily phases, an emulsifier to prevent separation of these two phases, and, if used, the drug substance or substances.
What are the various methods of preparation of creams?
A cream is basically a mixture of oil and water. As you know oil does not readily dissolve or disperse in water, so to allow this to happen, a dispersing agent called an emulsifier is added to the mixture. A cream is therefore a type of emulsion, made of a water phase and an oil phase.
What does a moisturizer contains?
Ingredients in moisturizers
- Water. Most moisturizers are oil-in-water emulsions, so by definition that makes them creams and lotions.
- Lactic acid.
Why occlusive potential of ingredients are evaluated in creams?
The instruments help in evaluating moisturizing capacity of the products and screening of raw materials used in the formulation. (c) Occlusive potential of ingredients. It provides information on the water content present in stratum corneum and also acts as a screening device for moisturizing ingredients.
How pastes are differing from creams and ointments?
Difference between Pastes and Ointments: Pastes are very thick and stiff; whereas, ointments are soft semisolid preparations. Pastes are less greasy; whereas, ointments are greasy. Pastes are generally applied with a spatula or are spread on lint; whereas, ointments are simply applied on the skin.
How are active ingredients added in preparation of creams?
are normally supplied in the form of a cream or ointment as this provides an effective means of delivering the active ingredient directly to the required area. Active ingredients are dispersed in either phase or added when the emulsion has been formed and allowed to cool.
How do you make gel based products?
- Dissolve 1/2 teaspoon of gelatin in warm water.
- Add more gelatin as needed to reach the desired consistency, and stir.
- Cool your hair gel in the refrigerator for about three hours, or until set.
- Add a few drops of your favorite essential oil, if you’d like, and mix well.
How are moisturizing creams evaluated for their physicochemic parameters?
All of the prepared formulations of moisturizing cream were evaluated for its p hysicochemical p arameters. Further, the optimized formulation and selected commercial moisturizer compared and evaluated for its physicochemic al parameters lik e pH, particle s ize, spreadabili ty, viscosity and in vitro occlusivity test.

What are the factors that affect the moisturizing effect of Formula-tions?
The moisturizing effect of formula- tions may be influenced by many factors, such as type and concentration of the active substances used, as well as the composition of the vehicle Medicinal plants of the lily family (Liliaceae), genus Aloe, have been used for the treatment of skin diseases for more than 2000 years (10).
What is the difference between moisturiser and lotion?
Lotions, creams, body butters and moisturisers are all emulsions and are made the same way with mostly the same ingredients. Lotions and moisturisers tend to be more fluid than creams or body butters so may contain less oils, less emulsifier and less thickener.
