Pharmaceutical creams contain both oil and water. Both are found in stores, products, creams, conditioners. They all contain oil and water but when they are not shaken some of them create layers inside of their respective bottles. The consumer then inhales the separated layers once it is opened, so mixing or shaking the solution is best. Pharmaceutical creams such as the anti aging Beverly Hills Lift + Firm Cream have certain types of mixtures. Creams in the market are either (o/w) oil-in-water or (w/o) water-in-oil. There is a huge difference in the type of mixture which determines how the active stimulant based ingredient is released and its effectiveness.
We will summarize how the oil-in-water process works. Oil droplets are prepared in water form. This type of formulas are found in moisturizers in both day and night creams as well as products that have been enhanced due to steroids. Homogenized milk is also a common w/o solution but it’s usually considered a food product. Also, the skin’s stratum is invaded by the o/w based creams which is achieved by having the attribute of being thick an affecting a direct area. All mixes needs stability by a emulsifier to gain a great smooth attribute. Some ointments needs ingredients such as polysorbate so they can be effective in an o/w formula.
There are also o/w formulas. There is no direct answer of to which is better. It all depends on the person who is using it and how effective it is on their skin. Since it’s being made a different way, it depends also on what ingredients are they using. It does present multiple challenges to how much of availability of the ingredients there is.
4 things that are crucial to all type of pharmaceutical creams is the thickening, stability, uniform distribution, and thickening. The consistency should be the same from one bottle to the next. These are all things that should be highlighted when choosing a cream for personal care.
