The invention relates to an alcohol-free beauty or pharmaceutical foam composition comprising water, a hydrophobic solvent, a floor-energetic agent, a gelling agent, an energetic component chosen from the group of urea, hydroxy acid and a therapeutic enhancer and a propellant. Appropriate pores and skin lightening or whitening brokers embrace those identified within the artwork, together with hydroquinone, azelaic acid and different associated dicarboxylic acids, and salts and derivatives thereof, retinoids, kojic acid, arbutin, nicotinic acid and nicotinic acid precursors, salts and derivatives, ascorbic acid and salts and derivatives thereof (e.g., magnesium ascorbyl phosphate or sodium ascorbyl phosphate), and herbal extracts (e.g., mulberry extract, placental extract).
A selected embodiment in accordance with the present invention contains inserting the composition of the current invention on a patch, regulating residence of an energetic ingredient in the pores and skin tape or the pores and skin-contact compartment of a transdermal supply apparatus and making use of such object onto the skin, to be able to attain effective superficial remedy or enhanced penetration of the drug into the pores and skin or by the pores and skin.
In a number of embodiments of the current invention, the hydrophobic solvent is included within the foamable composition at a concentration of 5% to about 10% (Class A), or 10% to about 20% (Class B), or about 20% to about 50% (Class C). The surface-active agent concentration is about zero.1% to about 5%; the focus of the gelling agent is zero.01% to about 5% by weight and the liquefied gas propellant is included at a focus of about three% to about 18% of the total composition.
LEHR: Lou, I’m within the camp with Joe and Fred Singer and Dennis Avery, and I believe extra importantly, it is to have a look at the solar’s output, and lately, we’ve seen very, very low sunspot activity, and we are undoubtedly, in my thoughts, not only in a cooling interval, we’re going to be staying in it for a pair a long time, and I see it as a significant benefit, though I feel we will adapt to it. I’m hopeful that this alteration in the sun’s output will put some widespread sense into the legislature, not to cross any dramatic cap in commerce or carbon tax laws that will set us in a far deeper economic hole.
The beauty or pharmaceutical foamable composition in response to a number of embodiments of the current invention consists of water, a hydrophobic solvent, a floor-energetic agent and a gelling agent and a minimum of one energetic part chosen from the group of (1) urea in a focus of no less than 2%; (2) a hydroxy acid in a concentration of at the least 1%; and (3) a therapeutic enhancer in a concentration of at least 2%; and a liquefied gasoline propellant within the quantity of about 3-18% by weight of the overall composition.

The pharmaceutical service in line with the current invention can also be used to prepare cosmetics for beauty purpose by adding into skin care agents and fragrance. For the purpose of the present utility, the term alcohol free†refers to compositions that include not more than 7.5% by weight of any aliphatic alcohol, having one to 6 carbon atoms of their carbon spine, or no more than 7.5% by weight of any combination of such aliphatic alcohols.
conclusion
For the purpose of the current application, the time period alcohol free†refers to compositions that comprise not more than 7.5% by weight of any aliphatic alcohol, having one to six carbon atoms of their carbon spine, or not more than 7.5% by weight of any mixture of such aliphatic alcohols.
