Definitions

• the present invention relates to self-foaming and / or foam-like cosmetic and dermatological preparations, in particular skin-care cosmetic and dermatological preparations.
• Foams or foam-like preparations belong to the disperse systems.
• Emulsions are two- or multi-phase systems of two or more liquids that are insoluble or only slightly soluble in one another.
• the liquids pure or as solutions
• the liquids are present in an emulsion in a more or less fine distribution, which is generally only of limited stability.
• Foams are structures made of gas-filled, spherical or polyhedral cells, which are delimited by liquid, semi-liquid, highly viscous or solid cell bridges.
• the cell bridges connected via so-called nodes, form a coherent framework.
• the foam lamellae (closed-cell foam) stretch between the cell bars. If the foam lamellae are destroyed or flow back into the cell webs at the end of foam formation, an open-cell foam is obtained.
• Foams are also thermodynamically unstable, since surface energy can be obtained by reducing the surface. The stability and therefore the existence of a foam depends on the extent to which it can prevent its self-destruction.
• Cosmetic foams are generally dispersed systems composed of liquids and gases, the liquid being the dispersant and the gas being the dispersed substance. Foams made from low-viscosity liquids are temporarily stabilized by surface-active substances (surfactants, foam stabilizers). Because of their large inner surface, such surfactant foams have a strong adsorption capacity, which is used, for example, in cleaning and washing processes. Accordingly, cosmetic foams are used in particular in the areas of cleaning, for example as shaving cream, and hair care.
• surfactants foam stabilizers
• foam gas is blown into suitable liquids, or foam formation is achieved by vigorous beating, shaking, spraying or stirring the liquid in the gas atmosphere in question, provided that the liquids contain suitable surfactants or other surface-active substances (so-called foaming agents) that besides interfacial activity also possess a certain film-forming ability.
• suitable surfactants or other surface-active substances so-called foaming agents
• Cosmetic foams have the advantage over other cosmetic preparations in that they allow a fine distribution of active ingredients on the skin.
• cosmetic foams can generally only be achieved by using special surfactants, which moreover are often not very kind to the skin.
• Post-foaming preparations are often in special embodiments such as post-foaming shaving gels or the like.
