ANTI AGEING AGENTS have yet to be discovered. However, many factors involved in physical deterioration have been identified, and some palliative measures to slow these processes, particularly in relation to cardiovascular disease, are well known, such as dietary restriction, exercise etc. There have been many investigations of the effects of placental extracts and other hormonal treatments but the results are unconvincing. More recently, there have been hopeful results from studies of antioxidants, superoxide dismutase modifiers and free-radical scavengers.

UV light below 380 nm, photoinduced hydrophilic conversion and photo-catalytic properties, it can be used as an anti-ageing agent for NR and can increase its lifetime. 

A typical emulsion polymerization formulation comprises four basic ingredients 1) monomer, 2) dispersion medium, 3) emulsifier, 4) initiator. Further auxiliaries, such as chain transfer agents, buffers, acids, bases, anti-aging agents, biocids, etc., can be used. In emulsion polymerization process, a monomer or a mixture of monomers is emulsified in the presence of an aqueous solution of an emulsifier in a suitable container. The monomer is thus present almost entirely as emulsion droplets dispersed in water. The initiator causes the monomer molecules to polymerize within a certain temperature range. When the polymerization is complete, a stable colloidal dispersion of polymer particles in an aqueous medium (the latex) will remain. 

Alkyl derivatives of dihydroquinoline are the earliest and best studied anti-aging agents, which have found wide use for the stabilization of polymers.

Modern rubber materials consist of approximately 60% polymers. The other part consists of vulcanization agents, softeners, accelerators, anti-aging agents and other chemicals. These additions are necessary to achieve the desired properties of the final product. A variety of methods exist for vulcanization. 

Chemicals that protect elastomers against various damaging external influences are called anti-aging agents or also antidegradants. Products added by the manufacturer to protect the storage stability of crude rubber are called stabilizers by contrast. 

At present, oligosaccharides are used in a number of moisturizing formulas due to their hydrating and fihnogenic actions, in products to normalize the desquamation of the stratum corneum and as anti-ageing agents (Schaeffer and Brooks, 1992). 

Not to be forgotten in this section, is the unsaponifiable fraction, which corresponds to the non-glyceride constituents of oils. In general, oils contain between 0.2 and 1.5% unsaponifiable compounds. The relevance of unsaponifiables is based on their chemical composition. They are employed in cosmetics as antioxidant and vitamin actives because of their tocopherol and carotene content and as anti-ageing agents—their sterol content. We would like to emphasize the cosmetic properties of the unsaponifiable fractions of soya, olive and avocado oils.

The production of polymer dispersions by emulsion polymerization requires deionized water, free-radical-polymerizable monomers, emulsifiers and/or protective colloids and initiators. Further auxiliaries, such as chain transfer agents, buffers, acids, bases, anti-aging agents, biocides, etc., can be used.
