Octyl Methoxycinnamate (OMC)
Octyl Methoxycinnamate (OMC)
OMCX is an effective UV-B filter. UV-A radiation (320-400nm) is linked with the loss of skin elasticity, wrinkling and premature ageing, whilst the more powerful UV-B radiation (290-320nm) is linked to sunburn, cell damage and skin cancer. OMCX is soluble in most organic solvents facilitating good incorporation particularly into high SPF skin care and sunscreen product where a level of water resistance is desirable.
OMCX is compatible with most of the cosmetic ingredients. For total UV range protection, OMCX is formulated with Avobenzone (UV-A blocking). OMCX is highly effective UV-B filter which absorbs the UV-B rays in the range of 290-340nm.
