Abstract: Mixtures of optical brighteners containing 0.05 to 1% of a 4-benzoxazolystilbene derivative and 1 to 0.05% of a 1,4-bis-benzoxazolyl- or bis-benzthiazolyl-naphthalene derivative. These mixtures show a higher degree of whiteness than an equal amount of only one of the two components.

Abstract: 1,3-Butadienes which are substituted at both terminal carbon atoms with phenyl, naphthyl, theinyl or furyl groups or one benzoxazolyl group are useful as optical brighteners for detergents. The butadienes, some of which are known, can be obtained by HORNER syntheses.
