Abstract: Brighteners for detergents consisting of a mixture of 4,4'-bis-(2-morpholino-4-anilino-1,3,5-triazinylamino)-stilbene-2,2'-d isulfonic acid-di-Na salt and from 5 to 50% by weight, calculated on said brightener, of another brightener of the formula +TR in the above formula, M is an alkali metal cation, preferably sodium, X is a group of the formula -COR2 or -SO2R3, R2 being C1-C8-alkyl and R3 being C1-C5-alkyl, C4-C8-cycloalkyl, phenyl or toluyl, Y is hydrogen or C1-C5-alkyl, A is C3-C6-alkylene, R1 is hydrogen, C1-C5-alkyl, C4-C8-cycloalkyl, or a group of the formula and Z is an anilino group, a chloroanilino group or a morpholino group. Said brightener mixtures are color-stable and do not show any green discoloration even after a prolonged storage in a moist atmosphere.

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: Novel beta-naphthyl derivs. contg. sulpho gps. are of formula (I):- (where R = H, a colourless cation or lower alkyl; M=H or a colourless cation; A= opt. substd. phenyl, diphenyl, alpha- or beta- naphthyl), and more specifically of formula (II):- (where R=H or lower alkyl; M = alkali metal or ammonium cation). Used as optical for natural and synthetic materials such as wool, silk, leather, cotton, paper, wood, rubbers, gutta percha, polyamides, polyurethanes, etc. but pref. for regenerated cellulose fibres, wool and synthetic polyamides. Also for use in detergent comps. Effective amts. are 0.01-2 (0.02-0.1)%.
