摘要:
Described are diester amine adducts of formula (1) wherein R1, R2, R3, R4 are each independently of one another C4-C22alkyl; C2-C22alkenyl; or C5-C7cycloalkyl; X1 and X2 are each independently of the other hydrogen, C1-C4alkyl; C2-C4hydroxyalkyl or C2-C4hydroxyhaloalkyl; Y is a radical of formula (1b); A1 is C2-C3alkylene or 2-hydroxy-n-propylene; X3 is hydrogen; C1-C4alkyl, C2-C4hydroxyalkyl; or C2-C4hydroxyhaloalkyl; (A) is an asymmetrical carbon atom in the R- or S-configuration, wherein, if C1=R, C2=R; C1=S, C2=S; and C1=R; C2=S; m1 is 1 or 2; and n is an integer from 1 to 4; p is 0 or 1; which adducts may be in the form of free bases or ammonium salts. Said compounds are precursors of compounds having good complex-forming properties and are thus able to effectively bind heavy metal ions such as iron, zinc, magnesium or copper ions and to prevent metal-initiated oxidations after enzymatic or chemical cleavage. They have a plurality of uses, for example in foods, beverages, derusting and decalcification baths, as additives in liquids for cooling-water circuits, in personal-care products, as bleaching stabilizers, in cleaning agents and detergents, in the textile industry and also as soft handle agents for organic fibre materials.
摘要:
UV absorber compositions are described, comprising (a) from 1 to 99% by weight of a hydroxyphenyltriazine compound of formula (I) wherein R1, R2 and R3 are each independently of the others C1-C18alkyl; C2-C10,alkenyl; or phenyl-C1-C4 alkyl; R4 is hydrogen; or C1-C5alkyl; and (b) from 99 to 1% by weight of a further UV absorber selected from the group of (b) hydroxyphenyltriazines that are different from component (a), (b2) benzotriazoles, (b3) dibenzoylmethane derivatives and (b4) camphor derivatives. The compositions are suitable as UV filters in cosmetic compositions
摘要:
A description is given of symmetrical triazine derivatives of formula (1), wherein R1 and R2 are each independently of the other hydrogen; C1-C12alkyl, C1-C12alkoxy; and R3 is C1-C12alkyl; or C1-C12alkoxy. The easily accessible triazine derivatives are suitable for protecting ultraviolet-sensitive materials, in particular skin and hair of humans and animals, from the harmful effects of UV radiation.
摘要:
The present invention relates to new compounds of formula (I), wherein R1, R2, R3, R4, R5, R6, R7, and R8 independently from each other are hydrogen; C1-C18alkyl; C2-C18alkenyl; C5-C7, cycloalkyl; C1-C6alkylene-C5-C7, cycloalkyl; R9 is hydrogen; C1-C18alkyl; C2-C18alkenyl; C5-C7cycloalkyl; C1-C6alkylene-C5-C7cycloalkyl; C6-C10aryl; A is —S—; —O— or —NR10—, wherein R10 has the same meanings as R9; X is COOR11; CONR12R13; SO3, R14; or SO2NR15R16, wherein R11, R12, R13, R14, R15, and R16, have independently from each other the same meanings as R9; to their preparation and to their use as UV absorbers in cosmetic and pharmaceutical formulations.
摘要:
The invention relates to cleaning compositions comprising (a1) a phenolic antioxidant of the formula (1) and/or (2); and/or (a2) an antioxidant of the formula (3); and (b) a surfactant comprising a long alkyl or alkenyl chain. The antioxidants used according to the invention have excellent reactivity, good stability to hydrolysis, particularly in an alkaline medium, and, because of their solubility, can be easily incorporated into the soap formulations.

摘要:
A nanodispersion comprises (a) a membrane-forming molecule, (b) a coemulsifier and (c) a lipophilic component, in pharmaceutical end formulations, the nanodispersion being obtainable by (α) mixing the components (a), (b) and (c) until a homogeneous clear liquid is obtained, and (β) adding the liquid obtained in step (α) to the water phase of the pharmaceutical end formulations, where steps (α) and (β) may be carried out without high energy mixing or homogenization. The nanodispersions prepared according to this invention are suitable as transport vehicles for pharmaceutical active agents.
