## Abstract

Substantive, biodegradable, antimicrobial—diamidoquats of Formula I, comprising a quaternary ammonium center and amide functionality and having conditioning properties along with good antimicrobial efficacy wherein, R and R1 are selected from C6 to C24. Home care, fabric care composition comprising novel compounds are effective even at lower dosage compared to other traditional conditioning compounds. wherein, R and R1 may or may not be same and are selected from C6 to C24 straight or branched chain alkyl or alkenyl residue.

## Claims

### Claim 1

A substantive diamidoquat molecule of Formula I,
wherein R and R1 may or may not be the same and are selected from C6 to C24 straight or branched alkyl chains or alkenyl residues.

### Claim 2 (depends on 1)

The diamidoquat molecule of claim 1, wherein R and R1 are each C12 to C18.

### Claim 3 (depends on 1)

The diamidoquat molecule of claim 1, wherein the molecule has a fabric softening and antimicrobial property.

### Claim 4 (depends on 1)

A home care composition comprising the diamidoquat molecule of claim 1.

### Claim 5 (depends on 4)

The home care composition of claim 4, further comprising one or more components selected from the group consisting of emulsifiers, thickening agents, fabric conditioning agents, surfactants, rheology modifiers, stabilizers, color, and fragrance.

### Claim 6 (depends on 4)

The home care composition of claim 4, comprising the diamidoquat molecule of Formula I in an amount ranging from 3 to 60% by weight of the composition.

### Claim 7 (depends on 6)

The home care composition of claim 6, comprising the diamidoquat molecule of Formula I in an amount ranging from 3 to 20% by weight of the composition.

### Claim 8 (depends on 4)

The home care composition of claim 4, wherein the composition is selected from a fabric softener, a hard surface cleaner, a dish wash, and an industrial and institutional cleaning composition.
