## Abstract

An emulsifier in powder form for animal feeds is described. A process for preparing the animal feed is also described.

## Claims

### Claim 1

A solid mixture comprising:
a solid composition in powder form comprising:
a carrier or support in powder form,
with at least one emulsifier incorporated, or adsorbed, or absorbed, or applied on an outer face of the carrier or support in powder form, the at least one emulsifier chosen from the group consisting of:
(i) a mixture comprising an ethoxylated castor oil and at least one vegetable olein;
(ii) a mixture comprising an ethoxylated castor oil, at least one vegetable olein and a propylene glycol;
(iii) a mixture of (i)-(ii),
and
a mineral inert comprising magnesium oxide with a content by weight of at least 95%, calcium oxide with a content by weight below 2.5% and the mineral inert further comprising silicon dioxide with a content by weight below 1%, and iron (III) oxide and aluminum oxide each with a content by weight below 0.04%;
wherein said solid mixture comprises said solid composition in powder form in an amount by weight from 5% to 30% and said mineral inert in an amount by weight from 70% to 95%.

### Claim 2 (depends on 1)

The solid mixture according to claim 1, wherein:
said castor oil is additive E484, and
said at least one vegetable olein is chosen from the group consisting of
oleic acid,
linoleic acid,
linolenic acid,
a triglyceride of oleic acid [(C17H33COO)3C3H5]— triolein,
a vegetable oil and
a mixture of said oleic acid, linoleic acid, linolenic acid, triglyceride of oleic acid.

### Claim 3 (depends on 1)

The mixture according to claim 1, wherein said carrier or support in powder form is present in said solid composition in an amount by weight from 20% to 50%, with respect to weight of the solid composition; and
wherein said at least one emulsifier which is incorporated or adsorbed or absorbed or applied on the outer surface is chosen from the group consisting of (i), (ii), and (iii), and is present in said solid composition in an amount by weight from 80% to 50%, with respect to weight of the solid composition.

### Claim 4 (depends on 1)

The solid mixture according to claim 1, wherein the carrier or support comprises at least one inorganic substrate chosen from the group consisting of:
silica;
bentonites;
zeolites;
sepiolite; and
perlite.

### Claim 5 (depends on 1)

The solid mixture according to claim 1, wherein the carrier or support comprises at least one vegetable substrate chosen from the group consisting of:
corn cob or corn fiber;
broad bean fiber; and
pea fiber, wood fiber or grape seed.

### Claim 6 (depends on 1)

The solid mixture according to claim 1, wherein said mixture comprises said solid composition in powder form in an amount by weight of 10%, and said mineral inert in an amount by weight of 90%.

### Claim 7 (depends on 1)

An animal feed comprising the solid mixture according to claim 1.

### Claim 8 (depends on 1)

A method comprising:
preparing an animal feed in solid form comprising the solid mixture according to claim 1, further comprising liquid and/or solid nutritive substances.

### Claim 9 (depends on 3)

The mixture according to claim 3, wherein said carrier or support in powder form is present in said solid composition in an amount by weight from 30% to 40%, with respect to the weight of the solid composition.

### Claim 10 (depends on 3)

The mixture according to claim 3, wherein said at least one emulsifier is present in said solid composition in an amount by weight from 70% to 60%, with respect to the weight of the solid composition.

### Claim 11 (depends on 4)
