## Abstract

A cleansing composition is provided for removing waxy makeup, and for cleansing the skin with excellent rinse speed and after-feel. The inventive composition is also transparent and stable to phase separation and includes specific amounts of high average HLB nonionic surfactants, specific alkyl mono esters, hydrocarbon oils and polyol(s) and in a preferred embodiment contains very low levels of or no silicone oils.

## Claims

### Claim 1

A cleansing composition comprising:
a. 10 to 25 wt. % of nonionic surfactant(s) collectively having a weight average HLB greater than 10.8,
wherein HLB average is Σ (nonionic surfactant HLB×concentration)/total nonionic surfactant concentration),
wherein nonionic surfactants do not include linear and/or branched C5-C20 alkyl mono ester(s) with a molecular weight of 320 or below;
b. 20 to 40 wt. % of linear and/or branched C5 to C20 alkyl mono ester(s) where the molecular weight of the ester(s) is/are less than 320, wherein the alkyl monoester(s) is one or more of the following: isodecyl neopentanoate, ethylhexyl isononanoate, isopropyl myristate, blends thereof,
c. 25 to 40 wt. % of hydrocarbon oil(s);
d. 8 to 30 wt. % polyol(s); and
e. 1 to 10 wt. % of water.

### Claim 2 (depends on 1)

The composition of claim 1 wherein the alkyl mono ester(s) have an average frictional coefficient upon application to the skin of less than 0.3 MIU where MIU is calculated using the friction μ measured over a distance x, using KES-SE friction tester.

### Claim 3 (depends on 1)

The composition of claim 1 further comprising less than 1.0 wt. % of silicone oil(s).

### Claim 4 (depends on 1)

The composition of claim 1 wherein at least 50% the total alkyl mono ester(s) is/are selected from Isodecyl Neopentanoate, Ethylhexyl Isononanoate, Isopropyl Myristate or blends thereof.

### Claim 5 (depends on 1)

The composition of claim 1 wherein at least 50 wt. % the total polyol(s) are selected from propylene glycol, 1,3-Butylene Glycol, Dipropylene glycol or blends thereof.

### Claim 6 (depends on 1)

The composition of claim 1 wherein the composition is transparent.

### Claim 7

(canceled)

### Claim 8

(canceled)

### Claim 9 (depends on 1)

The composition of claim 1 wherein the composition is a make-up remover composition.

### Claim 10 (depends on 1)

A packaged product for removing makeup from the skin comprising the composition of claim 1 contained within a pump dispenser.
