Abstract

A personal care composition is provided with a silicone compound and being aesthetically modified for improved skinfeel with a quaternary ammonium salt, the salt having a structure AB, wherein A is a cationic charged component, B is an anionic charged component, and A has one quaternized nitrogen atom, at least two hydroxyl groups and a molecular weight no higher than about 250.

Claims

1. A personal care composition comprising:

(i) from about 0.05% to about 30% by weight of a dihydroxypropyl quaternary ammonium salt of structure AB,

wherein

A is a cationic charged component of the salt AB,

B is an anionic charged component of the salt AB, and

A has a single quaternized nitrogen atom, at least two hydroxy groups and a molecular weight no higher than about 250;

(ii) from about 0.05 to about 50% by weight of a silicone.

2. The composition according to claim 1 wherein the quaternary ammonium salt is a dihydroxypropyltri(C₁-C₃ alkyl) ammonium salt.

3. The composition according to claim 2 wherein the salt is dihydroxypropyltrimonium chloride.

4. The composition according to claim 1 which is selected from the group consisting of leave-on skin lotions and creams, shampoos, hair conditioners, shower gels, toilette bars, antiperspirants, deodorants, dental products, shave creams, depilatories, lipsticks, foundations, mascara, sunless tanner and sunscreen lotions.

5. The composition according to claim 1 wherein the silicone is a cyclomethicone.

6. The composition according to claim 1 wherein the silicone is dimethicone.

7. The composition according to claim 1 wherein the silicone is a dimethicone/vinyl dimethicone crosspolymer.

8. A method for moisturizing human body parts while still providing an aesthetically pleasing skinfeel comprising topically applying to the human body parts a personal care composition comprising from about 0.05 to about 30% by weight of a quaternary ammonium salt which is a salt of structure AB

wherein

A is a cationic charged component of the salt AB

B is an anionic charged component of the salt AB, and

A has a single quaternized nitrogen atom, at least two hydroxy groups and a molecular weight no higher than about 250;

and

from about 0.05 to about 50% of silicone by weight of the composition.
