Abstract

An emollient composition comprising at least 5-30% by weight polyethylene, 0-60% by weight petrolatum, and 0-50% octyl palmitate. These emollient compositions may be used as emollient carriers for various materials, such as fragrances and pigments or dyes, to be externally applied to the skin. These emollient compositions may be formed into particulate shapes, such as spheres, for subsequent use in cosmetic products.

Claims

1. A composition comprising solid particles comprising polyethylene, petrolatum and octyl palmitate, said solid particles carrying an active ingredient selected from the group consisting of fragrances, vitamins, medicaments, botanical extracts, and ultraviolet radiation absorbers, wherein the polyethylene, petrolatum and octyl palmitate are blended, or dissolved, in each other.

2. The composition of claim 1 wherein said particles are dyed or pigmented compositions carry an active ingredient selected from the group consisting of fragrances, vitamins, medicaments, botanical extracts and ultraviolet radiation absorbers.

3. The composition of claim 1 wherein said polyethylene comprises at least 10% by weight of said particles.

4. The composition of claim 2 wherein said polyethylene comprises at least 10% by weight of said particles.

5. The composition of claim 1 comprising said particles dispersed in a flowable continuous phase carrying medium that is not a solvent for said particles.

6. The composition of claim 2 comprising said particles dispersed in a flowable continuous phase carrying medium that is not a solvent for said particles.

7. The composition of claim 1 comprising said particles dispersed in a gel carrying medium that is not a solvent for said particles.

8. The composition of claim 2 comprising said particles dispersed in a gel carrying medium that is not a solvent for said particles.

11. The composition of claim 1 wherein said solid particles comprise spheres.

12. The composition of claim 2 wherein said solid particles comprise spheres.

9. A composition comprising solid particles comprising polyethylene, petrolatum and octyl palmitate, said solid particles carrying at least one active ingredient selected from the group consisting of fragrances, vitamins, medicaments, botanical extracts, cosmeceuticals and ultraviolet radiation absorbers, wherein the polyethylene, petrolatum and octyl palmitate are blended, or dissolued, in each other.

10. The composition of claim 9 wherein said particles are dyed or pigmented and carry an active ingredient selected from the group consisting of fragrances, vitamins, medicaments, botanical extracts, cosmeceuticals and ultraviolet radiation absorbers.

13. The composition of claim 9 wherein said solid particles comprise spheres.

14. The composition of claim 10 wherein said solid particles comprise spheres.

15. A method for moisturizing skin comprising the steps of:

a. providing an emollient composition comprising polyethylene, petrolatum, and octyl palmitate, wherein the polyethylene, petrolatum and octyl palmitate are blended, or dissolved, in each other;

b. applying an amount of the emollient to a portion of the skin; and

c. working the emollient composition into the skin.

16. The method according to claim 15 wherein the emollient composition has a solid feel.

17. The method according to claim 16 wherein the solid feel emollient composition is in a generally spherical form.

18. The method according to claim 16 where the step of working the emollient composition into the skin is continued until the solid feel emollient composition has disappeared to the touch.

19. The method according to claim 17 where the step of working the emollient composition into the skin is continued until the solid feel emollient composition has disappeared to the touch.

20. The method according to claim 15 wherein the emollient composition is used in a cosmetic field selected from the group consisting of baby shampoos, baby lotions, baby oils, baby powders, baby creams, bath oils, bath tablets, bath salts, bubble baths, bath capsules, eye makeup, eyebrow pencils, eyeliners, eye shadows, eye lotions, eye makeup removers, mascara, fragrance preparations, colognes, toilet waters, perfumes, dusting powders, talcum powders, sachets, hair conditioners, hair sprays, hair straighteners, permanent waves, hair rinses (non-coloring), shampoos (non-coloring), hair tonics, hair dressings, wave sets, hair coloring preparations, hair dyes, hair colors, hair tints, hair rinses (coloring), hair color sprays, hair lighteners with color, hair bleaches, blushers, face powders, foundations, leg and body paints, lipsticks, makeup bases, rouges, makeup fixatives, manicuring basecoats, manicuring undercoats, cuticle softeners, hair creams, hair lotions, nail extenders, nail polishes, nail enamels, nail polish and enamel removers, oral hygiene products, dentifrices, bar soaps, detergents, deodorants, shaving preparations, aftershave lotions, beard softeners, men'"'"'s talcum, preshave lotions, shave creams, shaving soaps, skin creams, skin lotions, skin powders, skin sprays, cold creams, cleansing lotions, cleansing liquids, cleansing pads, depilatories, face and neck scrubs, body and hand scrubs, leg and foot scrubs, foot powders, foot sprays, moisturizing creams, moisturizing lotions, night creams, paste masks, mud packs, skin fresheners, suntan gels, suntan creams, suntan liquids, indoor tanning preparations, and sunless tanning preparations. adiation absorbers.
