Abstract

Treatment composition that include certain plant rosin materials and one or more benefit agents, for example fragrance materials, where the plant rosin materials are certain plant rosin esters and/or have certain characteristics, such as certain softening points, acid numbers, and/or color grades. Related methods of making and using such compositions.

First claim

What is claimed is:

1. A treatment composition comprising a plant rosin material and one or more benefit agents,
wherein the plant rosin material is a plant rosin ester material,
wherein the plant rosin ester material comprises, on average, from about two to about six moles of ester groups per mole of plant rosin ester material, and
wherein the plant rosin material comprises a gum rosin ester; and

wherein the one or more benefit agents comprises fragrance material.

2. The treatment composition according to claim 1 , wherein the plant rosin ester material is derived from a plant rosin and an alcohol,
wherein the alcohol comprises from two to six carbon atoms.

3. The treatment composition according to claim 2 , wherein the alcohol from which the plant rosin ester material is derived is selected from the group consisting of glycerol, pentaerythritol, and mixtures thereof.

4. The treatment composition according to claim 3 , wherein the alcohol from which the plant rosin ester material is derived is glycerol.

5. The treatment composition according to claim 1 , wherein the plant rosin ester material is characterized by one or more of the following:
a) a softening point of from about 50° C. to about 120° C.; and/or
b) an acid number of from 0 to about 100; and/or
c) a color grade of from about 1 to about 10, as graded on the Gardner Color standard number.

6. The treatment composition according to claim 5 , wherein the plant rosin ester material is characterized by one or more of the following:
a) a softening point of from about 60° C. to about 100° C.; and/or
b) an acid number of from 0 to about 20; and/or
c) a color grade of from about 1 to about 6, as graded on the Gardner Color standard number.

7. The treatment composition according to claim 1 , wherein the plant rosin material is characterized by a softening point of from about 60° C. to about 100° C., and by an acid number of from 0 to about 80.

8. The treatment composition according to claim 1 , wherein the plant rosin material is at least partially hydrogenated.

9. The treatment composition according to claim 1 , wherein the plant rosin material additionally comprises a material selected from the group consisting of wood rosin, tall oil rosin, derivatives thereof, and mixtures thereof.

10. The treatment composition according to claim 1 , wherein the plant rosin material and the one or more benefit agents are present in a weight ratio of from about 5:95 to about 95:5.

11. The treatment composition according to claim 1 , wherein the one or more benefit agents further comprises a material selected from the group consisting of silicone oils, waxes, hydrocarbons, higher fatty acids, essential oils, lipids, skin coolants, vitamins, sunscreens, antioxidants, glycerine, malodor reducing agents, odor-controlling materials, antistatic agents, softening agents, insect and moth repelling agents, colorants, optical brighteners, whiteness enhancers, defoamers, anti-foaming agents, UV protection agents for fabrics and skin, sun fade inhibitors, anti-allergenic agents, water proofing agents, skin care agents, natural actives, aloe vera, vitamin E, shea butter, cocoa butter, brighteners, antiperspirant actives, emollients, skin sensates, and mixtures thereof.

12. The treatment composition according to claim 1 , wherein the treatment composition comprises particles,
wherein the particles comprise the plant rosin material and the fragrance material.

13. The treatment composition according to claim 1 , wherein the treatment composition further comprises an adjunct ingredient,
wherein the adjunct ingredient is selected from an amine, a surfactant system, a water-binding agent, a sulfite, fatty acids and/or salts thereof, enzymes, encapsulated benefit agents, soil release polymers, hueing agents, builders, chelating agents, dye transfer inhibiting agents, dispersants, enzyme stabilizers, catalytic materials, bleaching agents, bleach catalysts, bleach activators, polymeric dispersing agents, soil removal/anti-redeposition agents, polymeric dispersing agents, polymeric grease cleaning agents, brighteners, suds suppressors, dyes, hueing agents, free perfume, a perfume delivery system, structure elasticizing agents, fabric softening agents, carriers, fillers, hydrotropes, organic solvents, anti-microbial agents and/or preservatives, neutralizers and/or pH adjusting agents, processing aids, fillers, rheology modifiers or structurants, opacifiers, pearlescent agents, pigments, anti-corrosion and/or anti-tarnishing agents, and mixtures thereof.

14. The treatment composition according to claim 13 , wherein the adjunct ingredient comprises a surfactant system, fabric softening agents, or combinations thereof.

15. The treatment composition according to claim 1 , wherein the treatment composition further comprises an amphiphilic polymer.

16. The treatment composition according to claim 1 , wherein the treatment composition is a liquid.

17. The treatment composition according to claim 1 , wherein the treatment composition is a fabric care composition, a hard surface cleaner composition, a dish care composition, a hair care composition, a body cleansing composition, or a mixture thereof.

18. The treatment composition according to claim 1 , wherein the treatment composition is a fabric care composition.

19. The treatment composition according to claim 1 , wherein the treatment composition is a fabric care composition, wherein the fabric care composition is a fabric conditioning composition.

20. A method of treating a surface, the method comprising the step of contacting the surface with the treatment composition according to claim 1 , optionally in the presence of water.

21. A treatment composition comprising:
a plant rosin material,
wherein the plant rosin material comprises a gum rosin ester, and
wherein the plant rosin material is characterized by at least one of the following characteristics:
a) a softening point of from about 50° C. to about 120° C.;
b) an acid number of from 0 to about 100; and/or
c) a color grade of from about 1 to about 10, as graded on the Gardner Color standard number scale;

the treatment composition further comprising one or more benefit agents,
wherein the one or more benefit agents comprises fragrance material.
