Abstract

Biodegradable personal care compositions comprising 1,3-propanediol are provided, and the 1,3-propanediol in the composition is biologically derived. The compositions exhibit a lower anthropogenic CO 2 emission profile. Also provided are biodegradable personal care compositions comprising an ester of 1,3-propanediol. In these compositions, the ester can have at least 3% biobased carbon.

Claims (32)

1. A personal care composition comprising an ester of 1,3-propanediol, wherein the composition is biodegradable, wherein the ester is a monomer and comprises at least 3% biobased carbon, and wherein said composition has a lower anthropogenic CO 2 emission profile as compared to a biodegradable composition comprising an ester of 1,3-propanediol with a bio-based carbon content of 0%.

2. The composition of claim 1 , further comprising an active.

3. The composition of claim 1 , further comprising a solvent.

4. The composition of claim 1 , further comprising a conditioning agent.

5. The composition of claim 1 , wherein the ester has 100% biobased carbon.

6. The composition of claim 1 , wherein the ester has the formula R1-C(═O)—O—CH 2 —CH 2 —CH 2 —OH, wherein R1 is a linear or branched carbon chain of a length between about 1 and about 40 carbons.

7. The composition of claim 1 , wherein the ester has the formula R1-C(═O)—O—CH 2 —CH 2 —CH 2 —O—C(═O)—R2, wherein R1 and R2 are linear or branched carbon chains of a length between about 1 and about 40 carbons.

8. The composition of claim 1 , wherein the ester is selected from the group consisting of:

i. propanediol distearate, monostearate and a mixture thereof;

ii. propandiol dilaurate, monolaurate and a mixture thereof;

iii. propanediol dioleate, monooleate and a mixture thereof;

iv. propanediol divalerate, monovalerate and a mixture thereof;

v. propanediol dicaprylate, monocaprylate and a mixture thereof;

vi. propanediol dimyristate, monomyristate and a mixture thereof;

vii. propanediol dipalmitate, monopalmitate and a mixture thereof;

viii. propanediol dibehenate, monobehenate and a mixture thereof;

ix. propanediol adipate;

x. propanediol maleate;

xi. propanediol dibenzoate;

xii. propanediol diacetate; and

xiii. mixtures thereof.

9. The composition of claim 1 , further comprising 1,3-propanediol.

10. The composition of claim 9 , wherein the 1,3-propanediol has 100% biobased carbon.

11. The composition of claim 1 , wherein the personal care composition is a cosmetic.

12. The composition of claim 1 , wherein the personal care composition is selected from the group consisting of skin care composition, skin cleansing composition, make-up, facial lotion, cream moisturizer, body wash, body lotion, foot care products like foot cream, hand cream, lipstick, lip gloss, lip pencil, eyeshadow, gel eye color, eye liner, eye pencil, mascara, concealer, foundation, facial powder, liquid rouges, blush, deodorant, shaving cream composition, nail polish, gel polish removers, cuticle remover, cuticle cream, acne cream, acne cleansing scrub, toothpaste, shaving lotion, cream depilatory, lotion depilatory, wax depilatory, facial mask made with clay materials, anti-aging product, shampoo, hair care products like conditioner, hair treatment cream, styling gel, styling foam, hair mousse, hair spray, set lotion, blow-styling lotion, hair color lotion and dyes, hair bleaching cream hair relaxing composition, curl activator gel, fragrant hair gloss, sun care products like sun stick and sun screen, soap, handwash, hand sanitizer gels, antibacterial hand cleaner, body scrub, hand scrub, bubble bath, bath oils, instant hand sanitizer, baby lotion, diaper rash cream, wet wipe, baby bath, and vitamin creams.

13. A personal care composition comprising 1,3-propanediol, wherein the 1,3-propanediol is biologically derived, wherein the composition is biodegradable and has a lower anthropogenic CO 2 emission profile as compared to a biodegradable composition comprising 1,3-propanediol with a bio-based carbon content of 0%, and wherein the 1,3-propanediol is a monomer, and comprises at least 3% biobased carbon.

14. The composition of claim 13 , further comprising an active.

15. The composition of claim 13 , further comprising a solvent.

16. The composition of claim 13 , further comprising a conditioning agent.

17. The composition of claim 13 , wherein the 1,3-propanediol has 100% biobased carbon.

18. The composition of claim 13 , wherein the personal care composition is a cosmetic.

19. The composition of claim 13 , wherein the personal care composition is selected from the group consisting of skin care composition, skin cleansing composition, make-up, facial lotion, cream moisturizer, body wash, body lotion, foot care products like foot cream, hand cream, lipstick, lip gloss, lip pencil, eyeshadow, gel eye color, eye liner, eye pencil, mascara, concealer, foundation, facial powder, liquid rouges, blush, deodorant, shaving cream composition, nail polish, gel polish removers, cuticle remover, cuticle cream, acne cream, acne cleansing scrub, toothpaste, shaving lotion, cream depilatory, lotion depilatory, wax depilatory, facial mask made with clay materials, anti-aging product, shampoo, hair care products like conditioner, hair treatment cream, styling gel, styling foam, hair mousse, hair spray, set lotion, blow-styling lotion, hair color lotion and dyes, hair bleaching cream hair relaxing composition, curl activator gel, fragrant hair gloss, sun care products like sun stick and sun screen, soap, handwash, hand sanitizer gels, antibacterial hand cleaner, body scrub, hand scrub, bubble bath, bath oils, instant hand sanitizer, baby lotion, diaper rash cream, wet wipe, baby bath, and vitamin creams.
