Personal care and cosmetic compositions comprising renewably-based, biodegradable 1,3-propanediol

Abstract

Disclosed herein are methods of reducing irritation associated with personal care and cosmetic compositions comprising 1,3-propanediol, wherein the 1,3-propanediol in said personal care or cosmetic composition has a bio-based carbon content of about 1% to 100%. In addition, it is preferred that the 1,3-propanediol be biologically-derived, and wherein upon biodegradation, the biologically-derived 1,3-propanediol contributes no anthropogenic carbon dioxide emissions to the atmosphere.

We claim: 
     
         1 . A method of reducing irritation associated with a personal care composition, the method comprising the step of:
 preparing a biodegradable personal care composition comprising 1,3-propanediol and an acceptable carrier, wherein said 1,3-propanediol has a bio-based carbon content of at least 1%, a peroxide concentration of less than about 10 ppm, a concentration of total organic impurities of less than about 400 ppm, and a “b” color value of less than about 0.15 and an absorbance at 275 nm of less than about 0.050;   wherein the personal care composition reduces irritation compared to a personal care composition comprising chemically synthesized 1,3-propanediol and other glycols.

         3 . The method of  claim 1 , wherein the personal care composition further comprises a solvent. 
     
     
         4 . The method of  claim 1 , wherein the 1,3-propanediol has at least 99% bio-based carbon. 
     
     
         5 . The method of  claim 1 , wherein the 1,3-propanediol has at least 100% bio-based carbon. 
     
     
         6 . The method of  claim 1 , wherein the 1,3-propanediol is biologically-derived. 
     
     
         7 . The method of  claim 1 , wherein the biologically-derived 1,3-propanediol is biologically produced through a fermentation process. 
     
     
         8 . The method of  claim 1 , wherein the 1,3-propanediol has a concentration of total organic impurities of less than about 300 ppm. 
     
     
         9 . The method of  claim 1 , wherein the 1,3-propanediol has a concentration of total organic impurities of less than about 150 ppm. 
     
     
         10 . The method of  claim 1 , wherein the personal care composition is selected from the group consisting of a lipstick, lip gloss, lip pencil, eye shadows, foundation, blush, liquid rouge, facial powder, make-up, concealer, gel eye color, mascara, lip gloss, eye pencil, lip pencil, eye make-up remover, eye liners, eye shadow, lotion eye color, gel eye color, nail polish, lipstick nail polish, gel polish removers, liquid rouges, blush, and facial powder, skin care composition, skin cleansing composition, skin cleansing bar, skin cleansing liquid, facial lotion, facial cream, cream moisturizer, body wash, body lotion; foot cream, hand cream; deodorant and antiperspirant sticks, roll-ons, aerosols, gels, creams, pump sprays, powders, odor-masking, odor-neutralizing, odor-quenching, odor-inhibiting; cologne sticks, perfumes, shaving cream, shaving lotion, cream depilatory, lotion depilatory, wax depilatory, facial mask made with clay materials, anti-aging product, anti-wrinkle product, anti-cellulite product, cuticle remover, cuticle cream, acne cream, acne cleansing scrub; toothpaste, gargle, mouth wash, mouth rinse, film, gum; shampoo, hair conditioner, hair treatment cream, styling gel, styling foam, hair mousse, hair spray, set lotion, blow-styling lotion, hair color lotion, creams and dyes, hair bleaching cream, hair relaxer, hair straightener, curl activator gel, fragrant hair gloss, bleach, sun stick and sun screen, artificial tanning products, skin-whitening products; soaps, hand wash, body scrub, hand scrub, bubble bath, bath oils, instant hand sanitizer, hand sanitizer gels, antibacterial hand cleaner, deodorants, anti-perspirants, baby lotion, diaper rash cream, wet wipe, and baby bath, and vitamin creams. 
     
     
         11 . The method of  claim 1 , wherein the personal care composition has a pH between about 4 and 9. 
     
     
         12 . The method of  claim 1 , wherein the personal care composition has a pH of about 7. 
     
     
         13 . A method of reducing the atmospheric CO 2  emission of a personal care composition upon degradation, the method comprising:
 preparing a biodegradable personal care composition comprising 1,3-propanediol and an acceptable carrier, wherein said 1,3-propanediol is biologically derived, biodegradable and exhibits no atmospheric CO 2  emission upon biodegradation; and   using said personal care composition whereby said personal care composition biodegrades, wherein said reduction of atmospheric CO 2  emission is compared to the atmospheric CO 2  emission of a personal care composition not comprising 1,3-propanediol that is biologically derived and biodegradable.   
     
     
         14 . The method of  claim 13 , wherein the personal care composition further comprises an active.
