Definitions

• This invention pertains to skin care compositions comprising an admixture of sucrose acetate isobutyrate and certain diol and glycerol carboxylate esters. More specifically, this invention pertains to liquid skin care compositions such as cosmetic, protective and therapeutic dermatological compositions comprising an admixture of sucrose acetate isobutyrate and one or more carboxylic acid esters of a polyol selected from propylene glycol and glycerol wherein the carboxylate ester residues contains from 2 to 10 carbon atoms.
• the skin care compositions exhibit smoothness and water resistance when applied to the skin such as the human body including eyelids and lips.
• SAIB Sucrose acetate isobutyrate
• SAIB is a stable liquid used as a weighting agent in citrus beverages such as fruit juices, energy drinks, and carbonated soft drinks. Weighting agents have a relatively high specific gravity and are mixed with the flavoring oils to stabilize the flavor emulsion and to prevent separation of the flavoring oils from the water in the finished beverage. SAIB (100%) has an extremely high viscosity at room temperature and must be heated to make it pourable before it can be added to the flavor ingredients.
• US Patent 4,705,691 discloses a beverage opacifier comprising (a) one or more substantially saturated fat as a clouding agent and (b) one or more weighting agent.
• Component (a) may be glyceryl tri-caprylate/caprate and component (b) may be SAIB.
• JP-B 1-52-35746 discloses a flavor composition for a beverage comprising (1) a flavor oil with (2) a C 8 -C 14 fatty acid ester of sorbitol, sorbitan or sorbide in an amount of 20-100% to the flavor oil, (3) SAIB and (4) a C 6 -C ⁇ 2 saturated fatty acid glyceride in an amount of 5-30% to the SAIB.
• JP-A1 -59-210870 discloses a sports drink composition consisting of 0.1-60 weight percent SAIB and 40- 99.9 weight percent of a food composition consisting of 0.01-10 parts by weight Vitamin E and 100 parts by weight of an oil-fat composition consisting of a mixed fat made of 30-95 weight percent of a medium-length triglyceride and 5-70 weight percent of a natural oil-fat or ester exchange oil and more than 80 parts by weight of less than 40 weight percent natural gum aqueous solution.
• SAIB (100%) is difficult to incorporate into cosmetic/personal care products because of its high viscosity and. because it is extremely tacky.
• Lipsticks and lip liners containing SAIB are proposed by JP-A1 -73-30549.
• a cosmetic composition comprising an oil, a dehydrated clay material and SAIB is disclosed in JP-A1- 61- 207314.
• SAIB must be heated to make it pourable for incorporation into cosmetics and skin care compositions.
• the high viscosity and, especially, the tackiness (stickiness) of SAIB severely limits its use in skin care products or as a skin care product by itself.
• WO 99/38489 discloses liquid personal cleaning emulsions containing a weighting oil that may be SAIB.
• compositions comprise 1-30% of a lipophilic skin moisturizing agent, 1-20% of a weighting oil, 0.1-5% stabilizer, 1-30% of a lathering agent and water.
• US Patents 5,747,058 and 6,413,536 disclose compositions for the delivery of biologically active substances comprising:
• a non-water soluble, high viscosity, liquid carrier material comprising a nonpolymeric ester or mixed ester of one or more carboxylic acids, having a viscosity of at least 5000 cP at 37°C, that does not crystallize neat under ambient or physiological conditions;
• Component (1) may be SAIB which may be diluted with an extensive variety of materials such as caprylic/capric triglyceride and propylene glycol dicaprylate/caprate to form a lower viscosity liquid carrier material.
• SAIB which may be diluted with an extensive variety of materials such as caprylic/capric triglyceride and propylene glycol dicaprylate/caprate to form a lower viscosity liquid carrier material.
• Example O of US 6,413,536 discloses a drug delivery composition comprising zidovudine and dideoxycytodine in a 70:30 SAIB/Miglycol® 810 mixture. Miglyol 810 is described elsewhere in the patent as a caprylic/capric triglyceride. If SAIB were easier to handle and had a smoother, less tacky feel on the skin, it could be used more widely in various types of cosmetics/personal care products.
