Abstract
Description
[Technical Field]
[0001] The present invention relates to gel compositions containing NIPU elastomers prepared by the reaction of polycyclic or poly-non-cyclic carbonates with polyamines, optionally utilizing a catalyst to enhance the rate of elastomer formation, preferably contained in a topically acceptable carrier fluid to form a gel. The gel compositions may also contain personal or healthcare active ingredients. The active ingredients may be incorporated into the gel by either pre-dosing or post-dosing methods. The gel compositions may further be used as components of personal care compositions. [Background technology]
[0002] Silicone elastomers are widely used in personal care applications due to their thickening and gelling properties and unique silky, powdery sensory characteristics. While silicone elastomers are compatible with silicone-based fluids, silicone-based fluids for topical use are gradually disappearing from the personal care industry due to health and environmental concerns. There is a need to develop alternatives to silicone elastomers that exhibit efficient thickening and gelling capabilities with non-silicone-based, topically acceptable solvents (e.g., esters, triglycerides, and alkanes) and impart a silky, powdery skin feel comparable to that of silicone elastomers. Polyurethane elastomers fulfill this need and may be a desirable alternative to silicone elastomers. Non-isocyanate polyurethane (NIPU) elastomers offer an environmentally friendly alternative to isocyanate-derived polyurethanes, which require starting materials synthesized from toxic precursors.

[0043] The amount of component (E) present in the NIPU gel composition can vary, but is typically in the following range: 0.05 to 50 weight percent, alternatively 1 to 25 weight percent, or alternatively 1 to 10 weight percent, based on the weight of the NIPU elastomer present in the composition, i.e., the total weight of components (A), (B), (C), and (D) in the NIPU gel composition.
[0044] The active ingredient (E) may be added to the NIPU gel composition during the manufacture of the NIPU elastomer (pre-dosing method) or may be added after the formation of the NIPU elastomer gel (post-dosing method).
[0045] The pre-injection method is I) The following A) cyclic or aliphatic carbonate polymers (which may optionally contain siloxane in their backbones); B) Aliphatic or cycloaliphatic polyamines; C) optionally a reaction catalyst; D) optionally a carrier fluid, wherein the locally acceptable carrier fluid is a reaction solvent or the carrier fluid is added after elastomer formation, optionally the carrier fluid comprises a locally acceptable carrier fluid; E) personal care or healthcare active ingredients together with NIPU elastomer gel; to form an active ingredient-containing NIPU elastomer gel.

The personal care active ingredient may be mixed as a component of a separate mixture with one or more excipients.
[0047] NIPU elastomer The NIPU elastomers of the present invention can be obtained as the NIPU reaction product of components (A), (B), and (C) in (D). The term "NIPU reaction" refers to the addition of a compound containing multiple cyclic or acyclic carbonate groups (e.g., component A) to a compound containing multiple primary or secondary amine groups (e.g., component B), optionally in the presence of a catalyst (e.g., component C). Here, the molar ratio of carbonate to amine groups is 1 / 1. Alternatively, this ratio can range from 8 / 1 to 0.9 / 1. The NIPU reaction is carried out in the presence of a solvent, which is the same as the carrier fluid described as component (D), and can optionally be used without further purification.
[0048] Method for measuring the hardness of NIPU elastomer gel compositions The NIPU elastomer is prepared in a carrier fluid (described above as component D) to form a gelled composition. The gelled compositions of the present invention can be characterized by their hardness or firmness. Useful tests for characterizing gels are those recommended by the Gelatin Manufacturers Institute of America, such as the use of a "Texture Analyzer" (Model TAXT2, Stable Micro Systems, Inc., Godalming, UK). Gel samples are subjected to a compression test using a texture analyzer equipped with a probe with a 5.0 kg load cell. The probe approaches the surface of the gel at a rate of 1 mm / sec and continues to compress the gel for a distance of 5.0 mm. The texture analyzer detects the resistance force experienced by the probe during the compression test. The load cell force is plotted as a function of time. For purposes of this invention, the hardness of NIPU elastomers, gels, and elastomer blends (SEBs) is defined as the resistance force detected by the "Texture Analyzer" probe during the compression test. Hardness is characterized as the force at the point of maximum compression (i.e., 5.0 mm compression into the gel surface). Each gel was typically tested an average of three times, and gels were prepared in triplicate.
[0049] The resulting force (grams) value is converted to Newtons (N) by dividing by 101.97 (i.e., 1 Newton equals 101.97 grams force, based on the size of the probe used). The second property reported from a Texture Analyzer measurement is Area FT 1:2 (gram force·seconds), which is the area integral of the force-test time curve. This property, associated with elastomers and gels, indicates the ability to maintain resistance to compressive forces and is therefore indicative of the gel network. Values are reported in grams force·seconds (g force.sec) and are converted to the SI unit of Newton seconds (Newton.sec) by dividing the force.sec value by 101.97.
[0050] The NIPU gel of the present invention has a resistance of at least 0.5 Newtons / cm when measured with a 1.27 cm diameter spherical probe and a 50 g sample of the gel placed in a 4 oz round glass jar. 2 , or 1 Newton / cm 2 , or alternatively 2 Newtons / cm 2 It has a compressive hardness of .
[0051] NIPU elastomer-containing gel paste composition Using the gelling composition of the present invention, I) shearing the NIPU elastomer gel as described below; II) Add the sheared NIPU elastomer gel to an additional amount of D) a carrier fluid as described above, and optionally E) mixing with a personal care or health care active ingredient to form a gel paste or blend composition; A gel paste or gel blend composition containing the active ingredient can be prepared by the process described above. The personal care active ingredient may also be mixed as a component of a separate mixture with one or more excipients.
[0052] The NIPU elastomer gel compositions of the present invention can be viewed as discrete crosslinked NIPU elastomer gel particles dispersed in a carrier fluid. As such, the NIPU elastomer compositions are effective rheological thickeners for compatible low molecular weight solvents. As such, they can be used to prepare useful gel blend compositions, such as "gel paste" compositions.
[0053] To produce such NIPU elastomer gel pastes, the NIPU elastomer gel of a known initial elastomer content (IEC) is sheared to obtain a reduced particle size and then further diluted to a final elastomer content (FEC). As used herein, shearing refers to any shear mixing process, such as homogenization, sonolating, or other mixing processes known in the art as shear mixing. Shear mixing of the NIPU elastomer gel composition results in a composition with reduced particle size. The composition with reduced particle size is then further mixed with D) a carrier fluid. The carrier fluid can be any carrier fluid as described above, but is typically a linear ester (e.g., heptyl undecylenate), a triglyceride (e.g., triheptanoin), or an alkane (e.g., isododecane). The technique for combining the D) carrier fluid with the NIPU elastomer composition with reduced particle size is not critical and typically involves simple stirring or mixing. The resulting composition can be considered a paste, having a viscosity greater than 100,000 cP (mPas).
[0054] Method for measuring viscosity of NIPU elastomer gel paste When used with a suitable Brookfield viscometer equipped with a special T-bar spindle, the Brookfield HELIPATH™ stand allows viscosity / consistency measurements in centipoise for materials with properties similar to pastes, putties, creams, gelatin, or wax. The viscosity of the NIPU elastomer blend was determined using a Brookfield Model DV-II+ Pro viscometer equipped with a HELIPATH™ stand (Brookfield Model D) and a T-bar spindle (Brookfield HELIPATH™ spindle set). All were purchased from Brookfield Engineering Laboratories, Inc. (11 Commerce Boulevard, Middleboro, Mass., USA). A sample size of 50 g in a 4-ounce round jar was required. Prior to measurement, the following preparation procedure was used: air bubbles were first removed from the sample by centrifugation, followed by 2 hours under vacuum. After degassing, the sample was conditioned at 25°C for a minimum of 4 hours. Measurements were performed according to the typical procedure for the HELIPATH™ spindle. Typically, spindle 93 (T-bar spindle E) was used, with a standard setting of 6.5 rpm. The spindle speed was kept constant at 6.5 rpm.

In such formulations, the gel compositions or gel pastes are preferably used as thickeners or stabilizers for the topical formulations. Other components of topical formulations are known in the art and may include, for example, various ingredients such as emulsion stabilizers, emulsifiers, skin conditioners, suspending agents, etc. The amount of these additional ingredients may be on the order of about 0.01% to about 50% by weight.

To a 4 oz. glass jar was added dilinoldiol dimethyl dicarbonate (25.0 g) (previously synthesized by the reaction of dilinoldiol with dimethyl carbonate) and Jeffamine T-403 (12.65 g; Huntsman International LLC, The Woodlands, TX). The reaction mixture was stirred at room temperature until homogeneous, at which point triazabicyclodecene (753 mg) was added. The clear, colorless reaction mixture was heated to 120°C overnight to yield a slightly colored, clear, non-pourable elastomeric rubber. The hardness of this elastomeric rubber, measured using a Stable Micro Systems Texture Analyzer (equipped with a 5 kg load cell and fitted with a TA-18B Stable Micro Systems probe inserted 5 mm into the gel surface), was 180 N / cm. 2 It was.
[0106] Example 11 - Preparation of Castor Oil / Isophorone Diamine NIPU Elastomer To a test tube was added castor oil carbonate (500 mg), previously synthesized by the reaction of castor oil with dimethyl carbonate, and isophoronediamine (247 mg). The reaction mixture was vortexed at room temperature until homogeneous, at which point triazabicyclodecene (12.47 mg) was added. The reaction mixture was heated to 120°C in a heat block and vortexed to ensure a homogeneous mixture. The reaction mixture was heated at 120°C overnight, resulting in a slightly non-flowable elastomeric rubber. The hardness of this elastomeric rubber, measured using a Stable Micro Systems Texture Analyzer (equipped with a 5 kg load cell and fitted with a TA-18B Stable Micro Systems probe inserted 5 mm into the gel surface), was 250 N / cm. 2 It was.
[0107] Example 12 - Preparation of Dilinol Diol / Polyoxypropylene Triamine NIPU Elastomer Gel Paste The dilinol diol / polyoxypropylene triamine NIPU elastomer of Example 10 was crushed into small pieces using hand tools, and 24.65 g of the elastomer solids were added to a stainless steel reaction vessel, followed by 24.65 g of diisooctyl succinate. The slurry was mixed for 5 minutes using a Silverson L5M-A homogenizer (with a 30 mm diameter rotor and a square-hole high-shear screen) operating at 5,000 rpm and then homogenized to obtain a smooth gel paste. The viscosity of the resulting smooth gel was measured to be 62,333 cps using a Brookfield Model D Helipath stand and a Brookfield Model DV-II+Pro Viscometer with a TC spindle. Measurements were performed according to the typical procedure for the Helipath spindle, with a constant spindle speed maintained at 6.5 rpm and a torque of 37.4%.
