摘要:
Coated particles of metal (such as calcium) silicate that exhibit excellent odor neutralization and sebum absorption properties when present within certain cosmetic and/or personal care formulations and suspensions are provided. Uncoated calcium silicate exhibits a high pH level that may have a deleterious effect upon such cosmetic and/or personal care compositions, thereby rendering the overall composition ineffective for its intended purpose, particularly if the calcium silicate is present in its usual state at high loading levels. Alternatively, if certain materials present within personal care compositions exhibit a sufficiently low pH level, the effectiveness of such calcium silicates may be compromised as well. Such novel coated/treated calcium silicates thus permit high loadings of this beneficial odor neutralizing/sebum absorbing additive within cosmetic and/or personal care formulations without causing any appreciable instability issues or viscosity modification concerns or allow for coexistence with such low pH materials without any appreciable reduction in performance capabilities of the calcium silicates themselves. Certain personal care compositions comprising these novel coated calcium silicate particulates are encompassed within this invention as well.

摘要:
The aluminum and hexamethylenetetramine (Al-HMT) complex is obtained by mixing a source of aluminum and HMT and optionally leaving the resulting mixture to sit. The Al-HMT complex has deodorant and therapeutic properties, and it is useful for elaborating cosmetic and pharmaceutical compositions. Furthermore, said Al-HMT complex has the capacity to trap substances which can subsequently be released, it therefore being useful as a carrier of said substances.
摘要:
A method is provided for determining crystallization conditions for a protein, the method comprising: performing in a same fermentation apparatus 2 or more separate fermentations where each fermentation comprises cells expressing a protein to be purified and has a fermentation volume of less than 500 mL; purifying the expressed protein from the separate fermentations; and determining crystallization conditions for the purified protein by submicroliter crystallization experiments.
摘要:
The present disclosure relates to a deodorant cosmetic composition comprising: a) zinc pidolate and b) at least one antiperspirant aluminum salt, wherein the zinc pidolate/at least one aluminum salt weight ratio ranges from 1/200 to 10/1. The present disclosure also relates to a cosmetic process for treating human perspiration and human underarm odors with the composition disclosed herein.
摘要:
Disclosed are basic aluminum halides having enhanced antiperspirant efficacy; methods of making such materials and antiperspirant compositions containing such basic aluminum halides, and optionally an amino acid, salts of amino acids, antimicrobial agents, or an organic solvent having at least two carbon atoms and at least one hydroxy group and mixture thereof and methods of making such mixtures. Basic aluminum halides having enhanced antiperspirant efficacy are produced by reacting (a) aluminum powder; (b) an aluminum halide; and (c) water at a temperature greater than about 85° C. This reaction is maintained until reaction products having an Al:halide ratio of about 1.2:1 to 1.5:1 and preferably 1.3 to 1.4:1; and a solution solids concentration of about 30-40 weight percent on an anhydrous basis are obtained. The products are characterized as having a Size Exclusion Chromatography (HPLC) Test Band I of less than 5%, preferably less than 1%, Band II percent aluminum value of 20-60% preferably about 35 to 55%, Band III percent aluminum value of 10 to 35% preferably 15-30% and Band IV value of 15 to 50% and preferably 25 to 35% and sum of peak 3 and 4 areas of at least 45% and no more than 70% and preferably 65%. The enhanced efficacy basic aluminum chloride salts of this invention are more economical to produce, show enhanced efficacy and are more stable compared to the conventional enhanced efficacy aluminum salts which show rapid degradation of Band III to Band II peak areas ratio are less irritant and more skin friendly.
摘要:
A water-free antiperspirant composition is presented which comprises a) at least two particulate polysaccharides and/or polysaccharide derivatives, b) at least one astringent antiperspirant agent and c) at least one lipid component with a melting point of 30 to 150° C. in a liquid carrier material.
摘要:
A deodorant composition in the form of a water-in-oil emulsion comprising an effective amount of at least one alum salt dissolved in the aqueous phase of the said emulsion. A process for treating human underarm odors using the present deodorant composition.
摘要:
A suspension antiperspirant composition for topical application to the human skin comprising from 10 to 26% by weight of the composition of a solid particulate antiperspirant active suspended in a cosmetic base, wherein the antiperspirant active comprises a blend of an antiperspirant active with relatively small particles with a volume average particle size in the range of from 0.5 to 8 .mu.m and of an antiperspirant active with relatively large particles having a volume average particle size in the range of larger than 12 to smaller than 50 .mu.m, the weight ratio of the antiperspirant active having smaller particles to the antiperspirant active having larger particles in the composition is in the region of 5:1 to 1:5 by weight.
