Compositions comprising organo-silanol compounds, and applications

A hydroglycolic solution comprising:

• a) a first organo-silanol of the following general formula (I):
• X—Si(OH)3 (I)
• wherein X is a linear or branched C1-C4 alkyl group, optionally substituted with at least one hydroxyl group;
• b) a second organo-silanol of the following formula (III):
• X—Si(OH)2O—CH(R1)—CH(R2)(R3) (III)
• wherein:
• the X is a linear or branched C1-C4 alkyl group optionally substituted with at least one hydroxyl group;
• R1 is —H or —CH3;
• R2 is —H, —OH, or —CH3;
• R3 is —CH3, —CH2—CH3, —CH2OH, —CH(CH3)OH, —CH2—CH2—CH3, —CH2—CH2—CH2—CH3, —CH2—CH2—CH2—CH2—OH, or —C(CH3)(CH3)—OH;
• c) an organo-silanol(s) stabilising agent, suitable for allowing the formation of a molecular complex with said first and second organo-silanols via the establishment of at least one hydrogen bond with said first and second organo-silanols, wherein said organo-silanol(s) stabilising agent is selected from adenosine, glycyrrhizic acid and/or its salts, glycyrrhizin and/or its salts, lactobionic acid and/or its salts, alginic acid and/or its salts, hyaluronic acid and/or its salts, lactose, trehalose, 6-deoxy-L-mannopyranose and/or its salts, theophylline acetic acid, ascorbic acid, lactic acid, salicylic acid and/or its salts, pyrrolidone carboxylic acid and/or its salts, arginine and/or its salts, serine and/or its salts, lysine and/or its salts, methionine and/or its salts, acetyl methionine and/or its salts, threonine and/or its salts, hydroxyproline and/or its salts, N-acetyl tyrosine and/or its salts, aspartic acid and/or its salts, glutamic acid and/or its salts, oleic alcohol, panthenol, caffeine, pectin, acefylline, chondroitin sulfate, hydrolysed pearl, a protein hydrolysate of animal or plant origin, and mixtures thereof;
• and
• d) at least one glycolic solvent,
• wherein the water/glycolic solvent mass ratio is between 80/20 and 50/50.
