  • the invention relates to cosmetic production and can be used to create hydrogen-saturated cosmetic compositions containing water, surfactants, and other cosmetic ingredients.
  • Such compositions may be used as detergents and other cosmetics such as foams, gels, shaving creams, liquid soaps, shampoos and other hair and body washes and care products.
  • Antioxidant activity is an important characteristic of the quality and value of cosmetic compositions.
  • An increase in the antioxidant activity of the compositions leads to an increase in their reducing properties and the ability to react with reactive oxygen species and radicals attacking cell membranes, tissue proteins, enzymes and DNA.
  • Numerous studies have shown that hydrogen has anti-inflammatory, antitumor effects, and can prevent radiation and ultraviolet damage to the skin. With this in mind, the consumption of hydrogen-saturated drinking water is expanding, and more and more hydrogen-enriched cosmetics, called “hydrogen cosmetics", are appearing. Hydrogen water, hydrogen masks, hydrogen creams and other products are known on the market. Below are a number of patented technical solutions related to cosmetic compositions saturated with hydrogen, including those containing surfactants.

  • the antioxidant is added in a minimal amount so as not to change the organoleptic properties of water, which is important for the resulting drink.
  • the composition has increased antioxidant activity (redox potential from minus 600 to minus 50 mV), and the authors state that the product can be used directly as a drink or can be used in the production of soft drinks and cosmetics with increased antioxidant activity.
  • This aqueous hydrogen cocktail was obtained by a traditional method similar to the production of hydrogen water. Pure water with an antioxidant dissolved in it is bottled into standard polyethylene terephthalate (PET) bottles with a volume of 0.5 to 2 liters, saturated in them with hydrogen under pressure using a device for carbonation and liquid capping.

  • its use as a propellant is very difficult and practically does not occur, which explains the extremely rare (unknown to us) use of hydrogen as a propellant in aerosol cans.

  • the authors propose a special composition in the form of a tablet, which contains metallic magnesium, a water-soluble acid and a binder, the composition may also include a lubricant.
  • the tablet releases hydrogen when in contact with water, which makes it possible to prepare highly saturated hydrogen water shortly before its use, and thus maintain hydrogen saturation for the consumer.
  • the tablet is proposed to be placed in water, which water may also contain other ingredients such as fruit juice, carbonated water or dissolved solids such as table sugar or salt.

  • the technical result of the claimed invention is to increase the hydrogen concentration in the cosmetic composition and maintain the hydrogen concentration during storage of cosmetic products, as well as at the stage of its use by the consumer.
  • the proposed solution is based on the fact that not the source water is subjected to hydrogen saturation, but the final cosmetic composition, placing it in a sealed vessel under pressure of a mixture consisting of at least two components, one of which is hydrogen, the second is light room temperature liquefiable propellant such as isopentane, isobutane, and the like.
  • This combination makes it possible to increase the concentration of hydrogen in the composition, preserve hydrogen during storage and use, and reduce the pressure of the propellant when packaged in aerosol cans.

Since the typical time between product packaging and sale is much longer than a day, the step of hydrogenating the cosmetic composition in an aerosol can will not cause any negative commercial consequences.
