A patent granted for a cosmetic with specific ingredients
A recently granted patent (Publication Number: US11752076B2) discloses a new cosmetic formulation with specific ingredients and ratios. The cosmetic comprises three main ingredients: (A) a metal oxide with an average particle diameter of 0.01 µm to 0.1 µm, (B) an oil that is a paste at 25° C. and includes a hydrophilic group, and (C) an acrylates/ethylhexyl acrylate/dimethicone methacrylate copolymer.
The ingredient (B) can be glycerin fatty acid esters and/or dimer acid esters, and the mass content ratio of (B) to (C) should be between 0.5 and 1.5. The mass content ratio of (A) to (C) should be between 0.1 and 1. The ingredient (A) can be titanium oxide and/or zinc oxide.
Additionally, the patent claims that the cosmetic can be a water-in-oil cosmetic, which suggests that it has a higher oil content compared to water. The ingredient (B) can specifically be caprylic/capric/myristic/stearic triglyceride. In this case, the mass content ratio of (A) to (B) should be between 1.66 and 15.
This patent provides a specific formulation for a cosmetic product, focusing on the particle size of the metal oxide, the type of oil used, and the copolymer ingredient. By using these specific ingredients and ratios, the cosmetic aims to achieve desired properties and performance.
It is important to note that the patent does not provide information on the specific application or intended use of the cosmetic. However, the inclusion of metal oxides, such as titanium oxide and zinc oxide, suggests that the cosmetic may have sun protection properties. The use of a water-in-oil formulation indicates that the product may have a more moisturizing and emollient texture.
Overall, this granted patent introduces a novel cosmetic formulation with specific ingredient combinations and ratios. The disclosed formulation may have potential applications in the cosmetics industry, particularly in products that require sun protection and moisturizing properties.
