According to GlobalData’s company profile on Mary Kay, nanoemulsion cosmetics was a key innovation area identified from patents. Mary Kay's grant share as of September 2023 was 56%. Grant share is based on the ratio of number of grants to total number of patents.

A recently granted patent (Publication Number: US11771638B2) discloses a non-aqueous composition for treating skin conditions. The composition includes ascorbic acid, a silicone oil, at least 15% by weight of an essential oil, propylene glycol, and glycerin. The composition may contain at least 10% by weight of ascorbic acid and may include dimethicone and polysilicone-11 as the silicone oil. Additionally, hyaluronic acid may be included in the composition. The essential oil may consist of orange oil and lemon oil. The ascorbic acid in the composition may comprise L-ascorbic acid and ascorbyl glucoside.

Importantly, the composition does not contain a non-volatile oil and is not an emulsion. It also does not include an emulsifier or a surfactant. The stability of the ascorbic acid in the composition is noteworthy, with at least 75% of the initial amount remaining stable after being stored for at least 1 month at room temperature. In some embodiments, at least 90% of the initial amount of ascorbic acid remains stable under the same conditions.

The composition may contain 25 wt. % to 50 wt. % of the essential oil, and at least 25 wt. % of the essential oil in some cases. The silicone-containing compound in the composition is less than 50 wt. %. The vitamin C (ascorbic acid) in the composition can be either suspended or solubilized.

The composition can be used as a topical skin formulation or as a pharmaceutical composition. It offers a method of treating skin conditions by topically applying the composition to the affected skin. This method is particularly effective for treating fine lines and wrinkles, where the composition is applied directly to the affected areas.

In summary, this granted patent discloses a non-aqueous composition containing ascorbic acid, silicone oil, essential oil, propylene glycol, and glycerin for treating skin conditions. The composition is stable and does not require the use of non-volatile oils, emulsifiers, or surfactants. It can be used as a topical skin formulation or a pharmaceutical composition, providing an effective method for treating fine lines and wrinkles.
