The invention relates to a cosmetic active ingredient comprising at least one extract of Avena strigosa and at least one extract of Ononis spinosa.

The invention also relates to a composition including it, a method for obtaining it and the use of this cosmetic active ingredient, in particular for its anti-graying effect on the hair.

Disclosed is a hair care composition comprising from about 0.04 wt % to about 2 wt % azelaic acid; from about 0.04 wt % to about 1 wt % oleic acid; wherein the ratio of oleic acid to azelaic acid is from about 1:1 to about 1:3, alternatively from about 1:2.5 to about 1:3 oleic acid to azelaic acid, alternatively from about 1:2 to about 1:3 oleic acid to azelaic acid, alternatively from about 1:1.5 to about 1:3 oleic acid to azelaic acid; and an aqueous carrier. The hair care composition may further include silicones. Additionally, the hair care composition can comprise from about 0.1 wt % to about 10 wt % of a cationic surfactant system. The hair care composition may also comprise from about from about 1% to about 15% of a high melting point fatty compound. The hair care composition provides an increased strength benefit. This hair strength benefit can be delivered to the consumer through a variety of hair care products including but not limited to conditioners, leave on treatments, and rinse off products.

A cream to be applied topically to the hair and scalp in order to infuse moisture. The present invention effectuates this capability through a mixture of a raw material blend, in a chemical composition’ proportion that brings about effective results. The prevailing ingredients in the finished product are pumpkin seed oil (Cucurbita pepo), rosehip seed oil (Rosa canina L.), mango butter (Mangifera indica), and citric acid.

The present disclosure relates to hair treatment compositions comprising at least one amino acid, at least one carboxylic acid, and monoethanolamine. The disclosure also relates to methods of using the hair treatment compositions.

PROBLEM: To provide a cosmetic composition that has a moisturizing effect that gives lasting moisture to a skin, an effect that prevents or improves aging symptoms, such as wrinkles and sags, and similar effect.

SOLUTION: Nicotinamide mononucleotide is contained in a cosmetic composition.

The invention relates to a method for obtaining an aqueous extract of Anethum graveolens, enriched with small RNAs having a maximum length of 150 nucleotides, from a plant material, said method comprising the following steps: a) aerial parts of dill is brought into contact with water; b) tetrasodium ethylenediaminetetraacetic acid (EDTA) is added at a pH of between 10.5 and 11; c) the pH of the mixture obtained in b) is then adjusted to a value of between 6 and 8; d) the mixture obtained in c) is purified; and e) the pH is checked and readjusted if necessary to a value of between 6 and 8. The invention also relates to an aqueous extract of Anethum graveolens, enriched with small RNAs having a maximum length of 150 nucleotides, obtained by the method.

A composition and a process for modifying hair are disclosed. The process includes coating hair fibers with a composition comprising propylene carbonate and a glycol selected from at least one of propylene glycol, 1,3-propane diol, dipropylene glycol, tripropylene glycol, and mixtures thereof and contacting the coated hair with a heating appliance at a temperature of at least 150° C. for a sufficient time to modify the hair fibers.
