Description
- This application is a divisional application of U.S. application Ser. No. 13/702,993 filed on Feb. 19, 2013, which is a 371 of International Application No. PCT/US2011/039366 filed on Jun. 7, 2011, which claims the benefit of U.S. Provisional Patent Application Nos. 61/352,146, 61/352,153 and 61/352,158, filed Jun. 7, 2010, the disclosures of which are hereby incorporated herein by reference.
- The present invention relates to methods and compositions of photoprotecting keratinous substrates using phenolic compounds and a compound chosen from at least one polyamine, at least one water soluble metal salt, or mixtures thereof.
- It is known that UV and visible radiations can damage keratinous substrates such as skin and hair and as a result, there are rising concerns among consumers and experts alike regarding the effects of these radiations on the human body. Cosmetic and personal care products aimed at protecting keratinous substrates, in particular the skin, from visible and ultraviolet light, are readily available, with particular emphasis on applying sunscreen to the skin before sun exposure. However, sun exposure of unprotected hair can also have deleterious effects on the hair, resulting in, for example, the degradation of the natural and artificial color of hair, dry and brittle hair, reduced strength of the hair fibers and an overall unhealthy appearance to the hair which is undesirable to the consumer.
- Photoprotective or sunscreen compositions currently available to consumers tend to easily be removed from the body upon contact with water. This can occur upon bathing in the ocean or in a swimming pool, in the shower or when engaged in water sports. Conventional photoprotective or sunscreen compositions do not continue to provide the desired photoprotection as soon as the keratinous substrate to which they have been applied comes in contact with water, thereby leaving the consumer unsatisfied with the efficacy of available photoprotective products. Thus, there is still a need to improve currently marketed anti-sun or sunscreen compositions which impart to the keratinous substrates effective photoprotection. There also continues to be a need for such compositions to be stable over time and resistant to water and that provide other desirable benefits such as more conditioned hair, less damaged hair and a better look and feel to the hair.
- Thus one of the objects of this invention is related to a composition and method that will provide desirable photoprotective benefits to keratinous substrates such as hair and minimize the deleterious effect of the sun on hair.
- It has been surprisingly and unexpectedly discovered that a composition containing the combination of a phenolic compound and a second compound chosen from at least one polyamine, at least one water soluble metal salt, or mixtures thereof imparts highly desirable cosmetic benefits such as less damaged hair, durability on the hair, shine on hair, improvements in the retention and enhancement of artificial or natural hair color, and hair fiber strength.
- Moreover, the use of this composition on keratinous substrates, such as hair and skin, can result in desirable and beneficial effects, such as improved conditioning and protection from environmental and chemical damage.
- The present invention is directed to a method of photoprotecting a keratinous substrate comprising applying a composition onto the keratinous substrate, the composition comprising:
-
- (a) at least one phenolic compound chosen from at least one ortho-diphenol, at least one phenolic compound having a carboxylic acid moiety, and mixtures thereof;
- (b) a compound chosen from at least one polyamine, at least one water soluble metal salt, and mixtures thereof;
- (c) a cosmetically acceptable carrier.
- The present invention is also directed to a photoprotective composition for application onto hair and skin, the composition comprising at least one phenolic compound chosen from at least one ortho-diphenol, at least one phenolic compound having a carboxylic acid moiety, and mixtures thereof; a compound chosen from at least one polyamine, at least one water soluble metal salt, and mixtures thereof; and a cosmetically acceptable carrier.
- Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term “about,” meaning within 10% to 15% of the indicated number.
- The term “comprising” (and its grammatical variations) as used herein is used in the inclusive sense of “having” or “including” and not in the exclusive sense of “consisting only of”. The terms “a” and “the” as used herein are understood to encompass the plural as well as the singular.
- “At least one” as used herein means one or more and thus includes individual components as well as mixtures/combinations.
- The term “water-soluble metal salt” as used herein is understood to mean any organic or inorganic metal salt having a solubility of more than 0.2 grams at 25 degrees Celsius per liter of water.
- The compositions and methods of the present invention can comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well as any additional or optional ingredients, components, or limitations described herein or any otherwise useful ingredient found in personal care compositions intended for application to keratinous materials.
- The present invention relates to a method for treating a keratinous substrate such as hair, the method involving the steps of providing a hair cosmetic composition containing at least one phenolic compound chosen from at least one ortho-diphenol, at least one phenolic compound having a carboxylic acid moiety, or mixtures thereof; A second compound chosen from at least one polyamine, at least one water soluble metal salt, or mixtures thereof; and a cosmetically acceptable carrier, and applying said composition onto the keratinous substrate.
- The present invention also relates to compositions for application onto hair and which may be utilized in leave-on conditioners, permanent waving compositions, hair coloring products, hair care products, hair treatment and hair masque products, and hair styling products. The compositions of the present invention may also be utilized in other personal care compositions such as body washes, skin care, sun care, nail care and facial care.
