Compositions and methods for mitigating skin irritation
View Patent ↗The invention relates to a composition and a method for mitigating redness or inflammation of mammalian skin comprising administering to mammalian skin a composition consisting of an effective amount of alkanolamine, feverfew or soy or mixtures thereof, one or more optional benefit agents and one or more cosmetically acceptable carriers. More particularly, it relates to a composition for mitigating skin irritations such as retinol/retinoid irritation and their applications to mammalian skin.
1. A method for mitigating redness or inflammation of mammalian skin comprising topically applying to a mammal in need of treatment therefor a composition comprising:
(a) from about 1% to about 3% by weight of dimethylaminoethanol (DMAE) or a cosmetically-acceptable salt thereof;
(b) from about 0.2% to about 5% by weight of feverfew, and
(c) at least one acceptable carrier.
2. A method according to claim 1 , wherein said composition further comprises one or more effective amount of benefit agents to provide additional benefits for mammalian skins.
3. A method according to claim 2 , wherein said benefit agent is selected from the group consisting of emollients, skin conditioning agents, humectants, preservatives, antioxidants, perfumes, chelating agents, and mixtures thereof.
4. A method according to claim 2 , wherein said benefit agent is selected from the group consisting of benzocaine, hydrocortisone and mixtures thereof.
5. A method according to claim 2 , wherein said benefit agent is a skin-irritating benefit agent.
6. A method according to claim 5 , wherein said skin irritating benefit agent is selected from the group consisting of retinoid and retinoid derivatives, benzyol peroxide, alpha-hydroxy acids and derivatives thereof, anti-oxidants, salicylic acid, surfactants, natural plant extracts, sunscreen actives, urea, preservatives, and mixtures thereof.
7. A method according to claim 6 , wherein said retinoid derivatives are selected from the group consisting of vitamin A, retinyl palmitate, retinoic acid, retinal, and retinyl propionate, retinol, carotene, provitamin A, isotretinoin, accutane, arotinoid, adapalene, and tretinoin.
8. A method according to claim 7 , wherein said retinoid derivative is retinol.
9. A method according to claim 8 , wherein said retinol is present from about 0.01% to about 2% by weight.
10. A method according to claim 9 , wherein said retinol is present from about 0.1% to about 1% by weight.
11. A method according to claim 1 , wherein said carrier is in the form of cream, dressing, gel, lotion, ointment, liquid, or a spray applicator.
12. A method according to claim 1 , wherein said composition is applied to red or inflamed skin.
13. A method according to claim 12 , wherein said composition is applied to sunburned skin, wind-burned skin, or skin that is red or inflamed due to contact with irritating agents.
14. A method according to claim 12 , wherein said composition is applied to skin that is red or inflamed due to rosacea, atopic dermatitis, or allergic skin reactions.
15. A method for ameliorating the irritating effects of a composition containing a skin irritating benefit agent, said method comprising adding to said composition:
(a) from about 1% to about 3% by weight of dimethylaminoethanol (DMAE) or a cosmetically-acceptable salt thereof, and
(b) from about 0.2% to about 5% by weight of feverfew.
16. A method according to claim 15 , wherein said skin irritating benefit agent is selected from the group consisting of retinoid and retinoid derivatives, benzyol peroxide, alpha-hydroxy acids and derivatives thereof, anti-oxidants, salicylic acid, surfactants, natural plant extracts, sunscreen actives, urea, preservatives, and mixtures thereof.
17. A method according to claim 16 , wherein said retinoid derivatives are selected from the group consisting of vitamin A, retinyl palmitate, retinoic acid, retinal, and retinyl propionate, retinol, carotene, provitamin A, isotretinoin, accutane, arotinoid, adapalene, and tretinoin.
18. A method according to claim 17 , wherein said retinoid derivative is retinol.
19. A method according to claim 18 , wherein said retinol is present from about 0.01% to about 2% by weight.
20. A method according to claim 19 , wherein said retinol is present from about 0.1% to about 1% by weight.
21. A method according to claim 15 , wherein said composition is applied to red or inflamed skin.
