Durable styling compositions and the uses thereof

Abstract

Compositions are disclosed that impart one or more durable hair styling benefits. The durable styling compositions comprise at least a first compound having anhydride, diacid, diester, or half-acid / half-ester functionality, and a second compound having at least one amine moiety or hydroxyl functional group. In one embodiment the durable styling composition takes the form of a leave-in product. The durable styling compositions are heat-activated, which may be accomplished through the use of a heated styling tool like a flat-iron, curling iron, and / or hair dryer. The benefits include shine, conditioning, softness, defrizzing, and improved hair alignment, and endure for up to 5 wash cycles or more without having to reapply the durable styling composition nor heat.

Description

FIELD OF THE INVENTION[0001]The invention relates to compositions for hair care, and more specifically, to compositions that impart a durable hair styles that last for up to 5 wash cycles or more.BACKGROUND OF THE INVENTION[0002]Many people express interest in hair styling benefits like shine, softness, and manageability, especially for wavy, curly, or frizzy hair. Typically, these benefits are attained using hair care products like rinse-off shampoos and conditioners, and leave-in products that are not washed off like gels and mousses. Likewise, people with straight hair often curl their hair to change their hair style and appearance. Curling irons and hair curlers can provide curls and / or waves, which are then held in place using hair spray. In both scenarios, however, the results are often short-lived as the hair styling benefits are not durable, but rather are lost after washing. Other styling products, like permanent wave and high-pH hair straightening formulas, achieve a perma...

AI Technical Summary

Benefits of technology

The patent describes a hair styling product that can be applied to hair and then heated with a tool to create durable styles that last for up to five washes. The product can provide benefits such as softness, defrizzing, curling, shine enhancement, better hair alignment, and manageability. The key ingredient is a composition that is activated by heat and forms a stable bond with the hair, allowing for a long-lasting, maintenance-free style.

Problems solved by technology

In both scenarios, however, the results are often short-lived as the hair styling benefits are not durable, but rather are lost after washing.

Due to the chemical processes involved, these “permanent” products may achieve long-enduring style at the cost of considerable damage to the hair.

Additionally, consumers may find the results last too long, and therefore do not enjoy the option of being able to undo the style without cutting off the hair or risking further chemical modification of the hair.
