More specifically, the present invention relates to hair conditioning compositions comprising a high molecular weight ester oil, a hydrophilically substituted cationic surfactant, and a high melting point compound.
• shampooing cleans the hair by removing excess soil and sebum.
• shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless, or friaZzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components.
• the hair can further be left with increased levels of static upon drying which can interfere with combing and result in a condition commonly referred to as "fly-away hair", or contribute to an undesirable phenomena of "split ends", particularly for long hair.
• hair conditioning agents such cationic surfactants and polymers, silicone conditioning agents, hydrocarbon oils, and fatty alcohols.
• Cationic surfactants and polymers, hydrocarbon oils and fatty alcohols are known to enhance hair shine and provide moistness, softness, and static control to the hair.
• such components can also provide stickiness or greasy or waxy feeling, particularly when the hair is dried.
• Silicone conditioning agents are also known to provide conditioning benefits such as smoothness and combing ease due to the low surface tension of silicone compounds.
