CROSS REFERENCE TO RELATED APPLICATIONS

This application is a 35 U.S.C. § 371 U.S. national phase entry of International Application No. PCT/US2019/066928 having an international filing date of Jun. 26, 2019, which claims the benefit of European Application No. 18181832.9 filed Jul. 5, 2018, both of which are incorporated herein by reference in its entirety.

FIELD

The invention relates to compositions comprisingA) at least one hybrid quat andB) at least one fatty alcohol.

BACKGROUND

Alkyl quats and ester quats are used in cosmetic formulations as hair conditioning agents. Both have certain disadvantages: alkyl quats, especially dialkyl quats, are generally poorly biodegradable and contaminate the environment. Ester quats, especially TEA ester quats, are sensitive to hydrolysis and therefore can only be used in aqueous formulations to a limited extent.

It could now be shown that alkyl ester quats (hybrid quats), consisting of an ammonium salt having at least one fatty alkyl chain and at least one ester group esterified with fatty acid, have excellent conditioning properties and at the same time do not have the disadvantages of the alkyl quats or ester quats.

Surprisingly, it has also been found in addition that the alkyl ester quats are capable of creating exceptionally high viscosities in formulations with fatty alcohol.

DE3623215 discloses cosmetic hair compositions comprising highly ethoxylated hybrid quats and fatty alcohol.

DE2928603 discloses hybrid quats and use thereof as laundry fabric softeners.

The object of the invention was to provide alternative hair conditioning agents based on quaternized ammonium compounds.

SUMMARY

It has been found that, surprisingly, the hybrid quats described below are able to solve the problem addressed by the invention.

The present invention therefore relates to compositions comprising certain hybrid quats and fatty alcohol.
