Abstract
Abstract Compositions obtained by reacting a tertiary amine having at least one long-chain group with a long-chain acid are disclosed. The compositions are useful in non-irritating skin or hair-contacting compositions, such as shaving creams, hair conditioners, skin conditioners, and aftershave. The compositions are also useful in non-irritating soap and dishwashing compositions. The compositions provide a combination of properties such as long-lasting slip, lubrication, emolliency, softening, and conditioning.
