Abstract: A cleansing composition based on oily substances, particularly for cleansing skin and/or hair and having excellent dermatological properties, is described. The composition is characterized in that it comprises one or more oily substances at a total concentration of between 10% and 90% by weight relative to the composition and one or more surfactants selected from the N-acylates of amino-acids, proteins, and peptides, in acid or neutralized form, at a total concentration within the range of between 2% and 80% by weight relative to the composition, and in that it is substantially anhydrous or has a water content no greater than 10% by weight.

Abstract: The invention relates to a concentrated base, particularly for detergent products and products for personal care and hygiene, comprising a combination of at least three surfactants selected from the group consisting of acylmethyltaurates, alkylamidopropylbetaines, alkyl amphoacetates, alkyl amphodiacetates, alkylsulphoacetates, acyl sarcosinates, acyl lactylates and acyl glutamates. The viscosity of the concentrated base of the invention can advantageously be adjusted by simple dilution with water to the concentration of use and/or by adding small amounts of electrolytes. Detergent products and products for personal care and hygiene comprising the concentrated base of the invention are also described.

Abstract: The invention describes detergent or cosmetic compositions having hydrating and preservative properties and simultaneously anti-dandruff and/or anti-odor properties. These compositions comprise a salt of undecylenoil glutamate and/or undecylenoil hydrolyzate of wheat and/or rice proteins. Since such salts are able to perform also a preservative and hydrating effect the compositions of the invention do no need the addition of further preservative or hydrating agents or, at most, contain concentrations thereof which are not efficacious per se.
