Concentrated base for detergent products and products for personal care and hygiene comprising a combination of at least three non-ethoxylated surfactants

A concentrated base, for a detergent product or a product for personal care and hygiene, consisting of a combination of at least three surfactants selected from the group consisting of acylmethyltaurates of formula (I), alkylamidopropylbetaines of formula (II), alkyl amphoacetates of formula (III), alkyl amphodiacetates of formula (IV), alkylsulphoacetates of formula (V), acylsarcosinates of formula (VI), acyl lactylates of formulae (VII) and (VII)′ and acylglutamates of formula (VIII) and water, wherein:

• formula (I) is:
• wherein R is a linear or branched, saturated or unsaturated alkyl radical, having from 3 to 30 carbon atoms and M+ is H+ or a cation of an organic or inorganic base;
• formula (II) is:
• wherein R1 is a saturated or unsaturated, linear or branched alkyl radical, having from 3 to 30 carbon atoms, M+ is H+ or a cation of an organic or inorganic base, X− is an inorganic or organic anion;
• formula (III) is:
• wherein R2 is a saturated or unsaturated, linear or branched alkyl radical, having from 3 to 30 carbon atoms, M+ is H+ or a cation of an organic or inorganic base;
• formula (IV) is:
• wherein R3 is a saturated or unsaturated, linear or branched alkyl radical, having from 3 to 30 carbon atoms, preferably derived from coco, M+ is H+ or a cation of an organic or inorganic base;
• formula (V) is:
• wherein R4 is a saturated or unsaturated, linear or branched alkyl radical, having from 3 to 30 carbon atoms and M+ is H+ or a cation of an organic or inorganic base;
• formula (VI) is:
• wherein R5 is a saturated or unsaturated, linear or branched alkyl radical, having from 3 to 30 carbon atoms and M+ is H+ or a cation of an organic or inorganic base;
• formulae (VII) and (VII)′ are:
• wherein R6 and R7 are, independently of one another, a saturated or unsaturated, linear or branched alkyl radical, having from 3 to 30 carbon atoms and M+ is H+ or a cation of an organic or inorganic base;
• formula (VIII) is:
• wherein R8 is a saturated or unsaturated, linear or branched alkyl radical, having from 3 to 30 carbon atoms and M+ is H+ or a cation of an organic or inorganic base.
