A rheology modifier which includes a mixture of short and long chain fatty acid esters is suitable for use in liquid surfactant-based compositions. A surfactant-based composition includes a surfactant, the rheology modifier, and water. The rheology modifier includes a mixture of alkyl glycoside fatty acid esters including a long chain fatty acid ester of an alkyl glycoside and a short chain fatty acid ester of an alkyl glycoside. The long chain fatty acid ester includes at least one fatty acid residue: R
1
(O)O—, wherein R
1
is a C
12
or higher hydrocarbon. The short chain fatty acid ester includes least one fatty acid residue: R
2
(O)O—, wherein R
2
is a C
6
-C
10
hydrocarbon.
A liquid detergent composition which comprises:
(A) at least one N-acylated acidic amino acid represented by general formula (I) or a salt thereof;
wherein R₁ represents an alkyl group or an alkenyl group having 7 to 21 carbon atoms; M₁ and M₂ each represents hydrogen, an alkali metal or an alkanolammonium ion; and m represents an integer of 1 or 2,
and (B) at least one aliphatic sulfonic acid selected from compounds represented by general formula (II) or (III) or salts thereof;
R₂-CH=CH(CH₂)nSO₃M₃ (II)
R₂--(CH₂)nCH₂SO₃M₃ (III)
wherein R₂ represents an alkyl group having 7 to 15 carbon atoms; n represents 0 or an integer of 1 to 5; and M₃ represents hydrogen, an alkali metal or an alkanolammonium ion;
wherein the ratio (A)/(B) of component (A) to component (B) is 3/7 to 7/3 by weight and the total concentration of component (A) and component (B) in the composition is in a range of 4 to 30 wt%.
A composition suitable for topical application to mammalian skin and hair for inducing, maintaining or increasing hair growth comprises a hair growth promoter chosen from glutamic acid derivatives and salts thereof. The composition preferably also comprises an activity enhancer which may be chosen from hair growth stimulants, penetration enhancers and cationic polymers.

The present invention provides a method of efficiently producing an N-acyl-amino group-containing compound by an enzymatic method. Specifically, the present invention provides a method of producing an N-acyl-amino group-containing compound, comprising producing the N-acyl-amino group-containing compound by reacting an amino group-containing compound with a carboxyl group-containing compound in the presence of an enzyme having an ability to bond a carboxyl group and an amino group in an ATP dependent manner to form an amide bond.
本发明提供了一种通过酶法高效生产含 N-酰基氨基化合物的方法。具体地说,本发明提供了一种生产含 N-酰基-氨基化合物的方法,包括在一种酶的存在下,使一种含氨基的化合物与一种含羧基的化合物反应生成含 N-酰基-氨基化合物,该酶具有以依赖 ATP 的方式键合羧基和氨基以形成酰胺键的能力。
