Description

The aqueous surfactant prepared product that is used for the gentleness of cosmetics and detergent

Technical field

The present invention relates to be used for the aqueous surfactant prepared product of the gentleness of cosmetics and detergent.

Background technology

Betanin, particularly amido propyl betaine, as amphoteric surfactant, especially for the cleaning agent prepared product of hair shampoo article and skin, as shampoo, frothy gel and bath gels, it is to the skin gentleness, and is used for individual body cosmetic.Except other good properties, they have also improved the Dermatology character of anion surfactant and non-ionic surface active agent and have made dermal sensation comfortable.In addition, betanin also can be advantageously used in cleaning agent, as tableware rinse aid and exquisite fabric detergent.

As existing betanin, use the fatty acid amide CAB especially, have 8-18 or 12-18 carbon atom usually at the fatty acid group of betanin described in the mixture.Coco-nut oil fatty acid amido propyl betaine with following composition is proved effective especially.

Fatty acid group about 7% with 8 carbon atoms

Fatty acid group about 6% with 10 carbon atoms

Fatty acid group about 49% with 12 carbon atoms

Fatty acid group about 19% with 14 carbon atoms

Fatty acid group about 9% with 16 carbon atoms

Fatty acid group about 10% with 18 carbon atoms

Though gentle surfactant formulation can be made by the coco-nut oil fatty acid amido propyl betaine, but the commercial aqueous solution of the routine of betanin or its water dilution have tangible potential stimulus, this can be by skin and mucosa test determination, and the in vitro tests method in the modern times of also available mensuration stimulation (as the erythrocyte test) is measured.

In addition, consumer makes the gentle especially surfactant of acquisition very necessary to the cosmetics prepared product of milder and the lasting demand of cleaning agent.

Therefore, the objective of the invention is to find to satisfy especially gentle, the low prepared product that stimulates that high skin-friendliness requires.

Summary of the invention

The objective of the invention is to be used for the aqueous surfactant prepared product of cosmetics and detergent.

The specific embodiment

The inventor has unexpectedly found the surfactant prepared product, its comprise have following general formula betanin as surfactant, the amount of described betanin is 1.0 weight %-40 weight % of described prepared product:

Wherein, R is the alkyl with 7-21 carbon atom, and in the described betanin of 20 weight %-100 weight %, the R group is the alkyl with 7-9 carbon atom.

Compare existing prepared product, the obvious milder of these prepared products of the present invention, zest are lower, when as cleanser liquid (face lotion), shampoo or lotion (lotion) time, only cause minimal irritation or almost not stimulation.

Be unexpectedly, the betanin that particularly has relative short-chain fat acid groups demonstrates gentle especially character, and in technical literature, special is the surfactant with short-chain fat acid groups owing to those characteristics with enhanced stimulation character.

For example, from document Seifen-

-Fette-Waches, Vol.93, No.15/1967 (on July 19th, 1967), 521 pages, can infer surfactant with shorter alkyl chain, its Dermatology character satisfaction is lower.Therefore recommend cosmetics department to use surfactant with 12-14 or 12-18 carbon atom alkyl chain.

Same, Deutsche Bundespatent 3011549 instructions:, have the formulation milder that the alkyl ether sulphate of 14 carbon atom alkyls of vast scale is more made with respect to the alkyl ether sulphate of 14 carbon atom groups of twelve carbon atom group with vast scale more and smaller scale.

The amount of the described betanin that prepared product of the present invention comprises is that 1.5 weight %-20 weight % of described prepared product are suitable.

The alkyl that the described betanin of 40 weight %-100 weight % has 7-9 carbon atom is favourable.

In particularly preferred prepared product, has the alkyl of 7-9 carbon atom greater than the described betanin of 90 weight %.

Prepared product of the present invention can comprise anion surfactant.As the anion surfactant that is fit to, what can mention especially is that alkyl ether sulphate (further mentioning glycerol one sulfuric ester), alkyl ether carboxylic acid and their alkali metal salt are as detergent gentleness, skin-compatible.

Long acyl sarcosinate or their alkali metal salt as sodium lauroyl sarcosine, are preferred analog anion surfactants.

The anion surfactant of other suitable scope of the invention has the alkali metal salt of the half ester of α-olefin sulfonic acid ester, alkyl sulfonic ester and their salt, particularly 2-Sulfosuccinic acid.

In addition, prepared product of the present invention also can comprise non-ionic surface active agent.Preferred nonionic belongs to the alkyl polyglucoside class, and its general formula is:

R-O(R ¹O) _n-Z _x

Wherein, R is the alkyl with 8-18 carbon atom, R ¹Be ethylidene or propylidene, Z is the glycosyl with 5-6 carbon atom, and n is the number of 0-10, and x is the number of 1-5.

Though have the alkyl polyglucoside of above-mentioned general formula and be the preferred nonionic surfactants in the present composition, also can adopt other non-ionic surface active agent or preferably adopt their mixture, substitute above-mentioned non-ionic surface active agent.Described other non-ionic surface active agent is, for example fatty acid ester, fatty acid polyethylene glycol ester, alcohol ethoxylate and the oxirane of polyhydric alcohol (as glycerol) and the mix products of expoxy propane.Other non-ionic surfactant component can be the two alkanolamides of amine oxide and fatty acid monoalkylol amide and fatty acid.

The aqueous surfactant prepared product of gentleness of the present invention can comprise all substances of using usually in such reagent.

As these materials, enumerated stabilizing agent; Aromatic oil; Thickening agent can derive from associative thickeners class or polymeric viscosifier class, as polyacrylic acid and its derivant, cellulose derivative and alginate esters; Dyestuff; Conditioning and components of cosmetics are as cationic polymer, amphiphilic polymers, lanolin derivative, cholesterol, pantothenic acid (pentothenic acid), polydimethylsiloxane or their derivant; Antiseptic or the like.

Each component stirred in water together make product of the present invention.Also can adopt the mixture of different component.

By the contrast of following embodiment, shown the beat all mild action of betanin in the prepared product of the present invention, in the described betanin greater than 20% fatty acid group derived from C ₈/ C ₁₀Fatty acid.Given percent is percetage by weight.Following embodiment is used to explain the present invention, but is not used in restriction the present invention.

Embodiment 1

By a kind of in vitro method, i.e. erythrocyte test (RBC) is investigated derived from the physiological compatibility of the fatty acid amide CAB of the fatty acid of different chain length.J.W.Pape and U.Hoppe be at magazine Arzneim.-Forsch./Drug Res.40, and 498, the RBC test has been described in (1990), describe according to this among the present invention and implement the RBC test.

The degeneration of the destruction of the hemocyte that measurement is caused by molten born of the same parents (lysis) and the hemoglobin of release, with the evaluation table surface-active agent to whole cyto-architectural typical stimulation.The result is expressed as L/D, the merchant of instant born of the same parents (L) and degeneration (D).The L/D value is more little, and the stimulation of material or formulation is big more.

Table 1 has been summarized The above results.Be the contraction of used fatty acid amide CAB below:
