Description
Technical Field
The invention relates to the field of daily chemicals, in particular to a composition for reducing irritation of a detergent and application thereof.
Background
In recent years, with the continuous development of economy, the living standard of people is rapidly improved, the requirements of consumers on the quality of products are higher and higher, and the products are not limited to the basic functions of the products, for example, detergents such as laundry detergent, washing powder and the like are required to have strong detergency, moderate and no stimulation; when personal washing and protecting products such as shower gel, shampoo, liquid soap and the like are purchased, the mildness of the products can be considered preferentially, and the products with skin-protecting components or effects are more popular.
At present, hand-washing detergents (such as laundry detergent, washing powder, liquid detergent and the like) on the market are various, and due to low price and strong cleaning power, anionic surfactants represented by alkyl polyoxyethylene ether sodium sulfate and sodium alkyl benzene sulfonate are mainly used as effective components. However, they are highly irritating to the skin, and frequent contact with the skin for a long period of time causes changes in the properties of the stratum corneum and the epidermis of the skin, leading to problems such as skin roughness, dryness, itching, and redness. Part of the products are introduced with nonionic surfactants as effective components to reduce the dosage of anionic surfactants, thereby reducing the skin irritation of the detergent. Some products reduce skin irritation by lowering the pH. In general, however, these strategies have had limited effectiveness, and current hand-wash detergents are still relatively irritating to the skin and tend to cause skin irritation in sensitive skin consumers.
Patent application No. CN202110809339.6 discloses a detergent composition having both low irritancy, high cleaning power and low temperature stability, comprising: (a) an anionic surface active agent; (b) amine oxide amphoteric surfactants; (c) a nonionic surfactant; (d) a irritation-improving ingredient; the irritation-improving component is at least one of sodium lactate, sodium pyrrolidone carboxylate, and sodium hyaluronate, and preferably sodium lactate. Although the irritation-improving ingredient used in this patent can reduce the irritation of the detergent to some extent, the effect is limited, and only when used in combination with a specific detergent system using the component (b) can the detergent as a whole exhibit low irritation, and when used in a conventional detergent formulation, the detergent still has high irritation.
Disclosure of Invention
In order to solve the technical problem that the irritation of the detergent is difficult to obviously reduce by the existing irritation improving components, the invention provides a composition for reducing the irritation of the detergent and application thereof. According to the invention, the alkyl glycoside sulfosuccinate ester salt, the glyceryl polyether and the sodium lactate are compounded, so that the irritation of the conventional detergent can be obviously reduced, and the adverse effect on the skin is reduced.
The specific technical scheme of the invention is as follows:
in a first aspect, the present invention provides the use of an alkyl glycoside sulfosuccinate salt in the preparation of an adjunct for reducing the irritancy of a detergent.
The irritation of hand-washing detergents is a key factor that causes skin changes and affects the use experience. Anionic surfactants such as sodium alkyl benzene sulphonate can penetrate the stratum corneum membrane and destroy its integrity by degreasing, which can lead to rough and even painful skin surface texture. Therefore, irritation is reduced, and adverse effects on the skin can be significantly reduced.
Theoretical analysis and experimental research show that the alkyl glycoside sulfosuccinate can be used for reducing the irritation of the detergent, and the mechanism is as follows: the alkyl glycoside sulfosuccinate salt contains a plurality of strong hydrophilic groups, has strong hydrophilicity, is easier to exist in water and then is washed away in the washing process, and is not easy to be placed on the skin. And because of the structural characteristics, the detergent has the characteristics of both non-ions and anions, and has good affinity with an anionic surfactant and a non-ionic surfactant which are commonly used in detergents according to the principle of similar intermiscibility, the anionic surfactant and the non-ionic surfactant which are commonly used in detergents can be easily washed away by water, so that the amount of the residual surfactant on the skin is reduced, and the irritation is greatly reduced.
Preferably, the alkyl glycoside sulfosuccinate salt has the formula:
wherein R is C 8～16 N is 1.0 to 1.4.
Further, in the alkyl glycoside sulfosuccinate ester salt, R is C 12～16 Alkyl group of (1).
In the alkyl glycoside sulfosuccinate ester salt, under the influence of strong hydrophilic groups, the lipophilic ability of the alkyl glycoside sulfosuccinate ester salt needs to be properly balanced, so that the alkyl glycoside sulfosuccinate ester salt can better affinity other surfactants in a detergent, thereby realizing better elution effect and reducing the irritation of the detergent, and therefore, when the alkyl chain is at C 8～16 When the alkyl chain adopts C, the effect is better 12～16 In this case, the effect of reducing the irritation of the detergent can be further improved.
When the polymerization degree (n) of the glycoside is between 1.0 and 1.4, the distribution range is narrow, and the influence is relatively small.
In a second aspect, the present invention provides a composition for reducing the irritancy of detergents, the composition comprising the following components: alkyl glycoside sulfosuccinate ester salt, glycerol polyether and sodium lactate.
According to the invention, through compounding the three specific components, the irritation of the conventional detergent can be obviously reduced, the adverse effect on skin is reduced, and the skin feel of the detergent after use is improved, specifically:
1) Addition of alkyl glycoside sulfosuccinate salt:
the alkyl glycoside sulfosuccinate ester salt can promote the common anionic surfactant and nonionic surfactant in the detergent to be washed away by water, reduce the residual quantity on the skin and further reduce the irritation of the detergent.
2) Compounding sodium lactate and glycerol polyether:
maintaining the proper water content in the stratum corneum layer of the skin is important to its function. If the outer layer of the stratum corneum does not have sufficient moisture to remain normally flexible, the skin will scale and become itchy, with reduced skin permeability. If the outer layer of the skin is too much water, it causes the stratum corneum to absorb 3-5 times its own weight of bound water, causing the skin to swell and wrinkle, while the skin permeability increases. Therefore, in addition to reducing irritation, there is a need for ingredients that help the stratum corneum maintain its barrier and water retention functions.
The sodium lactate is a component occupying one fourth of the stratum corneum of human skin, and can reduce the irritation of a detergent and bring a certain moisturizing effect when added into the detergent; the glyceryl polyether is used as a humectant, and can improve the soft and smooth texture of skin. However, the team of the present invention finds, through theoretical analysis and experimental research, that in the detergent, when sodium lactate or glyceryl polyether is used alone, the effect of reducing the irritation of the detergent is limited, and when sodium lactate and glyceryl polyether are compounded, a synergistic effect of "1+1 >" 2 "can be generated, and the presumed mechanism is as follows: cross-linking hydrogen bonds can be formed among the glyceryl polyether, the sodium lactate and water molecules, a hydration film is formed on the surface of the skin, water volatilization is prevented, the moisturizing effect is better exerted, and smoothness is also brought.
No combination of any moisturizer with sodium lactate allowed a comparable synergistic effect to glyceryl polyether to be achieved, because: firstly, a cross-linking hydrogen bond is formed to form a latticed structure, so that the water-retaining effect is good, and the moisture retention is realized; the glycerin polyether is secondarily formed into a film layer structure on the skin surface, so that the integral water locking and moisture preservation can be realized, and the glycerin polyether is based on the unique branched long polyether chain structure, so that the skin surface can be comprehensively and uniformly covered, and the smoothness is brought while the moisture preservation is realized. Conventional other moisturizers, such as sodium pyrrolidone carboxylate, sodium hyaluronate and the like, do not form similar structures, so that the same synergistic effect is not achieved.
3) Compounding sodium lactate, glyceryl polyether and alkyl glycoside sulfosuccinate salt:
the team of the invention finds that when only sodium lactate and glyceryl polyether are added into a detergent, the detergent does not show obvious effect of moisturizing and smoothing skin, but after the sodium lactate and the glyceryl polyether are compounded with alkyl glycoside sulfosuccinate ester salt, a synergistic effect can be generated to obviously reduce the irritation of the detergent, and the detergent has the characteristic of moisturizing and smoothing skin, and the presumed mechanism is as follows: when the alkyl glycoside sulfosuccinate ester salt is not added, more components commonly used in detergents, such as surfactants and auxiliaries, remain on the skin, and the formation of a cross-linking hydrogen bond structure and a hydration film layer structure among the glyceryl polyether, the sodium lactate and water molecules is destroyed.
Preferably, the mass ratio of the glyceryl polyether to the sodium lactate is (0.1-1): (0.1-1).
Based on the synergistic action mechanism between the glyceryl polyether and the sodium lactate, the invention discovers that when the ratio of the glyceryl polyether to the sodium lactate is too high or too low, the effects of reducing the irritation of the detergent and improving the skin feel of the detergent after use are poor, and specifically: when the relative amount of the glyceryl polyether is too small, the smooth feeling is weakened, which is probably because a certain amount of the glyceryl polyether is required for the formation of a hydration film layer; when the relative amount of sodium lactate is too small, the irritation-reducing effect and the moisturizing effect are reduced, and it is presumed that the moisturizing effect of sodium lactate is superior to that of glycerin polyether.
Preferably, the ratio of the total mass of the glyceryl polyether and the sodium lactate to the mass of the alkyl glycoside sulfosuccinate salt is (0.2-3): (0.3-3).
The invention is based on a synergistic action mechanism between the glyceryl polyether and sodium lactate and the alkyl glycoside sulfosuccinate salt, and finds that when the ratio of the total mass of the glyceryl polyether and the sodium lactate to the mass of the alkyl glycoside sulfosuccinate salt is too large or too small, the effects of reducing the irritation of a detergent and improving the skin feel of the detergent after use are poor, specifically: when the relative amount of the glyceryl polyether and the sodium lactate is too small, although the irritation is still obviously reduced, the moisturizing effect and the smooth feeling are obviously reduced, on one hand, the better effect is realized because the amount of the glyceryl polyether and the sodium lactate is insufficient, on the other hand, the excessive alkyl glycoside sulfosuccinate salt can also elute part of the glyceryl polyether and the sodium lactate, so that the residual amount on the skin is less, and the effect is less ideal; when the relative amount of the alkyl glycoside sulfosuccinate salt is too small, the decrease in irritation is not significant, presumably because it is insufficient to significantly reduce irritation caused by usual detergent ingredients remaining on the skin, such as sodium alkylbenzenesulfonate, etc., and the relative amounts of glycerin polyether adsorbed on the skin and sodium lactate are decreased, and the moisturizing effect and the smoothing effect are also not significant.
Preferably, the alkyl glycoside sulfosuccinate salt has the following formula:
wherein R is C 8～16 N is 1.0 to 1.4.
Further, in the alkyl glycoside sulfosuccinate ester salt, R is C 12～16 The alkyl group of (1).
Preferably, the glyceryl polyether comprises one or more of glyceryl polyether-12, glyceryl polyether-18 and glyceryl polyether-26.
When the three glyceryl polyethers are selected, the irritation of the detergent can be reduced to a greater extent, and the skin feeling after the detergent is used can be improved, because: the polyether chain length is moderate, and the polyether chain can better form a cross-linking hydrogen bond with sodium lactate and water to form a hydration film, otherwise, if the polyether chain length is too short, the cross-linking hydrogen bond network structure is possibly incomplete, and if the polyether chain length is too long, the hydrophilicity is possibly too strong, and the residual quantity on skin is insufficient.
In a third aspect, the invention provides the use of the composition as an adjunct in reducing the irritancy of detergents.
Compared with the prior art, the invention has the following advantages:
(1) According to the invention, the three specific components are compounded, the alkyl glycoside sulfosuccinate salt is used for promoting the common surfactant in the detergent to be washed away by water, and the synergistic effect between the glyceryl polyether and the sodium lactate and the synergistic effect between the sodium lactate and the alkyl glycoside sulfosuccinate salt are used, so that the irritation of the conventional detergent can be obviously reduced, the adverse effect of the conventional detergent on the skin can be reduced, and the skin feel of the detergent after use can be improved;
(2) By controlling the proportion of the three components, good synergistic effects can be generated between the glyceryl polyether and the sodium lactate and between the glyceryl polyether, the sodium lactate and the alkyl glycoside sulfosuccinate ester salt, the irritation of the detergent is effectively reduced, and the skin feel of the detergent after use is improved.

TABLE 3
Application examples 1 to 10 and comparative application examples 1 to 6
The compositions prepared in examples 1 to 10 and comparative examples 1 to 6 were taken and formulated into detergents of application examples 1 to 10 and comparative application examples 1 to 6, respectively, according to the following procedure:
(1) Weighing the following raw materials in percentage by mass: 8% of dodecyl benzene sulfonic acid, 4% of polyethoxylated fatty alcohol, 2% of ethoxylated alkyl sodium sulfate, 0.5% of triethanolamine, 0.6% of trisodium citrate dihydrate, 0.1% of kathon preservative and 81.8% of deionized water; uniformly mixing to obtain a primary mixture;

Comparative application example 7
The difference between the application example and the application example 1 is that the composition for reducing the irritation of the detergent is replaced by the deionized water in the step (2), namely, the composition for reducing the irritation of the detergent is not added to the detergent of the application example.
Test example 1: irritation test
The samples to be tested (detergents of application examples 1 to 10 and comparative application examples 1 to 7) were formulated into solutions with a mass fraction of 10 wt%. Taking 50mL, adding 2g of zein, stirring for 2h at 25 ℃, observing once every 10min, and adding the zein according to the situation to ensure that the solution contains enough undissolved zein. Then standing and filtering, and measuring the mass fraction (A) of nitrogen in the filtrate by a micro Kjeldahl method. Taking another 50mL of the detergent solution without adding the zein to carry out a blank experiment, and measuring the mass fraction (B) of nitrogen in the detergent solution without adding the zein.
Zein value = a-B, zein value is expressed in mg (or g) of nitrogen contained in the solution, N mg (g)/L.
The irritancy of surfactants can be classified by Zein number into 3:
(1) Surfactants with Zein values greater than N4 g/L solution are "strongly irritating".
(2) The surfactant with Zein value in N2-4 g/L solution is low in irritation.
(3) Surfactants having a Zein value of less than N2 g/L solution are "non-irritating".
The test results are shown in Table 4.
