Description

Heavy oil dirt removing hand sanitizer and preparation method thereof

Technical Field

The invention belongs to the technical field of daily chemical washing products, and particularly relates to a heavy oil dirt removing hand sanitizer and a preparation method thereof.

Background

The hand sanitizer on the market at present is mainly developed for the public population, and has only the common decontamination effect or the antibacterial disinfection effect. The cleaning effect on industrial greasy dirt and stubborn stains is poor. Personnel engaged in industries such as machine repair, printing ink, printing, chemical industry, oil extraction, food processing and the like often fill with industrial greasy dirt, are difficult to clean by using common hand washing liquid or perfumed soap, and can only use yellow sand and wood dust for repeatedly rubbing, so that the skin is easily damaged, and a large amount of solid waste is caused.

The Chinese patent application with publication number of CN 102670435A discloses a degreasing hand sanitizer and a preparation method thereof, wherein the hand sanitizer consists of any anionic surfactant selected from sodium dodecyl sulfate, ammonium dodecyl sulfate, fatty alcohol polyoxyethylene ether ammonium sulfate and fatty alcohol polyoxyethylene ether sodium sulfate (AES), and any nonionic surfactant selected from fatty alcohol polyoxyethylene ether, coconut fatty acid diethanolamide and alkylphenol polyoxyethylene ether, and a compound humectant, a chelating agent, a preservative, a pH regulator, a color enhancer, a thickener, a frosting agent, perfume and water. The oil-in-water type detergent is prepared by selecting specific anionic surfactant and nonionic surfactant, and good greasy dirt cleaning effect is obtained. However, the high content of anionic surfactant (8-15 wt%) in the formulation of this patent gives rise to a significant amount of foam and at the same time a disadvantage: most consumers reflect that after using the hand sanitizer, a large amount of generated foam cannot be dissipated in a short time, and a large amount of water is needed to wash the residual foam, so that on one hand, water resources are seriously wasted, on the other hand, the foam washed away by the water is not effectively destroyed, and after washing hands for many times, the foam can be overflowed back into a hand wash basin through a sewer pipe, and the attractiveness and sanitation are affected.

Therefore, a hand sanitizer with heavy oil dirt removing effect and fast foaming and defoaming characteristics is needed at present.

Disclosure of Invention

The invention aims to provide a heavy oil dirt removing hand sanitizer and a preparation method thereof. The hand sanitizer has the characteristics of fast foaming and fast defoaming, has good cleaning effect on industrial greasy dirt and stubborn stains, and is low in irritation and safe to use.

The invention is realized by the following technical scheme:

the heavy oil dirt removing hand sanitizer comprises the following components in percentage by weight: 2 to 5 percent of sodium C10-13 alkyl benzene sulfonate, 2 to 2.5 percent of hexyl decyl alcohol polyether-2 1, 2 to 5 percent of C8-18 and unsaturated C18 amidopropyl betaine, 0.5 to 1 percent of octyl/decyl glucoside, 4 to 8 percent of glycol palmitate, 1 to 3 percent of sodium carbonate, 0.5 to 1 percent of hydroxy tetrahydro methyl pyrimidine carboxylic acid, 2 to 4 percent of emollient, 0.1 to 1 percent of chelating agent, 0.1 to 0.3 percent of preservative, 0.05 to 0.1 percent of essence and the balance of deionized water.

Preferably, the emollient is selected from at least one of water-soluble jojoba oil, glycerol polyether-26, wheat ceramide, sodium tocopheryl phosphate, sodium lactate methyl silanol. Preferably, the emollient is sodium lactate methylsilanol.

Preferably, the chelating agent is at least one selected from the group consisting of sodium dodecyl inositol hexaphosphate, trisodium inositol triphosphate, sodium inositol hexaphosphate, tetrasodium glutamate diacetate, and trisodium N, N-dicarboxymethyl alanine. Preferably, the chelating agent is sodium dodecyl inositol hexaphosphate.

Preferably, the preservative is at least one selected from phenoxyethanol, sodium benzoate, potassium sorbate, ethylhexyl glycerol, propyl parahydroxybenzoate, triclosan, dibutyl hydroxytoluene and methyl benzoate. Preferably, the preservative is composed of phenoxyethanol and ethylhexyl glycerol according to a mass ratio of 1:0.1-0.5.

The heavy oil-removing and hand-washing liquid is prepared by the following steps: adding sodium C10-13 alkylbenzenesulfonate, hexyldecyl polyether-2, C8-18 and unsaturated C18 amidopropyl betaine, octyl/decyl glucoside and glycol palmitate into deionized water, stirring until the system forms uniform transparent liquid, adding sodium carbonate, hydroxy tetrahydro methyl pyrimidine carboxylic acid, an emollient, a chelating agent, a preservative and essence, and stirring until the materials are completely dissolved, thus obtaining the product.

The surfactant type hand cleanser compounded by the anionic surfactant of sodium C10-13 alkylbenzenesulfonate (LAS-Na, CAS RN: 68411-30-3), the nonionic surfactant of hexyldecanol polyether-2 (CAS RN: 52609-19-5) and the zwitterionic surfactant of C8-18 and unsaturated C18 amidopropyl betaine (CAS RN: 147170-44-3) has excellent cleaning effect on industrial greasy dirt and stubborn stains, and has the advantages of quick foaming, quick defoaming, easy cleaning and no water resource waste. The sodium C10-13 alkylbenzenesulfonate is linear alkyl phenyl sulfonate (LAS), is an easily biodegradable anionic surfactant, has excellent decontamination, foaming, emulsification, dispersion, wetting and solubilization performances, but is weak in hard water resistance, and has poor solubility under cold water and hard water conditions, so that a multi-layer vesicle similar to a large onion-like structure is formed, and can be lost during use, so that the use of the multi-layer vesicle is limited. Hexyl decyl alcohol polyether-2 is a nonionic surfactant with excellent decontamination, wetting, penetration, solubilization, emulsification and dispersion properties. The inventor discovers that the C10-13 sodium alkyl benzene sulfonate and the hexyl decyl polyether-2 are compounded for use, and have obvious synergistic effect of removing heavy oil dirt, and the effect is obviously superior to that of independently using the sodium alkyl benzene sulfonate and the hexyl decyl polyether-2, but the foam of a hand washing liquid system is slow to foam and the foam is not rich when the sodium alkyl benzene sulfonate and the hexyl decyl polyether-2 are compounded, and presumably, the foaming effect of the system is influenced due to the low EO number of the hexyl decyl polyether-2. To solve this drawback, the inventors found through extensive experiments that adding a proper amount of a zwitterionic surfactant of C8-18 and unsaturated C18 amidopropyl betaine, in particular the sodium C10-13 alkylbenzenesulfonate: hexyl decyl alcohol polyether-2: the mass ratio of the C8-18 to the unsaturated C18 amidopropyl betaine is 2:1:2, the hand sanitizer not only keeps high-efficiency heavy oil dirt removing capability, but also has the characteristics of quick foaming and quick defoaming, can quickly form rich foam during cleaning, can quickly disappear when water is used for cleaning, has small residue, and the C8-18 and unsaturated C18 amidopropyl betaine can also reduce the irritation of the sodium C10-13 alkylbenzenesulfonate and the hexyldecanol polyether-2 to skin.

Octyl/decyl glucoside is a green solubilizer, has low and stable irritation, can reduce the irritation of other surfactants, increases the solubility, especially increases the solubility of sodium C10-13 alkylbenzenesulfonate, and improves the hard water resistance. The chelating agent can inhibit the exchange of calcium/magnesium ions in hard water and sodium ions of sodium C10-13 alkylbenzenesulfonate to form calcium/magnesium C10-13 alkylbenzenesulfonate which is insoluble in water, so as to avoid the reduction of detergency, and can effectively remove the calcium bond of bonded grease and stains, thereby further improving the removal capability of greasy dirt.

The aqueous solution of sodium carbonate has strong alkalinity, and can generate saponification reaction with carboxyl in the greasy dirt to generate water-soluble soap base and glycerin, promote the dissolution of the greasy dirt and improve detergency. On one hand, the hydroxy-tetrahydro-methyl-pyrimidine carboxylic acid can regulate the alkalinity of a degreasing system, reduce the irritation and corrosiveness to skin, and on the other hand, has the capability of improving the immunity protection of skin cells, effectively stabilizes and repairs skin allergy symptoms, has very strong complexing capability of water molecules, can complex four or five water molecules by one molecule of hydroxy-tetrahydro-methyl-pyrimidine carboxylic acid, can structure free water in cells, and can continuously improve the moisture retention capability of the skin.

The heavy oil dirt removing hand sanitizer is also added with a proper amount of the emollient, preferably sodium lactate methyl silanol, is a perfect combination of bioactive silanol and AHA, can quickly play a role in moisturizing, has longer duration, and gives the skin an obvious smooth feel and a moisturizing feel after being cleaned.

Compared with the prior art, the invention has the following beneficial effects:

the hand sanitizer provided by the invention has excellent heavy oil stain removal and cleaning capabilities, good cleaning effects on industrial greasy dirt and stubborn stains, and has the characteristics of quick foaming and defoaming, can quickly form abundant foam during cleaning, can quickly disappear when water is passed, has little residue, is low in irritation and safe to use, has a certain skin moisturizing effect, and is especially suitable for cleaning hand greasy dirt by personnel engaged in industries such as machine repair, printing ink, printing, chemical industry, oil extraction, food processing and the like.

Detailed Description

Comparative example 5

Comparative example 5 the preparation of a heavy duty hand wash was compared to example 4, except that hydroxy-tetrahydro-methyl-pyrimidine carboxylic acid was absent. The preparation procedure is referred to above in the examples.

Test example one, measurement of foaming Capacity

1. Sample: heavy oil-contaminated hand sanitizers prepared in examples 1-6 and comparative examples 1-4.

2. The method comprises the steps of measuring by adopting a vibration method, adding 0.03g of hand sanitizer to be measured into a colorimetric tube, adding 10mL of distilled water, covering a cover, shaking for 50 times (shaking direction, speed, strength and the like are as consistent as possible), taking down the cover, adding 10mL of distilled water, flushing foam on the wall of the colorimetric tube, recording the foam height again after 5min, taking the initial foam height as a foaming performance measurement of the hand sanitizer, representing the stability of the foam by the foam height after 5min, recording the complete disappearance time of each group of foam, and obtaining the results shown in Table 1.

TABLE 1

Group of	Initial foam height (mm)	Foam height (mm) after 5min	Time to complete foam disappearance (min)
				Example 1	160	8	7
Example 2	166	9	7
				Example 3	174	10	7
Example 4	182	12	7
				Example 5	171	17	8
Example 6	179	19	8
				Comparative example 1	88	0	5
Comparative example 2	198	140	21
				Comparative example 3	190	108	13
Comparative example 4	175	91	10

Note that: the higher the initial foaming height, the better the foaming performance of the hand sanitizer; the smaller the foam height after 5min of foaming, the poor foam stability and high defoaming speed are indicated.

The results show that the heavy oil dirt removing hand sanitizers prepared in the embodiments 1-6 have better foaming performance, high defoaming speed and characteristics of quick foaming and quick defoaming. As is clear from comparative example 1, the formulation does not contain C8-18 and unsaturated C18 amidopropyl betaine, and the hand wash system has poor foaming properties and does not have abundant foam. As is clear from comparative example 2, the formulation does not contain hexyldecanol polyether-2, and the hand sanitizer has better foaming performance, but has low defoaming speed and large residue. From comparative example 3, it is seen that the replacement of hexyldecanol polyether-2 with hexyldecanol polyether-20 in the formulation, while maintaining better foaming properties, slows down the defoaming speed, indicating that hexyldecanol polyether-2 is more beneficial in promoting foam disappearance. As is clear from comparative example 4, the foaming performance of the hand sanitizer system is slightly weakened and the defoaming speed is slightly slowed by replacing the sodium C10-13 alkylbenzenesulfonate with the sodium fatty alcohol polyoxyethylene ether sulfate. The results show that the surfactant type hand cleanser compounded by the sodium alkyl benzene sulfonate C10-13, the hexyldecanol polyether-2, the C8-18 and the unsaturated C18 amidopropyl betaine has the characteristics of fast foaming and fast defoaming.

Test example two, determination of detergency

2. Adding 0.5g of hand sanitizer into a beaker, adding water to 10g, shaking uniformly, dripping pure engine oil, oscillating, dripping until the last drop of engine oil is not dissolved, accurately recording the mass of the hand sanitizer for dissolving the pure engine oil, and representing the relative detergency of the hand sanitizer by using the recorded mass, wherein the result is shown in Table 2.

TABLE 2

Group of	Detergency (g)
		Example 1	1.8
Example 2	1.9
		Example 3	2.1
Example 4	2.2
		Example 5	2.0
Example 6	2.2
		Comparative example 1	1.9
Comparative example 2	1.0
		Comparative example 3	1.7
Comparative example 4	1.4

The results show that the heavy oil-removing and hand-washing liquid prepared in the examples 1-6 has better removal capacity for engine oil, and the detergency is more than or equal to 1.8g. As is clear from comparative example 1, the formulation does not contain C8-18 and unsaturated C18 amidopropyl betaine, has little influence on the degreasing ability of the hand cleanser, and slightly reduces the detergency. As is clear from comparative example 2, the formulation does not contain hexyldecanol polyether-2, has a great influence on degreasing ability of the hand sanitizer, and has significantly reduced detergency. From comparative example 3, it is evident that the detergency of the hand sanitizer is reduced by replacing the hexyldecanol polyether-2 with the hexyldecanol polyether-20 in the formulation, indicating that the combination of the hexyldecanol polyether-2 and the sodium C10-13 alkylbenzene sulfonate is more advantageous for improving the detergency of the hand sanitizer. From comparative example 4, the detergency of the hand cleanser is obviously reduced by replacing the sodium C10-13 alkylbenzenesulfonate with the sodium fatty alcohol polyoxyethylene ether sulfate, and the compound of the sodium hexyl decyl alcohol polyether-2 and the sodium C10-13 alkylbenzenesulfonate is more beneficial to improving the detergency of the hand cleanser. The results show that the surfactant type hand sanitizer compounded by the sodium C10-13 alkylbenzene sulfonate, the hexyldecanol polyether-2, the C8-18 and the unsaturated C18 amidopropyl betaine has better heavy oil stain removal capability, wherein the sodium C10-13 alkylbenzene sulfonate and the hexyldecanol polyether-2 have important effect on the oil stain removal effect of the hand sanitizer.

Test example III, use effect

1. Sample: heavy oil-contaminated hand sanitizers prepared in examples 1-4 and comparative examples 1-5.

2. Subjects were divided into 9 groups and heavy oil-contaminated hand sanitizers prepared in examples 1-4 and comparative examples 1-5 were used, respectively. Each group was 5 people. Each person smears both hands with 5g of engine oil each time, after smearing evenly, washes with corresponding 1g of hand sanitizer, washes with clear water after rubbing for 20 times, evaluates three indexes of deoiling effect, skin irritation and moisturizing effect, wherein each index is divided into 10 minutes at the highest and 1 minute at the lowest, the higher the score is, the lower the skin irritation is, the better the moisturizing effect is, and the results are shown in table 3.

TABLE 3 Table 3

Group of	Deoiling effect	Skin irritation	Moisturizing effect
				Example 1	8	9	9
Example 2	8.5	9.5	9.5
				Example 3	9	9.5	9.5
Example 4	10	10	10
				Comparative example 1	8.5	8	10
Comparative example 2	4	9.5	10
				Comparative example 3	7.5	9.5	10
Comparative example 4	6	8	10
				Comparative example 5	9.5	6.5	8

The results show that the heavy oil removal hand sanitizers prepared in the embodiments 1-4 have good degreasing effect, low skin irritation and good moisturizing effect, and the product in the embodiment 4 has the most excellent service performance. The effect is better than that of the products of comparative examples 1-5.
