Description

Personal care composition, preparation method and application

The present application relies on and claims priority from chinese patent application 202111395217.3 filed on 11/23 of 2021, which is incorporated herein by reference in its entirety.

Technical Field

The invention relates to the field of daily chemical products, in particular to a personal care composition, a preparation method and application.

Background

In general, personal wash products such as shampoos and body washes use anionic surfactants as the main surfactant. Because of the need for good foaming properties, most commercially available personal care compositions, such as body washes, shampoos, hand soaps, and the like, are based on sulfate-containing surfactants such as SLS (sodium lauryl sulfate) or SLES (sodium lauryl ether sulfate). While these surfactants have good foaming properties and can be easily thickened, there has been growing concern in the marketplace for the side effects of these and other sulfate-containing surfactants on the skin and body. At the same time, sulfate-based surfactants have a tendency to overdry the skin or hair, and thus consumers prefer to use products that do not contain sulfate-based surfactants.

To meet the needs of consumers desiring milder compositions, other surfactants (e.g., nonionic and/or amphoteric surfactants) are often used as the primary surfactant instead of sulfate anionic surfactants (e.g., CN106456479a discloses a sulfate-free personal care combination using amphoteric surfactants as the primary surfactant), however, the foaming and/or cleaning performance of these compositions tends to be significantly less than that of anionic primary surfactant compositions. Another approach to providing mildness is to use milder anionic surfactants. Among such mild anionic surfactants, N-acyl amino acids and salts thereof may be used. However, such surfactant-based compositions tend to suffer from a number of problems compared to sulfate-based compositions, mainly one or more of the following: 1. foam is difficult to achieve the same level of sulfate; 2. it is difficult to thicken sufficiently to provide good organoleptic properties. Such cleansers do not remain on the hair or skin during and/or after application and can drip and flow into the eyes, mouth, ears, or nasal passages of the user. This can lead to an unpleasant consumer experience. Currently, two approaches are used to thicken sulfate-free detergent formulations. One approach involves the use of high levels of non-sulfate surfactants to exert the structural properties of such ingredients. This approach is most common but also expensive. The second approach involves the use of high levels of rheology modifiers; however, these components may cause problems such as foam reduction and difficulty in dispersion. 3. It is difficult to form an isotropic transparent liquid. 4. The interaction of amino acid surface activity and cationic conditioning polymer leads to unstable system and turbidity, precipitation and delamination. In view of this, the patent CN111278416 a by the baby company specifically designs a system with low inorganic salt content to solve this problem; 5. the system is fragile, has poor tolerance to electrolyte, or has a narrower pH applicable range. As with the above problems, the presence of the electrolyte may disrupt the isotropy of the N-acyl amino acid salt surfactant, further affecting the stability of the system.

N-alkanoyl taurates are a mild type of amino acid surfactant of great interest and there have been some prior patents on the use of sodium N-alkanoyl taurates. It is noted that the N-alkanoyl taurates or N-acyl taurates mentioned in the previous patents are all, however, N-methylalkanoyl taurates or N-methylalkanoyl taurates. The same problems as described above apply to compositions comprising N-methylalkanoyl taurates as the primary surfactant and to compositions comprising other N-acyl amino acid salts as the primary surfactant, and many of the patents concerned are also directed to solutions around these problems. The senior patent CN103702656 uses taurine derivative type surfactant as the main anionic surfactant for the anti-decoloring shampoo, but sodium cocoanut fatty acid methyl taurate is used in the examples. Examples of N-alkanoyl taurates are not truly taught in the patent. The senior patent CN107205907 adopts a method of adding a large amount of sugar and/or sugar alcohol to solve the viscosity problem of the composition of the methyl taurine derivative, thereby not only greatly increasing the cost of the composition, but also causing unnecessary resource waste. U.S. patent PCT/EP2018/064336 is formulated with sodium cocoyl isethionate and N-acyl methyl taurate, and glycerin and a small amount of amphoteric surfactant to achieve a viscosity and transparency to form an isotropic solution. The invention of the patent CN103655240 is modified sodium cocoyl taurate which is formed by modifying sodium cocoyl taurate and can be thickened; patent CN107468531a uses N-alkanoylalanine salts, N-alkanoylsarcosinates, N-methylalkanoyl taurates as anionic surfactants instead of sulfate anionic surfactants, with emphasis also being given to solving the transparency and viscosity problems of the composition. In the comparative example of patent CN110582266a, sodium methyl cocoyl taurate alone as the anionic surfactant was difficult to achieve proper transparency and viscosity even at low levels of use in the composition. The primary content of the senior patents CN101928645A and CN1935967a is to solve the problem of slippery feel of the cleaning composition by using N-methyltaurine salts of N-acyl methyltaurine or alkyl sulfate. There is no real solution to the problem of replacing sulfate surfactants and therefore creating a problem. Patent CN201710115813.9 discloses a face-cleaning gel, which comprises the following components: an anionic surfactant selected from the group consisting of alkanoylglycinates, alkanoyl taurates and mixtures thereof, wherein the alkanoyl taurate is also, in the examples, sodium methyl cocoyl taurate. Patent CN109481352 relates to sodium methyl cocoyl taurate; patent CN111135103 also uses fatty acyl methyl taurates. To date, the directory of chemicals available in China IECSC and the catalogue of used cosmetic raw materials for various versions of China have not included cocoyl taurates. Therefore, there is no product in China which uses alkanoyl taurates as the main surfactant.

The present inventors have surprisingly found that the above prior art problems can be solved almost perfectly by using a composition of sodium alkanoyl taurate as the main surfactant, while assisting in amphoteric surfactant.

1. Composition viscosity and foam test in the present invention

The test method comprises the following steps:

(1) Viscosity:

the viscosity and flow properties of the liquid products were measured using a GB/T15357 surfactant and detergent rotational viscometer, with a 25℃selection.

(2) Transparency:

test instrument: 721 visible spectrophotometer

The testing method comprises the following steps: at 600nm, the transmittance of each example was measured, and the transmittance exceeding or equal to 85% was recorded as transparent, indicated by o, and the transmittance less than 85% was recorded as opaque, indicated by x.

(3) Foam:

test instrument: SITA foam tester

The testing method comprises the following steps: 2g of the composition in each example was taken, 150mg/kg of hard water was added to 500ml, and the mixture was stirred at 1000rpm at a constant temperature of 40℃for 30 seconds, and the amount of foam was recorded.

As a personal care cleansing article, it is desirable to have a suitable foaming capacity, typically requiring more than 800mL of foam.

2. Mild testing of compositions according to the invention

The test method comprises the following steps: with reference to the SN/T2329-2009 cosmetic eye irritation/corrosiveness chick embryo chorioallantoic membrane test, 6 replicates were set per group using IS scoring method.

Example 1

Sodium N-alkanoyl taurates and cocamidopropyl betaines, combined at 25% total surfactant, were compared to either one-part sodium N-alkanoyl taurates (comparative example 1) or cocamidopropyl betaines (comparative example 2) and with the same pH (i.e., 5.5).

Table 1 (the contents of the components are in weight percent)

Very significantly, the viscosity of example 1 was in line with the normal personal care product range, sodium N-alkanoyl taurates alone exhibited an unstable layered state, while cocamidopropyl betaine alone was too low in viscosity. At the same time, the foaming capacity (initial foam amount) and foam stabilizing capacity (foam amount for 5 minutes) of example 1 were also significantly better than those of sodium N-alkanoyl taurate or cocamidopropyl betaine alone.

Likewise, the combination of sodium methyl cocoyl taurate and amphoteric surfactant in comparative example 3 had a very low viscosity and did not achieve a clear appearance, while the foam was slightly worse.

Example 2

At 15% total surfactant content, the system pH was adjusted to 5.5 and polyquaternium 10 was added to improve conditioning performance.

Table 2 (the contents of the components are in weight percent)

Foam: order from good to bad: example 2 > comparative example 5 > comparative example 4, i.e., sodium cocoyl taurate combination > sodium methyl cocoyl taurate combination > lauryl ether sulfate combination

Conditioning effect: as can be seen from the cationic batt, example 2 and comparative example 5 are much more effective than the sulfate combination of comparative example 4.

Mildness: as can be seen from the values of the irritation, example 2 and comparative example 5 are almost as effective as the sulfate combination of comparative example 4.

Viscosity: conditioning with electrolyte (sodium chloride), see fig. 2; it can be seen that example 2 and comparative example 4 both have good electrolyte compatibility, while the sodium methyl cocoyl taurate combination (comparative example 5) clearly fails to increase viscosity using an electrolyte and is prone to instability (cloudiness).

Example 3

The total surfactant content was compared to less than 7% by using a combination of 2 amphoteric surfactants in combination with nonionic surfactants at a total surfactant content of 14%.

Table 3 (the contents of the components are in weight percent)

Referring to fig. 3, as in example 2, example 3 can be adjusted to obtain a suitable viscosity using an electrolyte, and when the total surfactant content is less than 7% (comparative example 6 to example 3, comparative example 7 to example 2), it is difficult to achieve a desired viscosity.

The compositions and proportions of examples 4-10 are shown in the following table:

table 4 (the contents of the components are in weight percent)

TABLE 5

Example 11 is an application of a basic facial foam, which can be seen to be low in viscosity, convenient for the foam to pump out, abundant in foam quantity, transparent in appearance and low in irritation.

Example 12 is a basic hair washing gel application, has high viscosity, but is convenient to extrude (generally has viscosity exceeding 40000 and is difficult to extrude), has abundant foam, high transparency and low irritation.

Example 13 is a basic shampoo application with proper viscosity (shampoo viscosity is generally required to be 3000-15000), rich foam, high transparency and low irritation.

Comparative example 8 and comparative example 9 are single sodium cocoyl taurate and cocamidopropyl betaine. As can be clearly seen by comparison with example 11, the single component is free of viscosity and the combination thickens; the amount of single component foam is significantly lower than the amount of composition foam; the single component is more irritating than the composition; the single-component sodium alkanoyl taurate has small solubility below 20 ℃, and the composition has large solubility and is transparent. The proper proportion of the sodium alkanoyl taurate and the amphoteric surfactant can obviously enhance the efficiency and solve the application difficulties such as thickening, foam, transparency, mildness and the like.

Table 6 (the contents of the components are in weight percent)

* The pH value is adjusted to 5.6-5.8.

Examples 14 and 16 are based shampoo applications, and example 15 is based shampoo gel. The viscosity is proper, the foam is rich, the transparency is good, and the irritation is low.

In contrast, in comparative example 10, the amount of cocoyl sodium taurate was high, the amount of amphoteric surfactant was too small, and a paste was finally formed, and the viscosity was also meaningless, which was difficult to extrude in practical applications.

In comparative example 11, sodium lauroyl sarcosinate, another amino acid surfactant, was used instead of sodium cocoyl taurate, and the other ingredients were consistent, but the final viscosity was significantly reduced, and it was difficult to form a suitable shampoo viscosity.

Table 7 (the contents of the components are in weight percent)

TABLE 8

The products described in Table 4 and Table 5 of patent US20160206537A1 are also opaque and have a significantly lower foam content than the effect of the examples of the present application. Meanwhile, example 4 uses a large amount of the thickener GLucamate VLT, resulting in excessive viscosity of the product.

Both table 4 and table 5 of patent US20160206537A1 have incorporated pearlescing agents, removed and made up with water, again tested, and it can be seen that the key factor in the generation of opacity is not the addition of pearlescing agents, but the formulation ratio is not suitable for the generation of transparent products.

The preparation methods of the examples and the comparative examples in the invention are as follows: adding the other components except the preservative and the beneficial agent into water, stirring and heating until all the raw materials are uniformly dispersed and transparent; adding an acid-base regulator to regulate pH, cooling, and adding a preservative and a beneficial agent.

Finally, it should be noted that the above description is only for illustrating the technical solution of the present invention, and not for limiting the scope of the present invention, and that the simple modification and equivalent substitution of the technical solution of the present invention can be made by those skilled in the art without departing from the spirit and scope of the technical solution of the present invention.
