Description

[0001] This application is a divisional application of the invention patent application with national application number 202180061727.9 entitled “Branched-chain amino acid surfactants for personal care and cosmetic products” filed on March 8, 2023.

[0002] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] This application claims priority to Provisional Application No. 63 / 051,193, filed on July 13, 2020, which is incorporated herein by reference in its entirety. Technical Field

[0004] The present disclosure relates to branched-chain surfactants for use in personal care and cosmetic products. Such branched-chain surfactants may include derivatives of amino acids, wherein the amino acid derivatives have surface active properties. Background Art

[0005] Surfactants (molecules with surface active properties) are widely used in commercial applications in formulations ranging from detergents to hair care products to cosmetics. Compounds with surface active properties are used, among other things, as soaps, detergents, lubricants, wetting agents, foaming agents and spreading agents. In personal care cleaning products (e.g., shampoo, shower gel, face cleanser, hand soap, etc.), surfactants are often the most important component as they provide many of the cleaning properties of the composition.

[0006] Surfactants can be uncharged, zwitterionic, cationic or anionic. Although in principle any surfactant class (e.g., cationic, anionic, nonionic, amphoteric) is suitable for cleaning or cleaning applications, in practice many personal care cleansers and household cleaning products are formulated with a combination of two or more surfactants from two or more surfactant classes.

[0007] Generally, surfactant is an amphiphilic molecule with a relatively water-insoluble hydrophobic "tail" group and a relatively water-soluble hydrophilic "head" group. These compounds can be adsorbed on the interface, such as the interface between two liquids, a liquid and a gas, or a liquid and a solid. In a system comprising a relatively polar and relatively non-polar component, the hydrophobic tail preferentially interacts with one or more relatively non-polar components, while the hydrophilic head preferentially interacts with one or more relatively polar components. In the case of the interface between water and oil, the hydrophilic head group preferentially extends into the water, while the hydrophobic tail preferentially extends into the oil. When added to the water-gas interface, the hydrophilic head group preferentially extends into the water, while the hydrophobic tail preferentially extends into the gas. The presence of surfactant destroys at least a portion of the intermolecular interactions between water molecules, and replaces the interactions between at least a portion of water molecules with the usually weaker interactions between at least a portion of water molecules and the surfactant. This causes the surface tension to reduce, and can also be used for stabilizing the interface.

[0008] At sufficiently high concentrations, surfactants can form aggregates that serve to limit exposure of the hydrophobic tails to polar solvents. One such aggregate is a micelle. In a typical micelle, the molecules are arranged in a sphere with the hydrophobic tails of one or more surfactants preferentially located on the inside of the sphere and the hydrophilic head of one or more surfactants preferentially located on the outside of the micelle, where the head preferentially interacts with the more polar solvent. The effect of a given compound on surface tension and the concentration at which it forms micelles can serve as defining properties of a surfactant. Summary of the invention

[0009] The present disclosure provides personal care products such as shampoo, conditioner, hair dye, hair removal products, cleansers, cosmetics, mascara, denture cleansers and toothpaste. These products can be formulated to include one or more surfactants from one or more surfactant classes disclosed herein.

[0010] The present disclosure provides surfactants for personal care products in the form of amino acid derivatives with surface active properties. The amino acid can be naturally occurring or synthetic amino acids, or they can be obtained via a ring-opening reaction of a molecule such as a lactam (e.g., caprolactam). The amino acid can be functionalized to form a compound with surface active properties. Characteristically, these compounds can have a low critical micelle concentration (CMC) and / or the ability to reduce liquid surface tension.

[0039] I. Definitions

[0040] As used herein, the phrase "within any range using these endpoints" literally means any range that can be selected from any two values ​​listed before the phrase, whether these values ​​are in the lower part of the list or in the upper part of the list. For example, a pair of values ​​can be selected from two lower values, two higher values, or one lower value and one higher value.

[0041] As used herein, the term "alkyl" refers to any saturated carbon chain which may be straight or branched.

[0042] As used herein, the phrase "surface active" means that the relevant compound is capable of reducing the surface tension of the medium in which it is at least partially dissolved, and / or the interfacial tension with other phases, and can therefore be at least partially adsorbed at liquid / vapor and / or other interfaces. The term "surfactant" can be applied to such compounds.

[0043] With respect to imprecise terms, the terms "approximately" and "substantially" are used interchangeably to refer to a measurement that includes the stated measurement and also includes any measurement that is reasonably close to the stated measurement. As understood and readily determined by one of ordinary skill in the relevant art, a measurement that is reasonably close to the stated measurement differs from the stated measurement by a relatively small amount. For example, such deviations may be due to measurement error or minor adjustments made to optimize performance. In the event that a value is determined that is not readily determined by one of ordinary skill in the relevant art, the terms "approximately" and "substantially" may be understood to refer to plus or minus 10% of the stated value.

[0276] These surfactants can be synthesized by various methods. One such method includes opening a lactam to produce an amino acid with an N-terminal and a C-terminal. The N-terminal can react with one or more alkylating agents and / or acids to produce a quaternary ammonium salt. Alternatively, the N-terminal can react with an oxidant to produce an amine N-oxide. The C-terminal can react with an alcohol in the presence of an acid to produce an ester.

[0277] The amino acid may be naturally occurring or synthetic, or may be derived from the ring opening reaction of a lactam such as caprolactam. The ring opening reaction may be an acid or base catalyzed reaction, and an example of an acid catalyzed reaction is shown in Scheme 1 below.

The alkyl chain may be further substituted by one or more substituents selected from hydroxyl, amino, amide, sulfonyl, sulfonate, carboxyl and carboxylate. The N-terminal nitrogen may be acylated or alkylated with one or more alkyl groups. For example, the amino acid may be 6-(dimethylamino)caproic acid or 6-aminocaproic acid.

[0301]

[0302] Compounds of the present disclosure exhibit surface active properties. These properties can be measured and described by various methods. One method by which surfactants can be described is by the critical micelle concentration (CMC) of the molecule. The CMC can be defined as the concentration of the surfactant when micelles are formed, and above this concentration all additional surfactants are incorporated into the micelles.

[0303] As the surfactant concentration increases, the surface tension decreases. Once the surface is completely covered with surfactant molecules, micelles begin to form. This point represents the CMC and the minimum surface tension. Further addition of surfactant will not further affect the surface tension. Therefore, the CMC can be measured by observing the change in surface tension as a function of surfactant concentration. One such method to measure this value is the Wilhelmy hanging plate method. The Wilhelmy plate is usually a thin iridium-platinum plate that is connected to a balance by a wire and placed perpendicular to the air-liquid interface. The balance is used to measure the force applied to the plate by wetting. This value is then used to calculate the surface tension (γ) according to equation 1:

[0304] Equation 1: γ = F / l cosθ

[0305] where l is equal to the wetted perimeter (2w+2d, where w and d are the thickness and width of the plate, respectively), and cosθ is the contact angle between the liquid and the plate, which was assumed to be 0 in the absence of existing literature values.

[0306] Another parameter used to evaluate the performance of surfactants is the dynamic surface tension. Dynamic surface tension is the value of surface tension for a specific surface or interface lifetime. In the case of a liquid to which a surfactant is added, this may be different from the equilibrium value. Just after the surface is created, the surface tension is equal to that of the pure liquid. As mentioned above, surfactants reduce the surface tension; therefore, the surface tension decreases until the equilibrium value is reached. The time required to reach equilibrium depends on the diffusion rate and adsorption rate of the surfactant.

[0307] One method for measuring dynamic surface tension relies on a bubble pressure tensiometer. This device measures the maximum internal pressure of a bubble formed in a liquid via a capillary tube. The measured value corresponds to the surface tension at a certain surface lifetime (the time from the start of bubble formation to the occurrence of the pressure maximum). The dependence of the surface tension on the surface lifetime can be measured by varying the speed at which the bubbles are generated.

[0308] Surface active compounds can also be evaluated by their wetting ability on solid substrates (as measured by contact angle). When a droplet comes into contact with a solid surface in a third medium (such as air), a triple line is formed between the liquid, the gas and the solid. The angle between the surface tension unit vector acting on the triple line and tangent to the droplet and the surface is described as the contact angle. The contact angle (also referred to as the wetting angle) is a measure of the wettability of a liquid to a solid. In the case of complete wetting, the liquid is completely spread on the solid and the contact angle is 0 °. The wetting properties of a given compound are usually measured at a concentration of 1-10×CMC, but it is not a concentration-dependent property, so the measurement of the wetting properties can be measured at higher or smaller concentrations.

[0309] In one method, contact angles can be measured using an optical contact angle goniometer. This device uses a digital camera and software to analyze the contour shape of a sessile droplet on a surface to derive the contact angle.

[0310] Potential applications for the surface-active compounds of the present disclosure include formulations for use as shampoos, conditioners, detergents, spot-free rinses, floor and carpet cleaners, cleaners for graffiti removal, wetting agents for crop protection, adjuvants for crop protection, and wetting agents for aerosol sprays.

[0311] Those skilled in the art will appreciate that small differences between compounds can result in significantly different surfactant properties, allowing different compounds to be used in different applications with different substrates.

[0312] The following non-limiting embodiments are provided to demonstrate the different properties of different surfactants. In Table 1 below, the abbreviations of the surfactants are associated with their corresponding chemical structures.

These surfactants are useful in the above applications and some other special applications, such as surface treatments, such as personal hair care products, and can also be used to create water repellent surfaces.

[0318] Surfactant 4 is zwitterionic. These surfactants can be used as co-surfactants in all the above applications.

[0319] Surfactant 5 is nonionic and can be used in shampoos, detergents, hard surface cleaners and a variety of other surface cleaning formulations.
