Description

Technical Field

[0001] This invention belongs to the field of shampoo technology, specifically relating to a shampoo that can reduce combing force and its preparation process. Background Technology

[0002] Traditional shampoos often add conditioning agents such as dimethicone (silicone oil), which utilize their excellent film-forming, lubricating, and hydrophobic properties to form a smooth protective film on the hair surface, thereby effectively reducing combing resistance and giving the hair a smooth and shiny feel. However, the occlusive nature of silicone oil leads to problems such as deposition, flattening of hair, and affecting the color of dyed hair after long-term use. Therefore, hair care products choose to abandon silicone oil, and "silicone-free" shampoos have become the mainstream trend in the global hair care market over the past decade.

[0003] However, after removing silicone oil, the problem of reduced combing power for wet and dry hair reappears. Excessive combing power for wet hair not only causes pulling pain and tangles during shampooing, but is also one of the main causes of hair damage and breakage.

[0004] Although various alternative treatment options have emerged in the market, they all have limitations to varying degrees:

[0005] Cationic polymers lack a smooth feel, and excessive use may also cause buildup and flatness; oil-based and ester-based conditioners can provide a lubricating feel, but the amount added is limited, and high concentrations are difficult to rinse off, easily resulting in a sticky and oily feeling; protein derivatives can penetrate to damaged areas of the hair shaft, repair the cuticle, and enhance hair strength, but their main function is more "repair" than "instant smoothness," and their direct effect on reducing combing force is limited.

[0006] Therefore, based on market demand, this invention proposes a shampoo with cocoyl hydrolyzed oat protein potassium (KCHOP) as the core, combined with a mild cleansing system and an appropriate amount of thickening and stabilizing ingredients. Summary of the Invention

[0007] To achieve the above objectives, the first aspect of this invention provides a shampoo that reduces combing resistance, the formula comprising the following components: 0.5%-2.5% KCHOP (cocoyl hydrolyzed oat protein potassium), 3.5% cocamidopropyl betaine (CAPB), 2.0% decyl glucoside (APG), 0.15% tea tree oil, 2% cocamidopropyl betaine (CAPB), 0.05% carbomer, 0.3% xanthan gum, 10% sodium citrate, 0.8% phenoxyethanol, 0.3% ethylhexylglycerin, and the balance being deionized water.

[0011] Preferably, the formulation comprises the following components: 2.0% KCHOP (cocoyl hydrolyzed oat protein potassium), 3.5% cocamidopropyl betaine (CAPB), 2.0% decyl glucoside (APG), 0.15% tea tree oil, 2% cocamidopropyl betaine (CAPB), 0.05% carbomer, 0.3% xanthan gum, 10% sodium citrate, 0.8% phenoxyethanol, 0.3% ethylhexylglycerin, and the balance being deionized water.

[0012] Preferably, the formulation comprises the following components: 2.5% KCHOP (cocoyl hydrolyzed oat protein potassium), 3.5% cocamidopropyl betaine (CAPB), 2.0% decyl glucoside (APG), 0.15% tea tree oil, 2% cocamidopropyl betaine (CAPB), 0.05% carbomer, 0.3% xanthan gum, 10% sodium citrate, 0.8% phenoxyethanol, 0.3% ethylhexylglycerin, and the balance being deionized water.

[0013] A second aspect of the present invention provides a shampoo preparation process that reduces combing force, the preparation process comprising the following steps:

[0014] S01 Take 80% of the total amount of deionized water and add it to the reactor. Add 0.3% xanthan gum and 0.05% carbomer, and heat and stir until completely dissolved and transparent.

[0015] Cool SO2 to 45-50℃, add 3.5% CAPB and 1.5% APG in sequence and stir until uniform, then add the specified amount of KCHOP and continue stirring;

[0016] S03. Keep the current temperature, take 0.15% tea tree oil and disperse it with 0.5% APG to prepare an oil phase pre-dispersion. Then add the prepared oil phase pre-dispersion and 2.0% aloe vera extract to the system in sequence and stir for 20 minutes.

[0017] Cool S04 to 35-40℃, add 0.8% phenoxyethanol and 0.3% ethylhexylglycerin, and stir for 15 minutes;

[0019] S06 is cooled to room temperature and left to mature for 24 hours to obtain the finished product.

[0020] Preferably, in step S05, the pH is adjusted using a 10% citric acid solution to 5.3 ± 0.2, which matches the pH of human tears and reduces eye irritation.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention selects potassium cocoyl hydrolyzed oat protein (KCHOP) as the core conditioning ingredient. Through its unique dual structure of "protein hydrophilic end" and "cocoyl lipophilic end", it can be instantly and directionally adsorbed onto the hair strands during the cleansing process. Moreover, this ingredient can effectively repair the hair cuticle and form a thin, breathable, and continuous biomimetic protective film on the hair surface, thereby significantly reducing the combing resistance of wet and dry hair from the source.

[0023] Potassium cocoyl hydrolyzed oat protein (KCHOP), as an anionic surfactant, exhibits excellent compatibility and synergistic effects with other anionic, amphoteric, and nonionic surfactants (such as CAPB and APG) in the formulation. The system is stable, and its molecular structure determines the lightweight and easy-to-rinse properties of its conditioning film. While providing a smooth feel, it reduces the problems caused by the easy deposition of traditional silicone oils and some cationic polymers, which lead to flat hair and affect the color of hair dye.

[0024] Through systematic efficacy verification, the formula containing 2.0% KCHOP achieved the highest scores in key indicators such as non-tangling when wet, smoothness and combability when dry. At this concentration, the product achieves the best balance between improved combing power, user subjective preference and raw material cost, avoiding performance plateaus, rinsing difficulties or unnecessary cost increases caused by excessive addition. Detailed Implementation

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] A shampoo that reduces combability has the following ingredients: 0.5%-2.5% KCHOP (cocoyl hydrolyzed oat protein potassium), 3.5% cocamidopropyl betaine (CAPB), 2.0% decyl glucoside (APG), 0.15% tea tree oil, 2% cocamidopropyl betaine (CAPB), 0.05% carbomer, 0.3% xanthan gum, 10% sodium citrate, 0.8% phenoxyethanol, 0.3% ethylhexylglycerin, and the balance deionized water.

[0028] KCHOP (cocoyl hydrolyzed oat protein potassium) is mainly used as the main surfactant. Its molecular structure is similar to that of skin keratin, which can form a short-term and gentle cleansing film during cleansing, avoiding excessive degreasing. Its cleansing power is controllable and will not completely strip the hair of its natural oils, thus retaining moderate friction and reducing the slippery feeling when combing. Although the hydrolyzed oat protein it contains has affinity, after testing, the amount can be controlled so that it only plays a basic soothing role and does not form a thick smooth film.

[0029] Cocamidopropyl betaine (CAPB), as an amphoteric surfactant, effectively neutralizes and buffers the potential irritation of the main surfactant, improving overall gentleness. The amount used in this embodiment is reduced compared to regular baby shampoo, ensuring no excessive residue after rinsing and leaving hair feeling refreshed. Decyl glucoside (APG), mainly synthesized from plant glucose and coconut oil alcohol, has extremely low irritation to the skin and eyes. It can enhance cleansing power while improving rinsing performance, and moderately increases combing resistance to prevent hair from becoming difficult to style or tangled due to excessive smoothness. Tea tree oil and aloe vera extract are mainly added plant extracts. The oil-soluble nature of tea tree oil requires pre-dispersion with APG to ensure stability in the system. Tea tree oil itself does not have smoothing or film-forming properties. Due to its cooling and astringent properties, it can indirectly bring a refreshing feeling to the scalp, and the appropriate amount of aloe vera extract provides basic moisturizing and soothing effects, avoiding the gel-like feeling and smooth residue caused by high content. It only maintains the necessary moisture of the scalp and does not add extra smoothness to the hair.

[0030] Xanthan gum, as a natural polymer colloid, can make the finished product have a refreshing and non-sticky gel texture. Increasing the amount can improve the viscosity and suspension of the finished product, making the time that the shampoo stays on the hair more controllable and rinsing more thoroughly. 0.05% carbomer can reduce the dripping and overspreading caused by thin emulsions, providing a more obvious texture when applied and reducing the slippery feeling.

[0031] Sodium citrate, in synergy with subsequently added citric acid, precisely stabilizes the final pH value of the product within a slightly acidic range of 5.0-5.5. This pH value helps maintain scalp health, tightens hair cuticles, and keeps hair in a natural state, avoiding the "false slippery" feeling caused by open cuticles and reduced friction due to an alkaline environment.

[0032] Furthermore, phenoxyethanol and ethylhexylglycerin form a preservative and moisturizing system to ensure that the product is not contaminated by microorganisms during use after opening; and deionized water, as a pure base, ensures that all ingredients are fully dissolved and function, and by removing impurity ions, it avoids calcium, magnesium and other ions in the water from affecting the stability of the formula, the cleaning effect or causing unnecessary irritation.

[0033] Based on the above formula, this embodiment also relates to a shampoo preparation process that can reduce combing force, the preparation process including the following steps:

[0034] S01 Take 80% of the total amount of deionized water and add it to the reactor. Add 0.3% xanthan gum and 0.05% carbomer, and heat and stir until completely dissolved and transparent.

[0035] Cool SO2 to 45-50℃, add 3.5% CAPB and 1.5% APG in sequence and stir until uniform, then add the specified amount of KCHOP and continue stirring;

[0036] S03. Keep the current temperature, take 0.15% tea tree oil and disperse it with 0.5% APG to prepare an oil phase pre-dispersion. Then add the prepared oil phase pre-dispersion and 2.0% aloe vera extract to the system in sequence and stir for 20 minutes.

[0037] Cool S04 to 35-40℃, add 0.8% phenoxyethanol and 0.3% ethylhexylglycerin, and stir for 15 minutes;

[0038] S05: Adjust the pH with 10% citric acid solution, add the remaining deionized water to 100%, and homogenize in a homogenizer for 5-10 minutes.

[0039] S06 is cooled to room temperature and left to mature for 24 hours to obtain the finished product.

[0040] Specifically, take approximately 80% of the total amount of deionized water from the formulation and add it to a reactor equipped with stirring and heating functions. Turn on the stirring and slowly and evenly sprinkle in 0.3% xanthan gum and 0.05% carbomer. Then raise the temperature to 75-80℃ and continue stirring at this temperature for 20-30 minutes until the thickener is completely dissolved and the system is uniform, transparent, and free of particles. Cool the above aqueous phase system to 45-50℃; add 3.5% cocamidopropyl betaine (CAPB) and 1.5% decyl glucoside (APG) sequentially, stirring until completely dissolved and the system is clear. Then add 2.0% cocoyl hydrolyzed oat protein potassium (KCHOP) and continue stirring for 15 minutes to ensure that the main surfactant is fully dispersed and blended.

[0041] Maintain the system temperature at 40-45℃. Take 0.15% tea tree oil and 0.5% decyl glucoside (APG) and pre-mix and disperse them evenly to prepare an oil phase pre-dispersion. Then, slowly add the oil phase pre-dispersion and 2.0% aloe vera extract to the reaction vessel in sequence, stirring for 20 minutes to ensure that all components are fully emulsified and dispersed, and the system is stable and homogeneous. Cool the system to 35-40℃. Add 0.8% phenoxyethanol and 0.3% ethylhexylglycerin in sequence, stirring continuously for 15 minutes to completely dissolve and evenly distribute them. Then, use a pre-prepared 10% citric acid solution, slowly adding and stirring, to adjust the pH of the system to 5.3±0.2. Finally, add the remaining deionized water to bring the total weight to 100%.

[0042] The material is then transferred to a homogenizer and homogenized at 2000-3000 rpm for 5-10 minutes to obtain a highly uniform, fine, bubble-free gel system. The homogenized product is then cooled to room temperature and transferred to a clean storage tank for standing and maturing for 24 hours to stabilize the system structure and remove residual bubbles, finally yielding the finished product.

[0095] Subject population selection criteria:

[0096] Gender and age: Female, aged 18-50;

[0097] Hair type and length: Healthy long hair that has not been permed, dyed or bleached and has no obvious split ends; hair type ranges from normal to slightly dry.

[0098] Shampooing frequency: I usually shampoo my hair every 2-3 days;

[0099] Exclusion criteria: severe scalp disease or injury, chemical treatments such as perming, dyeing, or straightening of hair within one month prior to testing, history of allergy to any ingredient in the formula, pregnancy, or breastfeeding.

[0100] Based on the above screening criteria, 20-30 eligible healthy female volunteers were selected and randomly divided into 5 groups. Each group used one type of sample, and a single-group parallel control method was adopted.

[0101] Test location: Constant temperature and humidity laboratory (temperature 22±2°C, relative humidity 50±5%)

[0102] Testing cycle: Adaptation period + formal testing period, totaling 4 weeks.

[0103] Adaptation period (week 1): Distribute a uniform, silicone-free, non-conditioning mild cleansing shampoo (baseline product) to the subjects for home use to standardize their hair quality baseline;

[0104] Formal testing period (weeks 2-4): Test samples are distributed, and subjects use them at home strictly according to the instructions. They return to the laboratory at the end of week 2 and week 4 for instrumental measurements and sensory evaluations.

[0105] Test process:

[0106] The experimenter used the sample being tested on the subject to wash the subject's hair using a uniform technique, for example, using 5g of the sample, massaging for 1 minute, rinsing for 2 minutes, and then using the same type of towel to pat dry the hair until it was no longer dripping.

[0107] Using a combing force tester, take a fixed-width (e.g., 2cm) wet hair bundle from the top, left, and right sides of the head, fix the hair bundle on the instrument, and use a standard comb to comb from the roots to the ends of the hair at a constant speed (e.g., 100mm / s). The instrument automatically records the maximum resistance (gf) and average resistance (gf) during the combing process; repeat 3 times for each part and take the average value.

[0108] Allow the hair to air dry completely in a natural environment. Then, use the same combing force tester to test the same completely dry hair strand and record the maximum and average resistance.

[0109] Participants completed a 5-point questionnaire (1 = strongly disagree, 5 = strongly agree), and the evaluation included: ease of rinsing when wet, degree of tangling, overall smoothness, softness, shine, combability, volume / flatness, and overall preference after drying.

[0112] Data Analysis

[0113] Group D (KCHOP 2.0%) achieved the highest or tied highest scores in the three key dimensions of non-tangling when wet (4.4 points), smoothness when dry (4.6 points), and ease of combing (4.7 points). Although it sacrificed a little bit of volume (3.3 points) and ease of rinsing (3.9 points), it performed outstandingly in the most important smoothness-related indicators and had the best overall preference.

[0114] The conclusions are as follows: wet hair non-tangling, dry hair smoothness, softness, shine, and combability are positively correlated with KCHOP content; easy rinsing and fluffiness are negatively correlated with KCHOP content; when KCHOP reaches 2.0%, most smoothness indicators enter a plateau period, and group E (2.5%) shows no significant improvement compared to group D.

[0115] Therefore, Group D (KCHOP 2.0%) is the optimal formula overall, achieving the best balance between improved combing power, user preference, and cost-effectiveness.

[0116] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
