Description

Transparent amino acid conditioning shampoo

Technical Field

The invention belongs to the technical field of daily chemicals, and particularly relates to transparent amino acid conditioning shampoo and a preparation method of the shampoo composition.

Background

In recent years, as the demand for cosmetics has shifted toward "green", "safe" and "healthy", the functional appeal of shampoos has also shifted from the early cleaning and removing of dirt from hair and scalp to scalp care and hair quality repair, and long-term use of shampoos does not cause damage to or burden on scalp health and hair quality.

The shampoo is mainly composed of a surfactant, a conditioner, a nursing component, a preservative and the like, and the correct selection and the proper application of each component are particularly important. Compared with the traditional sulfate surfactant, the amino acid surfactant is good in biodegradability, green, environment-friendly, safe, mild, low in irritation, good in compatibility with skin and excellent in surface activity, and is increasingly applied to various fields. The conditioner has the main function of nursing hair, so that the hair is smooth, soft and easy to comb. Common conditioners comprise cationic polymers, silicone oils, small molecular esters, light grease, functional additives with different care effects and the like, and the research on how the conditioners are matched with a suitable system is always a key problem in the research of the field of shampoos.

The common cationic polymer conditioner has many unsolved problems in applying the common cationic polymer conditioner to the amino acid surfactant shampoo, is easy to generate floccules, is not easy to stabilize, has opaque system and insufficient conditioning performance, is easy to wind and knot dry and wet combed hair, and has poor hand feeling after being dried. Excessive conditioning will affect the rinsing performance of the shampoo, reduce the amount of foam, be difficult to rub and dry during washing hair, leave residues during rinsing, give a heavy feel to the hair, and the like.

The amino acid preservative is a natural source, is an amino acid cationic surfactant with extremely high stability, has good antistatic and conditioning effects on hair, can soften skin, can improve the smoothness, brightness and glossiness of hair, has safe and strong broad-range bactericidal capability, has effective killing and inhibiting effects on gram-negative bacteria, gram-positive bacteria, mould and saccharomycetes, has good compatibility, can be used as a hair conditioner and a skin conditioner, can be biodegraded, and is environment-friendly.

Chinese patent CN200480012183.3 discloses a cleaning composition comprising (a) a sulfate type anionic surfactant, (B) N-acylalanine or a salt thereof, and at least one compound selected from (C) an amphoteric surfactant, (D) a cationic polymer, (E) a silicone compound, and (F) an oily substance, wherein the mixing ratio of (a) and (B) is (a)/(B) 99/1-70/30 (weight percent), and the concentration of component (a) or (C) is the highest among all surfactant components of the composition. The invention provides a washing composition which takes sulfate surfactant as a main body and contains siloxane compound, and the washing composition is not easy to degrade, opaque, high in irritation, difficult to wash, large in residue, poor in refreshing feeling and not friendly to ecological environment.

Chinese patent CN201610586803.9 discloses a shampoo containing an amino acid surfactant and a preparation method thereof, wherein the shampoo comprises the following components in percentage by mass: 30-60% of anionic surfactant; 0.05 to 3 percent of cationic conditioner; 1% -15% of nonionic surfactant; the balance of water. One or more small molecular alcohols and the like adopted by the invention are known as the moisturizers, but the moisturizers are easy to wash away in the washing process, and cannot fully improve the moist feeling of scalp and hair, reduce the viscosity of the formula and increase the formula cost.

Chinese patent CN201610586803.9 discloses an amino acid shampoo composition and a preparation method thereof, wherein the amino acid shampoo composition comprises the following components by weight percent: 15% -50% of amino acid surfactant; 10 to 30 percent of alpha olefin sodium sulfonate; 10 to 50 percent of betaine surfactant. The surface activity of the amino acid surfactant is enhanced by the compounded alpha olefin sodium sulfonate, the solubilizing compatibility of the cationic conditioner polymer is improved, but the surfactant is strong in degreasing force, high in irritation, dry in skin after use, easy to itch and peel, dry and not bright in hair, non-natural in source and not green and environment-friendly.

PCT patent application WO 2017/106276 Al discloses self-thickening compositions consisting of one or more N-acyl acidic amino acids and/or one of their salts and one or more amphoteric surfactants. The invention mainly solves the problem that glutamic acid and salt systems thereof are difficult to thicken, but the composition has great limitations when being used as shampoo, less foam, dry and astringent flushing, insufficient cleaning force, incomplete washing, more dirt and conditioner residues, easy head itch and easy dandruff generation.
