CN113088406A - Composite surfactant with pearlescent effect - Google Patents

Abstract

The invention discloses a composite surfactant which is applicable to daily washing products or cosmetics and can provide obvious pearlescent effect, and the composite surfactant comprises the following raw materials: deionized water, ethylene glycol distearate, ethylene glycol monostearate, fatty alcohol-polyoxyethylene ether sodium sulfate, fatty alcohol-polyoxyethylene ether and phenoxyethanol. The key point of the product is that the monoester and the diester are accurately proportioned, and the product can present the most beautiful effect in various final product systems added with the product. Meanwhile, a scheme of compounding universal anionic surfactants and nonionic surfactants is adopted, so that the problem that the pearlescent flakes cannot be directly dissolved in water is solved, and a scheme of directly compounding surfactants in a cleaning product is provided. For some small-scale factories without research and development capability, the product can be directly dissolved in water and flavored, and then can be sold as a finished product. The product has good compatibility and stability for cosmetics requiring complex processes and high-end cleaning.

Description

Composite surfactant with pearlescent effect

Technical Field

The invention belongs to the technical field of surfactants, and mainly relates to a composite surfactant with a pearlescent effect

Background

Most of the existing single surfactants can not be directly used as detergents, and the use of only a single surfactant as a detergent or a cleaning cosmetic can cause incomplete cleaning, high skin irritation, incapability of coping with complex stains, incapability of adapting to hard water, complex skin surface environments, different pH values and the like. Therefore, most of the finished cleaning agents/cleaning cosmetics on the market adopt the composite surfactant to be suitable for different stains, different pH systems and different use environments. For example, if the laundry detergent needs an alkaline environment, the surfactant which can not be used in the alkaline environment can not be used, and the water quality faced by the laundry detergent is likely to be relatively hard, so that hard water resistance is also very important; the products such as the bath lotion and the facial cleanser need to directly act on the skin, the system is neutral or weakly acidic in order to ensure that the irritation to the skin is very small, and the facial cleanser directly acts on the face without being added into water for dilution, so that the hard water resistance is not as important as that of a laundry detergent. Furthermore, many products require the addition of special substances to the body of the product in order to be better marketable, so that the product assumes a more advanced state.

Disclosure of Invention

The invention aims to provide a composite surfactant with a pearly-lustre effect, which can be directly used in detergent products and can also be used in cosmetics through other compounding, so that the high-grade feeling of the pearly-lustre products is provided, and the blending process of the pearly-lustre products is simplified. The compound surfactant with the pearlescent effect is a product prepared by independently adding deionized water, a spice and a preservative or a product prepared by compounding the compound surfactant with other special functional surfactants, has rich foam, less residue after washing, low skin irritation and good pearlescent effect, has the unique defect of adopting AES as a surfactant compound, so that the cleaning capability is possibly reduced under the condition that the pH is less than 5, and the inevitable defect of ensuring the compatibility, stability and universality of the product is also the defect, so the product is recommended to be used in the pH range of 5.5-10 and is recommended to be used in laundry detergents, liquid detergents, shower gels, facial cleansers and hand washing liquids. It is necessary that the system acidity not be too strong.

A composite surfactant suitable for daily washing products or cosmetics and capable of providing obvious pearl effect is prepared by the following steps:

s1, adding deionized water into the pot;

s2, adding AES and AEO-9, heating to 40 ℃, and stirring until the AES and AEO-9 are completely dissolved;

s3, stirring at 30rpm for 30 min;

s4, heating to 65 ℃, and keeping stirring;

and S5, gradually adding the monoester pearling agent and the diester pearling agent in the process, keeping the viscosity not to rise too fast, observing in a blending pot by naked eyes, and adding the next batch after the pearling agent is about to be completely dissolved until the addition is completed. It should be noted here that when the temperature of the system is between 45 ℃ and 53 ℃, if too many pearly-lustre sheets are added at a time, the viscosity of the system becomes very high in a short time, which seriously affects the stirring of the stirring paddle and the overall heating, and if electric heating is adopted, too high local temperature may be caused to generate various uncontrollable problems. A steam jacket is used for heating to ensure uniform heating, and the pearlescent sheets are gradually added after the temperature is raised to 45 ℃, so that the state of the pearlescent sheets which are dissolved immediately after entering water is ensured, and the stirring paddle is blocked without overhigh viscosity increase;

s6, continuously stirring to ensure that the pearling agent is completely melted and dissolved in a surface activity system, wherein the stirring speed in the process is lowered, and only the liquid fluidity is ensured by matching with the increase of viscosity and the increase of temperature, and the stirring lasts for about 30 min;

and S7, adding phenoxyethanol and continuously stirring.
