Description

(54) Solid, pasty and liquid detergent and cleaning agent

The invention relates to a solid, pasty or liquid skin-cleaning detergent and cleaning agent, in particular various types of toilet, mixed synthetic soaps, washing pastes and solutions and detergents and solid surfactant-based surfaces or mixtures thereof, characterized in that contain tea leaf extract. The addition of the extract results in dermatological skin-beneficial substances being introduced into the composition, thereby reducing skin irritation caused by contact with surfactants.

BACKGROUND OF THE INVENTION The present invention relates to a skin, pasty or liquid skin cleansing and cleaning composition comprising both alkali salts of fatty acids and synthetic surfactants, or combinations thereof, together with other filler, activator, fragrance and other ingredients with a dermatologically beneficial ingredient. acting mixtures of substances consisting of caffeine, theamine, flavonoids, catechins and other compounds, obtained by alcoholic extraction of tea leaves (Tea sinensis, Camelia japonica).

Despite all speculative assumptions, detergents based on alkaline fatty acid salts remain the dominant skin cleanser. Although their non-toxic and disproportionately milder skin effects show better dermatological results than synthetic surfactant cleaners, they cannot be said to have no effect on the skin at all. Their alkaline reaction causes it to swell, alkalinize and degrease. These negative effects have been accentuated with the recent increase in hygiene and prophylactic practices. In the case of detergents which come into contact with the skin based on synthetic surfactants, the action on the skin is considerably more aggressive, especially in the area of degreasing and irritation.

One way to eliminate these negative effects is to add dermatologically beneficial ingredients that eliminate or at least significantly suppress the aforementioned properties. The compositions known to date have a dermatological effect and contain various kinds of ingredients which differ in composition and effect. For example, USSR 324,379 (1978) Hygiene Detergent has the use of a 3 to 4% by weight chlorophylllocarotene paste in the Hygiene Detergent formula. This paste is not specified in detail in terms of composition, dry matter content, method and technology of obtaining from the feedstock.

In the description of the invention to U.S. Pat. No. 224 329 is the use of an extract obtained from the needles of forest trees, the active ingredient of which are mainly carotenoids, chlorophyll and vitamin C.

The present invention relates to solid, pasty or liquid skin cleansing and cleaning compositions, in particular various types of toilet, mixed synthetic soaps, washing pastes, dishwashing solutions and detergents and solid surfactant-based surfaces or mixtures thereof with other fillers, activating, fragrant and other components, characterized in that they contain from 0.05 to 10% by weight of the leaves of the tea plant by extraction with water or a low aliphatic alcohol, preferably ethanol. The dermatologically active ingredient of these extracts is caffeine, theamine, various flavonoids (guercetin), catechins (d, 1-catechin) and other compounds.

The tea is extracted with water or ethanol for at least 24 hours. The extract thus obtained, which contains 1.5 to 6% by weight of dry matter, is stabilized mostly with ethanol, sodium bisulfite or dried under vacuum. In the latter manner, tea extract can be obtained in powder form having up to 100% by weight of dry matter. This powder extract is well soluble in water. The addition of the aqueous, alcoholic or dried powder extracts thus obtained ensures that dermatologically beneficial substances such as caffeine, theamine, various flavonoids, catechins and other compounds are introduced into the detergent and cleaning compositions according to the invention to the maximum extent possible.

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention in any way.

He did

By conventional technological process of continuous production of toilet soaps, 95.895 wt. soap containing 79 wt. % of the fatty acids added by the dosing device a mixture containing 0.2 wt. % titanium dioxide, 1.0 wt. % water, 0.005 wt. dye, 2 wt. perfume,

0.5 wt. lanolin and 0.4 wt. powdered tea extract. The soap produced has a lower irritation coefficient of 6 units compared to soap of the same composition not containing the extract.

Example 2

Synthetic soap containing 60 wt. % sodium lauryl sulfate, 20 wt. % palmitic acid, 10 wt. % waxes, 5 wt. % lauric monoethanolamide, 2 wt. % perfume, 0.5 wt. % dye and 2.5 wt. % aqueous tea extract containing 2.5 wt. the dry matter is produced by a conventional batch process of soap production. In subjective evaluation of the washing sensation, 95% of the evaluators reported a more pleasant washing sensation and a lesser feeling of dryness on the extract soap than on the same extract without soap. The irritation factor for extract soap is 10 units lower.

Example 3

Liquid detergent is prepared at 70 ° C by mixing 15 wt. % sodium lauryltriglycol ether sulphate, 10 wt. % sodium lauryl sulfate, 7 wt. % triethanolamine salts of sodium dodecylbenzenesulfonate, 5 wt. % disodium ethylenediaminetetraacetic acid, 0.5 wt. % monoammonium salts of phosphorylated diglyceride diglyceride, 61.5 wt. water and 1 wt. powdered tea extract. Detergent is intended for hand washing of dishes and hand washing of delicate laundry. The irritation factor of the detergent with the extract is 5 units lower than that of the detergent without the extract.

Example 4

When preparing hand wash paste, 26% by weight is thoroughly mixed. wood flour, 18% by weight water, 10 wt. % sulfated adduct of lauryl alcohol with ethylene oxide, 8 wt. 3% wt. bentonite, 30 wt. % kaolin and 5 wt. % aqueous tea extract having a dry matter content of 1.8% by weight; The hand paste with extract has 6 units lower irritation factor than the paste of the same composition without the extract.

Claims (1)
