Abstract

Washing paste based on alkaline dithionites, inert filler and detergent, composed by weight of 250-400 parts of inert filler with a grain size of < 0.1 mm, 200-400 parts of alkaline dithionite, 300-600 parts of glycerol, 50-200 parts of detergent not containing sulfur groups, preferably based on ethoxylated fatty alcohols of the general formula R-0/C2H^/nH, where R · alkyl C,2 - C)8, n = 3-4, 150-300 parts of an alkaline salt, preferably sodium carbonate, 20-50 parts of an antioxidant, preferably powdered Fe with a grain size of 0.1-0.05 mm.

Description

The present invention relates to a novel nourishing paste with a strong discolouring effect on thick soiled skin.

The detergents (pastes) which have been bleached and known to date are generally based on sulphoxide, resp. formaldehyde sulfoxylate as the active ingredient for decolorizing organic dyes. These imported pastes leave the skin dry or wrinkled, often with an unpleasant astringent feeling.

Said disadvantages are eliminated by washing paste with a strong discolouring effect on heavily soiled hand skin, based on alkaline dithionicides, utilizing their known reducing effect, inert filler and detergent. The washing paste comprises the present invention

250-400 wt. parts of an inert mineral filler with a particle size of 0.1 (according to a sieve analysis),

200-400 wt. parts of alkaline dithionite,

300-600 wt. parts of glycerol,

50-200 wt. parts of a non-sulfur-containing detergent, preferably based on ethoxylated fatty alcohols of the formula RO / CgH4O / JH, wherein R = alkyl ^C 12 ^-C 18 ' ⁿ ' ³ >

150-300 wt. parts of the alkali salt, preferably sodium carbonate,

20-50 wt. parts of the antioxidant, preferably powdered iron with a grain size

0.1-0.05 mm (according to sieve analysis).

The washing paste according to the invention may optionally contain 10-40 wt. parts of the flavoring agent, preferably of a terpenic nature.

SUMMARY OF THE INVENTION The present invention is based on a suitable combination of the abovementioned substances, wherein the active decolorizing component is an alkali dithionite. The vanalizate formulation has a strong discolouring, degreasing and cleansing effect; its economic advantage is its composition of exclusively domestic raw materials.

The paste according to the invention is suitable for workers in chemical, especially dyeing, textile, textile-chemical, metallurgical, engineering and other operations and laboratories, and also for manual workers in public services such as handymen, locksmiths, plumbers, car mechanics, laundries, cleaning, hairdressers and under.

Example 1

360 wt. parts of ground feldspar, 320 wt. parts by weight of sodium dithionite, 500 wt. parts by weight of glycerol, 150 wt. parts of turpentine soap, 230 wt. parts of sodium carbonate kale. and 50 wt. The paste obtained has a good decolorizing and de-creasing effect.

Example 2 -

400 wt. parts of ground fluorspar, 350 wt. parts by weight of sodium dithionite, 400 parts by weight, parts by weight of glycerol, 150 parts by weight; 250 parts by weight of ethoxylated lauryl alcohol of the formula G HHg ^OO / CgH ^O /H, 250 wt. 50 parts by weight of sodium carbonate; parts of Fe powder and 20 wt. parts of terpenic emission after melting rosin. The paste obtained has a very good bleach and odmail effect.

Example 3

360 wt. parts of ground feldspar, 320 wt. parts by weight of sodium dithionite, 400 wt. parts by weight of glycerol, 100 wt. parts by weight of ethoxylated p-octylphenol of formula ^C 8 ^H 17 ^-C 6 ^H 4 ^-O ( ^C 6 ^H 4 ^O ) 4 H, 250 wt. 50 parts by weight of sodium carbonate; parts of Fe powder and 30 wt. parts of the terpenic mixture after melting the rosin. The paste obtained has a very good bleaching and degreasing effect.

Example 4

360 wt. parts of ground feldspar, 320 wt. parts by weight of dithionite, 400 wt. parts by weight of glycerol, 100 wt. parts by weight of ethoxylated β-octylphenol of the formula C 8 H 8 · C 9 H 4 O / C 8 H 4 O / gH, 250 wt. 50 parts by weight of sodium carbonate; parts of Fe powder and 40 wt. parts σ <-filled. The paste obtained has a very good bleaching and degreasing effect.
