Description

Skin-protecting phosphorus-free washing powder

The present invention relates to a kind ofly promptly conserve natural habitats, again people's skin is not had the non-phosphide detergent of injury.Synthetic detergent, since nineteen forty-six scale operation replaced soap market, production had been passed through auxiliary agent and has been contained the leap (sudden change) of phosphatization to big twice of no phosphatization.We can say that the development history of synthetic detergent is the history that a Personal hygiene and public health are mutually promoted.

In recent years, brainstrust appeals that generally it is poor more to wash sanitary condition more.People only pay attention to detergency power of laundry powder, have but ignored washing powder and have included the injury to the people in laundry, the process of wearing the clothes of harmful mineral substance.Now on the China market, all generally use sodium phosphate as washing assistant based on many articless for washing of washing powder.On the surface, our clothes has been a wash clean, but if in fact from protecting the angle of HUMAN HEALTH, if the phosphorous washing powder of secular use, our healthy can more and more be encroached on, and sanitary condition worse and worse.

Because common washing powder has direct stimulation to skin, housewife hand and arm when laundry can produce the sensation of living calcination pain, and wash back drying in the sun clothes and usually put on again and make people's itch hard to bear.It is reported the Guangzhou preventing and treating skin diseases among the annual average 100,000 person-times outpatient, have 5% approximately because of using common washing powder to go to a doctor.There is the expert simply directly to exhale, " potential " killer of sanitising agent---HUMAN HEALTH "; various energy-saving convenient multifunctional novel washing powder, cleaning agent for kitchen, cleaning agent; air freshener constantly comes out, and is called " domestic sort of eczema " and dermopathic sickness rate also be the trend of obvious increase.Medically generally be referred to as the palm and refer to seborrheic keratosis.Now Dermatology Department to be that the women seeks medical advice many, go to a doctor most likely for this reason.The expert points out that this illness is multiple ascendant trend, and with urban life in a large amount of use direct relations of various chemical industry synthesis of detergent cleaning supplies, their also are simultaneously contact dermatitis, baby diaper, the stimulus of common skin diseases.Therefore avoiding washing powder is essential to people's injury with to ecological balance damage.

Not only the people's goes to bits, and the water that the human life depends on for existence is also by phosphorated washes severe contamination, cause rivers and lakes water body " eutrophication ", generate a large amount of algae, causing current to slow down water oxygen level descends, fish and other hydrobiont hypoxia deaths, red tide is on the point of numerous, causes water quality to degenerate even smelly.Human lives's water system vicious cycleization will cause living environment to be destroyed.The imbalance of phosphorus will shake the animals and plants ecological balance damage, and this does harm to doubts.After now the somebody recognizes western developed country limit phosphorus and prohibits phosphorus curiously, phosphorus content does not descend in the water, and this is unusual shortsighted view so oppose to prohibit phosphorus by limit phosphorus.Because the phosphorus of the pollution in the water is not moved to fall and removes, phosphorus landlocked and soil also can flow in the water continuously, and relates to the problem of the comprehensive regulation, does not almost have the expert of country to oppose to limit phosphorus and prohibited phosphorus now.Therefore, the angle of taking all factors into consideration from public health and Personal hygiene has been invented this product.External existing skin mild washing composition such as JP9627481, WO9601306, these inventions mainly are by selecting for use the expensive tensio-active agent to the skin gentleness to realize.This is not suitable for China's national situation.We use enepidermic toxicity control principle and estimate principle by a large amount of formulation screening tests, test in a large number, have finished the present invention.

(1), by kinds of surface promoting agent compatibility, improve comprehensive detersive power, the HLB value scope of enlarged surface promoting agent, among the present invention kinds of surfactants be no less than 4 kinds, by tensio-active agent synergy raising detersive power.

(2), adopt can attract dirt auxiliary agent, make dirt effectively break away from fabric and washes.White carbon black, HPMC, PVP, PVA, pregelatinized Starch, α starch, beta-cyclodextrin, starch to the absorption combination of oiliness water-based soils, and derive from amylodextrin and the Mierocrystalline cellulose of plant, its toxicity is little, biological degradability is strong, has replaced the stimulation of high density soda ash, Sodium sulfate anhydrous.min(99) and sodium phosphate, effectively reduces pungency.

(3), it is generally acknowledged and wash 10 times of rinsing waters and residual washing powder could be removed for four times that this is difficult to accomplish concerning common people to washes.According to the rinsing equation: $\frac{\mathrm{Xo}}{\mathrm{Xa}}={\left(\frac{b}{a+b}\right)}^n$

Thus, residual is absolute.Residue on the underwear 24 hours and skin contact, especially many, when perspiring or drenching with rain at secretory product, more obvious to the injury of human skin.So it is necessary seeking a kind of washing powder to people's safety.

(4), the human safety evaluation test, bring injury for people's health for making washing powder, become real sanitary product.How to exempt to keep away the injury of synthetic detergent, the toxicity of just necessary employing science objective appraisal washing powder to the people.Past people is only with LD ₅₀Weigh toxicity, in fact this is irrational.Washing powder produces in the laundry and two links of wearing the clothes people's injury.Toxicity in these two links is direct object with skin all, does not have acute lethal toxicity (LD ₅₀).Therefore with estimating externally applied medicine the irritation test of skin is estimated the toxicity of washing powder, or compare reasonably.Adopt which type of animal simultaneously, the concentration of washing powder is all influential.The expert of Hebei Medical University tests according to enepidermic safety evaluation.The result be skin care type washing powder to the skin nonirritant, the pungency integration is 0 (＜0.5).

(5), fiber pervasion agent, at the dirt in the microtubule deep of crosslinked deep of fiber and natural fiber, general washings needs to adopt HLB value tensio-active agent between 1-3 because surface tension can not be goed deep into more greatly, washings is moistening to the depths, dirt is thoroughly removed.So use an amount of fiber penetration enhancer, not only can reduce surface-active consumption, can also improve detersive power.

(6), the application of biological enzyme, use Sumizyme MP, lipase, heavy dirt is decomposed, can play the raising detersive power, reduce dosage of surfactant, reduce toxic effect.

(7), adopt slow controlled-release technology, fragrance remaining time is prolonged, improved clothing and people's relation, add freshener simultaneously, making wears the clothes feels to become salubrious, comfortable, all these is the develop characteristics of following washing powder.
