- Figures 8 and 9 are graphs showing the evolution of enzymatic activity of various liquid detergent compositions, as a function of time.
- the measured absorbance makes it possible to deduce the concentration of hydrolysis product of the substrate (Beer-Lambert law), and the variation of absorbance ⁇ A / min is proportional to the activity of the enzyme in question.
- the alkylpolyglucosides (abbreviated as APG) are compounds of general formula:
- RO - (G) x where R is a linear or branched alkyl chain, and G is a monosaccharide such as glucose.
- R is a linear or branched alkyl chain
- G is a monosaccharide such as glucose.
- APGs are C8 to C16 fatty alcohols glucosides (hereinafter referred to as C8-C18 glucoside) such as cocoglucoside and C12 to C16 glucoside fatty alcohols (hereinafter referred to as C12-C18 glucoside) such as laurylglucoside.

- Antifungal activity [0036] Antifungal activity tests were carried out according to the following procedure:
- a composition according to the invention contains the following components:
- glycol ether dipropylene glycol monomethyl ether
- This composition is particularly suitable for eliminating and preventing the appearance of molds, for example in bathrooms. Operating mode:
- test of the anti-fungal activity is carried out on the basis of the anti-biogram technique: a rich culture medium is inoculated with the aid of microorganisms on which it is desired that the product act:
- Figure 2a shows the development of the mold culture after 24 hours on an untreated support.
- Figure 2b shows the same result, with the composition above.
- Figures 2c and 2d show this development after 48 hours.
- the mold begins to grow on the petri dish where no product has been added.
- the mold continues to grow strongly on the inoculated medium where no product has been deposited.
- the composition according to the invention was added. Nevertheless, some microorganisms develop around the inhibition halo formed by the addition of the product.
- composition of the invention therefore has anti-fungal properties because it prevents fungi from developing for a certain period.
- This product is to be used regularly if it is desired to use it as a preventive treatment.
- a complementary study has demonstrated the action of both enzymes and essential oils on limiting the growth of the fungus. Each active substance is therefore of interest.
- compositions according to the invention comprising an APG, an essential oil, a glycol ether, and an enzyme have unexpected interesting characteristics.
- APG an essential oil
- glycol ether an enzyme
- test compositions were compared. The following tests were carried out with the following compositions:
- Product A contains an essential oil and APG (a C8-C16 glucoside), but no enzyme.
- the essential oils are the essential oils of thymus vulgaris, cymbopogon martinii, citrus limonum (0.1%).
- Product B conversely, contains an enzyme, but no essential oil, and the same APG (a C8-C16 glucoside).
- Enzymes are alpha-amylase, an enzyme complex of ⁇ -glucanase, cellulase, hemicellulase, arabanase and xylanase, carbohydrase, lysophospholipase and phospholipase (0.2%)
- a composition according to the invention containing an APG, an essential oil and an enzyme.
- APG is a C8-C16 glucoside
- the oil essential is a blend of essential oils of thymus vulgaris, cymbopogon martinii and citrus limonum (0.1%),
- composition according to the invention containing an APG, an essential oil and an enzyme.
- APG is a C8-C16 glucoside
- the essential oil is a blend of essential oils of citrus limonum and citrus aurantium L. ssp. bergamia (0.1%) (essential oils obtained from citrus fruits).
- a volume of 200 .mu.l of each product is poured onto a mold transplanted on petri dishes in a rich medium.
- the inoculum on petri dishes is prepared from a piece of agar already contaminated with mold.
- Petri dishes are incubated at 35 0 C for 72 hours and compared to a blank.
- the following results are observed: [0038]
- a first series of tests aims at evaluating the antifungal effect of each of the components of the compositions according to the invention.
- Products A, B, C and D, described above, are compared.
- Figure 3a shows the state of development of the mold at the initial time.
- Figure 3b shows the state of development of the mold after 24 hours. It is observed that the mycelium of the mold begins to extend circularly from where the contaminant was deposited. In the box where compositions A and B have been applied, no mold growth is observed.
- Figure 3c shows the state of development of the mold after 48 hours. After 48 hours of incubation, white mold tripled its coverage area from the initial inoculation location. Some points of mold development are to be noted for the product A, containing an essential oil and the product B, containing an enzyme, but this development is limited.
- Figure 3c shows the state of development of the mold after 72 hours. After 72 hours of incubation, the mycelium constituting the mold of white has further spread. The mold spots for product A and B have grown but the amount of mycelium to white is limited. In addition, mold does not develop from the point of inoculation (at center) but rather from the periphery, which indicates the presence of an inhibition zone triggered by the antifungal activity of the two products A and B.
- a second series of tests aims at evaluating the effect antifungal of each two types essential oils used in compositions according to the invention and compares the compositions C and D and the "white”.
- Figure 4a shows the state of development of the mold at the initial time.
- Figure 4b shows the state of development of the mold after 24 hours. After 24 hours of incubation, the mold begins to develop for the white. There is no development for petri dishes containing compositions C and D.
- Figure 4c shows the state of development of the mold after 48 hours of incubation.
- the mycelium contained in the white has grown considerably. We begin to see a slight development of mold for compositions C and D but this development is much less pronounced than for white. This less significant development is indicative of the antifungal activity of compositions C and D.
- Figure 4d shows the state of development of mold after one week of incubation. After a week, the mycelium of mold completely filled the entire surface of the control. The surface of the media where compositions C and D have been deposited is still not completely covered.
- the development of mold is less pronounced in the composition C than in the composition D. This is quite normal because the essential oils based on herbs (clove, palmarosa.etc.) Are recognized for their power.
- the citrus-based essential oils have a lower bactericidal and anti-fungal potency. It is concluded from these tests, on the one hand, that the enzymes and essential oils (derived from aromatics) each have antifungal activity. These two types of renewable raw materials can therefore work in synergy because they have different modes of action on microorganisms. These results highlight an antifungal effect of enzymes used in the formulations of the invention. Then, the choice of the essential oil mixture determines the effectiveness of the anti-fungal activity in the more or less long term.
- compositions of the invention taken in isolation, by comparing them to a usual product.
- the experiment involves coating a glass cup with a fixed amount of red colored butter. The product to be tested is brought into contact with the cup, without agitation, in order to check the degreasing efficiency of the formula.
- the solvents having the most important degreasing power, among the range of solvents tested are the essential oils terpenes of orange and lemon, propylene glycol ethers (propylene glycol monomethyl ether and dipropylene glycol monomethyl ether).
- compositions according to the invention thus combine the short-term degreasing effect of solvents with the longer-term degreasing effect of C8-C16 glucosides.
- compositions according to the invention comprising an alkylpolyglucoside, an essential oil, a glycol ether and an enzyme with respect to the two classes of known products of the prior art.
- the experiment consists in coating a glass dish with a fixed and known quantity of colored butter in red.
- the test composition is brought into contact with the cup, without stirring, in order to verify the effectiveness of the formula.
- 50 ml of a 10% solution of the test composition are poured into the dish, the mixture is left to act for 40 minutes at room temperature, then the mixture is heated at 105 ° C. for 20 minutes to remove all traces of water, and weighs to determine the amount of colored butter removed.
- compositions according to the invention are compared with products of the first class, the product "Reatout” of the applicant, and a formulation representative of this class of products, and products of the second class, the "Soft” product of the applicant, and a representative formulation of this other class of products.
- the compositions of Reatout and Soft products are as follows:
- compositions of the representative products of the first and second classes are as follows:
- Figure 6 shows the evolution after 1 hour of soaking. It can be seen that the composition according to the invention MPR5 (FIG. 6 a) is more effective in degreasing power than products of the class 1 market (FIG. 6b) and 2 (FIG. 6c). This improvement in the degreasing power of a composition according to the invention can be explained by the synergy of the action of the enzymes (lipase) and the other components of the product (C8-C16 glucoside, glycol ether, essential oils).
- the enzymes lipase
- compositions according to the invention that can be used in spray form, that is to say a composition which is strongly diluted with water, comprising an alkylpolyglucoside, an essential oil. , a glycol ether and an enzyme.
- the effectiveness of this composition is compared with that of a spray cleaning formulation multi-purpose representative of what exists on the market.
- the compositions of these two formulations and their effectiveness, determined as being the percentage by weight of colored butter removed, are detailed in the table below:
- the test is also carried out in glass cups coated with a thin layer of colored butter using a red dye. A quantity of 0.5 g of butter per cup is spread evenly over the entire surface.
- the Test compositions are contacted with the cups, without agitation, in order to verify the effectiveness of the formula. 50 ml of a pure solution of each test composition are poured into the cup. This efficiency test is performed without mechanical action and at room temperature. The results are observed after 40 minutes (see Figure 7). From the first minutes, the spray according to the invention (FIG. 7b) attacks the fat while the product of the market (FIG. 7a) hardly acts.
- the spray according to the invention emulsifies the fat much better than the product of the market.
- the pH variation, before and after action of the product, for the composition according to the invention is 0.27, whereas it is zero for the product of the market.
- the emulsion obtained with the spray according to the invention was therefore acidified. This indicates that the lipases contained in the formulation acted well on the triglycerides by converting a portion of the fat into fatty acids, resulting in the acidification of the mixture.
- the new spray according to the invention based on MPR, has improved properties compared to products on the market. Thanks to its powerful synergistic natural elements (C8-C16 glucoside, orange terpene, lipase), it manages to tackle fat efficiently and quickly
- FIG. 8 represents the evolution of the enzymatic activities of the compositions according to the invention MPRF1 to MPRF6, and of a conventional enzymatic composition, without MPR, the product "Degrees L" of the Applicant. It is found that in all cases, the enzymatic activity of the compositions according to the invention is greater than that of the composition "Degrees L".
- the stability of the enzyme has also been tested in various formulations listed in the table below.
- MPR1 contains no essential oil or glycol ether. In MPR2, a glycol ether was added: dipropylene glycol monomethyl ether. In MPR3, a terpene is present, but no glycol ether. In MPR4, there is no MPR.
- MPR5 is a composition according to the invention.
- MPR6 is comparable to MPR1, but the surfactant is a commercial product from the petrochemical industry.
- MPR7 contains a glycol ether and an enzyme.
- Figure 9 shows the evolution of enzymatic activities of these compositions. It is found that the orange terpene (MPR4 composition) and a C8-C16 glucoside (MPR1 composition) are two MPR that stabilize the enzyme very strongly. It is also found that the dipropylene glycol monomethyl ether (composition MPR7) gives a better stability than the ethoxylated fatty alcohol C12-C13.8OE (composition MPR6). The glycol ether is present in the formulation because its degreasing role is essential.
