Claim:
1. A process for producing a composition of biodegradable surfactants comprising sodium hydroxide 1N, potassium chloride, sulphonic acid, dodecanoic acid, nonylphenol, terpene-1 and water, comprising the following steps: combine an amount of hard water less than 50% v/v in respect of the total volume of the composition, 2.5-5.5% v/v of sodium hydroxide 1N, and 2-4% v/v of potassium chloride; add 5-15% v/v of sulphonic acid, 3-6% v/v of dodecanoic acid, and 3-8% v/v of nonylphenol of 4-10 mols, and shake the mix until it is homogeneous; once homogeneity is achieved, complete the total volume to 100% v/v with hard water, mixing continuously; let stand for 24 hours; after the 24-hour standing period, extract 60-80% v/v of the mixture and mix it with 20-40% v/v of terpene until a white homogeneous mixture is formed; and let stand for at least 6 hours.
