makingcosmetics ® Updated: 10/26/2018 Lactic Acid Specification Sheet Description : Lactic acid is a naturally occurring alpha hydroxy acid (or AHA) produced by fermentation of milk. It is the alpha hydroxy acid most frequently used for peel products. Synonym: 2-hydroxypropanoic acid. Clear, water-white viscous liquid. Characteristic odor. Concentration: 88% (12% water). Grade: CG. pH Value 0.5. Easily soluble in water. CAS : 50-21-5, 79-33-4 INCI Name : Lactic acid Benefits : Very useful to rejuvenate the skin by encouraging the shedding of old surface skin cells Can reduce the appearance of fine lines, irregular pigmentation, age spots & decreases enlarged pores Good choice for first-time peel users or for those with sensitive skin Often used in creams & lotions at a lower concentration for a more gentle acid-based peel. Use : Typical use level is between 1-20%. Important : Do not use lactic acid pure and undiluted; the solution is highly acidic and can lead to skin irritation and skin burns. Storage: stable ~1 year, store cool & light protected. External use only. Please note that when using this ingredient regularly in skin care products, the skin will be very sensitive and needs to be protected from the sun, wearing sunscreen or any other protection. Applications : Peels, creams, lotions, masks, cleansers. Due to its acidity the final product needs to be tested for safe pH. Optimal pH range from 3.5-5.0. Some over the counter products, after adding lactic acid, will separate as a result of the low pH, and need to be stabilized. Country of Origin : USA Raw material source : Corn starch and various sugars Manufacture : Lactic acid is produced by bacterial fermentation (various Lactobacilli ) of carbohydrates (sugar, starch). Pure sucrose, glucose from starch, raw sugar beet juice are frequently applied. Animal Testing : Not animal tested GMO : No data available Vegan : Does not contain animal-derived components MakingCosmetics Inc. 10800 231 st Way NE, Suite 100, Redmond WA 98053 Phone 425-292-9502 Fax 425-292-9601 www.makingcosmetics.com .

SCCNFP/0370/00, final The Scientific Committee on Cosmetic Products and Non-Food Products intended for Consumers (SCCNFP) has been requested to give an opinion on the safety of alpha-Hydroxy Acids in cosmetic products. The attached Position Paper of the SCCNFP has been prepared in this respect. The Commission services invite interested parties for their comments. Please send your comments before 15 September 2000 at the following e-mail address : [email protected] SCCNFP/0370/00, final The safety of alpha-Hydroxy acids ____________________________________________________________________________________________ THE SCIENTIFIC COMMITTEE ON COSMETIC PRODUCTS AND NON-FOOD PRODUCTS INTENDED FOR CONSUMERS. POSITION PAPER CONCERNING THE SAFETY OF ALPHA-HYDROXY ACIDS Adopted by the SCCNFP during the 13th plenary meeting of 28 June 2000 2 SCCNFP/0370/00, final The safety of alpha-Hydroxy acids ____________________________________________________________________________________________ 1. Terms of reference The safety of α-hydroxy acids in cosmetic products has been questioned by some Member States with respect to their dermal tolerance. Hydroxy acids have a long history of use in dermatological preparations and recently have become important ingredients in cosmetics. Concerns on both the dermal and systemic safety of these materials has led to calls for their listing in Annex III (List of substances which cosmetic products must not contain except subject to restrictions and conditions laid down) to the Cosmetics Directive 76/768/EEC. 2. Position of the SCCNFP Definition of AHAs AHAs are carboxylic acids substituted with a hydroxyl group on the alpha carbon. The AHAs most commonly used in cosmetic products are glycolic acid and lactic acid.

Nam Virgil J. Flanigan iii ABSTRACT Alpha hydroxy acids (AHAs) – carboxylic acids with a hydroxyl substitution on the alpha carbon are an important class of molecules. Hydroxy Methyl Thiobutanoic Acid (HMTBA) is an α-hydroxy analog of essential amino acid methionine; it finds extensive use as a feed supplement for avian and bovine species. Efficacy of alpha hydroxy acid uptake is important for nutritional studies and such studies rely on accurate and precise methods for determination of these chemicals in biological samples.

Alpha Hydroxy Acids
DianaYvonne Skin Care Characterize by light to moderate penetration, and minimal or no discomfort. These peels/exfoliators are excellent at improving the texture of the skin and evening out the skin tone. For maximum results, they can and should be alternated. Alpha Hydroxy Acids: While Glycolic and Lactic acid peeling agents have equivalent results, the following shows that lactic acid peels have many benefits over glycolic acid peels. Glycolic Acid is the most commonly used AHA. Because of its small molecular weight and size, it is presumed to have a better capacity to penetrate skin. Lactic acid on the other hand, has a larger molecular weight than glycolic acid but is capable of being converted into pyruvic acid (an alpha keto acid) which is presumed to be a more effective exfoliating agent. Lactic Acid: Lactic Acid is a normal metabolite for mammals. It has no toxicity. With its longer reaction time, lactic acid is safer than glycolic acid. There is a better control of the peel without burning. Lactic acid enhances the absorption of other substances and is a superb humectant -- it attracts water molecules already present in your skin to the surface, making it an effective moisturizer. There is a minimal chance of adverse effects. Glycolic Acid Glycolic Acid is of vegetable origin (non-mammalian). There is a rapid reaction time. There is less control of peel irritation. In working with the higher clinical strengths 70%, there have been many reported incidents of adverse effects, like discoloration and scarring. GLYCOLIC ACID is an alpha hydroxy acid derived from sugar cane.

No. 5-1, Marunouchi 1-chome Chiyoda-ku Tokyo (JP) (54) Process for producing alpha-hydroxy acid or alpha-hydroxyamide by microorganisms. (57) A process for the production of a-hydroxy acids or a-hydroxyamides in which an a-hydroxynitrile compound or a mixture consisting of an aldehyde and prussic acid, which corresponds to the nitrile compound, is allowed to undergo a microbial reaction to produce the corresponding a-hydroxy acid or a-hydroxyamide, wherein the improvement resides in that phosphite ions or hypophosphite ions are allowed to be present in the reaction system. According to the present invention, since hydrolysis or hydration of nitrile compounds can be carried out by constantly keeping a low concentration level of aldehydes which are considered to be a cause of the enzyme inhibition in the reaction system, the enzyme activity can be maintained stably for a prolonged period of time and the formed acids or amides can therefore be accumulated in a high concentration.

After discussing the various possible mechanisms of depigmentation, the different molecules that can be used as well as the status of the products containing them will now be presented. Hydroquinone and derivatives thereof, retinoids, alpha- and beta-hydroxy acids, ascorbic acid, divalent ion chelators, kojic acid, azelaic acid, as well as diverse herbal extracts are described in terms of their efficacy and safety. Since a genuine effect (without toxic effects) is difficult to obtain, prevention by using sunscreen products is always preferable. Keywords: depigmenting agents; safety; efficacy 1. Introduction The allure of a pale complexion is nothing new and many doctors have been looking into this subject for some time, proposing diverse and varied recipes for eliminating all unsightly marks (freckles and liver spots were clearly targeted). Pliny the Elder (Naturalis Historia), Dioscoride (De Universa medicina), Castore Durante (Herbario nuove), and other authors from other time periods have addressed this issue.
