The personal care industry is in the middle of a quiet but significant reformulation wave. Brands from mass-market to luxury are revisiting their cleansing, conditioning, and moisturising formulations not because their products stopped working, but because the ingredients they relied on no longer fit where consumer expectations and regulatory pressures are heading.
At the centre of this shift is a class of ingredients that has been hiding in plain sight: amino acid-derived compounds. Glycine, in particular, has emerged as one of the most versatile and commercially viable of these a molecule that does multiple jobs in a formulation, plays well with other ingredients, and carries a consumer-friendly profile that synthetic alternatives simply cannot match.
Conventional surfactants SLS, SLES, and their derivatives are effective cleansers. They have been the backbone of personal care formulations for decades. The problem is not efficacy. The problem is that effectiveness at removing dirt also means effectiveness at stripping natural oils and disrupting the skin's moisture barrier.
For everyday products that are used twice daily face washes, shampoos, body washes this cumulative stripping effect has become a formulation liability. The rise of 'skin barrier' as a consumer concept (now mainstream, not niche) has put formulators under genuine pressure to find alternatives that clean without compromising.
Glycine is the simplest amino acid, and its chemistry makes it an unusually useful tool for formulators. It contributes to personal care formulations in three distinct ways:
As a Direct Skin Conditioning Agent
Glycine can be used directly in formulations as a moisturising and conditioning ingredient. It helps maintain skin hydration and supports the natural amino acid profile of the skin's Natural Moisturising Factor (NMF) the complex that keeps skin plump and resilient. This makes it a genuine functional ingredient, not just a label claim.
As a Building Block for Amino Acid Surfactants
N-acyl glycinates surfactants derived from glycine represent one of the fastest-growing categories in cleansing formulation. They are mild, effective, and biodegradable. They foam gently, rinse cleanly, and are significantly better tolerated by sensitive and compromised skin than conventional alternatives. Products like sodium cocoyl glycinate are already appearing in premium cleansing formulations globally.
As a pH Buffer and Formulation Stabiliser
Glycine's ability to stabilise pH across a range of conditions makes it useful in formulations where pH management is critical which, in personal care, is most of them. Maintaining the skin's natural acidic pH is central to barrier function, and glycine helps formulators hit that target more reliably.
Sensitive skin is no longer a niche consumer segment. Studies consistently show that a significant proportion of consumers often cited at 50% or more across markets self-identify as having sensitive skin. This has made mild, compatible ingredients a mainstream formulation priority rather than a premium add-on.
Glycine-based ingredients sit at an almost ideal position for this market: they are genuinely mild (not just marketed as mild), they are well-documented in terms of safety and compatibility, and they come with a natural amino acid story that resonates with ingredient-conscious consumers.
Beyond performance, glycine offers two other advantages that are becoming increasingly important in procurement decisions:
REACH Compliance
For formulators supplying EU markets, REACH-registered raw materials are increasingly expected. A glycine supplier with full REACH registration removes a significant compliance burden from your formulation team.
Biodegradability and Clean Label
Amino acid-based ingredients biodegrade more readily than many synthetic alternatives. They also carry a cleaner label story 'amino acid derived' reads very differently to consumers than a chain of chemical abbreviations. For brands positioning themselves in the natural or clean beauty space, this has real commercial value.
Avid Organics produces the AviGly™ series specifically to meet the requirements of cosmetic and personal care applications. The cosmetics-grade AviGly™ delivers consistent purity suitable for leave-on and rinse-off formulations, with full REACH registration and documentation to support regulatory filings in key markets.
For formulators working on bio-based formulation projects, AviGly™ Bio HP is the natural choice offering the same cosmetic-grade performance from a production process that meets the bio-based sourcing criteria increasingly required by EU and sustainability-focused brands.
Avid's in-house R&D team works directly with formulators on application-specific questions concentration ranges, compatibility testing, pH optimisation treating the relationship as a technical partnership rather than a product transaction.
If you are evaluating glycine or glycine-derived surfactants as part of a formulation review, here are the practical starting points:
Start with a mildness-driven application: facial cleansers, baby care, and sensitive skin products offer the clearest value proposition for amino acid-based ingredients
Check compatibility with your existing co-surfactant system glycinates blend well with other mild surfactants and can be used to moderate the profile of stronger cleansing agents
Review regulatory status in your target markets your supplier should be able to provide documentation to support this
Request a technical data sheet and CoA from your supplier before finalising grade selection
Consider the consumer communication angle amino acid-derived ingredients carry a story that translates well to packaging and marketing claims
The reformulation conversation has moved from 'should we look at amino acid ingredients?' to 'when are we switching?' For brands in the premium, natural, sensitive-skin, and EU-facing segments, that timeline is accelerating.
Glycine, and the amino acid chemistry it enables, offers formulators a rare combination: better skin compatibility, a credible sustainability narrative, regulatory alignment, and a consumer story that does not require a chemistry degree to understand. That is a genuinely unusual convergence and it explains why so many formulation teams are paying attention.
